Violet wireless mouse for competitive play

The MSI FORGE GM340 in Violet weighs 57g and connects through 2.4 GHz wireless, Bluetooth 5.2 or USB 2.0. A PixArt PAW3311 sensor provides six DPI steps from 800 to 12000. Six buttons and a symmetrical shape suit claw, palm or fingertip grips for long sessions.

Tri-mode connectivity limits

The 2.4 GHz link runs at 1000 Hz with 1 ms report rate, while Bluetooth 5.2 and wired USB 2.0 operate at lower polling speeds. Wireless range and stability depend on local RF noise and the host adapter. USB 2.0 bandwidth caps data throughput compared to newer standards.

82-hour battery and 50-million-click switches

A full charge delivers up to 82 hours of continuous use at default lighting. The main switches are rated for 50 million clicks, giving years of daily gaming. At 12000 DPI the sensor remains accurate, though very high sensitivities amplify micro-jitter on some surfaces.
