12 min read5 products evaluated

4K needs a strong GPU for games, but it gives the sharpest desktop at this size. Every monitor here is 4K, ordered by refresh rate.

The order reflects refresh rate, resolution and size from maker specifications; a missing panel is flagged, not filled in rather than guess, since we have not benched them.

Our Picks

Alienware AW2725Q 4K QD-OLED

Also Consider1 of 5

Alienware AW2725Q 4K QD-OLED on Amazon (opens in a new tab)

Alienware's AW2725Q is a 26.7-inch 4K QD-OLED at 240Hz with USB-C and a height, tilt, swivel and pivot stand.

Best for

Buyers who want Dolby Vision support.

Skip if

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

Why we like it

It has one of the most adjustable stands among the OLED models here. It matches the MO27U2 on refresh rate (240Hz). On screen size it trails the group at 26.7 inches, while the Odyssey Neo G7 43 comes in at 43 inches.

Like the MO27U2, it has a QD-OLED panel, while the MAG 274UPF uses a rapid IPS panel. It is the only pick here with a DisplayHDR True Black 400; the MAG 274UPF has an HDR 400 instead. It also offers Dolby Vision support, 166 PPI at 4K and USB-C with 15W power delivery.

Reaching 240Hz at 4K needs DisplayPort 1.4 with DSC or HDMI 2.1 on your graphics card, and a GPU able to render well above 100fps at 4K. Leave the maker's pixel-refresh routines enabled and hide static taskbars to limit burn-in risk. Its price falls between the MAG 274UPF and the MO27U2, based on our last check.
