4K needs a strong GPU for games, but it gives the sharpest desktop at this size. Every monitor here is 4K and can run 4K at 120Hz from a console, ordered by refresh rate.

The order reflects refresh rate, resolution and size from maker specifications; we did not test these monitors ourselves, and a missing HDR is flagged, not filled in.

Our Picks

MSI MPG 321URX QD-OLED

Also Consider1 of 5

MSI MPG 321URX QD-OLED on Amazon (opens in a new tab)

MSI's MPG 321URX is a 31.5-inch 4K QD-OLED at 240Hz with a built-in KVM, so one keyboard and mouse can switch between a desktop and a laptop.

Best for

Buyers who want built-in KVM with picture-in-picture.

Skip if

Look at the others if this bothers you: oLED burn-in risk with static desktop elements.

Why we like it

USB-C input rounds out the ports. It matches the MPG 272URX and the MPG 321URXW on refresh rate (240Hz). On screen size it ties with the MPG 321URXW at 31.5 inches.

Like the MPG 272URX and MPG 321URXW, it has a DisplayHDR True Black 400, while the CUNPU 4K uses an HDR400. It also comes with HDMI 2.1 and DisplayPort 1.4a inputs and an HDMI 2.1 input for consoles. 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 321UP and the MPG 272URX, based on our last check.

Best for

Spending as little as possible.

Skip if

Skip it if refresh rate matters most to you; the MPG 321URX offers 240Hz.

Why we like it

It is one of the cheapest 4K high-refresh monitors here. Its 160Hz refresh rate is the lowest in this group; the MPG 321URX leads at 240Hz. On screen size it sits mid-pack at 27 inches: the MAG 321UP comes in at 32 inches, and the MPG 272URX comes in at 26.5 inches.

No other pick in this guide offers a fast IPS panel; compare the MPG 321URXW, which has a QD-OLED panel.

It also offers 48Gbps HDMI 2.1 for consoles, a factory calibration of Delta E under 2 and 4K at a budget price tier.

Reaching 160Hz 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. It undercut the MAG 321UP and every other pick on price at the time of writing.
