Further information on supporting our work.Fast IPS panels are a popular choice when it comes to high refresh rate gaming at a range of resolutions. With high frame rate competitive play in mind, the Full HD resolution is the most forgiving. This is what the ASUS XG249CM offers. As a member of the ROG Strix Series, the monitor has ‘gamery’ styling to the stand. But is free from flashy colourful elements. The top and side bezels are slender, with thin panel borders flush with the rest of the screen. And a slim hard plastic outer part. The OSD (On Screen Display) is controlled by a joystick and buttons at the rear, running down the right side as viewed from the front.
A 23.8″ IPS-type panel is used, with 1920 x 1080 (Full HD or 1080p) resolution and support for a 270Hz (240Hz + internal factory overclock) refresh rate. We believe this to be the BOE MV238FHM-NG2 IPS-ADS panel, more specifically. Adaptive-Sync is supported, including AMD FreeSync Premium and Nvidia’s ‘G-SYNC Compatible Mode’ with a 48 – 270Hz VRR range plus LFC. Other aspects to note include a matte anti-glare screen surface, 1000:1 static contrast ratio and 178°/178° viewing angles. 8-bit colour support is included, whilst the screen is factory calibrated with a specified DeltaE <2. A flicker-free WLED backlight delivers a 350 cd/m² typical maximum luminance and ~sRGB colour gamut. Basic HDR10 support is included, allowing 10-bit processing to be used but very limited in terms of colour gamut, peak luminance and contrast (no local dimming requirement).
A 1ms grey to grey response time is specified, which as usual you shouldn’t pay too much attention to. ELMB Sync is also supported, a strobe backlight setting which can also be used with Adaptive-Sync if you wish. The screen attaches to the stand using a quick-release mechanism, with the stand removable to reveal 100 x 100mm VESA holes for alternative mounting. The stand is fully adjustable, including height adjustment (100mm or 3.94 inches) and pivot. The ports face downwards and include; DC power input (external ‘power brick’), HDMI 2.0, DP 1.2a+ (HDR feature set), USB-C (DP Alt Mode, 15W PD and upstream data), 2 USB 3.1 ports (plus upstream) and a 3.5mm headphone jack. The monitor includes KVM functionality, allowing connected USB peripherals to be shared between multiple systems.
Further details can be found on the on the manufacturer’s website. The monitor is listed for ~$260 USD.
