Q&A

Q1. Why can’t my mouse pair with the 4K dongle?

Please check if your mouse model is compatible with 4K dongle. You need to download the latest VGN HUB version and upgrade the mouse firmware to the latest version to pair with the 4K dongle.

Q2. Why does my computer experience lag after setting a high polling rate or why can’t I achieve the calibrated polling rate with the test software ?

High polling rates require specific CPU performance and memory frequency. Computers with lower configurations may experience lag or fail to achieve the preset polling rate.

Q3. Why does my mouse's battery life appear to decrease after setting the polling rate to 4K?

Higher polling rate will increase the power consumption and shorten the life of the mouse, which is a normal phenomenon.

Q4. Can I continue to use the standard 2.4GHz dongle after pairing the 4K dongle?

After pairing the 4K dongle, the standard 2.4GHz dongle is disconnected from the mouse and cannot be used at the same time. If you want to switch back to using the 2.4GHz dongle, you need to re-pair it in the VGN HUB.
