Mind if I ask why? PPI? I'm torn between this LG and the Samsung C27FG70 27" VA 144Hz Quantum dot and really need to make a decision soon. PPI and distance to screen (just under 2 foot) are my concerns over a 34" screen.
24" 1200p, 24" 1080p and 29" UW 1080p is pretty close between them
34" 1080p is around 81.
27" 1080p is around 81
I think 81 may be too low.
If you are looking at 27" I'd get a 1440p at 108ppi, or 32" 91ppi
From pictures I would not get IPS, with the backlight bleed. Also 29" LG UW is only 75hz. To get 144hz, you'd need the 34" 2560x1080 144hz, which is too low ppi (and if it was 95-100ppi then higher res, which means a better GPU is needed)
For desktop 34" 1080p UW is not enough, and for games it may be ok, but that means need some AA. Also whole point of geting bigger screen is more screen estate, if it's the same res as a lower monitor you'll see everything as you will on a smaller monitor, just means the things are bigger. So for games like Company of Heros a big screen , low resolution monitor is a bit stupid.
I'm used to 24" 1920x1200 16:10 so I would want to keep it around that ppi.
Plus whether UW is worth it, I do play some games that support UW
also cost, there's the new 27/32" VA samsung 144hz but you're looking at £600-£650, or the UW 34" about that, or more for 100hz..
I think similar size, similar ppi VA 144hz 125% gamut will be a upgrade over my TN 60hz.
