Experience finest details on the 27" VA panel thanks to QHD resolution and HDR 400. A refresh rate of 165 Hz, 1 ms response time and AMD FreeSync 2 deliver excellent gaming experience. Comes with AOC Game Lights and Game Pad.

AMD FreeSync 2 HDR

AMD’s FreeSync 2 improves upon its predecessor FreeSync, keeping the support for variable refresh rate synced with the GPU’s framerate, but also including gaming-specific HDR (High Dynamic Range) support, which reduces the input lag versus conventional HDR monitors. Stricter requirements and enforcement of Low Frame Compensation (LFC) technology will ensure smooth, latency-, stutter- and tear-free gaming, now with a higher dynamic range.

VESA DisplayHDR 400

The first tier in the VESA certification for High Dynamic Range, the DisplayHDR400 specifies true 8-bit image quality, global dimming, peak luminance of 400 cd/m², lower black levels, higher contrast and higher colour gamut coverage. Experience mind-boggling vibrant and even more immersive gaming thanks to DisplayHDR400!


A 165Hz refresh rate, well over twice the industry standard of 60Hz, makes games run smooth as silk. Realize the potential in your graphics card. Forget screen tearing and forget motion blur. Feel your reflexes become one with the action. Never look back.

This is not a cheap monitor. I think it is important to get that out the way. To find something that supports high refresh rate gaming through Freesync or G-Sync, on a large panel with higher than 1080p resolution is quite hard within a budget. When building a PC for Workstation or Gaming purposes it's important to factor in the cost of the Monitor too. There is categorically no point in spending over 1000 on a PC only to hook it up to a rubbish screen. The monitor has a lot of configuration options but there are profiles pre installed too. We have found it to be really immersive in colour-rich games like Fortnite, and with a powerful GPU, the Freesync 2 technology really makes a difference in games over 100 fps. Stand is really sturdy. My tip for this monitor would be to make sure you install the actual drivers from the CD-ROM or the Website as Windows will use a generic PNP Monitor driver which doesn't give you the best feature control in the AOC App from the website. The other thing to do is go in to display advanced properties and make sure you enable 165hz otherwise you've spent a lot of money for regular 60hz.
