E3: ASUS unveils ROG monitor with display stream compression

ASUS Republic of Gamers (ROG) has previewed a new 43-inch gaming monitor – the world’s first with display stream compression (DSC) technology – at the AMD “Next Horizon Gaming” event at E3 2019.

Display stream compression technology is an industry-wide compression standard for transporting ultra-high definition video streams across a single interface at high speed with no perceptible loss of visual quality.

With DSC technology, the new ROG monitor can display incredibly detailed and smooth visuals at native 4K resolution with a 144 Hz refresh rate via a single DisplayPort 1.4 connection without chroma subsampling, which can negatively affect visual fidelity.

Previously, to achieve this level of performance gaming, monitors needed two DisplayPort connections to transfer the video signal from the PC, which also often required complex driver configuration and prevented display of high-dynamic-range (HDR) content and variable refresh rates while gaming. The new ROG monitor eliminates these issues, supporting both HDR and variable refresh rates via a single DisplayPort 1.4 connection.

The new ROG monitor offers an immersive 43-inch big-screen experience without sacrificing the ultrafast and variable refresh rates usually only found in smaller panels. AMD Radeon FreeSync 2 HDR technology synchronises the monitor’s output to the GPU’s frame rate for smooth and stutter-free gaming, while optimised input lag gives competitive gamers a big advantage in timing-sensitive battles.

Support for HDR expands the contrast range and offers deeper blacks and brighter whites for a richer image with more depth than regular SDR. The new ROG monitor meets the VESA DisplayHDR 1000 specification with 10-bit image processing and 1000 cd/m2 peak luminance. Localised dimming plays an integral part in matching the VESA’s standard’s black level performance requirements, and 90% coverage of the DCI-P3 gamut quantifies the display’s colour output advantage.
