If so there is a NEW thing Adobe has done and that is to add hardware acceleration. We are seeing lots of posts about it, so if this is a FLASH VIDEO, please turn this feature off.
Here's a discussion how to do that -> http://forums.cnet.com/7726-6122_102-5104329.html?tag=posts;msg5104329
A friend is having a display problem -- every 20 seconds, the screen goes blank, then it reverts to very low res (like CGI), then a few seconds later returns to usual high-res. The OS is Windows XP. She said it began when she was attaching a video to an email.
A wild guess is that some video software is trying to change the screen resolution, stuck in a loop.
I've never seen this before and don't know where to start. An idea is to go to task manager and to try halting all active processes one at a time, but that's very slow.
There's nothing special about the monitor; it seems to accept standard resolutions from roughly 600x400 to around 1400x1000 (these numbers aren't exact). There are no power-saving options in effect, and the screen-saver is timed to begin only after 30 mins. of inactivity.
Any suggestions as to diagnosis or how to approach the problem would be appreciated. Thanks.
