1080 23.98 AJA Kona 3 to Sharp Aquos

Thanks in advance for anyone that can figure out the weak link in my chain. Of course, the issue at hand is trying to view a 23.98 sequence with a 23.98 reference on my LCD monitor. It will display an NTSC just fine. I can also get 23.98 sequences to play if the reference and payback output are set to 1080i29.97

FCP 7.0.2
AJA Kona3: 1080psf 23.98 Apple ProRes 422 sequence
AJA Kona3 with breakout box Version 7.1
AJA GEN10 Sync gen. set to 1080psf 23.98. shows up as 1080sf24 in control panel
AJA SDI to HDMI converter
HDMI into Sharp Aquos LCD

Payback output set to AJA Kona3: 1080psf 23.98 Apple ProRes 422

That tv must not accept 24p or, there's sometimes a menu a consumer tvs to enable progressive material, which usually means 24p in the consumer lingo.

You have 3 choices-
the converter does not support 23.98 (ha5)-( use either the hdp2 and ha5 3G)
Or the monitor does not support 23.98 wont. Uncommon with consumer displays- I see no mention of 24p on the aquous site.

Or both- neither your converted nor your display support that frame rate in 1080. (not 720p24)

Thanks Jeremy and Gary.

The converter does accept 1080p23.98 and 1080p24 signals and the tv has a film mode which "automatically detects a film-based source ( originally encoded at 24 frames/sec ) analyzes it then recreates each still frame for HD picture quality"

Like I said, I am getting to work using the 1080i 29.97 playback. I just feel like that's cheating.

It's not. It used to be the only option for a while with CRTs.

Just because your consumer monitor say it supports "film" does not mean it supports 24p as a signal.

Did you try component to test? Then there is no converter in the mix- if the tv accepts 24p over analog- it is thie converter- if it does not your problem is the tv.

And you did not mention which converter you are using there, please tell us the model number.
