Ati radeon 5570 hdmi tv help

[digger933]

Hello,
I recently bought a new computer with an ati radeon 5570 card in it. As a monitor I am using a 32" lcd tv by HDMI. Whenever i turn on the computer i get a black screen but eventually it pops up. but the real problem is, whenever the computer goes into sleep mode or switch to a different mode on the tv...whenever i go back there is no display and i have to restart the computer to get display again... please help

I am having the same issue with a 42" Vizio LCD TV. This was supposed to be a home theater PC, but that's hard to do when turning the TV off causes the HDMI signal to be lost. The only way to get it back is to shut down and boot up again.
