Is it the resolution of your laptop monitor? Or spacedesk display?
If it’s spacedesk display, you have to enable the custom resolution in the viewer settings and select from the resolution list before connecting the spacedesk.
The resolution set is 1024×768, which is extremely zoomed in and does not look very nice. However, when I go to change the resolution, the box is grayed out and will not let me click on it. Is there any way to fix this issue?
