For a long time users had to choose between high resolutions or high refresh rates. The ‘4K’ UHD resolution is most commonly associated with 60Hz displays, although some models do drive that up further. The ASUS VG28UQL1A, of the TUF Gaming range, is one such model and provides a high refresh and high resolution experience via both DisplayPort and HDMI. The monitor has the robust look associated with the series, with plenty of matte black plastic. The top and side bezels are fairly slender, a dual stage design with a slim panel border that’s flush with the rest of the screen. And a slender hard plastic outer edge. The OSD (On Screen Display) is controlled by a joystick and buttons at the rear of the monitor, running down the right side as viewed from the front.
The monitor uses 28″ 3840 x 2160 (‘4K’ UHD) IPS-type panel, more specifically a member of the Innolux M280DCA AAS (Azimuthal Anchoring Switch) family. The monitor supports a 144Hz refresh rate alongside Adaptive-Sync, including AMD FreeSync Premium Pro with an assumed 48 – 144Hz VRR range plus LFC. A matte anti-glare screen surface is used and a 1000:1 static contrast ratio and 178°/178° viewing angles are specified. 10-bit colour is supported and a (presumably flicker-free) WLED backlight is employed, offering a 90% DCI-P3 (125% sRGB) colour gamut and 400 cd/m² typical maximum luminance. Low Blue Light (LBL) settings are expected to feature. VESA DisplayHDR 400 support is included for a basic HDR experience, allowing the quite generous colour gamut and 10-bit colour reproduction to be used effectively. It does not require local dimming or particularly high luminance output, however. A 1ms grey to grey response time is specified (approach with caution), with variable overdrive included to improve tuning at reduced refresh rates. ELMB Sync strobe backlight mode is included. This can be used in conjunction with Adaptive-Sync. The stand attaches centrally via 100 x 100mm VESA and can be removed to make way for an alternative VESA 100 solution. Based on other models with the design, we expect full ergonomic flexibility from the stand. The ports face downwards and include; DC power input (external ‘power brick’), 2 HDMI 2.1 ports, DP 1.4 (with DSC) and a 3.5mm headphone jack.
