Which git repo and which branch exactly? You may have a repo without
the patches that fix interlaced modes.

> lxdm resolution set tool).

Which line did you add to xorg.conf? What exactly did you do in this
step? Please try to remove every xorg configuration file and test
again with the default configuration

Please attach the TV, then run "xrandr --verbose" and send us the
output. Please also send the output of intel_reg_dumper:
