What does a A-TW polarizer do?
Every monitor is indivdiually calibrated. Dell probably didn't do a good enough job on his. Mine is perfect, with no deltaE readings over 2. Guess i have been lucky, since Dell promises no less than an average of less than 5 deltaE.
Yes, you have to go into menu.
Thanx for the info. My 2001FP doesn't seem to have a glow, but does it have this type of polarizer? 8 year old monitor?
That has nothing to do with the A-TW polarizer. The first generation 24" and 25.5" H-IPS panels always had the non-grainy coating, regardless of the A-TW polarizer. Newer panels seem to have gone back to the grainy coating.10e said:1) Removes the "graininess" or sparkle associated with LG panels typical anti-glare
The 25.5" H-IPS panel used in the NEC LCD2690WUXi and the Planar PX2611W gave me the most trouble with whites, which had a tendency to be yellowish green. I don't think the A-TW polarizer really improves anything there. The NEC can achieve better results with ColorComp + better calibration through the internal LUT.10e said:3) Seems to improve the quality of whites. None of my other monitors no matter how accurately calibrated can get as "tint free" white as my LCD2690 (with the A-TW polarizer). The only one that is close is my 5 year old Dell 2005FPW, strangely enough.
The white glow started with later AS-IPS panels. Older S-IPS panels had an orange glow at slight angles and purple at extreme angles, which I found it just as bad as the white glow. I don't know why the color changed. Maybe different filters are being used now.10e said:Since it should be an S-IPS (Super IPS) panel, you will have a slightly less noticeable violet or purple mirror-like glow on blacks when viewed from certain angles. My older Dell 2005FPW is the same. The white glow is characteristic of H-IPS (horizontal IPS) and eIPS ("efficient" IPS)

Can't comment on the DS 25.5" panels, because up here in Canada all I found was crickets when trying to get 'em. Surprising that LG had panels with less of this without the A-TW polarizer. Have you seen the LP2475W and how does it compare?The HP DreamColor LP2480zx has both the A-TW polarizer and the grainy coating, while the original Planar PX2611W had neither. Also, I saw both versions of the DoubleSight DS-263N, with and without the A-TW polarizer, and both had the non-grainy coating.
I would say that my LCD2690WUXI-BK has this problem with the sRGB preset, even with the newer versions of SVII which are supposed to do some calibration of sRGB preset, but out of the box before I received my SVII kit, the native and programmable modes had very good whites that are less yellow/green than my 2709W and 2209WA even after calibration. It might be more due to firmware/hardware revision, as I believe I received a later one than what you had, as I got it in April 2008. Or it may also have to do with how it was calibrated from the factory.The 25.5" H-IPS panel used in the NEC LCD2690WUXi and the Planar PX2611W gave me the most trouble with whites, which had a tendency to be yellowish green.

Just an FYI...
Over at Engadget (or however you spell that), site, news of LG about to come out w/ several 'gaming' monitors...
I'm totally excited about more 16:9 TN panels.
The U2410 is unreleased, untested, and unpriced (for the US), so any comparison or decision at this point would just be a guess. It sounds very promising, but we will have to wait and see. There is also the NEC 23" IPS that's already being priced < $400 on several sites, and is 1080p instead of 1920x1200, but that's untested as well - it could be another option.
can anyone confirm that the U2410 does not have the grainy anti-glare coating like the 2007WFP has?
Yes, the monitor has a grainy/ sparkling coating. At first i thought this was posterization/ banding looking at pictures, but i found out while playing that it actually was the coating that produced the grainy effect. It's not a problem really, because you only notice it while looking close at the screen.
Thanx so much for comment
Now does anyone know if the Philips 240PW9ES suffers from the same coating ?
Min 0 frames (0ms). Average 0.56 frames (9.4ms), Peak 1.33 frames (or 22ms)
Alright, so I guess it's not too far fetched to say that it's way under 1 frame of lag using game mode and using sRGB emulation the input lag is on par with the HP
Kicking in game mode has a noticeable effect, reducing input lag considerably from the sRGB mode. The side effect though is oversaturated, wide-gamut colours, with greens and reds once again ramping up.
Conclusion
Our only negative point on the screen is that once again Dell has inset the panel itself, so the image partly reflects on the bezel. You soon get used to it though, and with this screen sitting on your desk the vast array of positives soon outweigh the single negative. The only way to get better quality than the Dell UltraSharp U2410 is to spend a lot more money if you need 24-inch, are on a budget but still need great quality images, we can wholeheartedly recommend this screen.
Before I go over this whole thread is this basically a Dell 2209WA except 24"? Price? ETA on when it hits the States?
Where have you folks found these specs? And, if that's accurate, then this could be an IPS that will be fine for 'FPS' gaming?
Looking at the uniformity test at digitalversus, i can see that they also have white glow coming from all the sides when looking straight at the screen. Maybe this is a trait of every Dell U2410 monitor?

So when you look straight at the screen, you will have glow like this;
But as soon as you move your head down a little, the glow gets more pronounced in the upper parts;
About the different presets, i can definetely see the extra saturation in every other preset than sRGB. To be honest, every other preset than sRGB look like crap. Colors and hue look very wrong. sRGB preset looks perfect, i love it.
My own testing showed 0.5frames (~8ms) of lag in game mode, and 1.5 frames (~23ms) in sRGB mode, so it seems to be on par with what others are getting. You can notice the lag a little in sRGB, but it is far from annoying. Iv'e owned the NEC 2690wuxi and 2490wuxi, and they both had annoying lag.
