Higher resolution improves detail but increases GPU workload at the same settings. Choose a target that your system can sustain in the games you play.
A high maximum refresh rate is most useful when the PC can produce frames consistently and input latency matters. Adaptive sync helps when output moves below that ceiling.
IPS, VA and OLED panels differ in contrast, response transitions, viewing angles and price. Compare measured behaviour instead of assuming one label guarantees quality.
HDR requires more than accepting an HDR signal; brightness, contrast and local dimming or per-pixel control shape the result. VESA DisplayHDR certification provides one comparable reference point.
Height, tilt, swivel and VESA mounting affect long-session comfort. Ports must also carry the intended resolution and refresh rate from the selected PC or console.
