Hey all, I have a Lenovo ThinkPad Edge E420 (1141BTU) and a Sony Bravia LCD television. I bought an HDMI cable and used it a couple of days, and it worked great, I just plugged it in and it immediately recognized the tv and displayed what I had on my laptop. When I was trying to disconnect it the second time, I had to adjust some settings to get the display back on my computer but cannot remember the specific steps I did. Now it won't display anything. I have tried multiple different ports, re installed video drivers, and tried to fidget around with projector settings and couldn't get the fn+f7 button to work. Any help would be greatly appreciated, I don't think its the television or the cable.
