Product Description

Acer RT280KA 28" 4K UHD Monitor




Quality visuals

These displays deliver 3840 x 2160 4K UHD resolution for vivid images that look clear from any angle. You also get multiple display connectors to make it easy to connect any video source.


Good for your eyes

RT0 displays use Flicker-less tech to reduce eye-strain-causing screen flickering. Blue Light Filter tech lets you filter out strain-causing blue light when you have to work long hours, and Acer ComfyView tech reduces the light reflected off the screen.


Helping the environment

These displays are designed to reduce their impact on the planet. Their EcoDisplay design means they have ENERGY STAR 7.02 certification for being very energy-efficient, and they don't contain mercury. These displays and their packaging are also designed to be easily recycled.


No Screen Tearing

Say "goodbye" to stuttering and tearing. FreeSync and Adaptive-Sync technologies match the refresh rate of your monitor with your graphics card to provide the smoothest gaming experience.
