Having a hard time getting the timings you want working?  Try this.

config.txt:




Then execute this command (or put it in rc.local)
vcgencmd hdmi_timings 2880 0 55 10 55 1600 0 30 6 570 0 0 0 90 0 593000000 3 && tvservice -e "DMT 87" && tvservice -s

Did you just check out / clone a repository and forget --recursive / --recurse-submodules? Well, do this:

git submodule update --init --recursive --remote

//I am still experimenting with both options to see which is better overall and
