LONDON, United Kingdom, April 21 | 2021 — ASUS Republic of Gamers (ROG) today announced that Strix XG43UQ, the world’s first HDMI® 2.1 gaming monitor, will be available in May. Strix XG43UQ features a 43‑inch 4K panel with up to a 144 Hz refresh rate and 1 ms moving picture response time (MPRT). It also includes Display Stream Compression (DSC) technology. The HDMI 2.1 port enables gamers to enjoy 4K 120 Hz gameplay on the latest consoles. The inclusion of AMD FreeSync™ Premium Pro technology ensures smooth HDR visuals with low latency, while ASUS Extreme Low Motion Blur Sync (ELMB Sync) works simultaneously with variable refresh rate technology to eliminate smearing and motion blur for fluid and responsive gameplay. Strix XG43UQ has a maximum brightness of 1000 nits – more than three times[1] that of OLED TVs. The monitor has a two-tone black and white finish with an all-white rear cover, and it features Aura Sync lighting technology for synchronised light effects with other Aura-enable components and peripherals.

Supersmooth true‑to‑life visuals
The 43-inch Strix XG43UQ features a 144 Hz, 4K (3840 x 2160) panel and AMD FreeSync Premium Pro technology to deliver super-smooth visuals at up to 144 frames per second. It’s also equipped with ASUS ELMB Sync which enables ELMB and variable refresh rate technologies to work simultaneously to eliminate ghosting and tearing for sharp gaming visuals with high frame rates.

In addition, High Dynamic Range technology with DisplayHDR™ 1000 certification and professional-grade 90% DCI‑P3 colour gamut ensures exceptional contrast and colours for true-to-life visuals.

Next‑gen gaming with HDMI 2.1
Along with offering amazing 4K 120 Hz gaming on the latest consoles via HDMI 2.1, Strix XG43UQ  includes an Auto Low-Latency mode to reduce input lag, with less than half the input latency of 4K TVs. It also has variable refresh rate (VRR) technology to decrease tearing and framerate stutter, and it utilises Display Stream Compression technology to transport ultra-high-definition video across a single high-speed interface with no perceptible loss in video quality.

Anti‑glare panel and rich connectivity
The anti-glare panel makes it easier to see what’s on-screen in bright environments, enabling a better viewing experience when watching movies or playing games. Strix XG43UQ includes an array of connectivity options such as USB 3.0, HDMI 2.1 and 2.0, DisplayPort 1.4, audio line-in, and an earphone jack. It also has a bundled remote control to enable users to adjust display settings easily.
