MSI MAG 275CQDF X24 27" 240Hz/400Hz dual-mode gaming monitor

27-inch Rapid VA dual-mode monitor

The MSI MAG 275CQDF X24 is a 27-inch curved gaming monitor built on a Rapid VA panel with a 1500R radius. It targets competitive players who want the flexibility to switch between 2560 x 1440 resolution at 240Hz and a lower resolution at 400Hz for faster motion. Adaptive Sync keeps the display in step with the GPU for tear-free output. The non-glare matte black cabinet reduces reflections during long sessions.

Thermal noise and power profile

The unit runs on a standard external power supply and produces no audible fan noise because the design is entirely passive. Typical power draw stays within the limits of a conventional desktop monitor, so it adds little heat to a small room. The 300 cd/m² peak brightness and 5000:1 contrast ratio are achieved without active cooling. Surface temperature remains comfortable to the touch after extended use.

Dual-mode switching and eye-care software

Dual-mode lets the user toggle between 240Hz at 2560 x 1440 and 400Hz at a reduced resolution through the on-screen menu, matching the refresh rate to the game genre. The 0.5 ms GtG response time minimises ghosting in fast scenes. MSI’s Less Blue Light software mode, certified by TÜV Rheinland, shifts the colour balance to reduce short-wavelength output for more comfortable late-night viewing. An integrated earphone output provides a convenient analogue audio tap.
