Expected resutl: the whole framebuffer fits on TV1.
Actual resutl: Image is zoomed vertically, and, low part of framebuffer is cut. Horizontally ok.

Workaround:

$ xrandr --verbose --fb 1067x600 --output TV1 --set mode PAL --mode 800x600 --rate 50.00 --scale-from 1067x720 --output LVDS1 --mode 640x480 --pos 0x0 --panning 1067x600+0+0/1067x600+0+0
