I have a laptop with an ATI Mobility Radeon HD 5470 and would like to use a second monitor, which is actually a TV, via HDMI.
The problem is that the system does not recognize the second monitor. I can not even switch the display between the laptop monitor and TV.
The problem is not with the hardware because I can do this in Windows 7.
To say the truth I managed to send the screen image up to projectors. Only in this case I have problems.
