Can't detect new Asus monitor

[pazuzu]

I've just bought a new monitor asus VA27EHE. The display went black after clover screen. I'm connecting the monitor through hdmi port. Gpu is radeon HD 5770.

The monitor is working when I plug in my old monitor, Samsung syncmaster to the dvi port and Asus in the hdmi together. The system report shows only one monitor which is the Samsung sync master.

Anyone can help?

Thanks in advance.
