This is really the answer. It checks all your boxes. Not the best gaming monitor but slays in productivity and can be used for some gaming too.

I am running a U4025. I have had it for about a year. LOVE IT. Using with MM M4PRO. I use the KVM for those times I need to boot up my Winbox, which is getting less and less frequently! If there was anything I could change, it would be that there was a little more curve in the screen.

Dell U4025QW. /thread Edit: or the brand new 6K 52” version from them. Edit 2: Never mind. I clearly didn't read.

Lol I'm a genius. I should wait until after 7am to reply to posts 😅 I use the 4025 for work and am eyeing the new 52" as well. I'm currently on my 45" LG personal PC monitor; 52" would be a beast 😅

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.

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.

I have the U4025QW and it works perfectly with my Mac setup

I'm currently using a U4025QW with 140 PPI which is enough to not get blurry text in macOS. Before, I had a AW3821DW with 110 PPI and the blurriness was quite noticeable. Curious how 129 will fare.

Congrats. good choice ! \>I stare at a screen for 12 hours a day I do it 14 h/day, 6d/w. Coding. I bought **U4025QW in Feb 2025.** After one year no regrets so far except one. PPI is high and native 5k is leading tireless. I'm using 3840\*1600 and text is crystal clear. But I still like how in 5k all windows fits.

**UPDATE: THANK YOU TO EVERYONE FOR YOUR HELP I WENT WITH U4025QW** I stare at a screen for 12 hours a day. I mainly do 95% productivity and maybe ocassionally 5% the odd game here and there. For work, I use spreadsheets, powerpoint, figma etc. My current set up: 16inch M4 Pro Macbook Pro. DELL 34 Inch S3425DW I have had this monitor for a few months, here are some of my issues: \- PPI density is too low, I can see pixels and text is pixelated. \- It's a little on the small side for productivity \- Colour is terrible (washed out and also just inaccurate) \- Brightness too low \- MY EYES! Eye strain is definetly the biggest gripe. I have noticed in the last month or so significant eye strain from using the monitor. At this point, the pain this monitor is giving me (mainly on my eyes) is actually starting to effect my eye health. It is becoming difficult to work on so I end up having to move text to my macbook to type, kind of defeating the purpose of the monitor. THEREFORE, I am looking to purchase the best monitor on the market for what I do. Money is genuinley no object here and I will pay whatever it takes to get a monitor that doesn't mess with my eyes, is easy to work on. Requirements: \- Ultrawide (I need this for productivity) \- Bigger than 34inch (my current one is too small) \- Dense PPI (so I am not looking at pixelated text \- Easy on the eyes \- Accurate colours and solid quality, strong brightness \- Compatible with 16inch M4 Pro Macbook Pro. These are the ones I am looking at: [https://www.dell.com/en-uk/shop/dell-ultrasharp-40-curved-thunderbolt-hub-monitor-u4025qw/apd/210-bmdv/monitors-monitor-accessories](https://www.dell.com/en-uk/shop/dell-ultrasharp-40-curved-thunderbolt-hub-monitor-u4025qw/apd/210-bmdv/monitors-monitor-accessories) the U4025QW seems to be a good balance of size and pixel density. However, it is a little old- do I wait for a new version of this to be released? [https://www.dell.com/en-uk/shop/dell-ultrasharp-52-thunderbolt-hub-monitor-u5226kw/apd/210-btfw/monitors-monitor-accessories](https://www.dell.com/en-uk/shop/dell-ultrasharp-52-thunderbolt-hub-monitor-u5226kw/apd/210-btfw/monitors-monitor-accessories) U5226KW - Size is insane, maybe even too big, PPI is lower but I guess it will be futher away. I am only familiar with Dell, I am not sure what other brands produce and if they are better. PLEASE HELP!
