Depends on the display, "small" is obviously a relative term.

and (as u might know) then there's peeps saying they're doing a manual disc cal and it matches a 6pt cal done by a Pro using high end meters.

but, naturally a "bad" 3D LUT can be outperformed by a good 6pt cal, even THX as is... ;-)

1D LUTs are supported in semi-pro / lower-end pro screens and is Greyscale only, helpful if the gamut is spot on or can be controlled.

Thanks for the clarification, I understand that luts can be more valuable depending on the set. At least you concede it is a "small" difference. Appreciate you acknowledging that !

why don't u run a 101pt or 255pt Greyscale and then post images... ?

ah right, that bubble you live in... u know, sometimes it's better not to know the truth...

your bff Zoyd with your other AVS only bud Gill is giving you the gift of free 65^3 cals but u just can't escape that bubble...

btw, IQ can't be measured... ?!? let me... wow... okay... well.... Larry, good luck.

Wow, you do seem to think that you know all. I've been using Argyll (not ArgyII) for many years. You don't know that but apparently you have no problem assuming it.

With one of my spare laptops, I ran a 729 point cal on my old Panasonic X1 using the command line Argyll and MadVR. The results were great and readily apparent. However, doing the same to with my VT60 yielded no visible difference at all compared to a standard HCFR calibration -- no visible difference at all. In other words, a 3DLUT has its place. That place is not with the VT60 however.

That is my only real point, it is not to dismiss 3dluts at all. Just IMO the effort and cost produces very little visual benefit. Even Buzz has mentioned you would have to compare side by side with the screen paused to see the difference.

Yes. The Lumagens process all 3D formats and the eeColor Processor is limited to side by side or top/bottom (not sure about checkerboard). The eeColor will not process Blu-Ray frame packed 3D but this can be circumvented by ripping a Blu-Ray to an MKV file.

As Mike said, cycling a 3D LUT on and off on paused video will show a difference on any display. In my observation, color tracking on the VT60 is good enough that the difference will not be seen on motion video as opposed to displays that do not track well like the Sharp Elite.
