Style: 32" OLED 4K 240Hz UHD G-SYNC
This review is for the ASUS PG32UCDM, which is a QD-OLED monitor sporting a 240hz refresh rate and 4K resolution to clarify when Amazon lists all the reviews together in the way they do. Gaming performance: At 240hz, provided your graphics card can push pixels that quickly, this monitor is at the top of the game when considering the speed of competitive 4K monitors. There does not currently (2/24/25) exist a 4K panel that can do more than 4K 240hz, if you require more for competitive gaming then you should look elsewhere to a 1440p monitor or the like. I played Halo Infinite at 240hz and the experience was divine. Coming from a 144hz 4K 27" IPS panel, there is no comparison: the picture was unimaginably clear, vivid, crisp, and with dark blacks. Age of Empires IV with HDR mode enabled looks like a different game entirely. I will have to replay every older game I own with this monitor. The colors quite literally give life to old games and show you things in titles you've already played that you may have missed on your older monitor. Other media consumption: I do not own a TV, thus I consume all of my media through my computer and a monitor that could natively display all current types of media formats (HDR, Dolby Vision, etc) was important to me and this monitor excels in media consumption much like an OLED TV does. This monitor supports Dolby Vision which is quite uncommon among computer monitors, competitor's products that I've checked during my research prior to buying (Gigabyte F032U2P as well as the MSI equivalent) fall short in this area, not supporting DV. Switching HDR modes is easily accessible in the monitor settings. HDR support is excellent just the same as DV and is the default mode. Just like with games, true blacks show with OLED panels such as this one because the pixel completely turns off, unlike other panels where local dimming and other technologies try to reproduce black shades but they often come out gray as some light from the backlight shines through. Not the case with this monitor. The dark, eerie, emptiness of space in 1979's Alien really comes through and the vivid colors of Avatar shine bright as if you were really on Pandora. I cannot express enough how important a good monitor is when putting together a gaming or media setup. It is the primary way you interact with your computer. Things to know: OLED is susceptible to burn in, and as in the old days with CRTs (which were also prone to burn in), care must be taken to mitigate the effects. It's the return of the screen saver. The monitor comes with a standard 8 hour pixel refresh cycle which prompts you with the on screen display to run a pixel refresh. It takes about 5 minutes to complete, and you can postpone it if you so wish. It is also recommended to use a dark windows theme, no background, auto-hide taskbar, among other mitigation measures. Text fringing: I thought this would be a problem for me, since I am both easily nauseated by blurry text and use my computer for a lot of text-based work as well (coding and writing these reviews...). Truthfully it is only noticeable if you get very, very close to the screen, much closer than is usable. There are also mitigation measures you can take for this such as using different fontpacks and so on. Overall, this monitor is excellent and I forsee using it for 5+ years. I will edit this review if burn in appears in any significant or severe way or earlier than expected.

Style: 27" OLED QHD 0.03ms 240Hz G-SYNC True 10...
Absolutely Stunning Gaming Monitor – Worth Every Penny! I’ve been using the ASUS ROG Swift for a few weeks now, and it has completely blown me away. The OLED panel is gorgeous—colors are rich, blacks are truly black, and the 99% DCI-P3 coverage makes everything from games to movies look jaw-droppingly good. The anti-glare micro-texture coating is also a game changer; I can play during the day with sunlight in the room and still see every detail clearly without annoying reflections. Performance-wise, this thing is a beast. The 240Hz refresh rate combined with the insanely low 0.03ms response time makes gameplay feel buttery smooth and responsive. Pair that with G-SYNC compatibility and I’ve had zero screen tearing or stuttering—it feels like cheating in fast-paced shooters. Build quality is exactly what you’d expect from ASUS ROG: sturdy, premium, and sleek. The stand is solid and offers great adjustability, while the overall design has that ROG flair without being over the top. Setup was simple, and I appreciate having both DisplayPort and HDMI options. If you’re a competitive gamer or just someone who wants one of the best displays on the market, this monitor delivers in every way. It’s not the cheapest option out there, but the performance and visual quality easily justify the price. Highly recommend—easily the best monitor I’ve ever owned.

Style: 32" OLED 4K 240Hz UHD G-SYNC
If you’re looking for the ultimate gaming experience, the ASUS PG32UCDM delivers in every way. I’ve tested this monitor extensively, especially paired with my Xbox Series X, and it’s hands down one of the best displays you can get right now for serious gaming. First off, the 32-inch 4K OLED panel is absolutely stunning. The image clarity is razor-sharp, colors are vibrant, and the blacks are deep and inky thanks to true OLED contrast. This is a huge advantage in dark, atmospheric games where detail and immersion matter. The 240Hz refresh rate and 0.03ms response time are game-changers, especially if you’re into fast-paced shooters or competitive titles. Even on Xbox Series X, where most games top out at 120Hz, the motion clarity is buttery smooth, and there’s virtually no ghosting or input lag. It feels incredibly responsive, which gives you that extra edge in tight, high-stakes matches. Another killer feature is FreeSync Premium Pro support, which eliminates screen tearing and stuttering, keeping gameplay fluid and clean no matter what’s happening on screen. Combined with HDR10 and Dolby Vision, this monitor brings out incredible depth and realism in Xbox Series X games like Cyberpunk 2077, Forza Horizon 5, and Halo Infinite. I also appreciate the thoughtful design—plenty of connectivity options (including HDMI 2.1 for full next-gen console support), customizable RGB lighting, and intuitive OSD settings that make it easy to tweak the experience for different genres or setups. In short, the ASUS PG32UCDM is a beast. Whether you’re gaming on PC or console, it offers elite-tier performance, gorgeous visuals, and all the right features to give you a competitive advantage. It’s not just a monitor—it’s a serious upgrade to your entire gaming experience.
