4K needs a strong GPU for games, but it gives the sharpest desktop at this size. Every monitor here is 4K and measures 32 inches 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 panel, we say so.

Samsung's G81SF puts a 240Hz QD-OLED panel at 4K into a 32-inch screen.
Best for
- Buyers who want Glare Free coating Samsung lists as 54% less glossy than standard anti-reflection film.
Skip if
- Worth skipping when oLED burn-in risk with static desktop element is a problem.
Why we like it
Its Glare Free coating cuts reflections that glossy OLEDs show in bright rooms, and it detects logos and taskbars to dim them. It matches the PG32UCDM on refresh rate (240Hz). Like the PG32UCDM, it has a DisplayHDR True Black 400, while the Odyssey G7 37 uses a DisplayHDR 600.
It also offers a Glare Free coating Samsung lists as 54% less glossy than standard anti-reflection film and logo and taskbar detection to dim static elements. 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. Its price falls between the Odyssey G7 37 and the PG32UCDM, based on our last check.
