Coolermaster Mini LED Gaming MonitorDesign

This Monitor features a gaming-type design similar to other latest-gen monitors available in the PC gaming market. The RGB colour design is very similar to the Asus or Gigabyte monitors. The build quality of the Monitor is tough and durable. Coolermaster has manufactured the base stand of this Monitor that resembles their official logo. It has proper rubber feet that can withstand firmly against shocks or vibrations. It also comes with cable management clips.

The RGB Backlight is not so strong at the back of the monitor, so it won’t illuminate as brighter as you think you would. It only looks good when you are in a very dark room. The Monitor can be swivelled up 15 degrees from the viewing angle in both front and back directions. And with a height adjustable feature of 113 mm, this Monitor can be pivoted in 90 degrees direction.

All ports of this Monitor have been placed at the backside of the heavy screen unit. The screen unit is not bezel-less, and the sides of the Monitor look thicker than other monitors. A small logo of Coolermaster, like a hologram, is placed at the bottom middle area of the Monitor.
