Pros & Cons
Pros
- Exceptional Picture Quality: The QD-OLED panel provides deep, inky blacks, vibrant colors, and high contrast that significantly outperforms IPS and VA panels. The glossy coating is frequently praised for making the image 'pop' and maintaining superior clarity in dark rooms.
- High-End Gaming Performance: With a 4K resolution and a 240Hz refresh rate, the monitor offers incredible motion clarity and responsiveness. Users report a 'buttery smooth' experience with near-instant response times that are ideal for both competitive and immersive single-player games.
- Competitive Pricing and Value: It is widely regarded as one of the most affordable 4K 240Hz OLED monitors on the market. Reviewers noted it provides the same high-quality Samsung panel as much more expensive competitors, making it a 'steal' for the specs provided.
Cons
- Intrusive OLED Care Maintenance: The 'Panel Protect' feature frequently interrupts users with un-dismissible pop-ups or forced shutdowns during active gaming or work sessions. Users report that the monitor remains unusable for 7-15 minutes during the cycle and often fails to turn back on automatically afterward.
- Limited Connectivity and Features: Compared to the URX model, this version lacks a KVM switch and only provides 15W power delivery over USB-C, which is insufficient for charging most laptops. Some users also found the power cord to be too short and the joystick controls on the back difficult to navigate by feel.
- Fragile Build and Slow Wake-up: The screen coating is reported to be extremely fragile and prone to micro-scratches even when cleaned with a microfiber cloth. Additionally, the monitor has a notably slow wake-up time from sleep mode, often taking 5-10 seconds to display an image.

Good..With Some Minor Setbacks
Verified purchase Verified purchase: This reviewer bought the product.Dylan S. Yankowsky February 24, 2025Review source: AmazonI have had this monitor for a few months now and for the most part, I love it. However, I do wish I could return this monitor for a 1440p monitor, especially now that I get random glitches on the screen. It used to be in the beginning that there would be weird horizontal lines across the bottom of the screen that look like pixelated lines only when I would start up the computer or when it would come out of playing a game. Now those lines are happening more frequently and sometimes I need to turn off my monitor in order to get it to stop. I have changed my display port cable and that proved it was not the problem.
Aside from the glitch lines, as another review mentioned, the OLED care will randomly have a pop up notification to use the OLED care now or when you turn your monitor off and it has happened to me while I was in intense fights in a game and it is very annoying this can’t be something turned off in the settings.
The last negative thing I will mention is it is in 4k and I haven’t seen an MSI OLED monitor that was 32inches and 1440p. Yes this monitor looks amazing and the glossy screen really does make colors pop. I turn off HDR because I don’t think monitors do well with HDR on windows because windows always seems to change color profiles randomly and I need to adjust settings constantly. Just turn off HDR, it looks better without it. But back to 4k, newer games are just too demanding and even the newest graphics cards and CPU’s struggle to keep games at 4k at max setting with frame rates over 60. 1440p really is the way to go and if you change the settings in windows, in games it looks fine and will run a lot better with max settings but browsing the internet and looking at text is noticeably worse.
Overall, in the future when we have better technology with PC parts to support 4k better, this would be a good choice but by that time, these monitors may be off the market. As of now, while being one of the cheapest options for 4k OLED monitors, just stick with 1440p.

Great monitor
Verified purchase Verified purchase: This reviewer bought the product.Jaden February 21, 2025Review source: AmazonProbably one of the best value 4k oled gaming monitors right now. At $800 nothing competes. The display is bright enough for my room and colors are so much better compared to my old ips monitor. At 240 Hz it’s smooth as butter. Exactly what I wanted and it delivers.

Amazing Picture Quality, better Price
Verified purchase Verified purchase: This reviewer bought the product.Jose Lara February 9, 2025Review source: AmazonI purchased this monitor when it was on a slight discount for 799.00. The first thing I did was update the firmware via displayport and set up my picture settings on the monitor and via windows 11. The picture quality on this thing while gaming looks incredible with HDR on. I play a lot of warzone and even with HDR off, the image quality is noticeably better than my old IPS display. The response time, paired with the refresh rate make this display perfect for FPS games. I’ve tried a few other options (42in C4, Samsung 32in Ultrawide Oled, and a Samsung 55in Oled), all of which were at least $200 more and this one is the best bang for your buck.

High Quality, Value-for-your-money Consideration for 4k OLED Gaming
Verified purchase Verified purchase: This reviewer bought the product.He Dai February 5, 2025Review source: AmazonThe MSI 321UPX 4K OLED Gaming Monitor is a total game-changer. Upgrading from a 60Hz 4K IPS monitor, the difference in both competitive and single-player games is dramatic. The 240Hz refresh rate makes gameplay incredibly smooth, and the inky blacks from the OLED display add amazing depth and detail.
I chose this monitor for its 4K resolution, fast refresh rate, and OLED tech, and it’s exceeded my expectations. The colors are vibrant, the response time is super fast, and it’s perfect for all types of games.
I’m excited to play upcoming titles, especially the new Monster Hunter!

USE the provided stand offs if you want to mount it on a arm mount.
MeepMeep February 2, 2025Review source: AmazonMounting was annoying. The provided screws weren’t long enough so when you tried to screw the vesa plate, it wouldn’t catch the threads in the hole.
You need to use the included standoffs..

The best value for the best QD-OLED panel!
Verified purchase Verified purchase: This reviewer bought the product.John Cunningham January 21, 2025Review source: AmazonI absolutely love this monitor.
For the longest time, this monitor was not recommended as you could not push software updates to it – that has been resolved. I successfully updated my monitor with no issues.
The picture is exactly what you expect for this Samsung QD-OLED panel – true black, ultimate clarity, 4K and 240hz.
Hands down, the 321UPX is the best value for this panel and I love the all black monitor!
