I got tired of having my HTPC in the front room, so I picked a nearby closet - 20ft of cable- to put it in. I first tried a 12m piece of hdmi signal didn't get there. It would show the everything, but after the windows splash screen nothing and the TV would say looking for signal. I talked to some people and they told me that the gt 220 graphics card in my htpc didn't put that much voltage out on the hdmi. I decided to run HDMI over ethernet. the first adapter I got was unpowered, I got no signal at all. I figured that maybe the voltage wasn't enough to go through the ethernet either. I got a powered HDMI over ethernet and I though it was going to work, and it does to a point. I can see the POST screen, the splash screen, but after that no signal. Should I replace the video card? with what?
