1440p at 240Hz is the sweet spot for fast gaming on a strong mid-range or high-end graphics card. OLED gives the best motion and contrast; IPS avoids burn-in and is cheaper.
We compared six monitors on panel, HDR, stand and overclock modes. Figures come from the makers' listings; we did not measure them.

The MAG 271QPX pairs a 240Hz QD-OLED panel with a height-adjustable stand.
Best for
- Most players who want OLED.
Skip if
- Worth skipping when oLED burn-in risk with static desktop elements is a problem.
Why we like it
It is the complete OLED option at this refresh rate. It matches the 27GX704A, the AW2723DF, the GO27Q24G and the H27E6S on screen size (27 inches). It shares a QD-OLED panel with the AG276QZD2; the H27E6S goes with a fast IPS panel.
You get an HDR 400 here, which sets it apart from the H27E6S and its an HDR400. A height adjustment stand is unique to it among these picks, while the H27E6S uses a swivel and pivot stand. To see 240Hz at 1440p, connect over DisplayPort or HDMI 2.1; older HDMI 2.0 ports cap the refresh rate lower.
Leave the maker's pixel-refresh routines enabled and hide static taskbars to limit burn-in risk. It was priced above the 27GX704A and below the AG276QZD2 at the time of writing.

How We Chose These 1440p 240Hz Monitors
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- How these picks were ranked
- We lined up six monitors on refresh rate, resolution, screen size and panel, using each maker's published specs. These are research figures, not bench results: 1 of 6 picks leave out HDR.
- The shared baseline
- All 6, from the MAG 271QPX to the H27E6S, state refresh rate, resolution and screen size and share 2560x1440 (1440p) resolution.
- Where the specs have gaps
- The GO27Q24G gives no HDR; the MAG 271QPX, the 27GX704A, the GO27Q24G and the AG276QZD2 give no color gamut.
- Price range
- At our last check the picks ran from the H27E6S ($150 to $250) to the AG276QZD2 ($250 to $500).
