AOC AG273QCX: WQHD 144Hz Gaming Monitor with FreeSync 2 HDR and 0.5ms Response Time (AOC AG273QCG)

By November 29, 2017 4 Comments



AOC plans to break the 1ms response time speed barrier with its recently announced AOC AGON 3 AG273QCX and AG273QCG gaming monitors. The AGON III series also includes the AOC AG273UG with 4K 144Hz and G-Sync HDR as well as the QHD ultra-wide AOC AG353UCG with 200Hz and G-Sync.

The AOC AG273QCX also features AMD FreeSync 2, 144Hz refresh rate, and HDR support for the next-level gaming experience. The AOC AG273QCG, on the other hand, will offer G-Sync and 165Hz but no HDR support. Both displays feature a wide-gamut TN panel with 2560×1440 QHD resolution and the revolutionary 0.5ms response time speed.

HDR and TN Panel?

Although the AOC AGON AG273QCX and AG273QCG have a TN panel, AOC claims it will have an image quality similar to the quantum-dot IPS, if not better – due to the wide color gamut, but they didn’t reveal much about it. Whether this is actually feasible remains to be seen, however, the viewing angles will certainly stay TN-like with 170/170 degrees.

The new curved TN panel of the AOC AG273QCX is developed by AU Optronics and uses HDR (High Dynamic Range) to extend the color and contrast range, but with only 400-nits peak brightness the HDR support is only partial. For Full HDR support, a display needs at least 540-nits, 4K resolution, and 10-bit color support.

Better image quality than the IPS and VA or not, the AOC AG273QCX FreeSync 2 monitor will still raise interest in a lot of gamers as a curved TN panel gaming monitor with 0.5ms response time.

The AOC AGON 3 AG273QCG has no HDR support, but G-Sync, 165Hz, and 0.5ms response time are more than enough to excite most of gamers. HDR isn’t supported as Nvidia has more strict requirements for the G-Sync HDR technology.

AMD FreeSync 2 and 0.5ms Response Time

Besides providing the display with the ability to support HDR content, AMD FreeSync 2 also solves the narrow range of the dynamic refresh rate. The LFC (Low Framerate Compensation) ensures that the upper range is at least 2.5 times greater than the lower end.

All FreeSync compatible graphics cards will also support FreeSync 2 and with the addition of the AMD Vega cards, players will be able to enjoy smooth gameplay at high refresh rates with no screen tearing and stuttering.

What we are most eager to see in action is the 0.5ms response time speed and whether it will actually perform as fast. AOC hasn’t revealed how they managed to achieve this speed, and whether the speed is specified as gray to gray (GtG) pixel transition, overdrive, or achieved by backlight strobing, so we’ll have to remain patient for now.


Price & Release Date

The AOC AG273QCX price is €600 (~$709); the release date is scheduled for April 2018. The G-Sync version, the AOC AG273QCG, is priced at €700 (~$827) and will be available in May 2018.

As all of the most anticipated gaming monitors of 2017 are being delayed, it seems that 2018 will be the ultimate gaming monitor year. This one belongs to the CPUs, for now.
