Hello,
since I have presented the topic of sharpness here in general (i.e. completely detached from sharpness or the impression of sharpness, I am not in the field of photography here) I will not add any further LED wall comparisons here, which prove that it can be even "sharper".
It's about these projectors. I can then later on the subject of Led Wall. Thread write / show something about it.
Let's come to the color representation of the subjects.
P3 DCI and BT 2020 color space (what can these projectors display) ?
However, I will only show certain diagrams in random samples here, since I have no interest in things being questioned here again.
Measured with the Qalif Spektro (Version 3) and a MInolta (that measures the on/off contrast even more precisely).
Therefore, two devices are listed below as representative:
Sony GTZ 380 :

As you can see, the Sony does not manage to match the P3 Dci color space 100%.
In the course of the calibrations, however, something more could be achieved. Blue was already quite good and red got a little better later (green not further).
The other two candidates
Barco Njord CS and also the Panasonic RQ 50 were able to cover this color space with almost 100%.
So here too there are slight advantages for the DLP subjects.
The Barco could even be calibrated exactly to 4 1/10000 steps in white.
Barco itself specifies 5 1/10000 as the default.
It's unbelievable how precisely these DLP devices can be adjusted.
A 3D Lut is in principle unnecessary because there is no white point shift at different. IRE levels can be recorded if you stick to the respective minimum laser values.
But the Barco was also the only one whose white point (nothing danced) could be measured so precisely over and over again.
The RBB laser from Christie "wobbled" a bit around the white point (in the thousands range), which is still better than the "normal" consumer colleagues or colleagues show there.
Here the Christie M4 km 25 :

Base without correction for the Rec 2020 color space.
As you can see, it surpasses this color space in red, blue is also more present in saturation.
Green is on the move, but not quite up to target.
Weiss almost to the point, but he shouldn't stay there..
.
Red + Blue after correction

Red exactly 100% ; blue by 97%

green by 93%
In conclusion, an average of approx. 96% coverage is achieved, which of course no other projector in this comparison can achieve.
If you see how the red alone behaves, then the red of the colleagues unfortunately looks a bit pale in comparison.
But how does it compare now (film, etc.)?
The Christie shows colors, you just have to see it !!!
awesome!!!! This is immediately addictive.
In the first comparison to the Barco, which specified the color balance very precisely here (before all others at this point in time), the Christie then seemed a bit too green in the white.
That was surprising, since it was actually calibrated exactly to the white point.
A similar behavior to the LED technology was shown here (more on that in another thread).
Because the Christie had to be corrected manually here, we therefore carried out a white point shift.
In addition, the Christie has extensive setting options where you can do exactly that.
Here only the white was shifted towards red and green (yes also towards green). After that, the slight green cast was gone.
After that, both devices (Barco + Christie) played head to head with the same brightness (around 190 nits).
And so that we can really see a 1:1 comparison directly, I masked half of the devices in the lens.
The Barco showed the left side, the Christie the right side.
Adjusted in zoom and shift as if we see a projection (only minimal glare visible in the middle).
This "matching" in the form is really the upper hammer in direct comparison.
What's more, we mirrored the Barco image (thanks to the butterfly function in the Barco), so that the same half of the image is displayed (Barco mirrored, Christie normal). So the content is absolutely the same and you can compare exactly.
Then such pictures came out (no evaluation because feasible, since the camera did not recognize the colors exactly, including contrast, etc.)
Therefore the type of comparison is only symbolic.

(unfortunately photos are not suitable to show the contrast range and RGB laser color space here).
And the following things were noticed:
The tuned Christie can display the black darker, including more punch in the picture, if lighter objects are also present in dark scenes. But more on that elsewhere when I explain the Dyna Black again in more detail on the Barco + Pana.
But otherwise both devices looked very similar, in terms of sharpness + movements + normal colors.
But as soon as Rec 2020 colors are added (see Free Guy, for example), the Christie puts the decisive more colors in the limelight.
This is then wonderful to see in a direct 1:1 comparison.
It was also wonderful to see that the more colors could not be seen in every scene. So the Christie doesn't smear all colors mercilessly into possibly too colorful ones. No, he differentiates exactly where it fits and the film also provides the corresponding data.
This 1:1 comparison showed many a detail in films where one would not have thought before that these colors are on the film material.
Therefore, the two DLPs play on an equal footing, with the Barco developing slightly more in-image contrast in bright scenes, as was evident at the beginning when we optimally adjusted the Barco to the Envy.
At the beginning, the color resolution on the Christie via the Envy was not right either, which still looked perfect via the pure MAD VR PC.
That's why I wanted to throw the Envy in the trash....:wink2:
Only the settings were a bit cranked (not suitable), which immediately affected the performance.
You have to deal intensively with the Envy....
Later we set up a Christie + Barco (also Sony + Pana afterwards) "only" and one for both devices, since the devices behave almost identically in the rest of the signal path (sharpening, etc.).
Then we made a crazy comparison!
Look here :

Therefore, not just a projector on the left/right (right side discolored, was/came from the camera).
But on the left with the Envy + Oppo Player and on the right a corresponding solo MAD VR PC with films from the festival (Kodi).
And then played it synchronously 
(only after about 35 minutes was it no longer frame accurate).
Nobody has done that before.
The findings from this are also very instructive, but unfortunately I will not be able to give any information here.
How the other two candidates then performed in comparison follows in the next part....
