Right.. i have my Ps3 running through a hdmi connector box into the dvi port on my tv which is fine. Then i tried to run my laptop through the same box via a dvi vga - hdmi cable but every time i switch it on the screen goes to dpm mode. sometimes when i am lucky i get a grey box appear in the top right hand corner. i have tried numerous leads and all the ports on the box. I have phoned LG and they said the problem is with the box, but it cant be as the PS3 works in every port. any ideas?? Thanks in advance.
