We are trying to establish an Avid DNxHD offline system. Mojo DX's output is 24Psf. no customer TV that i know of supports this format. how can I monitor the transcoded R3D to DNxHD 36 for offline on a cost-effective monitor?
Is there any Mojo that can output 24p instead of 24Psf? any hardware box that can do the conversion?

thanks.

If I'm not mistaken, the Sony XBR6,7,8 line supports "true 24fps," as they claim. Go to their website and check.

I use the HP Dreamcolor over HDMI... when I use consumer type monitors, I switch the output to convert to 1080i with pulldown which works for us in NTSC land..

Sony CRTs do support true 24sF, but you're right, it comes with a caveat. When it displays PsF, it can only be achieved via a 1080i source. The XBR series has a 3:2 pulldown removal card in it, allowing for progressive display from the 1080i signal, but it is not able to decode a 23.98 signal.
Some XBR series monitors (it varies) are able to display 23.98sF over DVI/HDMI, but not over component. But depending on the options, the decode from 23.98 HDMI might have additional problems, like not being centered or sometimes it is improperly aspected.
If you are looking for other consumer monitors that do support 23.98s, Panasonic's series of Plasma screens are amazing. Series 9, 10 and 11 have very high end engineering menus, allowing for surprisingly accurate calibration control. Plus, almost every LCD that has a DVI or HDMI output will support this signal.
Can you not set your Mojo from a 23.98 timeline to add 3:2 making a 1080i signal?

Being in PAL land I don't think they want to go the 1080i with pulldown...

Thank you all.
I found a consumer TV that supports 24psf, at least in the specifications. I will further investigate it before importing to Israel.
If it works I will update.

The Sony XBR series will do 24p over hdmi which means that you need a converter to get to hdmi. Both Blackmagic and AJA make mini-converts to get HD SDI to HDMI but here are the limits on each converter:

Blackmagic SDI to HDMI converter:

24p - no picture
23.98p -no picture
23.98psf - good picture

AJA Hi-5 SDI to HDMI converter:

24p -good picture
23.98p - good picture
23.98psf -no picture


That was the results that I got using the two different converts connected to a Sony XBR and feeding it with a signal generator.

You don't need a converter. The Mojo DX has an HDMI output.

Correct and supports 10bit and settings allow for YCRB or RGB settings on output.
