Hi

I would like to send out 1080p 24Hz from my iMac.

I can only choose 1080i 50Hz and 60Hz.

I installed DisplayConfigX but as soon as I install a custom resolution with that program, I only have the first created resolution available.

Meaning, I add 1080p 24Hz, 1080p 50Hz and 1080p 60Hz but only the 24Hz one is available after restarting.

Also, what settings should I use for 24Hz output. Front Porch, Back Porch etc?

Maybe someone here has had success with outputting 1080p 24Hz from the Mac?

Hope someone can help :)
