MBP won't detect Sharp Aquos TV (DVI->HDMI)

[derrylwc]

I normally use an additional Samsung monitor with my MBP (DVI -> DVI) with no problems. The computer always detects the external monitor and designates it as the 2nd screen.

However, I tried hooking my MBP up to my Sharp Aquos television with a DVI-HDMI cable. When I have it plugged in, and navigate to the correct input on my TV, nothing shows up on the TV. The screen on my laptop temporarily blanks out and resets - as it does whenever I connect my Samsung monitor - except when it resets, nothing has changed, and nothing displays on the TV.

I tried to "Detect displays" and tweak anything else that I could under Preferences > Displays, but I'm at my wits end...

Does anybody know why it might not be showing up?? Thanks!

I have a sharp tv as well and sometimes I do not get picture on the tv even though it seems to be working on my mac. I found out that if you reset the tv to factory settings it seems to fix the problem. See if this works for you too
