IMartz verdict

Pros

  • Outstanding image quality for a 1440p OLED
  • Very appealing glossy finish
  • Clearly improved SDR and HDR brightness over previous WOLEDs

Things to consider

  • Not the fastest OLED if maximum refresh rate is your priority
  • The glossy finish requires careful control of lights and reflections
  • Banding typical of WOLED panels

A good fit if…

  • Those seeking the best possible image quality in a 1440p OLED
  • Users who prefer glossy and deep blacks to a matte finish
  • Premium PC and console gaming with very good factory calibration

Consider another option if…

  • Your absolute priority is 360 Hz or more
  • A window or direct light reflects on your screen
  • Even slight banding or DSE really bothers you

Test note · EOTF tracking

TrueBlack 500 tracks the reference quite well, with slightly darker shadows and a small midtone boost. Unlocking brightness allows much stronger highlights, but brightens midtones considerably and reduces fidelity. As the lit area grows, available brightness falls and highlights are compressed.
