I have my 800r for gaming on the same desk as my 2500r. Have never wanted to bend either. If anything, I'd want a bigger curve on the 2500r Dell 😅

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.

Dell U4025QW is the king for office work IMO.

Dell is better. 120hz refresh rate to start. Just Google it.

Dell U4025QW + small vertical monitor on the side.

It's the king of office work with all the connectivity. 5k2k panel. 120hz. IPS Black. Slight curve.

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

The absolute drama and overreacting in the comments is hilarious. For gaming, the 45" 1440p is excellent. That's what this thing is made for. For text clarity or working, it's absolutely not good. OP - go for the 5k2k, or a Dell U4025QW if you're mostly working.

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 replied on the main thread already. Grab a Dell U4025QW or LG's variant and stop trying to make an 800r monitor fit your needs. If the voice of customer eventually shows that less than 800r for the *target audience* is better, they'll change.

Dude now you're just being stubborn, rude, and pretentious. I just suggested the Dell which is high FPS and great for the games you said you currently play. It has a mild curve and is excellent for productivity too. I also explained why manufacturers have made such an aggressive curve. It's because it's what their **target market** wants. They're making high end gaming monitors. They don't cater to smaller use cases who want both. And I never said I was against more options. You're asserting that. I'm telling you that's not how product development works. An extra SKU is tens or hundreds of millions in extra cost, inventory, and resources. You clearly don't care what anyone is saying to you, so just continue to talk at everyone.

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.

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.

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.

Ive used both, have also had the LG 45 5K2K and Samsung 57. Currently have the Samsung 40 5k2k. The LG text issue makes it pretty awful for productivity. The vertical space is essential, so Id recommend the Samsung 40, plus I believe it's on sale

Dell's 5K2K has built-in KVM, that's the edge I'd give it over LG. Both use LG panels.

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.

I was lucky and found the Dell U4025QW for £1,050 in the UK refurbished on the Dell UK Outlet website (on 25th January). It was the only one in stock and I haven't seen it in stock on there since, but it's worth keeping a lookout there (if there is a Dell Outlet store in your region).
