What to know before buying

Listing details to confirm

Response-time claims conflict: the listing gives 0.5 Milliseconds and 0.5ms MPRT, while manufacturer details state 4 ms GtG. These are different measurement methods, so confirm the figure and mode relevant to your setup. The title lists HDMI 2.0 and DisplayPort 1.4, but the port details give no versions. HDR10 is listed, with no brightness or HDR performance context beyond a brightness value of 300. Check these details against the selected listing before buying.

Customer feedback highlights positive impressions of build quality and value, with comments also reporting no reliability issues. This is encouraging for buyers considering the listed QHD 144Hz desktop monitor, but customer impressions do not resolve the listing’s conflicting response-time claims. The feedback and rating mix is generally favourable, with a smaller one-star share, so it is not uniformly positive.
