How do I connect my laptop to my cable box with an hdmi cord?
My Sony VAIO laptop has an hdmi output, I have the cable, and plug it into the comcast cable box hdmi port. However, I still can’t seem to get my laptop screen to display on my tv. How do I do this?

The hdmi output from your laptop only works for playing movies out, not screen splitting.
If you have a BluRay player in your Sony, the output from your laptop should go directly to the tv, not to your cable box.
There should be another video out on the Sony for showing your screen on a projector (PowerPoint presentations and the like).
Also this from AfterDawn forums:
PowerDVD only displays HD content on the primary display. You have to make your HDTV the primary display. HD content is the only type that is affected in this manner. Thank Microsoft and the HD DRM overlords.
So your laptop screen will be black while playing an HD movie out to tv.
The HDMI on your laptop is an “output” and the HDMI on your cable box is an “output”. To use your HDTV as a monitor for your laptop, you would need to connect an HDMI cable directly from the laptop to the TV.
