To make the most of 4K at 240Hz, connect a suitable gaming PC through DisplayPort 1.4 with DSC or an HDMI 2.1-capable source. The ASUS specification page lists both HDMI and DisplayPort vertical-frequency support up to 240Hz.

ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor HDR

HDR is one of the strongest reasons to consider an OLED gaming monitor. The ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor carries VESA DisplayHDR True Black 400 certification and is reported to reach up to 1,000 nits peak luminance on a 3% average picture level window.

OLED’s pixel-level lighting control allows dark areas to remain genuinely dark while bright highlights stand out. This can improve the impact of explosions, neon signs, sunlight, headlights, fire, reflections, starfield, and other high-contrast scenes in supported HDR games and movies.

Unlike traditional LCD monitors, OLED does not rely on a backlight that can glow behind dark pixels. This improves black levels and reduces blooming around bright objects on dark backgrounds. For cinematic and atmospheric gaming, this can be a major visual upgrade.

However, HDR results can vary according to the game, the source device, the operating system, selected monitor mode, ambient lighting, and the size of bright objects on screen. For the best experience, use HDR-aware content and configure HDR in both the operating system and the game.

The monitor also includes a Uniform Brightness setting in its on-screen display. ASUS says this mode reduces peak brightness to keep brightness levels more consistent as the size of bright windows changes. This can be useful for desktop work, reading, browsing, writing, and productivity use where consistent white-window brightness matters more than maximum HDR impact.

ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor Color

The ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor is not limited to gaming. Its 99% DCI-P3 color coverage and native 10-bit color depth make it suitable for users who work with vivid visual content, including photo selections, video projects, digital art, marketing assets, product images, and social-media graphics.

Wide-gamut coverage can make colors appear more saturated and lifelike, particularly in HDR games and media. QD-OLED technology is designed to combine OLED’s contrast capabilities with high color purity, helping create vibrant scenes with strong shadow detail.

For creators, this can be useful when reviewing campaign graphics, checking product photography, editing short-form video, creating visual assets, or preparing content for modern wide-gamut displays. The monitor’s 4K resolution also makes it easier to evaluate fine textures, detailed retouching, video frames, and interface elements.

For accurate professional production, use the relevant color mode, calibrate the display with suitable hardware if necessary, and work in a color-managed application. Wide color coverage is a strong starting point, but professional consistency depends on the full workflow—not just the monitor’s gamut specification.

For example, you can connect a gaming PC through DisplayPort, a PlayStation 5 through one HDMI 2.1 port, and an Xbox Series X through the second HDMI 2.1 port.

The integrated USB hub can also help simplify a desktop setup. You can plug a keyboard receiver, mouse receiver, controller cable, headset accessory, or other low-power USB device directly into the monitor, reducing the number of cables that must reach your PC.

One important buying check: official ASUS specifications cited here describe DisplayPort, HDMI, USB Type-A hub ports, and USB Type-B upstream. Verify the exact regional retail model and listing before assuming USB‑C video input or USB‑C power delivery, as third-party listings can sometimes conflict or combine features from other monitor models.

ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor OLED Care

OLED panels offer major visual benefits, but they also require thoughtful long-term use because static content can create uneven wear over time. ASUS addresses this through ROG OLED Care Pro, a protection suite designed to reduce burn-in risk.

The ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor includes a Neo Proximity Sensor. ASUS says this sensor can detect when the user moves away and automatically dim or black out the display, then restore the image when the user returns. This is intended to reduce unnecessary static-image exposure when the monitor is unattended.

Other OLED-care measures can include screen cleaning cycles, pixel-shift behavior, logo or taskbar protection, and screen-saver settings, depending on the monitor firmware and configuration. Use the monitor’s menu and ASUS Display Widget Center software to review and manage available settings.

To support OLED longevity:

• Allow the monitor to run its recommended panel-care or pixel-cleaning cycles

• Use automatic sleep or screen-off timers when stepping away

• Avoid leaving bright static windows, game HUDs, logos, or desktop elements on screen for extended periods

• Use dark mode where practical for desktop applications

• Enable available screen-protection features in the monitor settings

• Follow ASUS instructions for cleaning and maintenance

• Keep firmware updated when the manufacturer provides updates

These habits are sensible precautions, not a reason to avoid OLED altogether. For buyers who want outstanding contrast, HDR performance, and pixel response, OLED-care features help make the ASUS ROG Strix XG27UQDMS 27″ 4K UHD 240Hz QD-OLED Gaming Monitor more practical for mixed gaming and desktop use.
