If you are still facing issues try this : http://www.ddcutil.com/nvidia/
This worked for me.

Leonid,
I see you've closed the issue, but for future reference what's key in
the diagnostic output is that i2c slave addresses x50 and x37 and not
present on either of the 2 /dev/i2c-n devices. It's also odd that there
are only 2 - normally there are many.
I suggest you download and install i2c-tools, which provides command
i2cdetect. "ddcutil environment --verbose" will use i2cdetect if
available. More importantly, you can use i2cdetect to see if there are
any i2c buses having both slave address x50 (EDID) and x37 (DDC)
active. If not, there's nothing that ddcutil can do.

Thank you. Will do and reply back, but within 1-2 weeks.
Currently everything works with latest nvidia drivers, and HDMI cable. (So my best guess that problem was in bad nvidia update plus the whole system not working with displayport for some reason, because I remember I switched to displayport, and only then started to try different drivers.)
So what I am going to try is to switch back to displayport, and provide the log in case it stops working again.
(I presume brightness control (DDC communication?) should work regardless of cable I connect monitor with.)

Again, I suggest that you use command i2cdetect from package
i2c-tools. Its a quick way to check if slave addresses x50 (EDID) and
x37 (DDC) are present on an i2c bus. Unless they are, ddcutil cannot
communicate on the bus. If DDC communication is working, then there's
nothing special about VCP feature code x10 (brightness). I've yet to
see a monitor that doesn't support that feature code.

(i2c-tools package installed)
just in case, I attach output of "ddcutil environment --verbose" for the current setup (HDMI cable, nvidia-387, where currently everything is working fine)
sudo ddcutil environment --verbose
Output level: Verbose
Reporting DDC data errors: false

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***
(identify_i2c_devices) Identified 2 I2C devices
Checking /dev/i2c-* devices...
Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).
Typically, this access is enabled by:
- setting the group for /dev/i2c-* to i2c
- setting group RW permissions for /dev/i2c-*
- making the current user a member of group i2c
Alternatively, this could be enabled by just giving everyone RW permission
The following tests probe for these conditions.

(Will attach same output of all the commands when I switch back to displayport and thus probably reproduce the issue.)

ok, I restarted computer today since then, and the issue came back.
I copied a file to /etc/udev/rules.d, one binary to read usb light sensor to /usr/sbin and a systemd service wrapper, then restarted system again - and ddcutil was still working fine.
I did one more (third) restart, doing nothing other than opening the browser - now it says again Failure getting EDID for /dev/i2c-1: status code=DDCRC_EDID(-3016): invalid EDID
output of sudo i2cdetect 1 and sudo i2cdetect is the very same as in the comment above - 1 month ago (did diff comparison with vim)
@rockowitz, can you please offer an advice in further debugging?
From a blackbox point of view, I can only guess that my system has something non-deterministic in the load order such that sometimes ddcutil works, and sometimes doesn't - because copying files and running this tiny systemd service (and also deleting /dev/floppy0 from my /etc/fstab) was literally the only change between these three restarts, and there was no changes other than running google chrome between second restart (ddcutil worked with no errors) and the third one (ddcutil gives an error).

edit: actually, I do not see I have posted original error message of ddcutil in this ticket, which is not good, so I cannot compare current error message of ddcutil to something above.
Redoing steps from man on nvidia drivers now, and modprobe commands from above, because it looks like #30 and not like something that was in this ticket. Sorry for confusion

I just did one more restart, doing no changes whatsoever, and it works again. The workaround for nvidia in xorg.conf.d was there all the time, of course.
So it's something to do with the load order or something else. (Something something dark side.)

Leonid,
My best guess is that it's an issue with the proprietary Nvidia driver,
which we know has problems, particularly for newer cards. If you can,
try switching to nouveau, at least temporarily, and see if the problem
persists.
Status code DDCRC_EDID indicates that the bytes read for the EDID do not
represent a well-formed EDID, probably because
the initial marker bytes or the checksum are invalid.
If you're running ddcutil 0.8.5, you can execute ddcutil with options:
--trcfunc i2c_get_raw_edid_by_fd --trcfunc i2c_get_parsed_edid_by_fd
This will give you a look a the EDID bytes and may give a hint as to the
nature of the EDID corruption.
