This is not normal, I don’t know what you have done.
The HDR issue can be resolved by running the following command from SSH.
fw_setenv sdr2hdr 0
Adamg, this is out of the box, just arrived to me. Powered with Amazon`s Echo Dot power brick, plug in with certified HDMI to the AVR and tried to run some tests and movies:
Remote controller - working fine. Even the smart remote of my Q9FN is working
1080p - not able to play - movie starts, but then playback stuck, then resume again and so forth…
4k - not able to play - same situation as 1080p
All content seems to be in forced HDR - will try to fix with the command you gave me
HD sound - not able to play
DD and DTS sound - working fine
Sound when in GUI - working fine
Its like the sound passthrough is forced to go to the SPDIF instead to HDMI
Then, what about TruHD and MA passthrough - is there another command?
Isn’t Alexa a virtual assistant ??
Never heard of a product named Alexa Power Brick.
True - powered with Amazons Echo Dot Gen1 power brick 
but thats not the point
All issues were fixed after updating to Nightly_20191222:
- No inverted colours after the update
- No forced HDR
- Original remote does not work, but my Samsung Q9FN smart remote is working fine
- 1080p smooth play
- 4k HDR and HDR10+ smooth play - tested with movies and some demo videos
- HD audio passthrough is working fine
Needed to turn on “Disable GUI scaling” otherwise the display was zooming when in 4k and cropping when in 1080p.
to fix zooming, cropping correct way below:
Next Nightly will sort out amremote as long as you copy and paste remote.conf into .config folder.
Hello, are there any improvements compared to the stable build 9.2.1?

back to 9.2.1, works fine.
Reboot and post a full dmesg log.
Please try this DTB and let me know if it works.

Tried, but no luck…I stopped kodi, I deleted the whole /resolutions/ section in the guisettings.xml and when I switched to 2160p, I got the no-signal screen (like there is nobody at the HDMI port) but after 5/10 seconds it got back to 1080p.
Secondly, when I try to play 4k I am getting, again, the no-signal screen and then I have to stop/start kodi (or reboot) in order to get back the image on screen.
Do I have to switch back the “Disable GUI scaling” option?
I am now running on Nightly 20191223, this was not observed when I was on the previous build.
It’s probably a bad HDMI cable that can’t handle the bandwidth of 4K.
Thanks, Replaced with this dtb file, it works.
Thanks. The fix will be in tomorrow’s nightly build, so I you don’t need this experimental DTB anymore.
After updated to the last two day’s nightbuild, I still need to replace the “dtb.img” file to make vfd working.
Sorry, the repo wasn’t updated with latest kernel changes. We’ll do it for tomorrow’s build.
hello,@Blakey).I have coreelec 9.2.1 version installed on VIM3 pro,memory display is incorrect,Is there a document teaching how to upgrade uboot to fix this problem?thx
With 20191230 nightbuild , VFD works Fine.thank you !

Upgrade Android to V191101 https://dl.khadas.com/Firmware/VIM3/Android/ with USB Burning tool (https://docs.khadas.com/vim3/UpgradeViaUSBCable.html) and everything will be okay.
