I have a problem with a HDMI connection to 3 TV’s.
I have installed 2 Cat6 cables of about 130 to 150 feet to each TV.
I installed a HDMI converter from HDMI to 2 Cat6 to each TV and connected to a 1 to 4 splitter connected to a laptop.
The laptop is setup to have the HDMI as an extended Monitor.
The problem is that the TV’s blinks on and off every 5 to 10 minutes not all at once, one blinks more frequent than the others.
If I connect a different laptop it does not blink. Both laptop OS is Window 7
My question is, can the HDMI port on laptops vary output capacity or does the extended monitor of the HDMI configuration be configured differently.
