External monitor blinks/flickers
Hi all!
I have no idea what happened, but my external display started flickering. It gets dark for about a second or two and it displays contents for a fraction of a second, going dark again. Also, the display is covered with dancing static-like colourful dots when it stabilises for a few seconds (rare). Sometimes it even enters the power saving mode. The monitor is completely useless. Playing around, I discovered that the effect disappears when I'm using 800x600 or 1024x768 resolution. With such low res, display works fine, but since it's a 1920x1080 screen... it's hardly any point in keeping it on the low.
I have a macbook running win7-64, connection is VGA with minidisplay port adapter. Since low res works, it can't be the cables nor the adapter.
No system restore point. Latest drivers, etc... what might be wrong and how could I fix it?
Edit: Plugging the laptop power cord doesn't help.
