    Outstanding 4K OLED With Excellent Accuracy

    This is one of the best gaming monitors I have used. The combination of 4K resolution, a 27-inch screen, OLED contrast, and a 240Hz refresh rate provides an exceptionally sharp and responsive experience. Fine details in character models, environments, hair, weapons, and distant objects are noticeably clearer than my old 1440p display The factory color accuracy on my unit was excellent. Using the factory 6500K preset on wide gamut setting, I measured approximately x 0.3119 and y 0.3293, which was only about a ΔE00 of 0.8 from the D65 target. This was measured at roughly 397 cd/m², so the monitor was already remarkably close to an accurate white point before calibration. After calibration, colors appear natural and consistent without losing the vibrant presentation that QD-OLED is known for. The wide color gamut gives games and HDR content a striking appearance, especially during colorful effects, explosions, and bright highlights. For accurate SDR content, the calibrated D65/sRGB presentation still looks rich while avoiding oversaturation. Black levels, contrast, shadow detail, and overall image depth are excellent, particularly in a darker room. This monitor is an excellent choice for price compared to the PG series for those who want premium 4K gaming performance with surprisingly good factory calibrated colors.

    Absolutely stunning OLED for gaming and media

    This OLED completely transformed my setup. The colors, contrast, and response times are honestly on another level. I uploaded a picture of my setup with the OLED beside another display, and the difference is immediately noticeable. The center OLED has true blacks and incredible contrast, while the monitor on the right looks washed out and gray in comparison even though they’re displaying the exact same image. That side-by-side comparison alone made me realize how massive the jump to OLED really is. Dark scenes actually look dark instead of glowing gray, and highlights pop so much more naturally. Gaming feels insanely smooth at 120Hz with near-instant response times, and movies/content look cinematic especially in darker rooms. It also completely upgraded the overall aesthetic of my desk setup. Thin bezels, amazing panel quality, and the image clarity make everything feel premium. Easily one of the best upgrades I’ve made for both gaming and entertainment. Would absolutely recommend to anyone considering OLED.

    Absolutely the Best Gaming Monitor I’ve Ever Owned

    I’ve owned a lot of gaming monitors over the years, and this one is on another level. The OLED panel produces incredible colors, perfect blacks, and amazing HDR that makes every game look stunning. The 4K resolution is razor sharp, and the 240Hz refresh rate makes gameplay feel incredibly smooth on PC while still giving my PS5 an excellent 4K 120Hz experience.

    Amazing picture

    The colors are so vibrant and crisp it is absolutely awesome! I initially bought the 2k oled with 400 fps but didn't notice much of a difference so I got the 4k with a glossy screen . I wasn't sure how it would be with a glossy screen but I don't even notice it has a glare. Absolutely worth going for the true blacks and colors of a 4k monitor with less FPS rather than /k oled with more fps. Very happy with my monitor and would absolutely recommend it !

    asus 4K 27 inch 240hz OLED monitor

    asus 4K 27 inch 240hz OLED monitor has a very clean and clear beautiful display. Colors are rich and vibrant. Peak brightness and deep blacks are showing me things I’ve never seen before in games I play. I highly recommend this product. Easy assemble. Make sure you buy a new microfiber cloth to keep it clean. Don’t recommend the one in the box. It will take a lot of time to clean if any type of oils touch the panel. Make sure you buy good distilled water to keep it clean. Some distilled water will leave smears.

  • I got the monitor and have it set on HDR mode. I tried all HDR modes including Gaming HDR and Console HDR but the brightness is low even when I set the monitor brightness to 100. I tried HDR collaboration, turning off HDR in windows setting and in game.

    If the brightness is low even after setting the monitor brightness to 100 in Windows, open the on-screen display (OSD) menu using the physical joystick, navigate to the Image or Brightness settings, and raise the value or turn off restrictive options like Uniform Brightness. Additionally, disable Auto Logo Brightness and Power Saving modes if your screen feels artificially dimmed during use.
