12 min read5 products evaluated
240Hz is the line where motion starts to look noticeably smoother for this kind of setup. Every monitor here refreshes at 240Hz or more, is 4K and uses a QD-OLED panel, ordered from the lowest price.
The order reflects refresh rate, resolution and size from maker specifications; a missing response is flagged, not filled in rather than guess, since we have not benched them.

Alienware AW2725Q 4K QD-OLED on Amazon (opens in a new tab)
Alienware's AW2725Q is a 26.7-inch 4K QD-OLED at 240Hz with USB-C and a height, tilt, swivel and pivot stand.
Best for
- Keeping the budget tight.
Skip if
- Pass on it if oLED burn-in risk with static desktop element rules it out for your setup.
Why we like it
It has one of the most adjustable stands among the OLED models here. On screen size it trails the group at 26.7 inches, while the PG32UCDM comes in at 32 inches. Like the MPG 321URX and PG32UCDM, it has a DisplayHDR True Black 400, while the Odyssey OLED G8 G80SH uses a DisplayHDR True Black 500.
You also get 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. It undercut the MO27U2 and every other pick on price at the time of writing.

What to Look for in a 240Hz QD-OLED 4K Monitor
Key buying criteria so you get the right fit the first time.
How much screen size you need
Here screen size runs from 26.7 inches on the AW2725Q to 32 inches on the PG32UCDM. Start with the PG32UCDM if screen size decides it.
Extras that separate them
The MPG 321URX: HDMI 2.1 and DisplayPort 1.4a inputs. The PG32UCDM: 90W USB-C power delivery. The Odyssey OLED G8 G80SH: USB-C with up to 98W.
Budget
$500 to $1000 buys the AW2725Q, the MO27U2, the MPG 321URX and the PG32UCDM; $1000 to $1500 buys the Odyssey OLED G8 G80SH at our last check.
Start from what matters most
Keeping the budget tight: the AW2725Q. Buyers for whom price is not the deciding factor: the Odyssey OLED G8 G80SH.
Pick the panel type
IPS offers wide viewing angles and good colour. VA has higher contrast but slower dark transitions. OLED has perfect blacks and very fast response but carries a burn-in risk with static content.
