I have my macbook hooked up via a HDMI-DVI converter, as all it has is a DVI port and all I have is a Mac-to-HDMI hookup, and the Mac is detecting the TV fine and dandy, but no picture is showing up. The TV is a JVC LT-26WX84. This is a 13" Macbook from late 2010. The Mac-to-HDMI hookup is by Kanax. On my Displays tab on the menu bar, "LT-26WX84" is grayed out. Three other resolutions are listed. None of them work. Thanks!
