I figured out why my second monitor was glitching out (it did it again last night, couldn't get a signal through the Dvi-HDMI-Mini-HDMI cable-converter combo, same again this morning). The HDMI-MiniHDMI converter is buggered I guess. The mini-hdmi part is... slightly wobbly so I guess it broke or some crap. Luckily I have a second one that seems much sturdier. I still don't exactly like how it... dangles from the card as it's quite heavy?? but it seems more secure this time. I hope. :|
