ThinkPad T61 on a LG Scarlet at FullHD

The question in pretty simple, my girlfriend just bought a LG Scarlet and obviously I had to configure my notebook to work with it because... Because... Well because I like these shits :D. The way is really straight forward, you just have to do the right configurations on your /etc/X11/xorg.conf and use the right mode on your xrandr parameters. Follow this simple tutorial and you will have your Linux working with a FullHD TV with 1920x1080 :)

Change the Screen section of your xorg.conf to be like this:
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Subsection "Display"
Virtual 1920 1080
Endsubsection
EndSection

Restart you X. This new configuration will allow you to add new modes with xrandr:
xrandr --newmode "1920x1080_24.00" 74.25 1920 2558 2602 2750 1080 1084 1089 1125 -HSync +Vsync

xrandr --newmode "1920x1080_50.00" 148.50 1920 2448 2492 2640 1080 1084 1089 1125 -HSync +Vsync

xrandr --newmode "1920x1080_60.00" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 -HSync +Vsync

xrandr --addmode VGA 1920x1080_24.00
xrandr --addmode VGA 1920x1080_50.00
xrandr --addmode VGA 1920x1080_60.00

This are the three common frequencies (24Hz, 50Hz and 60Hz) choose the one that fits better on your TV like this:

xrandr --output VGA --mode "1920x1080_60.00"

Note: LG Scarlet works only with 60Hz.
