Hi, It was running 2560x1440. I'm not sure if the chip can do 4k although tho= =20 Xorg probe suggests it might. Maybe the rest of the interface electronics= =20 can't support the higher clock rate. r296547 does correctly run the=20 external monitor at 2560x1440. Sadly the monitor is an international flight away from me for the 1.5=20 months so I can't test anything else until I'm back.
