Refurbished 37.5" 4K gaming monitor

The BenQ EX381U is a refurbished 37.5-inch IPS display built for 4K gaming at 144 Hz. It delivers 3840 x 2160 resolution with 1 ms GtG response time and 98% DCI-P3 colour coverage. HDR600 certification provides 600 nits peak brightness for specular highlights. Connectivity includes DisplayPort 1.4, HDMI 2.1 and a USB-C port with 90 W power delivery.

Suited to high-refresh 4K gaming with console audio

This monitor suits players who want a single screen for PC and current-generation consoles. FreeSync Premium Pro and HDMI 2.1 enable variable refresh rate at 4K 144 Hz from both sources. The integrated eARC port passes up to 7.1-channel audio to an external sound system. Buyers who need higher sustained brightness or deeper black levels should consider alternative panel technologies.

1 ms GtG response at 144 Hz 4K

The 1 ms grey-to-grey response time at the native 144 Hz refresh rate is the specification that determines motion clarity for competitive play. Combined with FreeSync Premium Pro, it keeps fast motion sharp without overshoot artefacts. If your workflow prioritises colour-critical work over gaming speed, a monitor with a lower response-time focus may be more appropriate.

Questions about this item

How do I connect the monitor so the 90 W USB-C port charges my laptop and carries 4K 144 Hz video at the same time?

Use a single USB-C 3.2 Gen 1 cable rated for DisplayPort Alt Mode and 90 W power delivery; the port handles both the 3840 x 2160 144 Hz signal and charging without extra adapters.

Which parts are most likely to need attention after a few years of daily gaming?

The IPS panel backlight and the 90 W USB-C power circuitry are the components that typically degrade first; the matte anti-glare coating is durable but can show wear if cleaned with abrasive cloths.

What is the first limitation I will hit during a long HDR gaming session?

Sustained HDR at 600 nits will trigger the monitor's thermal protection and dim the backlight before the 1 ms response time or 144 Hz refresh rate become limiting factors.
