[mythtv-users] Need help with xorg.conf for DLP projector HD70

[Gregg]

I have been banging my head against the wall trying to figure out why the
screen will not display in full size.  I have a 16:9 screen and the picture
is centered.The resolution says it is set to 1280x720 I have added modlines
and metamodes, but I admit I am a bit confused.   I run the projector from
my cable box directly it fills the whole screen.

any help would be great I have been googling all day for the answers. below
is a copy of my xorg.conf if that helps. (sorry it is a bit messy)

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#Option"Xleds""1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
#Option"XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#Option"XkbModel""pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#Option"XkbModel""microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#Option"XkbLayout""de"
# or:
#Option"XkbLayout""de"
#Option"XkbVariant""nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#Option"XkbOptions""ctrl:swapcaps"
# Or if you just want both to be control, use:
#Option"XkbOptions""ctrl:nocaps"
