Support for 1.07 billion colors with 99% coverage of the DCI-P3 color gamut and VESA DisplayHDR True Black 500 certified HDR deliver cinematic visuals. FreeSync Premium Pro technology synchronizes the display's refresh rate to the frame rate of the graphics card to greatly reduce or eliminate stuttering screen tearing during gaming and video playback. Connect your device through the DisplayPort 2.1 and dual full-bandwidth HDMI 2.1 ports. The back features a USB-C connector that transfers video, data, and up to 90W of power to compatible devices. A second, data-only USB-C port gives you access to a built-in USB 3.2 Gen 1 hub that allows you to connect peripherals such as a mouse, keyboard, or flash drive through the monitor. Using the KVM switch allows you to change control between two devices using a single mouse and keyboard. Plugging your favorite headphones into the 3.5mm audio jack provides listening privacy. Use the included remote control to adjust the screen settings from the comfort of your couch.

BenQ EX321UZ Reviews

4th Gen QD-OLED is here!

By dular
Rated 5 out of 5
Date: 2026-06-09

Here's a polished version: > The blacks are incredibly deep, and the colors truly pop. It comes with everything you need right out of the box and costs about $200 less than the ASUS PG32UCDM. In addition, I believe the ASUS model uses a 3rd-generation OLED panel, while the BenQ features the latest 4th-generation panel technology. Overall, the BenQ offers outstanding image quality, newer panel technology, and better value for the money.
