First- forgive me about some possible english mistakes.
So I have an Imac 24" and i finally decided to connect it into an external monitor- a LG 24" screen. I bought a perfectly new Mini displayport to HDMI adaptor and an HDMI cable and I tried to connect it.
unfortunately, the TV is keep showing a "no signal" massage.
I tried to look the display preferences and I found out the IMAC recognize the LG screen and it even gives me to change the resolution and the colors, but it doesent matter because Its keep showing a no signal massage.
I tried to reconnect all the cables and the adaptor and restart the computer and change the tv resolution and it still doesnt work.
any idea- someone?
