Hi @petresarr,
Current spacedesk only support 30Hz or 60Hz refresh rate.
On spacedesk Android Viewer app’s Settings -> Quality/Performance -> Custom FPS rate, you can only select 30FPS or 60FPS and it will correspond to the display’s refresh rate.
As of now, we have no plans to support more than 60Hz.
We set the max to 60Hz to limit the network bandwidth to prevent latency.
