I want to run 2 displays at the same time on my laptop. I have a laptop with a 645m gpu, which is supposed to support up to 4 displays, however I cannot display more than 2 at any given time. I am using one through HDMI, and the other through DPI, and my laptop screen itself. Both are recognized, in the display settings I can easily change between the 3, but it will not let me use them all together at once. With any spread between them, be it 2 on mirror, one on extend, one will not receive signal. Any ideas as to what I can do to fix this issue? Is it a gpu issue?
