Assuming that the monitor can take that, then yeah, you should get straight 5:1 playback natively. ATi's drivers should know better than to need any pulldown in that situation, but there again, why risk it, I would turn off pulldown detection just in case.

Right. Like he said. If the monitor can actually be set for 120Hz, You should get 5:5 on 24p material and 4:4 on 30i(2:2 60Hz after deinterlacing). Pretty sweet actually. You never have to change your refresh rate.

As best I cant tell from the monitors user manual the 120Hz mode available over dual link DVI is designed for use with the Nvidia 3D application and uses the two links separatly in order to support 3D applications only.
There is nothing the manual that even mentions a 5:5 pull down option when processing 1080P/24 content for it's 120 display. Most likely this is becasue it is designed only as a monitor and not also as TV.
Also I am not aware of any graphics card capable of creating 1080p/120 from 1080p/24 content using 5:5 pulldown.
More Info on the Nvidia 3d graphics solution can be found at:

I know the refresh rate of the monitor's screen is fixed at 120Hz for all content. What I was trying to point out was that after reading the user's guide for the monitor I could find no way for it to receive 24fps content and use 5:5 pulldown to display each frame the same number of times on the TV. In fact I could find no references to any TV signal processing except for the link to the Nvidia Web site for the NVIDIA 3d solution.
And as I stated I know of no graphics card that will output 120Hz over dual link DVI that contains 5 copies of each frame of 24fps content source.
The manual did not contain pictures of all of the screens of the OSD, hoever, I did see one OSD screen that appeard to have a selection for a dual stream input which I assume was releated to receiving dual data streams over the dual link DVI interface.

But I don't know of any video card that will do frame replication and create 120Hz content that can be output over a dual link DVI connection to a monitor designed to accept two different 60 differnt 60fps data streams one over each link of dual link DVI connection to use for 3D projection.
I don't think the radeon card will peform frame interpolation either to create 120Hz content from 24fps source. AFAIK it only knows how to create 60fps content from 24fps source using 3:2 pulldown.

Where do you think Pulldown is disabled since it is not avaialable in either the monit or in the Radeon drivers? Just as frame interpolation is not available in either the monitor or in the radeon drivers.
Remember you bought a PC monitor not a TV so the functions that are available in a TV for the handling of 24fps content are not available in your monitor.
I know of no way you can obtain 5:5 pull down on your monitor from 24fps content since neither the monitor or the graphics card can do it.

It is also impotant to note that the 3D capable monitor can not accept 120 fps content over HDMI and this is because HDMI 1.3 does not have a way on the reciving end to splt two 60fps content streams one for each eye for 3D into streams.
I have found a reference that discuses frame interpolation capabilities on ATI cards being used to create 48fps content being converted to 48fps content see the following link.

I can not find any referencers that discuss 120Hz output from ATI cards other then it use for 3D graphics.

You left out one step
The TV is accepting 1080p/60 film based content.
Then the TV is riunning IVTV(inverse telecine code) which removes the from the 1080p/60 input the 1080p/24fps source content.
Then the TV displays each of the frames of the 24fps content five times by placing and leaving each frame of the 24fps into the 120Hz display's output buffer and leaving it there for 1/24th of a second.

Wally, would you like me to explain how my 120hz TV does 5:5 pulldown, yet it only accepts 1080p60? That one will really throw you through a loop. It buffers unique frames into a frame buffer and displays each one on the screen five times! I know, it's crazy electron voodoo man!(in my best John Stuart voice)
