Overview
At 38 inches, the 38" BenQ EX381U is a large 4K IPS gaming monitor with 144 Hz refresh and DisplayHDR 600. It suits players and creators who want a television-like screen size without leaving the desktop monitor format. It combines 3840 x 2160 resolution, 98% DCI-P3, 600 cd/m² peak brightness, HDMI 2.1 and 90W USB-C. The 1 ms MPRT result depends on strobing, while the ordinary GtG figure is 5 ms. IPS contrast is only 1000:1, the stand does not pivot and the large panel demands substantial desk depth and GPU power. Buy it if you want a large 4K 144 Hz screen with USB-C and credible mid-tier HDR; skip it if you need compact dimensions, deep native blacks or portrait rotation.
Key Highlights
- 3840 x 2160 on a 38-inch IPS (Innolux) panel defines the monitor's core image format.
- 48 Hz - 144 Hz refresh and 5 ms GtG / 1 ms MPRT response figures set its motion priorities.
- 350 cd/m² typical brightness with 1000 : 1 contrast gives the realistic SDR baseline.
- 2 x HDMI 2.1; 1 x DisplayPort 1.4 cover the main video inputs.
- USB-C is listed as 1 x USB (Type-C; Gen 1; upstream; data only) / 1 x USB 3.2 (Type-C; Gen 1; upstream; 90W; DP Alt Mode) / 1 x USB 3.2 (Type-C; Gen 1; downstream; 7.5W); DP Alt Mode and wattage determine laptop usefulness.

HDR & Brightness Reality
38" BenQ EX381U carries DisplayHDR 600, with 600 cd/m² peak brightness and 350 cd/m² typical output. That gives highlights more room than a basic 400-nit badge, while 98% DCI-P3 coverage supports wider HDR colour. The limit is the 1000 : 1 IPS contrast ratio, so dark-room blacks will not match OLED or a strong local-dimming display. HDR should look meaningfully brighter, but not deliver deep cinematic contrast.

Pros & Cons
- 3840 x 2160 resolution on the 38-inch panel matches the monitor's stated role.
- 48 Hz 144 Hz refresh and 5 ms GtG / 1 ms MPRT response figures support the published motion use.
- 350 cd/m² typical brightness provides the stated full-screen baseline.
- 98% published colour coverage supports the intended office, gaming or media role.
- 100 mm height adjustment improves desk ergonomics.
- The 1 ms MPRT result depends on strobing, while the ordinary GtG figure is 5 ms
- IPS contrast is only 1000:1, the stand does not pivot and the large panel demands substantial desk depth and GPU power
- USB-C capability is limited to the published specification: 1 x USB (Type-C; Gen 1; upstream; data only) / 1 x USB 3.2 (Type-C; Gen 1; upstream; 90W; DP Alt Mode) / 1 x USB 3.2 (Type-C; Gen 1; downstream; 7.5W).
- HDR capability remains bounded by 350 cd/m² typical brightness and 1000 : 1 contrast.
