I received my LUNE 4K yesterday and tested a lot (thanks for the comments inside the thread, it helped a lot)
The control menu of the LUNE 4K is very confusing and complex, but you can find the most important picture settings and it is also possible to play HDR via external players, without any quality restrictions.
I try to give an overview about the fundamental settings and issues I faced if the wrong settings were choosen.
I have no picture wall yet so the images are based on LUNE 4K which was projecting on an uneven, yellowish wall
Zidoo Z9X HDMI OUT --> Denon X1500H --> LUNE 4K HDMI 2 IN/ARC
(as an example of other devices):
Firmware Version 2.1.40 is used
Display Resolution is 3840x2160P @ 24Hz
YCbCr 444 @ 10bit and 0-255 range
SDR to HDR mapping causes picture artifacts thatswhy Ineeded to use AUTO settings on Zidoo side
Zidoo HDR Auto Mode
Due to the setup it was needed to adjust the audio delay slightly
The delay was between 25ms and 50ms... I used 25ms setting to solve it.
LUNE 4K basic settings:
In the LUNE 4k there are four different setting menus for the color settings.
The basic settings can be adjusted inside the "quick-menu".
Therefore you should select your favourite input port of the LUNE (in my case the hdmi2).
The connected source need to be active, otherwise you are not able to open the LUNE setting.
Press SHORT time
the setting button of your remote
The following menu should appear on the left side
Enter the third collumn first and make shure it is set to HDMI 2.0
Now you need to go one step back and enter the first menu and change your settings if you like to.
I prefered to deactivate all enhancers. I kept the standard color, due my screen not arrived yet.
With this basic settings I am able to get Full HDR and the picture looks pretty and colorful.
If you like to adjust the colors of the LUNE 4K more precise, you need to use the hidden menus of the device.
Please do pictures of the default settings before you touch them! If you change the following settings, they maybe not reset within factory reset!!! All changes are made at your own risk!
LUNE 4K advanced color settings:
Go to settings and select the "about" menu
After you entered the menu you should see
Now you should press and hold the left button
on your remote
The factory setting menu should appear (black backround color)
It seems to be the basic menu for the major adjustment of the device because test patterns are included and the voltage power of the RGB sentivity can be fine adjusted.
If you like to have a look for it...
Go to the following item and enter it:
Under calibration data menu you will find the default settings of your device. You can do a picture of it if you need a fall back later on.
You are also able to fine tune the parameters but I would not do it inside this menu, therefore we have other possibilities.
Go back to the "about" menu
Press and hold the right button
of your remote
The Design menu should appear
Select the first collumn Factory menu
Under ADC Adjust you are able to finetune your RGB (like for calman ect.)
You can do it for SD and
Under W/B Adjust you are able to select the RGB parameters more individuel for the different color modes
Now you are able to set your own RGB values and gamma correction.
It i is my first post so please do not hestitade if I you have comments.
