I'm having the same issue with the same GPU and similar desktop computer.
Monitor: Philips 243V5 DVI
Motherboard: ASUS h110m
CPU intel I5 6400, 2,70GH
the rest of the features are equivalent to OP's
Since updating to Radeon software version 18.5.1, I don't see static when waking the computer. I'm curious if this is the case for others who have this issue.
