I recently purchased a Mac Mini to be my home media computer. I plan to blog more about that later. For now, the only tricky thing about using a Mini has been using my TV for a monitor.
There’s a lot of noise on the web (or Google at least) when trying to search for a solution to using a Mini’s DVI output on LCD TV’s. Typically they recommend using DisplayConfigX or SwitchResX to tweak your display modelines, timing, resolution, and just generally dive deeper than I like into display configuration. My solution was MUCH simpler.
My television is a Samsung 46″ LCD (LN46A539P1F). It has 3 HDMI inputs, but one is specifically intended to be used for PCI DVI input converted to HDMI. It also provides a VGA DSUB input which works perfectly with a Mac Mini’s miniDVI->VGA apapter, but the point here is to get direct digital signal without converting to analog.
The Mac Mini has a miniDVI output and is packaged with a miniDVI->DVI adapter, so to get a signal into the TV, you’ll need a DVI->HDMI or miniDVI->HDMI adapter. I bought both from Monoprice as they are very inexpensive and either works fine.
Once you have the apdapter on and the HDMI cable connected to the TV, the Mac will recognize that it is displaying on an HDTV and will recommend 720p (1280×720 resoution) or 1080p (1920×1080 resolution). However, you will now most likely see that your output is either too small on the screen (has a few inches of black border around the picture) or is too big (extends beyond the screen). If it’s too big, you have Overscan enabled in your Displays preference pane. If not, you should enable Overscan.
Now, on your TV, go to the Menu:
- Choose “Picture” (should be first option)
- Choose “Picture Options” (near the bottom of list)
- Choose “Size” (will have options like 4:3, 16:9, and Just Scan)
- Choose “Just Scan”
- Close Menu
Bam! Your display should now be just right!
