Connect MBP to Polaroid TV via HDMI 'not supported'
I have a MacBook Pro model 5,4 (mid 2009 15-in). I'm trying to decide whether to get a larger external monitor or a TV. I want it for editing photos in Adobe PhotoShop Elements. Before I buy anything, I've decided to experiment with the Polaroid (brand) 19" TV in my bedroom. The TV has an HDMI port; I have a mini-DVI to HDMI adapter and an HDMI cable, so I'm ready to go ... right? Well, I put it all together and changed the input on the TV to the HDMI port. Result: "Not Support!" [sic]
At this point, I have no idea where the problem lies. Is there a setting I can change in my MBP? Did I buy the wrong mini-DVI to HDMI adapter? Or is it the TV itself? How do I figure it out?
My mini-DVI to HDMI adapter is an "Accell UltraAV Mini DisplayPort 1.1 to HDMI Passive Adapter."
