AOC recently announced their new AGON AG485UD display in China, a massive 48″ sized screen featuring a 4K resolution, 120Hz refresh rate and based on an OLED technology panel. This will offer another alternative to models like the Gigabyte Aorus FO48U and Skyworth G90 announced in the summer last year and aimed somewhat at the desktop market, despite the very large screen size. The OLED panel will offer per pixel dimming, exceptional contrast, excellent HDR performance and near instant response times that are all inherent to this technology.

0.1ms G2G Response Time and 120Hz for Gaming

The AG485UD will be able to offer near-instant response times thanks to its OLED panel, with a 0.1ms G2G figure quoted, something that is realistic for this kind of technology. There is a high refresh rate of 120Hz making it a good option for console gaming as well, and also support for adaptive-sync for VRR from both NVIDIA and AMD systems. Quick access buttons for the gaming preset modes are featured, and the screen is built to offer a low input lag as well for the 120Hz/VRR mode according to the AOC product page. Some familiar AGON gaming extras like dark field control, frame counter and refresh rate counter are also included.

Excellent HDR Performance with pixel level dimming

Being an OLED panel the screen can offer excellent per-pixel dimming to eliminate blooming and halos, and offer excellent contrast ratios. The peak brightness capability doesn’t seem to be listed on the AOC product page, but competing 48″ OLED displays can reach around 700 nits typically. The screen includes a wide colour gamut and 10-bit colour depth support though for HDR content. HDR10 input is supported here by the way, but unlike OLED TV’s like the popular LG CX and C1 series, there is seemingly no support for HLG or Dolby Vision standards which is a shame.

AOC AGON AG485UD other specs

The screen is 48″ in size and offers a 3840 x2160 “4K” resolution, 0.1ms G2G response time and 178/178 viewing angles. A wide colour gamut is available with 99% absolute DCI-P3 coverage (103% relative) quoted as well as 134% relative sRGB coverage. The screen comes factory calibrated with dE <2 quoted in the sRGB mode.

A spec of 450 cd/m2 brightness for SDR is quoted, based on a 25% APL. AOC also quote an up to 1.5 million:1 contrast ratio for this same

There is also a 10-bit colour depth listed

Despite the very large screen size the AG485UD will offer a versatile stand with tilt, 100mm height and swivel adjustments. This provides a lot more adjustability than you normally get from a large format display like this, although the usability and stability remains to be seen given the massive size.

HDMI 2.1 Included as well as DP and USB-C

The inclusion of 2x HDMI 2.1 ports should also mean support for high bandwidth 4K @120Hz for consoles, along with features like HDMI-VRR and perhaps even ALLM. Although we will need to wait for AOC to confirm these features and capabilities as per our recent investigation in to HDMI 2.1. AOC are also providing monitor-like connections here with DisplayPort 1.4 and USB type-C also available (DP Alt mode, 90W power delivery). There are also 4x USB ports available, an audio output, mic input and mic output included.

Picture by Picture (PiP) and Picture by Picture (PbP) modes are also supported. An easy to use KVM function is also included, and there are 2x 8W stereo DTS speakers built in. Familiar AOC LightFX RGB lighting is also available if you like that kind of thing.
