Hello Razer Support / Community,
I have a Razer Viper V3 Pro (Serial Number: PM2513H32100089, EU Packaging).
In Razer Synapse (latest version), in the Calibration tab:
- I have enabled the checkbox "Enable Asymmetric Cut-Off".
- But the two sliders are NOT independent:
- When I try to move the lower slider (Landing Distance), the upper slider (Lift-off Distance) moves with it automatically.
- If I move the upper slider, the lower one jumps to be 1 unit lower or follows it.
- I cannot set different values (for example: lowest Lift-off and Landing on 13) to fix cursor jitter / spazzing / skipping pixels when lifting the mouse and placing it back down quickly.
I have already tried:
- Reset Surface Calibration in Synapse.
- Hardware reset of the mouse (hold left + right buttons + scroll wheel for 7-10 seconds while powered off).
- Full clean reinstall of Synapse (uninstall, delete leftover folders, reinstall from official site, restart PC).
- Update mouse firmware via Synapse.
- Multiple PC restarts.
Still the sliders stay linked or stuck together. Because of this I cannot properly set LOD — with low lift-off I get bad sensor behavior (cursor spazzes or skips) on landing.
Also on mysupport.razer.com the Chat button is grayed out / not clickable, so live chat is not available.
Is this a known bug in Synapse for Viper V3 Pro?
Is there a workaround, update or specific steps to make the sliders move independently?
Or does this require replacement / RMA?
Thank you for any help or advice!
