I have a Macbook purchased new in December of 2009 - I believe the most current model. In an attempt to watch Netflix on my TV - Vizio 32" VA320E 720p, per the recommendation of a Best Buy employee, I purchased a mini DVI to DVI adaptor and a DVI to VGA cable. This setup seemed pretty straight forward, but after several failed attempts and reading help posts online in forums (this forum included) and even more failed attempts, I have run out of patience. The input settings that I am supposed to use with this setup are listed as RGB in the TV's manual and when I follow all of the proper protocol/procedures: turn both the TV and macbook off. Hook all of the cables up, including the 1/8" audio cable. Turn TV on first then the computer. My computer detects my TV but the TV does not recognize ANY signal in ANY input mode from my computer. In RGB mode, it says there is no input source and the TV turns itself off. The TV displays are 1368x720 and my computer operates on 1360x720. Could this be a source of my problem? A side note - I attempted to connect my macbook to a projector system via this same setup in a classroom at the university that I attend and the projector setup never recognized my computer either. However, a Macbook pro nearby connected with no issues, and no manual changing of display settings. Should I ditch this this cable setup and do DVI to HDMI? S-Video? I need help!
