A small guide for attempting to help U2410 tint issues
As long as the differences are small, you can - to a very minor degree - attempt to correct the tint issues. Switch the screen to custom mode. Go into the "GAIN" setting. If you have a pink/green/blue/whatever tone, whilst viewing a white background, adjust the RGB gain levels. Don't put them down too low or you'll ruin the screens image quality. Try to stay as close to 100 as you can whilst minimizing perceived tint.
Next, go to "SATURATION". Turn down the Red amount to maybe around 40. Again, you don't want to go too low. Then turn down the Magenta a bit too.. maybe 45 or whatever. Use an image like the Lagom.nl Colourbands to help see what you're doing. The effect on the tint issue is minor compared to the "GAIN" setting, but it does have a huge impact on the wide gamut problem of over-saturated reds etc.
In the "HUE" controls set nothing above 52 or below 48, otherwise you'll tend to destroy the picture quality by introducing dithered banding. Say you have a pink tint, perhaps moving the red tones (very) slightly towards a blue hue may help a tiny bit, and the blue towards red. It's also worth noting, depending on your own screen and other settings, the Magenta value here may hold the key for you being able to see square 254 in the Lagom white test. Don't set it below 48 though. I set mine to 49.
Finally, "OFFSET" is good for tweaking greys to remove any colour tinge. It's also THE control you want to use to enable viewing square 1 on the Lagom black level test. Generally you'll need to set the level somewhere around 25 or higher before you'll start to see square 1. Likewise, setting too high will slightly harm your ability to see pattern 254 in the Lagom white test.
Of course, you should also play around with your overall brightness/contrast. If the screen has good uniformity I've found the best settings are usually around 30 brightness / 50 contrast, but tweak to your own tastes. Often turning the brightness up a bit helps the tint issues too..
It's worth noting that Custom mode seems like it can't quite fine tune as well as the Adobe/sRGB mode, for example my reds have a tiny bit more pink than Adobe/sRGB in this mode, and I can't seem to fix it without harming something else. But, by viewing a lot of photos, you can generally tweak something which is pretty satisfying and inhabits a nice middle ground between RGB and Adobe, just purely for visual purposes rather than printing etc. Custom mode also helps avoid the "washed out contrast" effect engaging Adobe or sRGB has, if that bothers you. Tweaking this stuff also seems to help the tint issue, if just a little. The more severe the tint, the less pretty much anything other than a new screen will help.
Use as many images as you can whilst tweaking. EG this page
www.northlight-images.co.uk/downloadable_1/DL_page.html has a couple of good images for tweaking purposes.
If i were to get a colorimeter, will it improve the tinting problem?
