I just bought few days before an LCD monitor acer G206HQL , i tried the first time to connect it into Sony Vaio notebook with vga cable (both of them). The monitor monitor wrrote "no signal" , i tried to fix the problem go to preferences, changing the resolution of the second screen, set the mode for external monitor, but nothing.
The second time i tried to connect the notebook with HDMI and monitor with vga, but again nothing, the monitor wrote cable not connected. I went to the graphic card settings and it spotted the monitor, but it doesn't recognise it. It writes "uknown". Please can you help me fix this problem?
