That's how I played through Batman, much better, even w/ the dithering on his cape. FWIW, gaming mode did seem a touch snappier w/ the mouse.Put the U2410 in sRGB mode and let us know if you see accurate color or not.

You can notice the grainy appearance in dark images too. Basically it's there all the time, that test just highlights the problem. How much you notice depends on the individual I guess..It is not very obvious unless the patch is blow up very large on the screen and also when the room is very dark.
The issue is already confirmed by Dell.. There is apparently a new firmware revision in the works to fix the problem. It will require Dell replacing your U2410.And even if Dell fixed this via firmware, it is unknown whether the U2410 firmware is user ugradeable.
Keep in mind each screen is different, and graphics cards can affect things too etc. For saturation I have red 40, green 47, and Magenta 43. For hue you can't really set anything above 52 or below 48 without introducing dithered banding into images, and so the adjustments can only be small ones. Gain and Offset settings are highly dependent on your own U2410. I've used enough U2410's to know that Custom Mode is where it's revealed most clearly that not all U2410 panels are created equal. If you've got a good panel you can leave the gain settings very high (red 99, green 97, blue 100 in my case) and have very good white. Likewise the default Offsets should be ok, although you'll generally want to decrease the green value for more accurate greys. If you have panel with an obvious tint then this won't be the case.What RGBCMY values do you have for Custom mode?
It depends on what you regard as important, since sRGB mode effectively chops off the bottom 5 RGB values and tends to reduce the contrast (how much it does this also depends on your individual screen). A better way to think about Custom Mode is more like that of an Adobe style mode without the dither or wide gamut problems (once you dial down the saturation) and with a bit more contrast. If you're looking for sRGB without the dither then it's not going to provide that. If you demand more than "fairly accurate" colours then you're probably better off using a hardware calibration device in standard mode, as I said.IMO, between the black dithering issue with sRGB, and incorrect color/color temp/gamma of Custom mode, sRGB has the smaller compromise of the two.
Why is there so many problems for such an expensive monitor?.. hmm I think I'll go with a TN panel 1920x1200!

Yes - everyone has this. A firmware update 'may' improve sRGB mode.i've just been trying the srgb mode vs standard looking with some pictures and i notice the image seems darker and detail is lost in dark pieces
anyone notice this too?
i have brightness at 30% and contrast at 50%
Even with these issues, IMO, the U2410 is the better screen..I just got 2x 2408wfp few months ago before U2410 released, wonder if its worth the upgrade since theres issues on tint/black dithering/random sorts
That's not only possible, it's normal. The back light needs some time to warm up to full brightness. This will change with LED back lighting, as it doesn't require the same period to warm up.Anybody notice that when the monitor is power on in the morning that the picture is darker and the whites are also darker in sRGB mode, like if the monitor need to warm up to become it's full capacity. Is that possible?
I'm hoping it's not correct, in terms of only minimizing the issue. Although (having checked) the U2410 uses the LM240WU4-SLB1 panel which, as far as I can tell, is indeed a 10 bit panel as Chartal points out, although it may reach the 10 bit figure through dithering. The fact that the LUT is 12 bit should also help. However, whatever's going on, it's related to the LUT in some way I think.Actually, Dell cannot really fixed the issue via a firmware. Maybe they can improve it, but not fix it.
The Dell U2410 has to perform dithering when sRGB or Adobe RGB modes are selected as it needs to display 256 shades within a "less than 8-bit" color space. It is performing the dithering whether it is dark patches or bright patches.
Well, the lag is also high in standard, multimedia, and custom modes where no dither is present. Although it's curious to me how Game mode, which supposedly bypasses most internal processing to minimize lag, is the mode which allows dynamic contrast. Perhaps that's something related to the panels originally being developed mainly for TV's..This also explains why input lag is higher in sRGB / Adobe RGB modes, as the LCD needs to process the dithering and it takes times to do so.
The cure to this wide gamut problem is to get a 10-bit panel so you still have about 8-bit for reduced sRGB color space.
The Dell U2410 is a 10-bit panel (LG LM240WU4-SLB1) with 12-bit processing (LUT).
I have question, is it possible to sent a 10-bit signal with DisplayPort.
hrm. taken with a ultra-wide lens, about 25" away from the monitor....+85 saturation in lightroom...i see some pink...
how bad is the tinting in your opinions?
edit - using photoshop to +89 saturation = omg...i think i'll have to return this. damnit.
As a LCD with IPS panel, it is considered cheap! Eizo SX2462W is 3 times the price.
I think people who buys IPS LCD are more critical than the average user that is happy with just a TN panel.
It has other ones, like permanent banding with middle gray backgrounds ( see the picture => http://img66.imageshack.us/img66/6729/screenflutterq4lv.gif ) . I have the 2490 and other users can confirm this issue too. For more information, read the last posts of this thread.Why not just buy a refurbished 2490wuxi?Aren't they just a hundred or two more? It'd probably be worth it for a superior monitor without all these headaches.
Menx if you have to turn up the saturation by +85 in LR to see that small amount of tinting, I don't think the monitor should qualify as an RMA unless you actually see this amount of tinting on your own, with YOUR eyes. That's a test pretty much any screen would fail.
Don't look to make defects, or you will never be happy with it.
yea, i'll keep it for now...see if it really bugs me or not during the 20 days..
but why is the tinting so much more pronounced when using photoshop vs LR?

