I won't list any of the video artifacts that may be introduced, if you don't see anything, then ignorance is bliss here.
Notice I did not use the term SOE (soap opera effect) as I don't consider that to be a video artifact, but a desired functionality of CMD.
Turning on CMD also changes the colour space from 4:4:4 to 4:2:2, so if you look at the QBF pattern, recorded at 4:4:4 it will not look right, but since UHD movies use a colour space of 4:2:0. it's not an issue.
Although according to Javs, he can see a difference.
However if you're gaming at 4:4:4 with CMD on, then you will see a decrease in the depth of colour.
I don't see any noticeable difference with the MPC controls either on my RS1000, so I leave them off, it was recommenced the least amount of processing the better.
Low latency mode is for gaming, if you're not gaming, leave it off.

I would advise to set all MPC settings to 0, though you can set enhance (sharpness) to 1 or 2 if needed, but not above.
High res should be used with 4K/UHD content, standard otherwise.
I would leave CMD and motion enhance to off when watching movie content due to the artifacts they can cause. You can use CMD for fast TV sports if you like the difference.
Setting Low latency shouldn't make any difference on latency, as it is reported to be around 40ms in both cases, but it ensures that you don't have CMD on, which is a good thing.
The HDMI sync times are pretty good with theses models (around 5 secs, no more than my 4K LG monitor). What you are experiencing when switching from your SDR (iris closed, no filter) to HDR (iris open, wide gamut filter) is the added time needed to open/close the iris and to switch the filter in/out of the path.
You can improve this by using the HDR mode (BT2020, no filter) instead of the BT2020 mode (BT2020, filter). This will give you additional brightness, and you won't need to swap the filter on/off every time you swap between SDR and HDR. With a good calibration (i.e. good saturation tracking), you shouldn't lose too much color with most content. Maybe you're already using this.
Otherwise you would need to have identical or similar iris settings to save more time.
When the iris setting is the same and the filter mode is the same, your sync times should be around 5 secs, which is a significant improvement over the previous models (my rs500 needed 15-20 secs!).
You'll find lots of calibration and settings tips in the new calibration thread for these models (google the first line of my sig).
Thank you for your comments.
I am not using the P3 filter. The sync time is much shorter when there is no iris change, but still longer than Sony. With iris change, say from SDR (iris at -9) to HDR (iris at 0), it takes 10 sec or so.
I will follow that calibration thread. It should be very helpful.

I have the RS400, with much longer handshake times, but depending on which modes it is changing to or from, while the screen is black I'll hear a soft 'chattering' type sound which lasts a few seconds. I have heard others report this as well, and it seems to be something occurring in the projector as part of its changing the video mode it is using to display HDR, or changing back to SDR after displaying SDR.
I never hear this sound during actual content. During quiet scenes, when there is major action of the dynamic iris during a fade to black, or coming back after a fade to black, I have *never* heard this chattering sound, or any other sound actually.
So the point I'm raising is to try and clarify whether this particular noise, that you hear apparently during an HDMI handshake since the screen is black, represents a noisy iris, or is simply a normal part of the projector's changing video mode. If that is the case, then you may not have the 'noisy iris' issue, unless you're hearing the same thing while content is actively being played, that is not during a change in video mode.
One way to test this is to turn off the dynamic iris, i.e. just leave it in manual (for all content, all user profiles that you might be using, so the iris wouldn't be changing at all), and then see if you hear this same noise at the same times. If this is a function of the HDMI handshake itself, you'll still hear that sound.
Thank you for your suggestion. I am 100% sure it is DI noise. I might have not explained it well. When I choose a video in youtube/prime, it is not a complete black scene, there is a spinning circle indicating the player is loading the video. So there is something being displayed, and the projector is not changing display mode. It is definitely not a handshaking issue. In this scenario (no soundtrack, picture transitioning to almost black), I can clearly hear the DI working noise.
To make it clear, I uploaded two videos to show the DI noise. You will need to turn up the volume to hear it because the mic in my cell phone is not sensitive.
In the first video, I was displaying a dark background, turning on and off the menu to change the ADL to make the DI working.
In the second video, I was playing the lion king trailer, with the sound muted. There are a lot black scenes inserted in this trailer, so the DI was working hard.
I also uploaded two videos to show the video noise with and without eshift. Can anyone tell me if the video noise is normal even without using eshift?
You will need to choose 1080P in the setting to see the video noise. Even at 1080P, the google drive compressed the video, so the video noise is not as visible as seeing it in person.
To clarify it again, the DI noise is not audible when there is a soundtrack, and the video noise is not visible at normal viewing distance.
