Ok, I'm trying to connect my 13" Macbook Pro to my HDTV. My TV is a 37" 720p Aquos with a native resolution of 1360x768. I want my desktop mirrored. So I bought a Mini-Displayport to HDMI cable. When I connect an HDMI cable to the Mini-Displayport to HDMI cable and then to the TV my Macbook detects the TV, but when I select "1360 x 768, 60 Hz (NTSC Television)" as the desired resolution for the TV from display settings, all I get is a black screen and my TV notifies me that the resolution isn't supported...huh? I downloaded SwitchResX and created my own 1360x768 custom resolution. After a reboot I set my new custom resolution and my desktop appeared on the TV. However, while the top and bottom of the desktop correctly align with the top and bottom of the display area of my TV screen, the left and right sides of the desktop do not. There are black bars on both sides of the desktop image. The problem appears to be that when mirroring, the desktop size resolution can never be greater than the highest resolution possible on the Macbook; 1280x800 in my case. So, while I can select, using SwitchResX, the higher resolution of 1360x768 for the HDTV, and while the TV does indeed recieve a 1360x768 signal, the actual size of the desktop remains 1280x800 and the image displayed on the TV is just 1280x800 proportioned to my display with black bars on the sides. Any advice? This is extremely annoying, I'm about to break down and Boot Camp Windows 7 onto my Macbook. At least in Windows I can perform the ridiculously simple operations of creating custom resolutions that work and resizing desktops.
