Hey are you facing any difficulty with setting up the display ports? I have an ultragear 39

For me it's just that it doesn't recognise the pc through any inputs :(

I have one and for my limited gamespace it’s doing great. I moved up from a 60hz 34in ultrawide so the 2x framerate was a major plus. Very sharp, great color gamut. The 800mm radius of the monitor is wide enough that the sides feel like they wrap around you.  I get a tiny little flicker on 30 or 60fps menu screens, but it’s normal for OLED screens when you’re running Gsync. Barely noticeable in any case, and in-game that isn’t a factor.

I have a 4k lg b2, oled and 120hz. I also have a a 3440p 39” 240hz oled LG monitor. Cinematic controller games where I’m laying back? The tv. Any multiplayer fps or RTS or any mouse based games or tasks? The ultrawide.

Bought the 1440p version of this monitor and returned it and got the 5k2K all in the last week. The 5K2k is AMAZING!

I have the same 39" and I concur with everything stated here. I wouldn't go bigger than this at this resolution. The text when working is borderline.

This why i don't bother. I'm very satisfied with the 39" 1440p variant with my 5080. I'm so used to everything for a long time now i don't see the negatives at all for work/productivity, 5k2k would ruin it for me.
