I have a Helix 2 with the ultrabook pro keyboard. I want to hook up an extra monitor for home use but every monitor that I hook up the max resolution is only 640x480. I've tried 2 different monitor, 2 different video converters, 2 different VGA cables and 2 different DVI cables. Every combination results in the same 640x480 resolution. I'm assuming that the problem lies within the the mini DP driver? How can I get a better resolution?
