Sides and top cut off on my 1080i TV

[markperez]

Watching the election coverage and they have all the graphic data on the sides and at the top. On my 1080i 56" TV the sides and top are partly cut off but if I watch my 720p 24" TV the graphics seem well placed. Anyone know what might be the issue?

BTW the 720p is a LCD and the 1080i is a rear projection.

Thanks

Check the 'format' set up on your projection TV. Mine has several options, but 1080i on the STB expects 16:9 standard. If you are set to stretch, zoom, or something else on the TV, parts of the picture will be cutoff

It sounds like your 1080i TV has an unusually large amount of overscan.  Overscan is the part of the screen that your TV cuts off.

Plasmas and LCDs typically have relatively low overscan (between 0% and 6% total cut per dimension), while older CRT projection displays can have closer to 10% overscan.  You should make sure you are in 1080i mode on your 56" TV.

well I figured out that I had to go into the secret service menu and adjust things that a tech should do. Basically if there are people old enough to remember when you have adjust the vertical and horizontal of the picture to get it to fit on CRT tubes. That is what I had to do. Of course the menu was written in tech speak and I didnt have the service manual at the time so I stupidly played with settings I should have and didn't write down the orginial settings so I goofed it up even more. Took me till this morning to get it some what close to the original.
