Fix VirtualMatrixPanel scan rates

Browse source 
New PR to include changes made by #305 

Fixes #286 and related single display issues

I tried to avoid "fixing" the formatting but it was all over the place so I had to ;)

Would be great if we could get some QC tests, especially for single display VirtualMatrixPanel usage.
