Document Conventions and Menu Navigation
Commands are selected with the supplied infrared remote or the RS232 serial port. To prevent possible
command conflict, only one of these methods of command should be used at a time. See the Serial RS232
Command Interface section for information on serial commands. The infrared remote-control command
notation is described below:
•Remote buttons are named as shown in a bold font. Example: MENU.
•For comma separated lists, press the buttons in the sequence shown.
•For parenthesized lists, select one button from the list.
•For square-bracketed lists, press the buttons as needed.
Example: For the list [, , , ], press the arrow keys as needed.
•For menu commands press the MENU button. The and arrow keys are used to select the
function. The arrow key (or OK) is used to enter sub-menus. This is shown as: MENU →
MenuItem →MenuItem. Generally, the arrow key (or EXIT) steps up one menu level.
•Numerical entries are listed as value. For numerical entries, the arrow key acts as backspace.
•Some commands are activated immediately without the need to press OK. Other commands must
be explicitly accepted by pressing OK. If needed, OK is listed as part of the command, and will
complete the command and return the menu to one level higher in the menu system. Note that,
at default settings, pressing OK when it is not required will bring up the Radiance Status Screen.
•For many commands, pressing EXIT cancels a partially completed command and returns to one
level higher in the menu system. For advanced commands changes are completed from within
the command and EXIT just returns to one level higher in the menu system.
•There are four independent configuration memory types for each input (MEMA, MEMB, MEMC
and MEMD). The input setup and output resolution/timing can be set independently for each
memory. To program an input memory, first select the input, then select the desired
configuration memory and use the menu system to configure.
•Some menu commands are only available when their associated input is selected.
•Before changes are saved, they can be discarded by entering standby (STBY) mode.
•A Save must be performed after any changes or all changes will be discarded the next time the
unit enters standby (STBY), or power is lost. To save press MENU, , OK, OK, OK.
Unpacking
•Unpack the box.
•Save the box and packing materials in case you need to ship your Radiance.
Verify that your box contains the following items
•Lumagen Radiance video processor.

Block Diagram
The function of the Radiance is to act as a video switch, process the selected video source, and then output
video in the appropriate format and resolution. Input rates from standard definition up to 4k60 are
supported. Video inputs are converted to progressive video, if necessary, and are then scaled to the video
output resolution, which can be up to 4k60.
Interlaced video has been in use for more than 60 years and is still a common video format. It displays half
of the lines of picture information each sixtieth (or fiftieth) of a second. Each half of the image is called a
field and displays either all the even lines, or all the odd lines. So, an entire image, called a frame, takes a
thirtieth (or twenty-fifth) of a second to display on the screen. An “i” suffix on the resolution specification is
used to indicate interlaced formats.
In contrast, progressive video presents each frame as a whole. A “p” suffix on the resolution specification is
used to indicate progressive formats. Converting interlaced video to progressive video is referred to as
“deinterlacing.”
The Radiance is comprised the following major functional sections:
•Video/Audio input selection
•Video deinterlacing (if required)
•Video processing and scaling
•Video/Audio output
The functional blocks are shown below. Note that the number of HDMI inputs and outputs can vary. The
Radiance Pro 4242 four-input, two-output, configuration is shown.
Commands can be sent to the Radiance by infrared remote or via the serial RS232 port. The RS232 port, or
the USB port, can be used for software updates. Setup is done with the on-screen menu. User functions
(e.g. select input) use direct commands to make macro programming simpler.

