Overview

An OLED screen with high fluidity of 360 Hz

Enhance your gaming experience with the ASUS ROG Strix XG27ACDNG monitor! Immerse yourself in fluid and realistic images thanks to an OLED screen with 2.5K resolution, a refresh rate of 360 Hz and a fast response time of 0.03 ms. You'll also be more comfortable with its ergonomic stand, which allows you to position the screen in the ideal position.

OLED screen with 2.5K resolution

Immerse yourself in breathtaking visual precision with the ROG Strix XG27ACDNG. Its QD-OLED panel, combined with vivid 2.5K resolution and support for HDR 400 display, ensures a high-quality gaming and multimedia experience, bringing every detail to life with vibrant colours and remarkable clarity. Reduce lag and motion blur with a 360Hz refresh rate and a very fast 0.03ms response time (GTG). This combination ensures smooth, responsive gameplay, giving you the edge in fast-paced titles such as first-person shooters, racing games and real-time strategy games. React instantly to on-screen action and fire decisive shots with confidence.

Ultra-smooth display

As well as the fluidity of display made possible by a maximum frequency of 360 Hz, enjoy a tear-free gaming experience thanks to G-SYNC and FreeSync Premium Pro compatibility! This guarantees smooth, synchronised images by activating the variable refresh rate (VRR) by default. What's more, ELMB technology reduces ghosting and tearing for sharp images and high refresh rates during gaming.

Adjustable display format

For gamers who typically use smaller monitors, the XG27ACDNG is capable of displaying a 24.5-inch image, a 4:3 aspect ratio image or a full screen 4:3 aspect ratio image with deep black OLED borders around the image. For FPS gamers, playing in full screen 4:3 format allows game targets or character models to appear slightly larger, making them easier to hit.

    Pixel dead after 5 weeks!

    I'm extremely disappointed with the product... 1 dead pixel appears after just 5 weeks and 100 hours of screen use! Disgraceful!

    What about the Ldlc after-sales service? No support for 1 dead pixel, and it's the same cold shower for Asus support!

    I'd also like to point out the total lack of professionalism and empathy on the part of Ldlc's complaints department! After all this good and loyal service, it's all over for me! Where other brands would have at least made a gesture towards customer satisfaction, this is not the case here!

    In short, if you're looking for a so-called top-of-the-range screen, run away! And above all, don't buy it from them! If there's the slightest problem, you'll be on your own!

    Superb, comprehensive screen

    I chose this screen for a number of reasons.
    Firstly, I'm using it with a MacStudio as a secondary screen, so I can check out some renderings in 3D HDR imaging, and the Oled is amazing in terms of colourimetry and black depth (I have an Asus PA27JCV 5k screen as my main display and I can see the colourimetric balance).
    Secondly, I tested the screen with a PS5 PRO. It's night and day compared with an IPS screen.
    Brightness, contrast, high fluidity at 120Hz and HDR are all top-notch.
    Oled Care is very welcome, with a notification asking if you want to carry out pixel maintenance to prevent the screen from burning.
    You can set the frequency of the reminder, which is perfect.
    The glossy appearance of the screen is not a problem, but location and brightness will make all the difference.
    So far, I have no complaints or regrets about this purchase.

    Excellent

    After almost 1 year of use, I have to say that I don't regret my purchase at all. Between the excellent oled panel and its enormous refresh rate, I can only recommend it for this price.

    Opinion after 1 week's use

    After a week of intensive use, I'd like to share my thoughts on the ASUS XG27ACDNG 360Hz OLED screen, a real technological gem that has transformed my gaming and working experience. With its vibrant colours and striking contrast, it offers total immersion and remarkable fluidity thanks to its 360Hz. Whether you're a fierce competitor or an all-round user looking for performance and elegance, this screen will meet all your expectations. There was one slight drawback: activating G-Sync caused some annoying flickering. When deactivated, the problem disappears completely, allowing you to take full advantage of its exceptional image quality. ASUS manages to combine cutting-edge technology, refined design and versatility to deliver an unrivalled viewing experience. I highly recommend this model to those who aspire to excellence.
