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.

    Was really excited for this monitor. It took 2 weeks to get here and I went to unbox it, kinda beat up packaging which I didn’t think much of because the actual monitor box was inside, and it was dead on arrival. Won’t show any signs of life besides the power led. Screen won’t turn on.

  5. OLED all the way!

    Came from a 2k Dell 150 hz monitor with a 2070 super. New machine with a 5090 and paired with this monitor wow! A lot of cash but worth it if your a serious gamer. People say that text is blurred on OLEDs. Not with this one.

    Best of the best. Even those who don’t usually care for tech had nice things to say when I got it. Truly a game changer for gaming when it comes to gaming for both single and multiplayer games due to the great color and high refresh rate.

    I tried to test it out in store before purchase, and while I could tell the difference, it wasn’t until I had one personally did I really see the drastic difference between my old 4k VA and this one. I would recommend adjusting the color a bit if you notice something’s off. Supposedly these are not calibrated as nicely as the URX model and I personally had to drop the red a few points and it’s all good – worth the savings in my opinion.

    I will also note that despite having VRR/G-sync off, I don’t see any screen tearing – in case you’re worrying about any potential vrr flicker. Display screen compression hasn’t been noticeable as well.

    Excellent choice for those looking for a 4k 240hz OLED monitor. Easy to install and picture quality is superb. MSI Care also is really great, and the monitor and OLED care software receives updates regularly
