Insane refresh rate with amazing image quality. I have it mounted on an arm connected to a PS5 and two laptops and it work perfect in all 3. Lots of ports to connect, great for movies, work, lots of modes and Ai vision. And it looks elegant and on my desk. If I get another monitor I’ll be going for another of these. It can be adjusted to any use you give it to. ... show more

    • Great monitor rendered useless by a single incredibly obstructive "feature"
Style: MAG 321UPX QD-OLED 32 Inch 3840 x 2160 (...
Can't recommend this monitor in the slightest, despite incredible picture quality and color, because for some insane reason MSI decided that a "giant blue 'OLED care' text box covering the entire center of your screen that can't be cancelled or dismissed that pops up without warning" is a good feature to have on a "gaming" monitor. Fiddling with settings to alter the OLED care feature doesn't do anything to fix this. A monitor that forces itself to take a nap for 10 minutes in the middle of a gaming session without warning (besides the mentioned giant blue text box which also can't be removed) at least once per day is the most absurdly useless thing... I don't know whose idea it was to add this "feature" but it ruins the entire product. ... show more

Review Image by Christopher Focht
Coming from using VA monitors, but OLED TVs I had high hopes for this MSI OLED. First off this is a glossy monitor though the anti-glare coating is better than I expected very little reflected light in a standard lit room. It won't handle a lot of a direct sunlight well though so keep that in mind when ordering. 240hz seemed overkill at first but it's pretty noticeable compared to the 165hz on many of the cheaper OLED panels. It's plenty fast for FPS gaming but you'd probably be better off with a 27" 400hz+ monitor for that. This one really shines with Media and immersive single player games where the visuals trump refresh rate. ... show more

Style: MAG 321UPX QD-OLED 32 Inch 3840 x 2160 (...
This monitor has been exactly what I was looking for and is so far and away a better experience than my previous IPS monitor. In my eyes, this is the model to get if you are in the US and looking for an OLED that isn't completely absurd in price, i.e., those that cost $1200+. The higher framerate for games that I am able to reach while using 4k is only slightly noticeable from 165hz but it is noticeable. I would say that the near-instant response times from OLED are quite noticeable however and combined with the clarity that 4k provides in conjunction with the perfect contrast, the monitor plays MUCH BETTER. In single player games especially, the benefits of OLED are just so immersive and adds a new layer to games. Scenes that were once washed out, grey/blue tinged, and overly bright in general are now properly darkened and lit correctly. It really is something that needs to be seen in person in direct comparison to non-OLED tech. It is markedly different and just flat out fun. The only difference between this and the MPGURX is that the URX carries 90W power for charging stuff at your desk, while this one is at 15W. I have been using this plug for charging my phone at my desk and it is a really nice addition. I can see where I would enjoy the 90W version with the MPGURX but at the time, that model was out of stock and was about $100 more. The controls for picture quality and the settings you are quickly able to change to your liking are really easy to use. The burn-in protection features are really nice as well and not obstructive really at all. I have taskbar detection on, static icon on, pixel shift on, and run panel protect every 4-6 hours and have had nothing as far as burn-in goes. ... show more

    • Fantastic image quality, sleek design and smooth performance

This monitor blew me away with its picture quality—deep blacks and colors thanks to the QD-OLED panel, you can truly tell the difference from my 27" LG Odyssey G7 that I had before upgrading. Gaming feels super smooth while using 1440p@120hz on this massive screen. The build is solid and sturdy, the setup was simple, and it has all the ports I need. I also like how it came with a full report on it's QA testing and it's results for color accuracy, color gamut and gamma curve. The price was a little more than I originally planned to spend, but so far it's been worth every penny. ... show more
