1.1 Product description
190X6 is the 6th generation of Hudson 19 TFT Flat Panel Display
Monitor. The monitor featured with both DVI-D and analog signal
Input interface, and modularized as a display unit with embedded
Universal AC power supplies inside monitor main body. The power
Button and display control buttons (tact switch type) are on the front
And the right-hand side of the monitor. The monitor shall support an
Internal scaler to automatically enable the monitor to display lower
Resolution video modes into 1280 x 1024 full screen display. The
Image can be adjusted through OSD control board. These adjustments
Can be stored on a board memory including 34 pre-set modes and 16
factory pre-set modes.

On Screen Display
On-Screen Display (OSD)is a feature in all Philips LCDmonitors.It allowsanenduser to adjust screen performance
or select functions ofthemonitors directly throughan on-screen instruction window. A user friendly on screen display

front bezel ofthemonitor to move thecursor,to confirmthe
choice or change,andto adjust/select thechange
Note:sRGBis a standardfor ensuring correct exchange ofcolors between different devices (e.g.digital cameras,
monitors,printers,scanners,etc.)
Usingastandardunifiedcolor space,sRGBwill help represent pictures taken byansRGBcompatible device correctly
on yoursRGBenabledPhilips monitors.Inthat way,the colors are calibratedandyoucan rely on the correctness of
thecolorsshownonyour screen.
Important withtheuse ofsRGBis that thebrightness andcontrast ofyourmonitor is fixedtoapredefinedsetting as
well as the color gamut.Therefore it is important to select thesRGBsetting in themonitor'sOSD.
Todoso,open theOSDbypressingtheOKbuttononthesideofyourmonitor.Move thedownbuttontogotoColor
andpress OKagain.Use therightbuttontogotosRGB. Then move thedownbutton andpress OKagain to exit the
OSD.
After this,please do not change thebrightness or contrast setting ofyourmonitor.Ifyouchange either ofthese,the

Philips' Flat Panel Monitors Pixel Defect Policy
Pixels and Subpixels
Types of Pixel Defects
Philips strives to deliver the highest quality products. We use some of
the industry's most advanced manufacturing processes and practice
stringent quality control. However, pixel or subpixel defects on the TFT
LCD panels used in flat panel monitors are sometimes unavoidable.
No manufacturer can guarantee that all panels will be free from pixel
defects, but Philips guarantees that any monitor with an unacceptable
number of defects will be repaired or replaced under warranty.
This notice explains the different types of pixel defects and defines
acceptable defect levels for each type. In order to qualify for repair or
replacement under warranty, the number of pixel defects on a TFT LCD
panel must exceed these acceptable levels.
For example, no more than 0.0004% of the subpixels on a 15" XGA
monitor may be defective. Furthermore, Philips sets even higher quality
standards for certain types or combinations of pixel defects that are
more noticeable than others. This policy is valid worldwide .
A pixel, or picture element, is composed of three subpixels in the
primary colors of red, green and blue. Many pixels together form an
image. When all subpixels of a pixel are lit, the three colored subpixels
together appear as a single white pixel. When all are dark, the three
colored subpixels together appear as a single black pixel.
Other combinations of lit and dark subpixels appear as single pixels of
other colors.
Pixel and subpixel defects appear on the screen in different ways.
There are two categories of pixel defects and several types of subpixel
defects within each category.
Bright Dot Defects Bright dot defects appear as pixels or subpixels that
are always lit or "on".
These are the types of bright dot defects:
One lit red, green or blue subpixel
Two adjacent lit subpixels:
- Red + Blue = Purple
-Red+Green=Yellow
- Green + Blue = Cyan (Light Blue)
Three adjacent lit subpixels
(one white pixel)
Black Dot Defects
Proximity of Pixel Defects
Pixel Defect Tolerances
Black dot defects appear as pixels or subpixels that are always dark or
"off".
These are the types of black dot defects:
One dark subpixel
Two or three adjacent dark subpixels
Because pixel and subpixels defects of the same type that are nearby
one another may be more noticeable, Philips also specifies tolerances
for the proximity of pixel defects.
In order to qualify for repair or replacement due to pixel defects during
the warranty period, a TFT LCD panel in a Philips flat panel monitor
must have pixel or subpixel defects exceeding the tolerances listed in
the following tables.
BRIGHT DOT DEFECTS ACCEPTABLELEVEL
