Mini display port to VGA not showing correctly on TV

I have a new 2012 (June) MacBookPro running 10.7.4 with a 2.5 GHz Intel i5 processor. Graphics Intel HD Graphics 4000 512 MB.

I'm trying to connect a Toshiba flat screen TV to the computer via a mini display port to VGA adapter purchased from Apple with the computer. Sometimes I see 5 lines running down the screen. I can get the screen to show on the TV by changing resolutions and refresh rates (1280 x 768 at 60Hz) but the TV shows 5 partial screens on my laptop screen (between those different vertical lines). I feel like I'm looking at the beginnings of an abstract art piece.

All software is up to date.

Any advice would be appreciated.

MacBook Pro (13-inch, Mid 2012), Mac OS X (10.7.4), mini display port to VGA adapter

The issue persists when attempting to connect to a digital projector for work using the VGA connector. My mid 2009 white MacBook did this like a pro. When connecting the macbook to the TV or projector, I get a black screen with multiple blue/red vertical lines. When am able to show some semblance of my desktop, it is cut up in multiple parts and sometimes repeated between the blue vertical lines.
