AOC Gaming Monitor - 27" 4K Ultra HD

4K UHD (3840 x 2160 pixels) offers significantly more detail than FHD (1920 x 1080 pixels), resulting in sharper images. The U27G4R lets you switch between them for different gaming needs.

The monitor's OSD menu has options to change the resolution settings. The dual-frame feature allows for flexible switching between the two options.

A 320Hz refresh rate (at FHD) displays images up to 320 times per second, which reduces motion blur and makes fast-paced gaming smoother and more responsive.

Yes, the U27G4R supports DisplayHDR 400, which enhances the color and contrast for a more immersive viewing experience.

The monitor uses a Fast IPS panel, offering a fast response time of 1ms, ideal for gaming.

The monitor has an ergonomic stand that allows for height adjustment. Refer to the product specifications for the maximum height adjustment range.

AdaptiveSync (VESA Adaptive Sync) technology synchronizes the monitor's refresh rate with your graphics card's frame rate, reducing screen tearing and stuttering. It's highly recommended for a smoother gaming experience.

The AOC U27G4R has a 3-year warranty period.
