Asus upgrades ROG Swift OLED PG48UQ monitor specs – 4K at 138Hz with HDR10

Still too big for a lot of gamers.

Asus PG48UQ

Asus has published the complete spec list for the massive ROG Swift OLED PG48UQ monitor, and some aspects are better than expected.

Announced back in January at CES 2022, PG48UQ was advertised as a 120Hz refresh rate monitor, but today Asus has managed to overclock it up to 138Hz. It’s just unfortunate that consoles don’t have an uncapped framerate to take full advantage.

This massive monitor measures 1,068mm (W) x 686mm (H) x 266mm (D) with a stand and weighs a hefty 16.2Kg. Its size may be too big for some desks, and if that’s your case, a 300x300mm VESA mount is available. Resolution is more than adequate at 3840×2160; anything less and the viewing experience may be impacted because of low pixel density.

Thanks to the 10-bit OLED panel, Asus’ display can achieve 133 per cent of sRGB and 98 per cent of DCI-P3 colour gamuts alongside 450-nits typical and 900-nits peak brightness, all while refreshing at a very fast 0.1ms (GtG). The panel also has an anti-glare coating to lower reflections.

Generally speaking, OLED goes hand in hand with excellent HDR representation since every single pixel is self-lit, meaning that in black images pixels simply turn off. This coupled to a high peak luminosity translates into a 135,000:1 typical contrast ratio and 1,500,000:1 maximum contrast in HDR.

Asus PG48UQ - IO

A gaming monitor can’t be called such if I/O is limited. Here, the brand opts for one DisplayPort 1.4 with Display Stream Compression (DSC), two HDMI 2.1, two HDMI 2.0, two 10W stereo speakers, a headphone jack and a USB hub comprised of four USB 3.2 Gen 1 Type-A ports. There is also a remote control for lazy people like me – now there’s no need to come out of bed to turn the screen off.

To finish gaming specs, Asus include features such as aiming crosshairs, factory calibration to a delta-E below 2, low blue light, flicker-free, and G-Sync technologies. Not forgetting the most important one to an OLED panel, a uniform brightness setting keeping levels consistent when viewing full-screen white scenes.

No word on pricing, but it looks like heck of a monitor for gaming aficionados.
