After two exchanges my third panel is free of defects. All three of my panels had pretty severe IPS glow, so I guess this is just inevitable with this monitor.
I have a U2410 at work, and overall I think the U2410 is much better than the U2412M. The U2410 seems to have much less IPS glow.
It's stuck bright. It's pretty noticeable on an all-black background, though not very noticeable in other scenarios.
When I buy a new product I expect it to be free of defects. In the case of stuck pixels, Dell definitely agrees with me since they have an explicit stuck-pixel exchange policy.
Ugh. I received my replacement from Dell today. There's almost no backlight bleed, but this unit has a stuck pixel :(. From my sample size of 2, the quality control on these monitors seems really bad. I'm running a tool that alternates colors to try to fix the stuck pixel, but if this...
The problem hasn't gotten any better so I called Dell for an exchange. The rep was friendly but it took about 20 minutes on the phone to get the exchange processed.
By coincidence I recently got two U2410s and work at they're both perfect. I like the styling of the U2410 better but it's not...
The upper-right corner looks worse in the picture than in person. It's not noticable in typical use. But the lower-right is horrible. I can notice it when playing full-screen games in normal room lighting.
I just received a U2412M today and the backlight bleed is pretty bad:
I'm going to give it a few days to break in, but it's probably going back. Are other models like the HP ZR24W less prone to this problem? I'm trying to decide if I should exchange or get a refund.
