Quote from ai42 :
I think it's far easier to understand in terms of number of pixels at a given resolution. Given GPU horsepower X which is roughly number of pixels per second, it mostly scales to resolution especially above 5M pixels.

5k2k = 11M pixels
4k = 8.3M pixels
3840x1600 = 6.1M pixels (resolution of LG 38" nano-ips)
WQHD = 5M pixels
QHD = 3.7M pixels

My big issues with these OLED's is that they haven't gotten to the PPI for real productivity work, great for gaming but kind of not good for productivity. LG made nano-ips 38" monitors at 3840x1600 (6.1M pixels). Why isn't this 39" at least at that resolution? Plus 6.1M pixels is marginally more GPU horsepower needed compared to the bigger jumps to 4k, or 5k2k. The other compelling monitor in a similar size / resolution is Samsung's new 37" 4k offerings, >40" 4k is kind of too unwieldy on a desk given the vertical height. If you do any webcam and do conference calls, people will be looking at your bald spot. But 37" is a nice size, try it into one of the display comparison tools.

That 38" is 16:9 where as this is 21:9

edit

i am wrong and i didn't know that resolution existed, thank you for informing me

Is it really just end of quarter sales to boost numbers. Should I only by quarterly ?

I'm a lawyer and use it every day for reading and studying. I use dark light settings and haven't had one issue.

Had a feeling the text clarity issues are overblown.

Kids these days don't understand the struggles of early tn panels and what was accepted as "top of the line" 20 years ago.
they're way overblown. I have this monitor and a samsung 34" oled, and I can't tell a difference in the density just looking at it. You have to nitpick to see it.
I think reviewers had to have something negative to say and this was the best they could come up with. Literally every review on this monitor complains about that. In gaming and every day use the density is not noticeable, even when side by side with other monitors.
my only gripe about this one is the brightness, it doesn't get bright enough imo, not like that samsung does. Still good enough, but could be better.
what I do love is the curve though. It really reduces the amount of real estate your eyes have to travel playing games, it seems like everything is front and center vs lower curved monitors.
