I was reading that most digital computer displays are only 6-bit output to allow those really low response rates and you have to specifically look for a true 8-bit native digital display. I hadn't really thought about it before but with all the push for faster panels for 3D, now I wonder:


Are the Panny, Epson, Sony, JVC, etc. digital projector panels 8-bit native or are they 6-bit with dithering to fake 8-bits?


It is something that is not stated one way or the other so I don't know if they are obviously all 8-bit or they just don't want to state they are only 6-bit and hope people just assume 8-bit. No reviewer ever mentions it either so this may be a non-issue.

But is that true 12-bit panel output as in it can actually display 4096 shades of gray if it was given a 12-bit input signal? Most of the literature on projectors from companies gets very vague and talks about "12-bit processing" or "12-bit drivers" or "12-bit input" but it never clearly states X-bit actual panel output. There are plenty of 6-bit output panels that say they can handle 12-bits. This is similar to the earlier days of HD projectors claiming to be full HD but what they meant was they could handle a 1080p signal, not that their panels were actually 1920x1080 and it took some effort to find the projector's native resolution.

The Planar 8150 had 12 bit panel drivers but depending on how you had info flowing in (colorspace, resolution, what features you were using on the PJ) you may not be taking full advantage of it. I don't remember all the details as it's been awhile but I believe I mentioned it in the review. I had a long talk about this with their lead engineer on this during the review process. I always try to find out what the best input signal is for keeping the panel drivers operating at their optimum, which usually entails what colorspace you feed and what features you have on or off on the projector (like sharpness, NR and other display enhancements).
