Picture is zoom out picture is to big for screen

Try grabbing your remote press the menu button go to picture and see if its on zoom insted of normal or stretch

Go to the picture setup of your settings menu.
Somewhere in there are options for selecting picture size.
The options will be similar to: Normal, Wide, Zoom, Stretch
You have probably selected Zoom, try Normal.

change the aspect ratio on the tv in the menu you have it set on zoom so the picture is zoomed in

you will need to move your projector closer to the screen. you will need to zoom all the way out and physically move your projector closer to the screen and then adjust your focus.

Sounds like your cable box is zoomed in, I run into this a lot when running service calls. On most cable provider's remotes there is an 'aspect' button next to or around the '0'. Try that and see if it helps you out at all :)

Get into setup for zoom function. Or, like my remote, the zoom fuction is right at the bottom with no menu to go to.

Try VIEW MODE button on the remote or ZOOM button on the remote from cable box.

You will have a button on the _original_ remote that says Format, Aspect Ratio, Zoom, Size or just AR. It will cycle through Normal, Stretch, Partial Zoom, Zoom, Gray Bar, or the like. You are not in Normal but in one of the Zooms. Stretch is used to make 4x3 movies fill a 16x9 screen, may not be desirable. Zoom is used to fill the 16x9 screen with movies that have been letter boxed. Gray Bar fills the sides of a 4x3 picture on a 16x9 set with gray to "avoid" burn in. Use normal except zoom on LB. -Ken

go into the customer menu and find either aspect or zoom setting and adjust to your taste

there may not be a zoom option but there should be a ratio setting i.e 16x9,4.3 letter box i had that problem and found it in my display settings my screen resolution was changed to 16x9 zoom
