THanks a ton in advance

Thanks for the logs. The driver seems to have problem in reading the EDID of your display, so it tries to use default modes (but unfortunately these modes are not good for your display). What kind of display are you using? Just for testing, does it have additional inputs other than the display port one?
Thanks
