MSI MAG 321CUP QD-OLED 32 Inch UHD Curved Gaming Monitor - 1700R, 3840 x 2160 Quantum Dot OLED Panel, 165Hz / 0.03ms, 99% DCI-P3, ΔE≤2, DisplayHDR True Black 400, DP 1.4a, HDMI 2.1, USB Type-C

-= The good =-Coming from a QLED panel the monitor is a great improvement. I like the dark blacks so much, and the viewing angles are perfect. It also looks significantly brighter, and HDR quality is great.The M1 MacBook Air that I use for work only supports a single external display, so an ultrawide is a great replacement for a traditional couple of monitors. It is great to have an opportunity to stack a few windows horizontally for productivity, and to use the full display area when having fun.I was looking for a good KVM implementation as I use both a Mac, and a PC. For my purposes the KVM here ticks all the boxes. I'll explain how I use the KVM, because when I did my research I couldn't find a clear answer if my intended workflow was supported. I wanted to have both computers connected at the same time, and switch between them with a keyboard shortcut.For the Macbook I can finally use a single USB4 cable (not included in the box) for sending the video signal to the monitor, connecting keyboard and mouse, and charging the laptop at the same time (you need to enable power delivery in the OSD menu). My desktop is so much cleaner now, and I don't need a separate USB-C hub. The official apple charger suffered from a slight coil whine, which was a bit annoying. This monitor is silent, and its integrated usb hub doesn't have any coil whine, which is a great quality of life improvement.The PC is connected via a USB type B connection plus an (included) HDMI cable. The USB-B is for passing the keyboard and mouse signal (attached to the monitor) to the PC. And HDMI is used for the video signal. Displayport is also supported, but there is no Displayport cable in the box, and it seems that HDMI port here is actually more capable. It has higher bandwidth, and so supports the full 5120x1440x144Hz connection without using compression. On the other hand, the Displayport connection relies on compression (DSC). This could be important for Nvidia users because some functionality provided by Nvidia GPUs is only available over an uncompressed connection.Now the KVM switching part. When I want to switch PC --> Mac (switch both video signal and keyboard + mouse), I can use the MSI Gaming Intelligence App. I assigned a hotkey combination to change the input source to USB-C. When I press it, the monitor switches connection (which takes a couple of seconds), and I get to the MacOS desktop. Switching the other way is a bit more complicated, because MSI doesn't seem to have any MacOS apps. I installed an app that's called BetterDisplay. It can control lots of external display settings (including brightness, volume for attached audio devices etc) from your Mac without using the monitor OSD. What's important, it can send a signal to the monitor to switch the input source to the one of your liking (it's called DDC input source in the app). For me it works flawlessly.For some people it's probably important to be able to switch just the keyboard + mouse without the video. I believe it is possible (there is an option to switch KVM instead of the input source), but I didn't check that.-= The bad =-There were a couple of times while setting up the monitor, when I had to search online for a solution. But once set up it's a smooth journey.One thing is that when first connected, the monitor pretends to be an external drive to automatically install the software. If you are a Windows user, you're lucky. It's going to proceed with the installation, and then it seems like some flag is switched in the monitor firmware, and it stops injecting this external drive. But for Mac users the software can't be installed (there is no app for Mac at the moment). So the NO NAME external drive keeps popping up (once ejected, it's being connected again right away - very annoying!). The solution for me was to connect a Windows PC, install the app, and then the drive disappeared for good (on all computers). You'll need just one successful installation while the monitor is connected. If you don't have a Windows PC, I heard that a virtual windows machine (like in Parallels) could help.Another thing was that the Gaming Intelligence App was showing a message that it can't find the USB-B connection. Which was strange because keyboard and mouse were using this connection and were working absolutely fine. Fortunately, power cycling the monitor helped (turning off, and pulling the plug from the socket).-= Some final words =-Overall, I find the monitor great, it has a beautiful panel. And while there were some issues when setting it up on a Mac, it definitely wasn't the worst experience.Ah, almost forgot - set the pixel protect notice to 16 hours. It will be running the panel protection while the monitor is asleep, and you won't notice. Good stuff!

Truly a wonderful piece of technology. I got it on sale for a very reasonable price, and so far have been enjoying it greatly. The colours are deep and the blacks are like ink. The stand for the monitor is robust, though it does take up a large amount of space, it's currently overlapping onto my mouse mat, however due to the ease of being able to move the monitor around to a position thats comfortable, this has been no problem. I love the fact that I can turn and angle the monitor with a gentle push, it feels smooth and stable no matter what position it's in. The visual clarity of the monitor is really great, and i'm very happy with my purchase.

This was a replacement for a BenQ 27inch monitor I purchased in 2016 which I must say was an excellent monitor and was used almost every day, it finally started to flicker, I did a bit of research and this MSI monitor kept being recommended in lots of reviews.I did have an OLED tv a few years ago and it was replaced under warranty because of the amount of screen burn, so I was reluctant to purchase another OLED panel.After reading many reviews and recommendations i decided to purchase it as it comes with a 3 year screen burn protection warranty and has comprehensive set of panel protection software built in.I must say the picture quality is outstanding with loads of preset options built in for various uses of the monitor ie gaming, video editing ect.It has good height and swivel adjustment positions and has improved my gaming and video editing enjoyment immensely .At this price point I think it should have had some in built speakers which would have been useful for certain applications but for my main uses which is gaming and video editing I use my surround sound system or headphones so it’s not to bid an omission.If your after a monitor with a high refresh rate and low response time and outstanding picture quality this is the monitor for you.

This was my first ever OLED monitor that I purchased. The blacks on the screen are obviously alot better then on my laptop's IPS panel because of its true black oled pixels making story games actually look fantastic. Additionally the monitors software settings are actually pretty neat, the night vision feature actually is useful in some FPS games where the game itself just has everything set too dark at night so I used it a few times. It came with a HDMI cable and connecting it was simple and I'm able to run it in a dual monitor set up with my laptop without any issues at all, and basically 0 technical effort needed to do that. The colours are also alot more vibrant and when HDR works it works well.My only issues are that, trying to use HDR on games often ends up being more of a hassle then its worth because of how windows and the games interact with each other often causing it to glitch out. The monitor itself is fine and its easy to activate HDR with it but microsoft and game devs really need to make it alot less painful to try and do HDR while gaming. The only other issue I have is that the monitor doesn't have speakers which is a shame if you want to take your headphones off while watching a video since wearing them all the time can be fatiguing. I am also worried about burn in but we'll have to see in 2-3 years I suppose.Overall, If you have the money I'd say go for it since an OLED monitor nothing really comes close in picture quality and colours but just be prepared to either deal with headaches with setting HDR up or just use it in SDR since it looks really good without all the hassle.
