At the video cable, no. Both sides assume the other side can short to ground or spike or whatever. This is basic circuit protection that you don’t trust the other side.
At the power though, I guess if you shorted the high voltage long enough to pop the breaker and the computer was on the same breaker sure. But this would be tough to do for enough time to pop the breaker I think.

Unfortunately, this still leaves the software side. I've had computers freeze or crash on me when plugging / unplugging an external monitor, and even one recent case of the EMI generated by the gas piston in my office chair regularly causing my work laptop to bluescreen when there was an external monitor plugged in (with HDMI cable acting as an antenna). This tells me that it's quite possible thar shooting a monitor would cause the computer to freeze or reboot itself.
