The passive-3D monitor at 60Hz is like comparing apples to oranges with a 240Hz active-3D shutter projector. LG has passive panels with better specs, including both 120Hz and 240Hz. Do you recall which Vizio model you're using?
What I'm claiming is that with a 240 Hz monitor, the jerkiness is pretty much hidden. Same disk played on a 60 Hz monitor is obvious to the viewer. Worse is the fact that 24p native is also
obviously visible on the 60 Hz monitor.
No argument in the theory that 30p has more frames per second than 24p. I do believe that with a 240 hz display, the difference is difficult to detect. And, the difference between a conversion and a native is very difficult to detect in both 240 Hz and 60 Hz. displays. Bottom line- there is a magic to 240 Hz displays when having to deal with 24p or 30p or 60i as it all looks good.
It is unfair to offer what may be available in displays in the future as a solution; when I bought this Vizio there was no LG 240Hz 32" 3D LCD panels being offered. I don't know that there are even today but maybe next year. A quick search shows that LG today has 240 Hz 47" panels but even their 32" models still are only 60 Hz.
Unfortunately, I have certain restrictions limiting my choices in selecting a monitor- In order of importance:
1. The obvious one is I can't buy what doesn't exist.
2. Must be 3D passive technology for the edit workstation. I can't work long hours wearing active shutter glasses due to eye fatigue.
3. Can't be bigger than 32" since bigger won't fit in my work space.
I did not list cost because I had a budget to spend 4 times what I paid for the Vizio so if I could have purchased a 240 Hz monitor last June in 32" passive 3D I would have.
Next year, if I can get a 240 Hz monitor to replace this Vizio, I will likely do that. The difference for either 24fps native or converted 60i to 24p is dramatic enough to justify the change.
On the 17th, weather permitting, I plan to shoot another fireworks performance using my twin TD10 rig in 1080 24p native. I think fireworks is the most challenging 3D subject to shoot in 3D. I know now that 24p will display on 240 Hz monitor fine. Not so fine on the 60 Hz monitor. But then neither does 60i. But once I leave the edit phase, I don't care how it looks on the 60 Hz monitor.
