  • What does the button at the bottom of the Razer Viper V4 Pro do?

    The button is programmable on Synapse, but by default, it toggles power (press and hold for 2 seconds to ON/OFF) and DPI (press and release). The factory DPI settings are set at 400, 800, 1600 (default), 3200, and 6400.

  • How do I test the Razer Viper V4 Pro’s polling rate?

  • How do I optimize my mouse for the best accuracy in gaming?

    To improve accuracy, consider disabling the "Enhance pointer precision" option in your Windows mouse settings, as this feature can affect mouse sensitivity. Additionally, you can further optimize performance using the Razer Synapse app. Learn more about our enhanced DPI features.

  • What do the 3 LED indicators on my Razer HyperSpeed Wireless Gen-2 dongle show?

    From left to right, they indicate battery life, connection status and polling rate by default. However, you can configure each LED via Synapse to indicate battery level, connection status, polling rate, or DPI stages in any order you prefer, or switch it off.
