HK/China is starting to make action films in 3D, so I'm considering getting some sort of 3D display/projector. Are the low-end systems (PS 3D Display, Epson 3010, Optoma HD33) up to very fast action (much faster than Hollywood)? Does one need a higher-end system, or does no home system do a good job with 3D action at this point?
You don't need a high end system for great 3d. I would choose a dlp 3d projector or tv ,which don't have problems with motion ,ghosting or crosstalk like lcd. I have an active 3d setup, an Optoma hd66 projector and the 3d is great, never no problems with motion or anything else.
I didn't want to spend a lot to add 3D in my theater so I purchased an Acer H5360 DLP projector and it throws a great image with my PS3 and games. No motion issues. DLP is the best for motion and 3D IMHO.
I have the Optoma GT750 entry level 720p DLP projector. It is really fantastic with gaming (720p60) and bluray 3d. However when fed 1080p24 for 3D bluray I will say that some fast action scenes can sometimes show some blur/judder type effects. I think a 1080p unit with CFI (creative frame interpolation) might help smooth out so of these minor motion effects.
