Re: U2410 Green/Pink Failure Analysis

DELL-Chris M:
(1) All received captures were tested and are within manufacturer specifications for color gradation.
(2) The Color Calibration Report results are generated by testing the center of the monitor, not the left and right sides.
Since when do people only look at the middle of a screen? A screen must be considered as a whole, because that's what people actually look at, not a small section in the middle!
As for LG, their response isn't a surprise. The green/pink tint issue isn't really a major concern when a panel is used for TV's (their primary business). However Dells customers aren't only TV viewers - they are computer users - people who regularly look at white and grey backgrounds on applications and webpages, and here these tint issues can be a major distraction. I'd suggest that Dell needs to demand a higher standard from LG when it comes to the supply of panels for the purpose of being used on premium computer screens.
(3) There will not be a firmware written for Green/Pink color gradation.
(4) To alleviate this -
* Open the OSD (On Screen Display)
* Go to Color Settings
* Go to Preset Modes and change it to sRGB
Switching to sRGB MODE alleviates NOTHING. To even suggest this is outright misinformation, there is NO other word for it. Whoever at Dell suggested you put that out there ought to be ashamed of themselves. All sRGB mode might do is limit the colour gamut of the screen - it has no real impact on tint issues, as anyone who is reporting this issue will be happy to tell you I'm sure..
Also, Dell CAN fix this issue.. What Dell need to do is add controls to independently adjust different areas of the screen so that they match. Several of your competitors, such as NEC (with Colorcomp) and Eizo (with "DUE") already do this. Granted, these panels tend to be more expensive than Dells, but Dell need to seriously consider a way of adding these sorts of controls unless they're actually saying they don't care about these tint issues - In which case perhaps they'd like to tell people why they should spend much more for a U2410 when many of Dells cheaper panels do not suffer from these tint issues?
(5) We are still awaiting the firmware fix for the Graininess in sRGB and Adobe Modes
And now anyone, who has a panel which has no major tint, must risk submitting their screen for a replacement which may come back with severe tint issues which Dell will inform them is "within spec"? Nice..
I honestly thought Dell was better than this..
