I have an Asus UL50V with Windows 7 and Intel 4 series chipset family display adapter. When I connect it via HDMI to the Smasung TV it says No signal on the screen. The HDMI works fine when connected from the cable box to the TV. Also, I tried connecting my Asus to a friends TV via HDMI and it worked fine. So there is no problem with the HDMI cable or my computer, the problem is in how my computer communicates with this Samsung TV via HDMI.
