The Best 4K 240Hz Gaming Monitors
From the AW2725Q to the 32GS95UE: four monitors ranked on refresh rate and screen size, with who should skip each one.
By The PC Journal editorial team
11 min read4 products evaluated
A 240Hz panel only pays off when your GPU can hold frame rates near that figure. Every monitor here refreshes at 240Hz or more, is 4K and refreshes at 120Hz or more, ordered from the lowest price.
Our comparison rests on published figures for refresh rate, resolution and size; nothing here was tested in-house, and where a maker leaves out HDR, we say so.

Best for
- Keeping the budget tight.
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. Its 26.7 inches screen size is the smallest in this group; the 32GS95UE leads at 32 inches. It shares a QD-OLED panel with the MO27U2 and MPG 321URX; the 32GS95UE goes with an OLED panel.
It also comes with 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. No other pick here cost less at our last price check, and the MO27U2 was closest.

- All 4, from the AW2725Q to the 32GS95UE, state refresh rate, resolution and screen size and share 3840x2160 (4K) resolution and 0.03ms response.
- Where the specs have gaps
- The MO27U2 gives no HDR; the MPG 321URX and the 32GS95UE give no color gamut.
- Price range
- At our last check the picks ran from the AW2725Q ($500 to $1000) to the 32GS95UE ($1000 to $1500).
