Are you connected to a box? If so, switch the TV aspect ratio settings to 16x9 and then adjust the cable box output resolution and aspect settings.
The INFO bar that notes the resolution and Hz. is normal - it's the TV telling you what signal is being detected, and this is normal.
Does that help?
I have a Samsung 26? LCD TV and recently upgraded to HDTV via comcast.net.
My screen display overlaps screen edges, i.e. there is image cutout on all sides. I cannot shrink size of screen display so I see 100% of display. I tried remote control P.SIZE button. Best setting is ?Screen Fit? but there?s still image cutoff.
On boot-up I get flash display: - ?HDM1/DV1 - No Time Information (1280 x 720 @ 60Hz).?
I don?t recall this issue before upgrading to HDTV, but Comcast says it is not their problem. What to do?
