Just fyi, I traded the 1050 ti for an amd rx 550 and the problem with tightvnc is gone. Also, I found my board does not allow overclocking of my i7-4790k but it does run 4 ghz out of the box, so I'm fine with it.

This card also makes some noise in my audio, sort of a whoosh, whoosh, sound, that seems to go with the gpu (the 1050ti also did this). It's not a showstopper though.
