This would be display dependent, also varies between active/passive 3D, but can be used to compare devices connected to the same display.
Excellent, thanks.
On my way back, I got to research on 3D resolution and chanced upon two excellent articles by Dr. Raymond Soneira (DisplayMate) and Dr. Martin Banks & Joohwan Kim (UC. Berkley). Back in 2012, when LG first introduced passive 3D displays, Samsung was debating and advertising how passive 3D only has half-resolution, produces inferior 3D effect and such. LG had complained to the National Advertising Division of BBB about this and the NAD actually ruled in LG's favor. NAD had drawn their conclusion based on these studies and another one from JKP.
Dr. Banks' study used stereoscopic visual acuity charts. Whereas, Dr. Soneira's study used the Blu-ray of IMAX: Space Station 3D. The study checked the sharpness and resolution of small texts that are present throughout the documentary. I think we can use the same methodology to differentiate between FHD3D and TAB/SBS 3D output. Although Dr. Soneira's study found that passive 3D displays produced sharper text, I didn't get that same result on my passive 3D Sony TV. I found the texts to be sharper and more easier to read on my active 3D TVs/projector.
Here are the links to the studies:
1) Joohwan Kim & Martin Banks - Effective spatial resolution of temporally and spatially interlaced stereo 3D televisions
2) Raymond Soneira - 3D TV Display Technology Shoot-out
3) Joe Kane - 3D Display Resolution
I have uploaded a clip from IMAX: Space Station 3D that has several of the texts that Dr. Soneira had used in his study- IMAX: Space Station 3D Test Sample Clip (1.1GB).
The clip is from 00:29:00 to 00:32:00. Here are the location of the texts to look out for in the clip.
I have checked the clip on RPi2, Zidoo X6 and Minix U1 (VidOn 14.2.6 & XBMC for Minix). Surprisingly, VidOn is the only player that cannot play this clip. I am not sure whether this has something to do with VidOn or Minix firmware or the clip itself.
