M17x-R3, HDMI IN problem when connecting cable box to laptop

Hi,

When I connect my cable box via HDMI to my M17X and reboot the laptop, I can see the TV perfectly fine. If I disable the HDMI IN (F8), I have my log in screen. Once logged in, if I re-enable the HDMI In, I can see for 2 seconds the TV, then the screen goes black. My cable box recognized that it is connected to M17x-R3 laptop, the setting are the same on both the cable box and laptop, same resolution, same 60Hrz, I have tried with interlaced and not, but nothing work. I can only see the TV if I reboot the laptop and it stays at the log in prompt. Can any one help?

Thank you.

It's likely your Driver version.  If you have a Driver version newer than the one listed on Dell's support site for your m17x, you will experience this issue.  I had the same thing happen when I updated to a newer driver from Nvidia, but after installing the driver found on Dell's site, the problem was fixed.
