I'm trying to connect my mid 2009 Macbook Pro (5,5) to a Vizio sv370xvt 1080 TV as an extra monitor. I'm connecting it via mini-display port to vga adapter. The adapter is the official apple brand, not a generic brand. It's connecting fine, but it's only displaying on the TV at 640x480. No matter what settings I use it will not let me change the resolution. It lists 640x480 as the only compatible resolution for the TV. It works fine in OS X. OS X gives every possible resolution up to 1920x1080 as compatible resolutions. Anyone else experiencing similar issues? Anyone know how to resolve it? Thanks.
