Quick verdict

The EX321UX is the big-screen Mini LED choice for players who want intense HDR and a flexible console setup without OLED care. Tom's Hardware measured about 1,300 nits in a 25% HDR window and 750 nits in SDR, praised its video processing and low input lag, and found no ghosting with its overdrive. Three HDMI 2.1 ports, one with eARC, make it easy to connect consoles and a soundbar.

Tom's Hardware found local dimming locked out of the accurate sRGB and P3 modes, and there is no backlight strobing or speakers. At 144Hz it is not a competitive-shooter monitor.

These are third-party results, not our tests. Different outlets use different methods, so compare numbers only within the same source.

Motion, response, and latency

Tom's Hardware found minimal blur and no ghosting with the AMA overdrive and low input lag. There is no strobing mode. At 144Hz each frame lasts about 6.9 ms on a sample-and-hold display.

Image quality and HDR

Tom's Hardware measured about 1,300 nits in HDR at a 25% window and 750 nits in SDR, with about 104% DCI-P3 coverage. Local dimming is unavailable in the Display P3 and sRGB modes, a trade-off for color-critical work.

Connectivity, PC, and console notes

DisplayPort 2.1, three HDMI 2.1 ports (one with eARC), USB-C video input, USB hub, and KVM (per the listing).

Warranty and ownership

As an LCD, no burn-in concern. Warranty terms not verified.
