So I recently built a llano based HTPC (A8-3850 CPU on ASUS F1A75V EVO Mobo).
After several days of thinking my new Onkyo receiver was to blame for a display issue, I have now removed it from the setup and isolated the problem to either the HTPC or the (also new) Vizio TV.
What happens is this: If the TV has been off for more than about 20-30 minutes, when it turns back on there is a flickering of the screen. This flickering is a distortion of the image akin to a loose analog cable connection. It can start off very strong, distorting the entire screen or it can begin just as a few flickering random lines. The issue will persist from anywhere from 20-120 seconds, lessening in intensity and duration until it completely disappears. The screen then remains normal for the duration of the viewing session and only will reoccur the next time the TV has been powered off for an appropriate amount of time.
While I am not completely convinced that it is the PC at fault, tests would seem to indicate this (more on that below). I am wondering if anyone else has experienced issues like this with Catalyst drivers, chipsets, or ASUS Mobos?
I am trying to obtain some additional input sources to isolate this to the PC or the display. However the following tests point to the fact that it is not just the PC, but the Catalyst drivers specifically:
Test 1: My TV has built in Apps (like Netflix). Additionally, when bringing up the on-screen menu, it minimizes the current display to the right of the screen, so that you are able to see both the menu and the PC output. When the flickering occurs and I bring up the menu, I am able to see the flickering on the minimized image, but not on the TV display as a whole. Furthermore, if I pull up the internal Netflix App, there is no flickering at all (i.e. the flickering from the PC output is not present). This would seem to indicate that the TV display itself it not undergoing any disturbance, but rather just the output from the PC.
Test 2: If I enter the BIOS of the PC (UEFI BIOS, so fairly graphical) and perform my TV sleep on/off tests with the BIOS screen up, then the flicker does not seem to happen. However once I boot into Windows and the Catalyst drivers take over the tests will once again produce the flicker.
I would appreciate any additional advice for troubleshooting, or notification of problems similar to this that people are aware of. I am hoping that if indeed the HTPC is the problem, that the issue is Motherboard related and that I won't experience similar problems with Catalyst drivers on another system.
Thank you!