Configuration Memories
To understand how the Radiance functions, it is important to understand that setup and calibration
parameters are split into “input memories” and “output configurations.” Input memories control the video
source setup. Output configurations control the display setup and calibration. The Input Memory selects the
Output configuration for that input, and input memory by selecting a Config, CMS and Style for each input,
input memory, input resolution, HDR/SDR, and/or 2D/3D mode.
Each Radiance Pro input has four input memories (MEMA, MEMB, MEMC and MEMD). Each input memory
has sub-memories for each supported input resolution and rate which are automatically selected based on
the input resolution and vertical-rate. The “Other” entry is selected for input resolutions and vertical rates
not specified explicitly. Each input resolution and vertical rate has 8 sub-memories which are programmable
on a per-input and per-input-memory basis. For example, as shown in the block diagram below there can be
8 different input configurations for 480i/p sources. Different inputs and input memories can each be
independently programed to one of the 8 sub-memories for each listed resolution and vertical rate.
Each input sub-memory can be independently linked to any one of the 8 Output Mode configurations, 8
CMS memories, and 8 Style memories. These store setup data for the video display setup and calibration.
In the factory default condition all input sub-memories are linked to Auto output Mode, CMS 0 (for SDR
sources), CMS 1 (for HDR/Rec2020 sources), and Style 0.
To change these linkages use the Output Setup menu. Settings can be changed for each input sub-
memory. Make sure to “Save” any changes you want to keep (MENU →Save →OK →OK →OK).
NOTE:
By default, for a Rec 709 source, all sub-memories point to Auto output mode
CMS0 and Style0. For a HDR/Rec2020 source, all sub-memories point to Auto
output mode, CMS1 and Style0. For the majority of systems this default set of
configuration pointers does not need to be changed.
NOTE:
Changes must be Saved. If changes are not Saved the Radiance Pro will revert
to the previously Saved settings when turned off. So, if you make a
configuration mistake you can revert to Saved settings with a Power Cycle.

Section 3 –Quick Start Guide
Installation Instructions
1. Install two AAA batteries in the Lumagen Remote Control.
2. Disconnect all power in the system before connecting any A/V cabling to minimize the chance
of damaging equipment.
3. Connect audio/video sources as appropriate.
NOTE:
Using the highest quality 18 GHz “Certified” HDMI cables is essential for proper operation. For Radiance Pro
HDMI connections use 6 to 10 foot (2 to 3 meters) passive 18 GHz “Certified” HDMI cables such as the
Tributaries UHD or Ethereal Velox. For Radiance Pro output lengths over 10 feet (3 meters) Lumagen
recommends using a 18 GHz fiber HDMI cable such as the RUIPRO (amazon.com), or the Tributaries active
UHDT “Titan” cable.
NOTE:
The default configuration is, as shown below, to connect Radiance Pro HDMI Output 1 to the audio receiver,
and HDMI Output 2 (424X) or Output 4 (444X) to the primary TV or projector. This configuration insures EDID
information for audio and video are read and passed back to sources as appropriate. Lumagen recommends
that the Radiance be used as the switching device for ease of operation, fastest video switching, and best
video quality.
Default connections for Radiance Pro 4242 with AVR plus display/projector
4. Connect the Radiance outputs. If using an AVR, or audio PrePro, connect it to Radiance Pro
Output 1 the display/projector to Output 2 (424X), or Output 2 or 4 (444X). If using only one
Radiance output, connect the display to the highest numbered output. Then, if necessary,
change the highest numbered output to both audio and video (using the Output->Output
Setup menu), and enable the appropriate audio modes manually (See Direct Commands, MENU
0943 and MENU 0944), and do a Save.
5. Reconnect power. Plug the DC power cord from the Radiance power supply into the DC power
jack on the back of the Radiance. Then connect the power cord to the Radiance power supply
and plug it into a wall outlet.
6. Turn the other equipment on and use the Radiance remote control to turn the Radiance on.
7. Select the desired Radiance input using the Radiance remote control. The video inputs are
numbered from 1 to 8. To select and input press the “Input” button and then press the
corresponding number button on the remote. Make sure the selected source device is
outputting active video.
8. You should now have an image on your display/projector. The Radiance automatically selects
the appropriate output resolution and frame rate for HDMI/DVI displays/projectors (including
24p when supported), when connected according to these instructions.
9. The default output aspect ratio is 16:9 (i.e. 1.78:1). No output aspect ratio selection is needed
for 16:9 displays or projectors. For other output aspect ratios, please see the User Manual for
information on how to set the output aspect ratio. For 2.35 anamorphic screens the Radiance
Pro can control the aspect ratio without the use of an anamorphic lens. See Tech Tip 16 for
information on how to set up the Radiance Pro for a 2.35 screen.

