I suggest you try a UPS (uninterruptible power supply) on one setup: plug the source and display into the UPS and see if that resolves the issue: if it does it would confirm you have a power problem
if not, try the other suggestions Ratman offered: please let us know how you make out
Unfortunately, I do not have a UPS to test with. I've been wanting one for my PC for a long time but I simply cannot afford it. Are there any other ways I can test the power? Also, what UPS do you recommend I try with the PS4? It obviously needs to powerful enough to support the console, but I don't know what the PS4 would require. My parents have a UPS for their PC and I may be able to borrow it for a while to test this issue, as long as it's powerful enough.
I do have a really old house, so perhaps power is the issue after all. I just need to find a reasonable way of testing it.
As for Ratman's "suggestions", I don't find his post very helpful. "The source device"... "The TV/Monitor"... What am I supposed to do with that information? I suppose poor cables could possibly be an issue, but over time I've tried multiple cables and the problem existed with all of them. I also don't have anything between the source devices and the displays. They all use a direct HDMI connection.
At any rate, I still appreciate any help I can get.
Also I was just thinking... if there is an issue with the power at my house, why is it that the only thing I've noticed being affected is HDMI?
