The mac was able to output 1920x1080p at 60Hz to the TV. There was noticeable judder when trying to view 24fps content. I searched the net and no one seems to have gotten their mac to output 24p to their Samsung TV.

OK, here is how to get your mac to output 24p to your Samsung series 6 (or higher) TV:

  1. Connect your mac to your tv with a DVI->HDMI cable
  2. Install SwitchResX, which will let you customize display settings on your mac.
  3. Launch SwitchResX and create a custom resolution, using the settings below.
  4. Reboot your mac.
  5. Launch SwitchResX again and confirm that the new 1080p24 setting is available.
  6. Activate it and rejoice!

Here are the setting I used, which might still need a bit of tweeking. I’m still trying to get the vertical refresh to be exactly 23.976Hz. I cribbed from these settings that are known to work for a sony bravia. The judder seems gone, but I still see some occasional choppy playback, I think due to dropped frames during h.264 decode. I’ll investigate further.

I’m mostly happy with my new TV (in true redneck fashion, I traded my pickup truck for it). I originally got a Series 5, but It could only do 1080p60, and I really wanted 1080p24, so I had to upgrade to the Series 6. Unfortunately, the Series 6 arrived with a dead pixel. I don’t know what to do about that..
