Fitting the picture to a TV screen.

I'm just trying out my new B+ with an old HD Ready TV (720p I think) and
having problems fitting the picture to the available space.
If I turn overscan off then the picture edges disappear - and the task bar
is just below the screen.
If I turn overscan on then I can get the width O.K. with very small values
of overscan_left and overscan_right but I have a large gap top and bottom.
Is there any easy way to stretch the picture vertically?
[overscan_top and overscan_bottom are currently unset.]
Cheers

with my 1080p Samsung a perfect picture was obtained by setting overscan off on the pi & the TV to picture size to fit.

I would have to set mine up to find out how I did this, but, have you tried setting them yet? Try +5 to start, then go larger, and if they go the wrong way, try a minus figure.

AFAICR it's adjusted in one [of the few] text-files in /boot. The "# " makes it clear.
grep /boot/* might take you there.

It is adjusted in /boot/config.txt - which is where I've been working with the 'overscan' settings.

Well done that person!
For some reason I had never considered that you could use a negative figure for overscan.
Much editing and rebooting later I seem to have a fit to the screen.
Wouldn't it be nice if you could re-read config.txt and apply the changes without rebooting!

The tvservice command can switch video output and modes. The fbset command will change the framebuffer to match, and the code here:

can check and change the overscan settings on the fly.

Thanks - will give that a look.
