Our verdict

A fast QHD gaming monitor with a single cable USB-C input for laptops and a fully adjustable stand. It is heavy for its size, and the listing gives no brightness figure.

Overview

A Fast IPS panel with ELMB Sync backlight strobing is the core of this ROG Strix monitor, driving QHD at an overclocked refresh rate. A USB-C port with DisplayPort Alt mode lets a laptop connect over one cable alongside HDMI and DisplayPort.

QHD at this refresh rate gives sharper detail than Full HD esports panels while still serving fast shooters. The listing omits brightness and power use, and the stand makes it a heavy unit to move.

Who it's for

PC and console players who want resolution and refresh in one panel, and laptop users who like a single cable hookup. Buyers comparing HDR performance should look elsewhere since brightness goes unstated.

Pros and cons

Pros
  • QHD with very high refresh
  • USB-C DP Alt mode input
  • Full ergonomic stand adjustment
  • ELMB Sync with variable refresh
Cons
  • Brightness not listed
  • Heavy for a monitor this size
  • Only one HDMI port

Performance notes

Motion clarity comes from fast pixel transitions on the IPS panel plus backlight strobing that ELMB Sync runs together with variable refresh. Reaching the top refresh rate relies on overclocking the panel, so it needs a DisplayPort link and a GPU that can feed it. USB-C Alt mode carries video only as far as the laptop port supports it.
