1. Make sure you have selected the correct inout on the TV
2. Make sure laptop has selected the external monitor (using Fn and an F key)
3. Cables are plugged in tight
Thank you for your reply.
I tried doing that, but still not working. I borrowed my flatmates laptop, but hers is working on my LCD. So I guess, the problem is my laptop.
Do you have any idea how to fix it?
Thank you, again for the help.
