Hi,
Thanks for all the advice, but it's still the same.
- The ground is not an issue.
- The UPS is not an issue.
- The Dells are not an issue.
- The TV is not an issue.
- I also checked the other electronic devices in the adjacent "computer room"
So, I re-organized the AV cabinet and moved the cable box around. I found a better spot, I'll monitor this for a while and see if it stays like this or if the problem returns.
Thanks,
VidTron.
