I'm thinking of buying a 17" MBP, and I'm wondering about connecting it to an HDTV. I know that I can connect the MBP to an HDTV via an adapter (display port to HDMI), and then mirror the MBP display on the TV. But the native resolution of the 17" MBP screen is 1920x1200, while the HDTV native resolution is 1920x1080. So if I mirror the display, will the TV get a 1920x1200 signal? What will happen to the extra 120 lines (1200 vs. 1080)? Will the image on the TV be cropped somehow? Or squashed to fit in the extra lines?
