went to watch a lovefilm movie today ,but no picture on the tv when the hdmi cable is plugged into the laptop
Yo, set your tv to automatically switch to connected devices
mine does this on toshiba, that should sort it out, i had same prob doing my skull in when i wanted to play games off my laptop.
EDIT*
yo, just realised if your tv is not full hd it wont work unless you turn the hd settings down on your laptop, its a safety device on older tv's that are just hd compatible so the laptop doesn't damage the tv.
put the model no. of your tv up and we will be able to let you know this.
