HD4670 Detects HDMI TV, but no signal - Mavericks

[bmas]

Hi all,
I`ve got a problem and still no solution.. hope that somebody will help me.

My hackintosh is with AMD HD4670 and everything is perfect but HDMI signal.



I connect my TV trought HDMI, Mavericks detect everything fine, but I dont have signal to TV, just blank screen.... What could be the reason?

Finally I`ve got some partial result:
1. If I unplug monitor on boot with just HDMI plugged, the TV and HDMI work.
1.2 After that, I plug and the monitor so both work together.
1.3 After wake from sleep, HDMI TV does not have signal again.

How can I fix that or everybody have same issues ..
