7D Slideshow Image Size

when connecting the 7d to a television using the RCA connectors that came with the camera, the slideshow images on the tv screen are small; they don't take up the entire screen. The images are set as if in the Playback display mode with a histogram.

I've gone through the manual and tried several settings, but no luck enlarging the slideshow image size. I even played a movie recorded in full 1080 24p and it also plays back in a small screen.

thanks for any assistance.

This is not a direct answer to your question but I can view full screen image from my 50D when using HDMI cable connection.

I've only used HDMI so far, but that came out full screen. You have the correct TV type setting in the camera? You have the camera playback set to go without the histogram?

RCA connectors are for the old low res video signal 480 lines. The 1080 HDTV has 1020 lines of resolution, so 480 lines only fills 47% of the vertical; a 720 HDTV has 720 lines of resolution, so 480 lines fills 67% of the vertical...unless the TV itself internally fills a larger vertical with the lower res signal that is coming in.

well, after considering the two responses, it seems that whatever Display mode is used during Playback will be used for the Slideshow/Movie playback. So, for me, when I take stills, I have the display with the histogram shown; hence, not full screen when connected to the tv. Simply pressed the Info button to get full screen (before going to the Slideshow menu).

This probably falls into the "Duh" category. Thanks.

Wilt, it will adjust to the TV. It's not the same signal sent out via the HDMI interface as thru the normal video output.

I know that HDMI is higher resolution output...the RCA connectors which the OP referenced are a very old, TV composite video signal connector that is limited to 480 lines, and it was not even good enough to carry 480 lines of SVHS signal!

The RCA out is regular ole video (you get to choose NTSC vs PAL in the menus somewhere) and indeed it gets whatever info would have gone to the LCD.

Well, it's not the connector that limits the vertical resolution to 480 lines, it's the rather low spec American TV system that imposes that limit.
You can use the same connector on a European system and get 625 lines, for example.

S-VHS was by definition a Y-C signal that needed two shielded conductors, so that's why the RCA single one didn't work. The single RCA could, however, carry a picture of >640x480. The NTSC system has(d) 525 scan lines (480 visible) (yes VHS and S-VHS both had 480 scan lines) while PAL is 625 scan lines (576 visible) - an improvement in number of scan lines and color reproduction. Just for clarity, those numbers are all scan lines, not lines of resolution - if you want to call them resolution you need to add vertical before the word. 1080 has 1080 scan lines (vertical resolution of 1080 pixels) and a horizontal resolution of (up to) 1920 pixels. All this analog stuff is fading rapidly
