Just completed the SDR expert Dark room, night settings .
What I have done is attempted manual 2 point, then use 1D lut 10 point grayscale, finally use another 1D lut 21 points for fine tuning the grayscale. All using auto cal to input the numbers in 2 point, 10 point and 21 point grayscale
With 10 point grayscale only , the first attempt
Below 10% grayscale, a bit of difficulty as you can see from the graph above, this was using BT1886 initially. Eventually a few rounds of looking, decided to go for gamma power of 2.4, and they looked assolutely stunning post calibration
Yes, not gamma 2.3! Because there is no option for gamma 2.3 on the LG. So instead went with 2.4, and the results were really satisfying
Was watching penguins of Madagascar, the blacks on the penguin fur, deep and inky like blacks, with iris set to 5, adaptive contrast set to high, dynamic contrast set to Low. Gosh! The pictures really pop, with no eye fatigue.
It feels as if I’m moving from 12bit colours to 16bit colours. It’s not over saturated, but very rich in colour. The reds are like Ferrari type of reds, like when u look at cars, some of the red paint with cars, looks dull. This one looks really rich, the first time I’m seeing the red logo on YouTube looking so rich and has so much depth
Whichever guy online doing review and who says this pj cannot give u deep blacks, probably hasn’t done his homework in bringing out the best from the PJ. The answer is yes, it can give u good blacks without losing shadow details . The meter reading won’t lie, you can see it with your own eyes post calibration
Now that I’ve completed both SDR for both oppo 205 and Xbox series X’s inputs, it’s time to move on to HDR, biggest challenge now !!
Out of the box settings for HDR already looked stunning . I took a quick picture of this scene from spears and munsil,
We can see the bright sun 
at the right hand corner of this pic. If the tone mapping is good, we can see the sun round and nice, clearly. Otherwise, it will disappear and be part of the sky, and will look like faded, sort of like faded together with the sky. that’s a sign of poor tone mapping
The above is another version I got online 
, someone else’s pic, so much loss of shadow detail to bring the sun out! 
Oh yes, and it had problems showing the details in snow in the background on that horse scene when switching to 4000 nits content. So I’ll need to work on that see what it can do
I will share the same pic post HDR calibration, later so we can compare before and after .
The RGB is really different with the laser light source, very nice indeed. Best part, 20,000 hours !!
Given the controls and versatility from this pj, it’s gonna be really difficult to switch to another projector when u lose that controls. It’s just a different ball game, especially for calibrators. And yes, the controls are all working as intended. Adjustments made to each control will show u what it is doing to the picture. (Important to also establish, because some settings could be there, but it does nothing or nothing working as intended )
