weird that it still read from the EDID, even though you have the
option not to, I guess this is related to the CustomEDID forcing it
way.

So you have 4 1440x900 modes

Remove the :
"UseEDIDFreqs" "False"
line

Restart X and try to go through all the 1440x900 modelines
DISPLAY=:0.0 xrandr --output default --mode "1440x900" -r x (where x
is 50 to 53 inclusive, 52 with UseEDIDFreqs set to true)

If that still doesn't work...

You should post on the nvidia linux forum:

There are many TVs not accepting their native resolution when using
hdmi and they only take official one like 1280x720 or 1920x1080. Your
TV accepts those, try with them (
DISPLAY=:0.0 xrandr --output default --mode "1280x720"
)
