Our community has rated this post as helpful. If you agree, why not thank jefflins

also 10% back on the Prime cc. Note pixel density may not be the best for work/programming use case.

For gaming, you'll lose mild clarity for huge fps boost..i think it's a good tradeoff

i have this. if you're primarily looking for gaming use, and a big display is your thing.... this is amazing. but as others have said the lower pixel density can be noticable. if you care about that I'd recommend stepping down to the 34"

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.

Like $650 about 6 weeks back. Was alive for a few days, completely sold out. Essentially the same panel

why not just get a smaller 3440 monitor then. you'll GAIN mild clarity AND a huge discount.

Nah, i used a 32" 1440p monitor for ten years and it's fine. Clarity issues are overblown. 40" 3440x1440 is the same ppi. Not to mention 24" 1080p is also the same ppi, the most used size/resolution combination in the world.

Have I mentioned the performance overhead for going to 4k? A 5090 will feel like it has extra legs at 1440p, it will obliterate all games at high frame rates. If I was going to upgrade, it would be 5k2k, and I'm not going from a 100fps experience on my 9070xt at 1440p to a 60fps experience at 5k2k with a 5090.

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. And if AI doesn't take over the world by then, 5k2k is going to be the next product jump, and the justification to buy a 7090 in 3 or 4 years.