Section 4 –System Configuration Examples
The most common configurations using the Radiance are shown below. Note, examples below refer to the
Radiance Pro 424X units. For the Radiance Pro 444X, use Output 1 for the AVR and Output 4 for the TV/projector.
1. Receiver after Radiance (most common configuration)
The default configuration is to connect all the video sources to the inputs of the Radiance Pro and connect the
receiver, or preamp, to HDMI Out 1, and the display/projector to Radiance HDMI Out 2 (424X) or Output 4 (444X).
Only after all audio and video connections have been made, connect power and turn everything on. The Radiance
automatically detects the video EDID from output 2 (424X) or Output 4 (444X), and the audio EDID from output 1
and reports the appropriate EDID modes back to all source devices. You can manually override this behavior.
By default, Output 1 is set to “Audio Only”. With this setting, Output 1 will output audio with blank 1080i or 720p
video. In the “Output Setup” menu, for 9 GHz output cards, you can change the settings for each output to “Audio
Only”, “Video Only”, “Both Audio and Video”, or “No Audio or Video.”For 18 GHz output cards, the odd numbered
output is always Audio-only, or off. If the odd output is enabled for audio the even numbered output is always
both audio and video at up to 18 GHz. If the odd numbered output is off, then the even numbered output can be
programmed for video only, or both video and audio, at up to 18 GHz using the Output Set Menu.
This configuration can improve switching delays by using the Radiance Pro’s input switching and guarantees that
the receiver does not degrade the video. It also minimizes the work needed to configure the Radiance, for the
TV/projector output, because audio is off by default.
2. Audio and Video routed separately
Route the audio and video separately to the Radiance and a receiver. Connect the TV/projector to Output 2 (424X)
or Output 4 (444X). This output has its audio turned off by default and so is correct by default for this case.
3. Receiver in front of Radiance
You can use an AVR in front of the Radiance to switch the video sources. Note that some AVR’s add artifacts to the
video. So turn off all video processing in the AVR. Connect the TV/projector to Output 2 (424X) or Output 4
(444X). This output has its audio turned off by default and so is correct for this case.

Section 5 –Basic Commands
Power
Turn power on by pressing the ON button. Place the Radiance in standby-mode by pressing STBY.
Input Selection
Press the INPUT button and then press the corresponding input number button on the remote.
Shortcut:
If the menu or status is not displayed on the screen, a new input can be
selected by pressing the corresponding number button on the remote.
Configuration Memory Selection
Each input has four configuration memories. These are referred to as memory “A”, “B”, “C” and “D”. To select one
of these memories press MEMA, MEMB, MEMC, or MEMD, respectively. Note, RS232 codes are provided to
directly access these memories. Each input memory has eight input “sub-memories” that are automatically
selected based on the input resolution and 2D/3D input video format.
Each configuration memory, and sub-memory, is independent of the other memories. To allow the memories to be
used for mode selection (i.e. day/night), by default, the memory type remains unchanged when a new input is
selected. (i.e. If input 2 memory B is active, pressing “INPUT, 3” selects input 3 memory B).
Input Aspect Ratio Selection
NOTE:
Make sure the “display aspect ratio” is set to 16:9 in the setup menu of all video sources (e.g.
Bluray players or set top boxes), even if your display is not 16:9.
The input source aspect ratio can be selected by pressing one of the 4:3, LBOX, 16:9, 1.85, or 2.35 aspect
buttons. To use the NLS feature, press “4:3, NLS”, “16:9, NLS”, or “1.85, NLS”.
•Use 4:3 for standard definition full-screen material.
•Use LBOX for “letterbox” standard definition material, such as analog-television movies shown with black
bars above and below the image.
•Use 16:9 for material labeled as “Enhanced for 16:9 televisions”.
•Use 1.85 for material labeled as “Aspect ratio 1.85”.
•Use ‘Alt’ 1.85 for material that is “Aspect ratio 1.85 letterboxed in a 16:9 (1.78) window”.
•Use ‘Alt’ 4:3 for material that is “Aspect ratio 2.00 letterboxed in a 16:9 (1.78) window”.
•Use ‘Alt’ 16:9 for material that is “Aspect ratio 2.20 letterboxed in a 16:9 (1.78) window”.
•Use 2.35 for material labeled as “Aspect ratio 2.35”.
•Use ‘Alt’ 2.35 for material labeled as “Aspect ratio 2.40”.
•Use NLS to apply a horizontal non-linear stretch, to stretch 4:3 to 16:9, or 16:9 or 1.85 to 2.35 or 2.40.
Image Zoom
After the input aspect ratio has been selected, the image can be zoomed in to better fit the screen. The zoom
function uses the and arrow buttons. When the menu is off, by default, the arrow button zooms in by
about 15% and the arrow button zooms out by about 15%. The Zoom amount can be changed to 5% steps.

