Right had a bit of time to get used to this MSI MPG 341CQPX QD-OLED 34" ultra-wide monitor, thought I'd give a little bit of feedback as might be others interested in this kind of screen.
I'm coming from a 9 year old Acer Predator X34 100Hz IPS so bear that in mind as it's my reference point. I do a bit of gaming, mostly racing games (Assetto Corsa, ACC, Dirt, rF2) but also some FPS. I also photo/video editing using Photoshop CC and DaVinci Resolve as well as general web browsing.
Updated the firmware as soon as I got it which was easy enough. Overall it's very nice, colours certainly pop - too much to be honest. I'm connected using HDMI to my 4090. Using the "User" setting to ease back the colour temps a bit especially red which in my eyes was far too dominant. In HDR mode (Win+Alt+B) which I use for some games I'm using the "Display P3" setting, which to see seems most natural/accurate. It's easy to adjust the monitor settings with a multi-way button on back of the screen.
240Hz is clearly smoother than 100Hz I was used to in gaming - but I don't feel like it's a MASSIVE difference, maybe that's just me. With all the graphics goodies turned on I can't get near this FPS though in most games, but the freesync/G-sync seems to work well to avoid tearing - although settings vary per game. I have set an FPS cap in Nvidia control panel to 237fps as older games like Assetto Corsa I can max out.
The packaging of the monitor was good, screen itself has a plastic protective film on which was satisfying to remove.
The screen itself is glossy finish and very reflective. On a bright day the reflection/glare is certainly more noticeable than my old IPS screen which had a matt finish. I can see in summer needing to bump the brightness up which is currently set at 50. The sharpness and text clarity is decent and certainly no worse than X34, I can't see the purple fringing people mention. I'm already used to ultra-wide but I remember coming from a 24" 16:9 it was such an improvement, the extra width is great for racing games and also photoshop work as I have tools and actions down each side.
The curve is noticeable but quite subtle - about right I would say.
Compared to my old X34 there is no big power brick, just a normal lead which makes cable management easier.
There is a bit of coil whine when I put my ear up to the back of the screen but not noticeable for me at viewing distance.
There's a black border around the sides and top of screen as mentioned earlier, personally I'd just prefer a thin plastic bezel, would make handling/moving the screen easier. I slide mine around on the desk as I have a steering wheel pedal setup for racing games. I've stuck some cut to size soft felt pads on the bottom of the stand which makes sliding it around easy.
The stand itself is solid but quite bulky - means the screen itself is quite far forward off the wall. Can be a problem with shallow desks. My old X34 was fairly similar in this regard, although the screen on X34 would adjust lower on the stand which I preferred.
Pixel shift takes a bit of getting used to and the panel refresh thing is what it is. Time will tell regarding screen burn in, I'm not going to pussy around too much but have set screensaver and monitor to go into standby when there is inactivity.
Overall I'm happy, but perhaps I could have stayed with my old X34 for longer, that still performs well. There is a 175Hz version of this monitor (MSI MAG 341CQP QD-OLED) which I was considering as it's £200-£250 cheaper. If the panel is the same then that's certainly a better deal. I don't see much difference between 175Hz and 240Hz (probably some people lol at that) and for what you get I think that's a good deal, especially if upgrading from a 24/27" 16:9 or older display.
Maybe this helps someone at some point. cheers
