Default Re: cannot compute backend DFP timings

You've set the ModeValidation option to reject every type of mode. I'm not sure why you're doing that, but its not a good way to debug the original problem.

However, according to the EDID in your display, you need a 162Mhz pixelclock to run with the native 1600x1200 mode. Your hardware isn't capable of that pixelclock:
