Frequently Asked Questions
Is the Logitech G703 wireless or wired?
Both. It runs on LIGHTSPEED wireless with a USB transceiver, and you can plug in the included data and charging cable to switch to wired mode mid-game without interrupting play.
What DPI range does the G703 support?
The PMW3366 optical sensor covers 200 to 12,000 DPI, with no smoothing, filtering, or acceleration applied anywhere in that range.
How much does the Logitech G703 weigh?
107 grams. The body is ergonomically shaped with rubber grips on the left and right sides for added control during long sessions.

Six programmable buttons, configured through Logitech Gaming Software into click and keystroke sequences. The software requires Windows 7 or later, macOS 10.11 or later, or Chrome OS.
