Glossy vs Matte

The ASUS glossy finish is a game-changer for picture clarity—colors pop more and blacks look deeper. However, in a bright room with windows, the reflections can be distracting. The Samsung matte coating is best-in-class for diffusing glare but slightly softens the 'OLED pop'.

Which should you buy?

Buy the ASUS if:

  • You want the 'inkiest' blacks (Glossy WOLED)
  • You play at 1440p to keep high framerates
  • You game in a dark or light-controlled room

Buy the Samsung if:

  • You want the sharpness of 4K
  • You have a powerful GPU (RTX 4080+)
  • You want to use your monitor as a TV for Netflix/YouTube