Is there obvious tinting without changing the saturation/color balance of the picture? It may be that LightRoom and Photoshop have different severity of saturation change per step.
Like I said, if you don't see tinting without changing the settings don't worry about it. The green to red tint is only a big deal if you notice it in regular use. Also, different people have different perceptions of color, so someone else may notice it a lot less or more than you when used on a regular basis.
Hehe. That's a moire pattern generated because of the way the camera is focusing on the pixels. It's nothing to do with the screen. As said, boosting saturation is going to show up minor flaws on every screen. In my case the boost simply reinforced what I was seeing with my own eyes. Yours looks like a more mild case of tint.I notice the pink cast in the upper right sometimes....gonna have to give it more time to see if it really bugs me or not. what i'm a little more worried about right now are the slanted vertical lines on the left side of the monitor...what's that about?
Ok, then it is an 8-Bit panel, and it uses A-FRC dithering to achieve 10 bits. This makes it a bit more questionable if they can actually fully "fix" the issues in sRGB/Adobe mode. But it'd be nice if anyone reading this, who has a better understanding about LUTs and implementing colour spaces like sRGB on wide gamut screens, could commentSome info about this panel

The cure to this wide gamut problem is to get a 10-bit panel so you still have about 8-bit for reduced sRGB color space. HP Dreamcolor LCD is such a monitor. But it is an expenisve solution.
The other solution is to use Mac OS X as it has full color management. If we stay in Windows, then it would be better to get a LCD with non-wide gamut panel, so it will not need to do any dithering.
Just a remark. I understand that the dithering has to be performed because the wide gamut panel doesn't have 8 bit per channel in sRGB mode (some bits are in the wider gamut).
If the panel is indeed 8 bit per channel, there is no way it can display sRGB correctly. Meaning that, even in a perfectly color managed environment, the panel still lacks the necessary bits to display sRGB correctly. So if I am not mistaking, your suggestion to use Mac OS X won't solve the issue. Every piece of software would need to apply a "trick", such as dithering.
This issue is also related to banding being slightly more prominent on a wide gamut screen, than on a sRGB-panel.
The latest info on this panel is that it is 8-bit + A-FRC so it can mimic a 10-bit panel via dithering. This is the same panel used by Eizo CG243W and SX2462W, both claim to be able to display 10-bit color via Display Port.

yea, but the ACD is also $900 before tax.I went to an Apple store and looked at their LCDs. Unfortunately, they don't have the LED Cinema Display, so I looked at the LCD on the Alu 24" iMac.
Upon looking at the Lagom gradient page, it is extremely smooth. Virtually no banding at all.
Now I'm looking at my U2410. In sRGB mode, there is noticeable banding, but not severe. Even in Standard mode, some banding is still noticeable. It is definitely not as smooth compared to the LCD on 24" iMac
Also, there is no green/pink tint on the iMac LCD.
I think I'm going to return the U2140 for a refund...

I wonder how the sRGB mode is in the Eizos.
