Hi guys, i just received my ATI Dvi to HDTV adapter today. I plugged it in and it all worked fine, but I had overscan issues. So I was messing around with Powerstrip. Then I went to control panel, settings, displays, and click on the hdtv where u can set the timing, i switched from 480i to 720p. But then the whole screen flickering and i co uldn't see anything. so i had to reset my computer, but after the window boot up screen, there's no display on my hdtv anymore. i tried to reset it via the disp switch on the ati dongle , but it didn't help. So how do I reset the dongle? thanks.
