Hi,
when I connect my dell m1330 laptop to my LCD acouostic solutions tv via HDMI to HDMI the LCD screen stays blue and then starts flickering with multi coloured vertical lines (only top half)and this is displayed: m442xm442 75HZ
and my laptop screen goes blank and even if i take the cable out i will then have to restart my laptop to get it working again.
I have always used my LCD in the past as an external monitor and I do not know why I suddenly have this problem.
All my drivers are working and up to date. I have tried changing HDMI cables in case the previous got damaged.I have used Fn to try changing the screen displays...I dont know what else to do?!
