Yes sorry that should have been

Code:
xxd /sys/class/hdmi/hdmi/attr/edid
cat /sys/class/graphics/fb0/modes

Code:
root@raspberrypioldpi:~# tvservice -s
state 0x120006 [DVI DMT (57) RGB full 16:10], 1680x1050 @ 60.00Hz, progressive

So why is your RPi not use 1080p @60.00Hz? This is the only physical resolution currently supported with my images.

Written 256 bytes to edid.dat
root@raspberrypioldpi:~# edidparser edid.dat > edid.txt

So, from the edid data your monitor does not support 1080p @ 60Hz and thus does not work.

See http://paste.ubuntu.com/15954272/ as example for a TV which works without any issue (Toshiba).
