I have trouble with the HDMI over cat5 system running on the 1000 watt Xantrex MSW inverter? It works perfectly on Gen or shore power but when I switch to the inverter the TV kicks out intermittently. If I run an HDMI cable directly from my Sat receiver to the TV no problems! I am of the opinion that the HDMI transceiver does not like Mod Sine Wave Power. Anyone else with this problem?
 
I'm not surprised, the MSW waveform contains a lot of noise in the form of harmonics that can interfere with the low power digital signal on the Cat5 cable.
 
An update: Kind of an expensive cure but all is well after replacing the 1000W MSW inverter with a 2000W PSW inverter. Also my electric clock no longer gains 20 minutes over night.
 
And you wondered why you were waking up on time but cranky.....