Pressing “OK” when the information screen is displayed, will display several additional status screens.
NOTE:
The OK button is equivalent to the RS-232 <cr> character (carriage return). Sending a <cr>
character after a command that does not explicitly require it is treats it as a separate command
and will bring up the status screen. When using RS-232 control do not send a <cr> unless it is
required by the command being sent. If the control code has been written such that
unnecessary <cr> characters are being sent you can disable this “Status on <cr>” feature by
entering MENU 0927 and doing a Save.
On-Screen Help
Pressing, “HELP”when the menu is displayed, displays on-screen help information, for the currently highlighted
menu item, for many of the menu options. Additional information is displayed which can enhance your
understanding of the settings and choices.
Quick Keys
Provides a menu to use for basic remotes that have limited buttons, The ‘Quick Keys’ menu has buttons for input
aspect ratio (4:3, LBOX, 16:9, 1.85, 2.35, NLS), set zoom (Zoom+, Zoom-) and select the user memory (MemA,
MemB, MemC, MemD). The “Quick Keys” menu duplicates the function of pressing the corresponding buttons on
the Lumagen remote. There are also buttons to control 3D (off, SbyS, TopB).

Section 6 –Video Output Menu
By default the output is set to “Auto 2” (424X) or “Auto 4” (444X). “Auto 2” means the Radiance automatically
reads the video EDID from the devices connected to Output 2, and automatically selects the appropriate output
resolution.
For “Auto” modes the output vertical rate is selected based on the input vertical rate. For example, input formats
480i60, 720p60, and 1080i60 automatically select a vertical output rate of 60 Hertz. Input formats 576i50, 720p50,
and 1080i50 automatically select a vertical output rate of 50 Hz. For a 24p input formats, a 24p output vertical rate
is selected, if the display supports a 24p vertical rate, otherwise a 60 Hz output rate is selected.
Video Output Setup Menu
The Video Output Setup menu is used to select output settings ( Mode , CMS , and Style ) based on the input
number, input memory, and input video resolution and rate. The Video Output Select Menu does not affect the
audio settings. See the Audio Configuration section for information on configuring audio modes.
NOTE:
The Video Output Setup Menu is not needed for typical systems
To select the output settings based on input, input memory, and input video mode, press MENU →Output
Setup→Ok. This will display the Input Conditions and Output Selections.

the input number, input memory, and input mode. When making settings that apply to multiple input conditions
you can leave any of the output settings unchanged by selecting the ‘---‘ option for that output setting. The 9 GHz
Video Output card has selections for “A” audio only, “B” both audio and video, “V” video only, “N” no output, and
“-“ to leave unchanged.
NOTE:
For the 18 GHz output card, the odd output is audio-only or off. The even output
is always audio and video if the odd output audio is enabled, and can be audio
and video, or video only, if the odd numbered output is off.

Custom Output Mode
Custom Modes store settings for the timing of HDMI video mode that drives the display. There are menus to select
standard HDMI modes or custom timings. NOTE: By default, the Radiance Pro automatically selects the
appropriate output modes based on the EDID reported by the display on the primary video output.
Output Mode –Direct Commands
Note that these direct commands are meant as temporary overrides, not as permanent selections and affect only
the current input, input resolution and input memory. The Output Setup menu should be used to program the
output modes if the Auto output mode is not being used. The direct commands to select output resolution are:
480p60: MENU 0 2 1 OK 720p60: MENU 0 2 4 OK 1080p24: MENU 0 2 0 OK
1080p60: MENU 0 2 7 OK 4k24: MENU 0 2 3 OK 4k50: MENU 0 2 5 OK
4k60: MENU 0 2 9 OK
Custom Mode Timing
If a Custom Output Mode Output Timing is selected using the Output Setup Menu, its timing can be modified on a
pixel basis. Do not change the timing using this menu unless it is really needed.
Warning:
Some digital displays lose picture if the timing is changed by even a single pixel.
The command is:
MENU →Output →Custom Modes →[Custom] →Mode Timing
Output Label
You can change the output mode labels. Use the and buttons to highlight a letter. Use the and buttons
to change the letter. Capital letters, small letters, numbers, symbols, and blank are available. The command is:
MENU →Output →Custom Modes →[Custom] →Label
CMS Menu
The Color Management System (CMS) stores settings used to calibrate the color of the display. There are menus to
calibrate the position of the primary/secondary color points, calibrate grayscale tracking, calibrate the gamma
curve, and compensate for red/green push errors.
Gamma Factor
The Gamma Factor adjusts the gamma curve of the Radiance video output up or down. The Radiance is in the
middle of the video chain and the default setting of 1.00 leaves the output gamma unchanged. Changing the
Gamma Factor allows the Radiance to make a “coarse correction” of the display Gamma. It should be set to
(Desired_Gamma / Measured_Gamma). Note: You should check and potentially adjust the Black Level after
adjusting the Gamma Factor. The command is:
MENU →Output →CMS’s →[CMS] →Gamma Factor
Color Gamut
Allows primary and secondary color point calibration, or calibration of 4913-points throughout the RGB color cube,
using a 3D color lookup table (3D LUT) Color Management System (CMS). You must enable Service Mode to make
changes using this menu.
Note:
A color probe, appropriate calibration software, and proper training is needed for correct adjustment.
Making manual changes is not recommended.
The command is:
MENU →Output →CMS’s →[CMS] →Color Gamut

