I have just bought a refurbished laptop a few days ago. The problem is that when I connect the HDMI to DVI to my monitor (HP 2009m) the image looks green and flicker. I have also tried conecting an HDMI cable to two TVs and they don't get any signal. At least in my monitor I can see something.

Intel HD Graphics 5500
