I had a 49” with 1440p that I got explicitly for productivity and I returned it after a week of use. The text clarity on that screen wasn’t the best and it was hurting my eyes and giving me a headache. I decided to try a 40” 5K2K screen and it’s a much better experience. The text clarity and 120hz refresh rate is a significant improvement. I highly recommend 5K2K resolution over anything for productivity. If you really want the screen real estate and don’t mind the 1440p, get the 49”. You can also consider the Samsung 59” if you are looking for 2160p resolution. For me, 40” 5k2k is the sweet spot.
I had the Samsung Viewfinity S9 which isn’t the best 49” screen they sell. I got it because of the USB-C power delivery. I ultimately decided that I didn’t want to keep it due to the eye strain and headaches I was getting when using the screen. I now have the Dell UltraSharp U4025QW 40” and I am happy with this screen.
I've been using this Samsung 49" LS49C954UANXZA for the last year with my work MacBook + my personal Windows machine, the kvm is a lifesaver. It lets me switch off work at the end of the day when needed so I can work on side projects and learn new skills.
Well, I have an ultrawide, albeit a viewfinity office monitor, so not a gaming one, and it feels a little weird in some games. I have a dual monitor setup with Samsung Odyssey g5 1440p 180hz monitors though, 32" primary, 27" ,portrait orientation, secondary. They are IPS, but i think they look great. Personally, feel like 32" is a large size, and going beyond that starts to feel more like a tv than monitor. I'd say 27" if you play more competitive online games though, less screen to watch for enemies. I like my 32" though, little bigger and better for story gaming than the smaller screens, as i am sitting back more casually.
Once you go ultrawide, you will never go back. I'm on a 49" 5120 x 1440 120hz ultrawide as a daily driver. Ultrawide is a totally different experience, so much more scree real estate.
For a single? 49” 1000R, and add an extension rod to your real base so you can get all the fov.
I've had a 1000R 49" for awhile now and while it's curve does fell overly aggressive for me during certain tasks it's amazingly immersive for gaming. No headaches. Prescription glasses and contacts. 800R it begins to get more difficult for me to do designs that require straight lines though. I think I've finally found the sweet spot at 40" 5k2k and 1000R though. Curved enough to be emersive but not so curved to be difficult to work on. A 39" 1500R screen might be the best place for you to start and see if you're brain adapts. It could be your just overly sensitive to curves.
