“Why do I lose signal on TV when 1 or other is turned off? I have a cable box and splitting the output of that to two 1080p TVs. If both are on, it works just fine, but as soon as one or the other tv is turned off, I lose signal to the tv left on. One tv is 60hz and other is 120hz. If I power all devices off and let cable box boot back up, will it resolve the issue or is this a known flaw in the this switch? I should be able to turn either tv off and not lose the signal/picture on the other.”

The issue here is that the device is a "splitter," not a "switch." It has a logic circuit inside that doesn't allow only one output at a time. In the olden days of analog A/V connections, the signal connections between devices were mono-directional, they only sent a signal one direction (from source to output device). In this new - fangled digital age of A/V connections, the source and output devices communicate with each other bi-directionally. Basically this means all devices must be powered up for operation before the splitter will function. I hope this helps!
Sorry, there was a problem. Please try again later.It is not a flaw with the switch. It's actually part of the HDMI signal that causes this. The HDCP built into the cable causes the signal to stop going to both TV's when you turn off one.
