My picture is now a lot smaller than the actual screen

Check actual on TV . Tv remote has either zoom, aspect ratio, or picture size button you can use to change view.

In the settings of the actual screensaver. You can click stretch to screen or actual size, Experiment with that.

your select button on your remote, then you just go to exspand.

I had this same problem I got a new cable box mine was outdated. However some channels still are smaller than the screen check different channels to see if they are all the same/small. the new cable box was called a MIDI box. My flatscreen was new when this happen it was the cable box not the tv

The IXUS 50 works with MMC and SD cards. Your new 4GB card is actually an SDHC card. While it fits into the slot, it is electronically incompatible and will not work. You need to use SD cards, 2GB and smaller.

The smaller picture is PNP called picture and picture.It can be set in to the menu setting.Go to menu setting and search the PNP code.Try to off or diable the PNP menu setting to back the normal single picture.

This function u can't do it without the tv original remote.Try website like Remotes.com to buy the tv original remote.Than used one of those buttons on the tv remote like View Modes,Picture Sizes,Aspect Ratio,Zooming to do the adjustment for tv screen pictures sizes.

There is a # button (hd zoom) on your Comcast remote that will adjust the picture size. Also make sure you are set to the proper resolution on the Comcast receiver (720p) and that the Dynex television is set to the proper input for high definition.

Hi,

You must reset the camera in the mainmenu to default.
