The u2412m is worth it over the pa238q for multi-monitor setups both in landscape and in potrait. In landscape you'll have a significantly larger viewable area and in portrait you won't be limited to 1080 wide per monitor (which would cause more issues than the 1200 wide of the u2412m), as well as having a more immersive aspect ratio. They are both the same input lag / ghosting wise. The u2412m also has decent QC and you don't have to worry about receiving a bad unit as much as you would with the 850. (Same with the PA238q but you referenced to already know that)
Thanks for the response.
Backlight bleed is a concern but it doesn't bother me that much in the grand scheme of things, I'm more concerned about input lag and ghosting. U2412M would have been my first choice and it's perfect on paper except the suspect ghosting and input lag. Some people say it's great and not to worry while some people and sites say it's awful. TFT has a great review on it but still shows the PA238Q being far better and same with the S24A850DWK because of their less agressive settings (also the U2412Ms settings reset when turned off). I just don't know who to trust or if I'm reading into it too much.
PA238Q seems the guaranteed performance winner but is the 16:9 ratio. Did the maths and the 16:9 ratio is 2.5inchs narrower and .5inch taller in screen space plus bezels. S24A850DWK despite the backlight bleed seems better than the U2412M in every area especially the less agressive AG coating except the stand is really wide and with the bezel removed won't align properly I don't think so it leaves the U2412M again as the best choice.
Is the input lag and ghosting really a non issue even for fast paced FPS? Because it seems the best choice. I'm thinking of getting one and trying it and then commiting to the other two for surround but still don't know which of the three to choose.
