Meant to be Seen

Just wondering if anyone is making 144Hz monitors? For film viewing, 24fps doesn't really fit into 60HZ per eye without 3:2 pulldown and the associated annoying judder.

96Hz or 144Hz are really the only options for smooth framerates for movies, does anyone make 3D TVs or monitors that will do 144Hz?

120Hz is the first standard set it seems. It'll likely take some time before it changes due to the bandwidth needed for higher resolutions. Solutions which uses side-by-side, interleaved etc for transmittance could very well without problem increase the refreshrate if they desire.

Computer displays do not generally sync to the interlaced 60 Hz video source (unless they also have a HDMI input, which is rare). Computer monitor have been traditionaly been using progressive refresh with multiple frequences such as 60, 70, 72, 75, 85, 100, or 120 Hz; I'm currently using an old 19" CRT monitor set at 1360x960 @85 Hz, and I'm playing back 50i, 24p and 60p video content, all without any hiccup.

Computer video player software just outputs the video to the overlay as needed, and no-one performs any frame rate conversion or employs any pull-down techniques (unless these are hard-coded in the video). The frame rate of the video content and the refresh rate of the monitor are not interlocked in any way; the "conversion" happens naturally, and no-one has ever complained about framerate judder or similar problems. Interlaced video can look nasty though, just as on any progressive display including all current HDTVs.

Actually, movie purists do complain about 60Hz not being a multiple of 24fps and the small jitter that occurs on LCD or Plasma displays.
Is it an extremely small effect but hardcore cinema enthusiasts do see it. This is why manufacturers now include 24p modes in the displays specifically for movies.

For instance my Epson projectors do support 24p input, I read on user forums that the 24p mode was actually running the projector at 48Hz display rate.

i don't understand why you need 144hz, aren't 120hz also a multiple of 24 ?

I also see it on camera pans (that's the easiest way to spot it) on my 85Hz CRT. So when I watch 23,976/24 fps video, I watch it on custom mode with 96Hz, and using ReClock filter (which does 23,976->24Hz audio resample on the fly) I get the perfect synch. The same thing goes for smooth pans in 60fps videos and 85Hz refreshrate, but I can do almost nothing to correct it, as using 120Hz is not very good solution most of the times (more blurry picture on the CRT which, in 2D, is distracting), but it appears in rare cases anyway.

It is, but its not... ideal . In 120Hz 3D mode you get L1-R1-L1-R1-L1_R2-L2-R2-L2-R2_L3-R3....
With 144Hz you'll get L1-R1-L1-R1-L1-R1_L2-R2....
