My computer is a alienware alpha with i7 processor and 2gb of video memory and with one hdmi port i can connect 1 monitor. and i have also purchased a usb 3.0 to hdmi 1080p adapter called mini hd. And it was working like 24 hours ago until i reset my pc by reinstalling windows. and it wont connect the usb to hdmi plugs the usb into my computer then i have a vga to hdmi coming of that then the vga cable goes into the monitor and yes the monitor is turned on and i don't know why because it was literally working today before i reset my computer. maybe i need to update my driver but i cant find a reliable program for free. ALSO i can change the two hdmi so i can use my second monitor but the other one wont work.
