Thanks for the help!
Actually, my laptop has a DVI-out port. I was doing some research, but I'm still not sure how this all works. Please let me know if this is correct:
My understanding is that I can connect my laptop to the HDTV via a DVI-HDMI cable. Will I then be able to watch, say Star Wars III in HD format? Also, how will the graphics look if I play games on the TV? The resolution is 1366 x 768 and the aspect ratio is 16:9.
Thanks again for the help!