Section 6 –Video Output Menu
Copyright 2007-2017 Lumagen, Inc Radiance Pro, Rev 071719
16
Colorspace
Select the output Colorspace. The choices are Auto, HDR2020, SDR2020, SDRP3, SDR709, and SDR601. The
default setting of “Auto”sets the output color space to match the input dynamic range and colorspace. For HDR
you can select “SDR2020”, “SDRP3,” or “SDR709.” The best choice depends on the native “color Gamut” of the
display, and if you are going to do a 3D LUT calibration. See the HDR Mapping sections for more information.
“SDR601” is generally not used because the Pro converts SD input sources to Rec 709. The command is:
MENU →Output →CMS’s →[CMS] →Colorspace
Grayscale and Gamma
Allows the parametric adjustment of 2, 5, 11, 12 or 21 color temperature points to adjust the grayscale and
gamma for the display. You need a colorimeter and preferably color calibration software to use this command. The
command is:
MENU →Output →CMS’s →[CMS] →Gray/Gamma
Color Decoder
Used to correct color decoder errors in the display that have red and/or green push. This adjustment is generally
not used in conjunction with Color Gamut 3D LUT based calibration. However, if you know your display has a color
decoder error, you can use this command before the 1D and 3D LIT calibration to compensate for the color
decoder error. The command is:
MENU →Output →CMS’s →[CMS] →Color Decoder
Black Level
This command allows for accurate calibration of the black level. Normally the “Brightness” (or “Black Level”)
control in the display is used to set the black background level, and then the Radiance Pro Adjustable Contrast 2
pattern is used to set the black video reference. This command is also useful when a second black level is desired
(using a second output CMS) for a “day” or “night” mode. The command is:
MENU →Output →CMS’s →[CMS] →Black
White Level
Used to set the white level for the display. Normally the “Contrast” control on the display is used to set the white
level. It is recommended that the Radiance Contrast Pattern 1 (White and Black squares pattern) be used to set
the display’s white level. The command is:
MENU →Output →CMS’s →[CMS] →White
HDR Tone Mapping Initial Setup
HDR Intensity Mapping can map an HDR source for optimal viewing on either a HDR or SDR TV or projector. It is
always disabled for SDR sources. Note that by default the CMS1 output configuration memory is automatically
selected for HDR sources. When using the Radiance Pro Tone Mapping, HDR source output should be selected as
SDR and HDR Mapping enabled.
NOTE:
A key concept to understand for HDR sources and HDR Tone Mapping is that data manipulation in the
pipeline does not always have to be in “HDR Gamma.”Just as DCI/P3 movies are put into a “Rec
2020 container” for HDR, it is possible to put the HDR Gamma into a “SDR container” if this is
accounted for so that the onscreen image is correct. This is not somehow converting HDR to SDR.
Instead it is putting the “HDR in an SDR container.”
Set the CMS1->Colorspace->Colorspace to SDR2020, SDRP3, or SDR709. Which one is best for your system
depends on the native color Gamut of the projector/TV, and whether a 3D LUT calibration will be completed. If
your projector has a color Gamut limited to Rec709, select SDR709 independent of if a 3D LUT calibration is
planned, or not. If your projector/TV color Gamut exceeds P3 you may want to select SDR2020. If, and only if, you
plan to a 3D LUT calibration, and your projector/TV has a color Gamut near P3, then you may want to choose
SDRP3 as the Output Colorspace.
Set the CMS1->Colorspace->HDR Flag to off for CMS1, unless you have a JVC projector. If you have a JVC
projector you can select the HDR Flag = On in CMS1, to select a different projector memory for HDR than is used
for SDR. Then make sure to select the projector Gamma as 2.4 (rather than Bt.2084) in the JVC projector memory
selected when the HDR flag is asserted so the projector’s tone mapping is disabled.

