MBP external monitor

[troyman11]

Hello, my LCD is broken on my MBP and I was trying to use a 32inch tv as the external monitor. It says no signal on the tv. I think the resolution is set so its unable to display on the tv. I have tryed connected the mac to an old crt monitor and it works fine. Is there a way I can change the resolution of the tv through the computer or set a default so all external displays are a certain resolution and change it from there. VGA connection. old silver MBP

Not sure, but DVI or hdmi should not have this issue.

have you tried booting up the computer while it is connected to the TV?
