I use the following tools :
- three 3D Viewer for 3D viewing on my notebook and PC (even though I use a 3D TV/Monitor 32'')
- same monitor (shutter) as stand-alone 3D TV with USB-stick
- Sony 3D-TV 42'' Pol-filter
- Commander 3D (Flight Deck) auto-stereoscopic tablet 10.2’’ x 6.7’’ https://www.commander3d.com/specs/
- PPTV King7 S stereoscopic /phablet display size 6'' (very good)
- anaglyph specs (sometimes needed for video editing with Vegas Pro 15 or Magix VideodeLuxe)
- parallel viewing on 2D smartphones
