Dell U4025QW is the king for office work IMO.

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

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 😅

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.

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.

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.

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

I second this monitor. I've had many similar Dell monitors over the years, from the 38" 1600p ones to these 40" 5k2k ones. I have 2 of these 4025's, one on top of the other and when I'm gaming on PC, I switch the Mac to mirror the screens and I change the input of the bottom monitor to the PC. I keep an eye on my mac on the top screen and either use separate kb/mouse or sometimes I use Synergy although I find it to be a bit buggy. I don't find the response time to be an issue but I also don't play a lot of twitchy fps games. 🤷‍♂️ Currently playing TLOU2 and it's gorgeous on this display.

I have two 4025's one on top of the other... both on my macbook during the day, and I switch over the bottom one to pc for gaming. Playing TLOU2 on it right now and it's gorgeous. I don't really notice any smearing, or if I do it feels like just slight motion blur that most games push on you anyway. 😀

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’m the same scenario right now. My final two options are the Dell U4025QW or the LG 5k2k Oled. How is the text clarity on the LG oled? That’s my once concern along with the lack of kvm

12 months ago

Yes I saw this along with their new video today. Might be better to stick with the dell. But the OLED seems so nice

12 months ago

Yes, also Monitors Unboxed posted new video on the LG 5k2k today. They were saying that the curve is very noticeable and the fact that it is is OLED just isn't made for productivity. I do lots of video editing and I would be worried that the timeline could burn in. As much as I want that OLED panel, the more sensible choice may be the Dell

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).

I love my Dell u4025qw, but partly because of the KVM switch that responds to DDC. Of course, it's only 40 inches and not OLED, so in a few years I'll be looking for a replacement. If the LG 5K2K offerings had KVM, I would be interested.

I use a Dell U4025. I love the screen, size and format as well as the built in KVM. I connect using TB with my Mac and DP with my PC. Since I bought the MM4Pro, I seldom use the PC. Art
