I recently purchased an HDMI to DVI cable to plug my HP Pavillion 9000t into my plasma TV. Once I figured out the Function+F4 thing, it was great . The picture is very clear (once the resolution was lowered), but there are blinks in the picture. The screen goes black for a split second and then is back on. It doesn't happen constantly, but I watched a DVD from my laptop on the plasma screen and it got quite annoying. Any ideas what could be causing this? Anyone had similar problems?
