Key takeaways

  • Input Lag: Under 15ms at 60Hz and under 10ms at 120Hz is the target. Above 20ms you will feel delay in shooters and fighting games.
  • Refresh Rate:

Native 120Hz is essential. Native 144Hz is a bonus for PC. Avoid 60Hz panels that use motion interpolation to claim “120Hz effective.”

  • HDMI 2.1 Features: Look for 48Gbps ports, VRR (HDMI Forum VRR, FreeSync, G-Sync Compatible), ALLM, and eARC. Not all HDMI 2.1-labeled ports are full-bandwidth — many are 24Gbps.
  • HDR Performance: True HDR needs high peak brightness and local dimming (OLED) or many dimming zones (Mini-LED). OLED wins for contrast, Mini-LED wins for brightness in bright rooms.
  • Response Time: OLED is near-instant 0.1ms. Good Mini-LED / QLED panels are 5-8ms. Slow VA panels can smear in dark transitions.
