240Hz is the line where motion starts to look noticeably smoother for this kind of setup. Every monitor here refreshes at 240Hz or more, uses an OLED panel and refreshes at 120Hz or more, ordered from the lowest price.

We ranked these monitors on refresh rate, resolution and size using manufacturer specifications; where a maker leaves out HDR, we say so rather than guess, since we have not benched them.

Worth skipping when oLED burn-in risk with static desktop element is a problem.

Why we like it

The maker publishes few details on ports and stand. It has a zero-bezel design on all four edges for multi-monitor rows, and a glossy WOLED coating keeps blacks deep in bright rooms. On screen size it ties with the Q27GAZDV and the MO27U2 at 27 inches.

Like the Q27GAZDV and AG276QZD2, it has a 2560x1440 (1440p) resolution, while the MO27U2 uses a 3840x2160 (4K) resolution. No other pick in this guide offers a W-OLED panel; compare the MO27U2, which has a QD-OLED panel. It also offers a 240Hz OLED panel at an entry-level OLED price at the time of writing.

To see 240Hz at 1440p, connect over DisplayPort or HDMI 2.1; older HDMI 2.0 ports cap the refresh rate lower. It undercut the Q27GAZDV and every other pick on price at the time of writing. The main gap: screen size of 27 inches, behind the AW3425DW (34.2 inches). If that matters, the AW3425DW comes in at 34.2 inches.

Why we like it

HDMI 2.1 and DisplayPort 1.4 inputs cover a PC and a current console on one screen, and a USB 3.2 hub sits in the monitor. It matches the GO27Q24G and the MO27U2 on screen size (27 inches). It shares a 2560x1440 (1440p) resolution with the GO27Q24G and AG276QZD2; the AW3425DW goes with a 3440x1440 resolution.

A 110% DCI-P3 color gamut is unique to it among these picks, while the AW3425DW uses a 99% DCI-P3 color gamut. You also get a USB 3.2 hub and VESA mount compatibility. To see 240Hz at 1440p, connect over DisplayPort or HDMI 2.1; older HDMI 2.0 ports cap the refresh rate lower.

Leave the maker's pixel-refresh routines enabled and hide static taskbars to limit burn-in risk. G-SYNC Compatible works on NVIDIA cards over DisplayPort, and FreeSync covers AMD cards. When we checked, only the GO27Q24G cost less, and the AG276QZD2 cost more.
