I have sa4250hdc with comcast and many hd channels have a 1/4" gap at top and even smaller gap at the side. I can zoom in and fill these gap but at normal pic size channels dont fill the entire screen. My other TV with SA8300hd box works fine. do I need to change the box? Anyone experience anything similar?

thanks!

What is the TV this is connected to?
How is it connected?
What channels are giving this problem?

TV is Samsung FP T5884 and is connected via HDMI. almost all hd channels having issues. I have 2 HD boxes at home and tried both but same results.
thanks

comcast rep has no clue how to help. They want me to stretch the picture to correct the problem... :mad:

thanksIf you've tried 2 HD boxes, and both do the same thing, would make me suspicious of the Sammy.

yes! I found that both HDMI1 and HDMI2 ports are causing this problem. I tried HDMI3 and everything works fine! thanks for your help!
