Sure, I could use remote control, but I've found that screen sharing apps eat a little bit of hashing power when you're connected.
I was surprised at how much of a hit to hashrate teamviewer causes, even on a Ryzen 5 1600, and a KVM switch isn't a good choice for me at the moment because the Onda 6-GPU boards have a VGA port while everything else I have shanghaied into mining uses DVI/HDMI/DP (though I guess I could get a bunch of DVI to VGA converter plugs).
If you use CPU's that have built in GPU, and set that as primary, Teamviewer will not make any impact at all on mining.
