Thank you for the comment on the curve. I swear to god half the forum won't shut up about it. When actually using it, I don't even think about it. It sits next to my 2500r Dell I don't even notice switching back and forth really.

I run that for gaming and the Dell for work. I don't wanna mess with OLED for my all day work monitor.

Are you truly limited to 34"? If not, grab a Dell U4025QW and call it a day.

My 4025 works great in a well lit garage office just on auto mode.

Same. I use it for work. The new 52" 6k monitor looks tempting though 🙃

I played COD on mine when my OLED was down and it seemed fine. Not sure what all the fuss is about.

Great points. The fact that anyone would pretend 140ppi is some how not anything other than awesome is funny.

Then the Dell is for you. Grab a black Friday sale and stack with Rakuten.

LG for sure. IPS black, 144hz, debt brightness. I have the Dell U4025QW but sounds like you don't want 21:9. You can also check out the new Dell 52" 6K UW beast.

Was in the same boat. I had the 1440p 45" and was debating which one. I actually have a 40" 5k2k Dell for size comparison for work and I think losing the size and curvature would be a downgrade for me gaming wise, so I went with the 45GX950A.

The 39/40" LG and Dell 5k2k 21:9s are solid for productivity. On my Mac I use the older LG at 3840 x 1620 HiDPI resolution. It gives me 3 full columns for apps/windows. ETA: LG just started taking pre-orders for their 39" 5k2k OLED. Remains to be seen how bad the text fringing will be as no one has one IRL to review quite yet. Some OLEDs are bad for this. Others not so bad. We'll have to see for this one.

I'd definitely get the 39/40" Dell or LG 5k2k. 3 columns at a sufficiently high DPI that they work well.

Same. Also have the 4090 and the 5k2k and it works great

My 4090 in most games at acceptable settings are still between 90-100fps on my Dell 5k2k. 5k2k 240hz is a waaayyyssss off.

Dell 4025QW and it’s not even close. My M3 Pro MacBook Pro runs it at 120hz but can’t do a second monitor *and* 120hz drops to 60hz. From what I understand M4 Pro/Max doesn’t have this issue.

I used Samsung 49” for productivity and hated the low vertical pixel count. I use the 40” Dell 5k2k 120hz — it’s fantastic.

Dell U4025Q would be your best choice if budget is not a problem. There is a newer 52" one too. For a cheaper VA option, the G75F is a 40" 5k2k monitor ideal for office work. Been using mine for last 2 months with a Mac.

You're not crazy, the way people talk about OLED is very over the top. IPS are certainly useful for productivity. It seems for ***some*** folks OLED can be good for productivity, but it's not universal. Nothing wrong with you, it's just that the tradeoffs are not right for you. That said, there are two 40" 5k2k IPS ultrawides you might want to look at. Both use the same panel from LG * LG 40U990A-W (just released) * Dell U4025QW ([rtings link](https://www.rtings.com/monitor/reviews/dell/u4025qw)) I'm in a similar place where I have a 38" LG ultrawide (looks like same panel as your AW) and I love it. But i'd like to bump up a bit in size and resolution. However the main caveat with the above two monitors is the response time is somewhat poor. This could cause smearing in games. Mostly seems like it would not be super noticeable unless you are into competitive first person shooters. But it's a downside and it's one thing holding me back a bit. My current monitor has a 1ms gtg (advertised, about 5-8ms real). While the above two monitors have an 8ms gtg (advertised, and 15-25ms real world) I am holding out hope things will improve over the next few years but as of now I am in the exact same boat. I'd love an upgrade, but it just seems like every upgrade has at least one area where it would be a downgrade. This 38" LG panel was great in all the right places. It may not have silky blacks, but it's very good in all the places that matter to me. edit: potentially useful video comparison some guy did https://www.youtube.com/watch?v=TXvANNU8oD8
