This is a great HDMI cable I brought. I ordered it from Monoprice and received it 3 days later. You can't beat the price or delivery time from Monoprice.
Sometimes You Need a Powered Switch for a Long Cable Run, or Even an HDMI Extender
I bought these 8K cables for use with a 4K monitor shared between 2 PCs. One PC has a 3 foot 8K cable attached to a 4K switch; the other PC has a 10 foot 8K cable attached to the 4K switch. The switch outputs via a 1.5 foot cable to the monitor.
Was experiencing random screen blanking using a cheap unpowered 4K switch on the PC with the longer cable run - the other PC was OK. After changing out the cheap 4K switch to a better powered 4K switch, hte screen blanking problem disappeared.
So the cables were fine; it was the cheap switch causing the problem.
