I have a Panasonic Plasma TV. The Radeon HD 6450 is directly hooked by HDMI to that. When I have switched on both the system and TV at the very first time, there was no problem. But after the TV switched and again switched on, it gives me some trouble. Also, Windows is not able to find any audio device. I have to restart the computer to run the WMC. I am sure about that all latest drivers are installed. If anybody knows the solution for this problem, please let me know.
Thanks in advance.
Problem with Panasonic TV and Radeon HD 6450
Seems to me that there is something wrong with your HDMI. have you tried changing the wire? If not then buy a good cable from the market and try connecting with it.
If your TV has more than 1 HDMI, try connecting it to the other one which you haven't tried.
Download the latest catalyst software. The catalyst is not updated when you update the drivers. You have to download it manually.
Unplug your Card from the computer, blow it off with a blower, maybe there is a lot of dust on it and it is causing the issue.
Try to see if there is a software or a game that is causing this issue. There might be something inside the PC that is not letting to use the external display.
