I have a problem with my HTPC video signal. The connection goes like this:
ATI Radeon x600 DVI output --> MonoPrice 3x1 HDMI Switch --> Panasonic Plasma
From the video card to the switch, I'm using a DVI to DVI cable with a DVI to HDMI adapter at the switch end. From the switch to the TV I'm using an HDMI to HDMI cable.
I'm also switching a Denon DVD player and Dish Network DVR through the the MonoPrice HDMI switch, and they have no problems.
In general, the PC works OK -- I can use the TV as a monitor, watch DVDs, etc. However, sometimes when I turn on the TV and select the PC as the input, I will get no picture from the PC. I have to go to another PC in the house to remotely shutdown the HTPC. Once it comes back on, everything is fine between the PC and the TV. All connections are good, proper inputs are selected, etc. It's just that after a while (I don't know what "a while" really is
, but let's just say a few hours).
If everything is working, I am
able to switch between the Dish Network signal and the PC, so it's not just a matter of switching to a different input and not being able to go back to the PC.
Any ideas? I'm not an HDMI/DVI expert, so I'm not sure what the problem is. I think there's some handshaking going on at each connection point, so I'm not sure what the point of failure is. Is it the PC, the switch or the TV?
I've ordered a new HDMI video card, as recommended here
. The ATI I have now has been problematic, and ATI drivers are the worst I've seen. I've heard good things about the GeForce stuff, so hopefully it will help. It should arrive today or tomorrow.
So, any ideas on what could be the problem?
