■Pixel-to-Pixel Mode
Use this setting to enable Pixel-to-Pixel mode.
This mode bypasses the monitor’s internal scaling function and displays images in their native resolution and aspect ratio,
with a one-to-one mapping of incoming image pixels to screen pixels:
• For incoming formats smaller than the native resolution of the window (or selected aspect ratio), the image will be
displayed in the center of the window using only the necessary LCD pixels. For example, 480i images will only occupy
exactly 640x480 pixels in a particular channel window in DLW mode, or if the channel is selected full screen, it will
occupy exactly 640x480 pixels in the center of the screen. The surrounding screen area will be black.
■Aspect Ratio Settings
Use this menu option to switch between several aspect ratio settings.
As the V-R902DLW monitor has a native resolution of 1366x768 RGB pixels, incoming images are automatically scaled to fit
the screen:
• In 4:3 mode, images are scaled up or down to fill the maximum 4:3 portion of the screen. IMD text and time code are
superimposed on the lower portion of the image. The audio presence indicator and on-screen tally are displayed at the
bottom of the screen, outside the image.
• In Scaled 4:3 mode, images are scaled to a smaller 4:3 portion of the screen, leaving space for IMD text, tally, and audio
presence indicator to be displayed below or around the image. Time code is superimposed on the lower portion of the
image.
• In 16:9 mode, images are scaled to fill the maximum 16:9 portion at the top of the screen. In this mode, IMD text and
on-screen tally are displayed below the image. Time code and the audio presence indicator are superimposed on the
lower portion of the image.
• In Full Screen (16:10) mode, images are scaled to fill the entire 16:10 screen. In this mode, all OSD features are
superimposed on the image. Note that when using a 16:9 input image in this mode, the image will be vertically
stretched by approximately 10%.
The diagrams on the following show how IMD text, timecode, and the audio monitor icon are simultaneously displayed on
the screen in each aspect ratio setting. The white area represents the video image.

15
■Curtain Color
Use this setting to choose the default color displayed on the screen when no video input is present. Available colors are blue,
red,green,white, and black.
■Delete Gamma
Use this function to delete any customized User calibration that has been loaded on to the system via Marshall Electronics’
custom calibration application. Please contact Marshall Electronics for more information.
■Framelock Mode
Framelock is used to designate the selected input as a reference for synchronizing image scaling when using the DLW
monitor. This allows the monitor to use a known-stable input source as a reference-lock to the entire system. In some
conditions, turning OFF the framelock mode will reduce the time needed for image lock.
■2xHD Link Select
When displaying a 2xHD over 3G signal, this function allows you to select between the Link A and Link B channel. When the
signal is not a valid 2xHD signal, this function will do nothing.
■Analog Phase (DVI-Analog or VGA input only)
Adjusts the analog phase value to improve picture quality on DVI-A or VGA Sources. This adjusts the signal phase (not color
phase) of the analog-to-digital conversion.
• 0-31 (value)
■DVI-A CSC Mode (DVI-Analog input only)
Use the DVI-A CSC Mode to accommodate for four different types of colorspace inputs. This setting will only affect your DVI-
A inputs.
• RGB Studio: accommodates digital 480i video using the RGB limited range (16-235) inputs.
• RGB PC: accommodates full range RGB (0-255) inputs.
• YUV 601: accommodates for Rec. 601 SDTV YUV colorspace inputs.
• YUV 709: accommodates for Rec. 709 HDTV YUV colorspace inputs.
The monitor’s default setting is RGB PC.
■DVI-D CSC Mode (DVI-D input only)
Use the DVI-D CSC Mode to accommodate for four different types of colorspace inputs. This setting will only affect your DVI-
D and HDMI inputs.
• RGB Studio: accommodates digital 480i video using the RGB limited range (16-235) inputs.
• RGB PC: accommodates full range RGB (0-255) inputs.
• YUV 601: accommodates for Rec. 601 SDTV YUV colorspace inputs.
• YUV 709: accommodates for Rec. 709 HDTV YUV colorspace inputs.
The monitor’s default setting is RGB PC.

16
■HDMI CSC Auto (HDMI input only, via the DVI-I interface)
The HDMI CSC Auto setting is used to accommodate newer HDMI interfaces that send colorspace signaling in the HDMI data
stream. If this setting is set to On, the monitor will automatically determine which colorspace setting to use. If this setting is set
to Off, or your HDMI signal does not contain colorspace signaling, the DVI-D CSC Mode described above will determine the
colorspace configuration.