Section 6 –Video Output Menu
Copyright 2007-2017 Lumagen, Inc Radiance Pro, Rev 071719
17
Set the CMS1->Colorspace->2020<->601/709 to Auto Convert . If Auto Convert is enabled and the output
colorspace is different than the input colorspace, the Radiance Pro automatically converts the data to appropriate
values for the selected output Colorspace. For example, if you have a projector that is limited to a Rec709 color
Gamut, select the output Colorspace as SDR709, and enable auto convert the Radiance Pro will convert the data so
that the HDR “2020” colors within the physical Rec 709 limit of the projector appear correctly to the best ability of
the projector.
HDR Intensity Mapping is disabled by default. It is enabled in Output->CMSs->CMS1->HDR Mapping
menu. When you enable HDR Intensity Mapping you should also select the output CMS1->Colorspace as an
SDR mode.
Changing the Display Max Light adjusts the HDR source to display light ratio. The Display Max Light is set in
the same menu. You can increase or decrease the Display Max Light using the arrow keys in 100 nit steps, or
you can use the number keys to enter a value from 50 to 9990 in 10 nit steps.
With HDR Intensity Mapping control parameters at default values, use the Display Max Light as a coarse
“brightness” control while watching a (paused) very bright scene.
See the Video Input Menu and Calibration sections for more information on adjusting Display Max Light.
The command is:
MENU →Output →CMS’s →[CMS] →HDR Mapping
CMS Label
You can change the CMS memory labels. Use the and buttons to highlight a letter. Use the and buttons
to change the letter. Capital letters, small letters, numbers, symbols, and blank are available. The command is:
MENU →Output →CMS’s →[CMS] →Label
Styles Menu
The Style memory stores settings for the HDMI format used to drive the display. There are menus to set the HDMI
format, size, position, aspect ratio, and gray-bars for the image on the display. These output styles (Style0 through
Style7) can be selected for use in the Output Setup menu.
HDMI Output Type
You can specify the digital output range as “RGB-PC level” (e.g. for 8-bit 0 to 255) or “RGB-Video level” (e.g. for 8-
bit 16 to 235). “YCbCr 422” is the recommended output format. For the HDMI RGB output, setting the level as
video allows blacker-than-black and whiter-than-white video levels to be output from the Radiance. The command
is:
MENU →Output →Styles →[Style] →HDMI Format →Type →(Auto, RGB/Level=Vid,
RGB/Level=PC, RGB/36bpp Dual Out/Level=Vid, YCbCr444, YCbCr422)
Note that for some output rates (e.g. 4k60 using 9 GHz output cards) the mode may not be programmable. For
reference the 4k60 output mode using 9 GHz I/O cards is always 4:2:0, 8-bit. Note that the RGB/36bpp is
supported only for 9 GHz output cards.
Rate Match
Often streamers use a 60.00 Hertz output rate for their OSD, instead of the video standard of 59.94. In addition, a
small fraction of source material is sourced at 24.00/60.00 Hertz refresh rates instead of the standard 23.98/59.94
Hertz rates. In this case it may be desirable to slightly alter the output rate to match the input rate. However,
operation is smoother, and switching faster, if these are output at the video standard rates.
While the difference between 59.94 and 60.00 is small, if the OSD is 60.00 and the video 59.94 an HDMI output
restart is necessary due to the change in frequency. To eliminate this, you can select Rate Match = No. Note, that
if you watch material that is truly 60.00 or 24.00, there will be some dropped frames with this setting.
Most people are not sensitive to this, but other are. If you are sensitive you can instead leave Rate Match enabled.
The default setting is 'Yes.' The command is:
MENU →Output →Styles →[Styles] →HDMI Format →Rate Match
