PC to TV via HDMI = no picture when idle for a while
Right, perhaps a poor title, but this has confused me.
We have a Dell Vostro connected to a Sony Bravia TV via a HDMI cable, using an 512MB ATI Radeon HD 4350 Low Profile card.
On the surface of things this seems to work fine, however, when the PC is left idle for a while it seems the signal between PC and tv is lost, no amount of key presses or mouse clicks seems to bring it back to life, only hard restarting brings it back on the screen.
It's on our domain, which has a high performance power plan set to turn display off never, it doesn't have a screen saver either. I had a look in the ATI Control center, nothing jumped out at me.
The keyboard and mouse are both wireless (Logitech MX3200 Cordless Keyboard and Laser Mouse - Leading edge design, one-touch media controls).
Does anyone have any ideas?
