Shutter should blocks all the lite from projector. When it opens there are two stages; first is the blank rectangular screen 1920x1080 with low intensity but it degrade polymer and the second - projecting the real slice image.
Is it possible to remove/make shorter a delay between opening shutter and projecting next slice image?
Look at the video, please

This delay about 3 seconds.

You have both RPi servo and shutter gcode enabled. If you have wired your shutter to RAMPS change shutter type. If it is connected to RPi remove shutter gcodes.

Yes, you are right.
Shutter connected to the RAMPS
Should I desable Shutter in the Setup page ?
Offline
Yes disable it as nanodlp is not in control of the shutter.

I understand that in the current resin profile there is 2 sec delay for resin releveling/bubbles out. Is it possible to make shutter opening 0.5 seconds before real slice projecting?
Could Pixel dimming also decrease parasite effect?

You need to modify gcodes, I am not familiar with muve3d gcodes.

Could you check these settings? https://cl.ly/151E0o0p2m2a
I failed my last print with them. I changed "Wait Before Print" from 2 sec to 0.3. It solved an issue with 2 sec blank projection image. But I need 2 sec pause after lift to let polimer surface distribute. What is correct place in nanoDLP Profile page to put this 2 sec delay?
I have set Wait After Lift 1 sec but actually there were no any delay. Movement down, shutter opens, 0.3 sec delay, projection the slice image, shutter close, lift up.
I`d like to get
Movement down, 2 sec delay, shutter opens, 0.3 sec delay, projection the slice image, shutter close, lift up.
