    Hey guys, ive been floating around on here lately and I need some help.

    I have a macbook pro and i used my old phillips tv for a 2nd screen. Bought a DVI-I to DVI-I cable, and was working just fine. For xmas I got a Dynex 26inch. I noticed it has a VGA and not DVI input, so I figured I would buy a DVI-I to VGA adapter and still be able to use the same cable. I go to hook it up and my TV says no signal.

    On my laptop it detected the tv as BBY LCD TV, but still has no picture. Is there a setting I need to change? Or is the better route going with a new DVI-I to VGA or HDMI cable?

    Thanks guys!

    Could be a defective cable/adaptor.

    Personally, I use a little Mini Display to HDMI adaptor off of Amazon for a few bucks and that does the job really well.

    Would you recommend buying a dvi-i to hdmi adapter? Or a whole new DVI-I to HDMI cable?

    There's a difference between DVI-I and DVI-D and sometimes the VGA adapters don't work with, well, one of them.

    Well i tried my room mates DVI-D to HDMI and it worked perfectly. So i guess the DVI-I to VGA just doesn't work right?

    vga is not digital. dvi is. the cable wont work bc its not converting the signal. i would use a dvi to hdmi adaptor. then you will get digital quality.
