Logitech ERGO M575 – Specification, Price and Review

At 125 Hz (Logi Bolt), 88-133 Hz (Bluetooth), the mouse sends its position to your PC every 0.125 milliseconds — that's 8,000 times per second. The practical benefit is smoother cursor motion on high-refresh-rate monitors (240Hz+) and fractionally lower click-to-response time. In blind tests, most players can't reliably distinguish 4000 Hz from 8000 Hz, but the ultra-smooth feel is perceptible when tracking moving targets at high sensitivity.

At 125 Hz (Logi Bolt), 88-133 Hz (Bluetooth) polling, the wireless latency of this mouse is effectively indistinguishable from a wired connection in real-world gameplay. Modern 2.4 GHz wireless gaming mice use dedicated dongles on low-interference USB channels and achieve round-trip latencies under 1–2ms — well within human perception thresholds. Professional players use wireless mice in tournaments regularly. The only scenarios where wired has a concrete advantage: environments with heavy 2.4 GHz interference (crowded Wi-Fi, poorly shielded USB hubs nearby), or if you simply never want to think about charging.

This mouse is designed for 2020 grip.

Despite the high DPI ceiling of 380 – 4,000 (adjustable), most serious gamers use 400–1600 DPI. The "right" DPI depends on your mousepad size, monitor resolution, and game sensitivity settings. A useful starting point: aim for an in-game effective sensitivity that requires your full arm to move the mouse ~30–40cm for a 180° turn. This gives you precision for micro-adjustments while still allowing full rotations. Start at 800 DPI and adjust from there. High DPI (3200+) is useful mainly for very small mousepads or navigating large multi-monitor setups outside of games.
