4K needs a strong GPU for games, but it gives the sharpest desktop at this size. Every monitor here is 4K, is curved and refreshes at 120Hz or more, ordered by refresh rate.

We ranked these monitors on refresh rate, resolution and size using manufacturer specifications; we did not test these monitors ourselves, and where a maker leaves out HDR, we say so.

Skip if

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

Why we like it

It also offers a 240Hz refresh rate and offers a 32 inches screen size. Nothing else here matches its 240Hz refresh rate; the Odyssey G7 37 comes closest at 165Hz. It matches the Odyssey Neo G7 on screen size (32 inches).

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. G-SYNC Compatible works on NVIDIA cards over DisplayPort, and FreeSync covers AMD cards. At our last price check it topped the group, with the Odyssey Neo G7 the nearest cheaper option.

Also Consider3 of 3

Samsung Odyssey Neo G7 32-inch on Amazon (opens in a new tab)

Samsung's Odyssey Neo G7 uses a Mini LED backlight behind a 32-inch 4K screen at 165Hz.

Best for

Buyers who want Mini LED backlight Samsung calls Quantum Matrix.

Skip if

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

Why we like it

The 1000R curve is steep for a 16:9 monitor, and its Quantum HDR2000 label is Samsung's own rating rather than a VESA tier. It reaches 2,000 nits peak with Quantum HDR 2000, and CoreSync lighting on the back matches on-screen colours. The 1000R curve fills your view.

It matches the Odyssey G7 37 on refresh rate (165Hz). On screen size it ties with the MPG 321CURX at 32 inches. Reaching 165Hz 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.

G-SYNC Compatible works on NVIDIA cards over DisplayPort, and FreeSync covers AMD cards. Its price falls between the Odyssey G7 37 and the MPG 321CURX, based on our last check. If refresh rate is your priority, the MPG 321CURX (240Hz) is the stronger choice.
