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

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.
