Thanks for this. I wouldn't have even thought to try that. I tried it on my current adapter, and it's still doing the same thing. Also for reference, below are the 2 cables I tried previously which are very similar to the one richwest3 is using. I'm starting to wonder if my V30 that is messed up somehow because surely these cables are not the issue.

If that's the case, then you get to play musical cables trying to find something that works. HDMI is like that.
I've had luck with these...
