Now that users have started to receive their N2s, it’d be great if someone with a HDR10+ TV could check if it works or not.

@Sholander I just fixed the poweroff USB issue you reported. Will be in the next build.
Now it’s 0.7W on suspend
1.1W on poweroff. All with WakeOnLAN enabled. I still don’t understand why poweroff uses more lol
Without wol it’s 0.3W powered off. And 0.2W in suspend.
So either way I again recommend suspend because it works good, it’s instantly on or off and uses less power than poweroff.
If WakeOnLAN is disabled in boot.ini with "setenv wol “0”, then I did that already; so only 0.2W in suspend 
To disable CEC do I have to change "setenv hdmi_cec “1” in boot.ini to "setenv hdmi_cec “0”?
I realy don’t need nor use CEC…
Tnx for this explanation.
Yeah. Remember boot.ini is overwritten on update. Use config.ini. You can disable cec too. It won’t save power though.
Just setup the 4.7.19 build on 4GB model. Left the whitelist display options all deselected, enabled passthrough audio on all formats. (Both TV and AVR are capable of all those settings)
Auto resolution switching worked as expected. HDR10 files automatically displayed and switched resolution (I left the default 1080 gui as suggested which defaults to 59hz). I did notice stuttering in all 23.976 4K content both HDR10 and SDR. As mentioned, there is also stuttering in 59hz and 60hz as well.
EAC3 audio on ONKYO receiver would not play. AAC stereo audio would not play even with stereo upmix off.
Setup was flawless, and the device feels noticeably faster than the C2. Aside from the stuttering video and few audio format limitations, everything else seems very promising. Happy to help with logs or testing for HDR10 video.

DD+ seems to only work with some equipment, we’re still looking into it.
We are ironing out the remaining stutters. For HEVC content use the workaround setting in CE System settings. Subs stutter is fixed. And 60fpa issues are being worked on.

yes, I meet the remote’s issue too.especially when a media is playing. (I use estuary mod v2 skin)
The videos appear a little bit cartoonish. They appear to have too much sharpness.
I also see a lot of stutter in almost all videos I play. The playback is not as smooth as S912 box.
I meet the wired thing, N2 connect to PC monitor(1080P) via hdmi cable, Playback videos(HD and UHD) no stutter, skip: 0, VSyncoff: 0.0, but when N2 connect to TV(via the same hdmi cable), stutter happened on all videos, skip: numbers increase and VSyncoff: 10+，Who can explain this? switch to odroid c2, no such wired thing.
I think my TV is capable of hdr10+. How to test? Sample file?
Colors also look a little bit weird to me when comparing with my s905.
Also I was wondering why on this powerful hardware I still see lags during the playback when jumping around in the Kodi menu?!
Absolutely no criticism from my side, I’m just interested.
If you are talking about HEVC videos, you need to enable the HEVC seek workaround in CE System settings.
@rosenrot Yes, a HDR10+ sample.
What storage are you using? I don’t see any lags.

I do use a recent sdcard for the moment. I will give a try to emmc soon. I had the plan to use the n2 as an ubuntu server running kodi besides. However, it seems kodi running on ubuntu is not quite ready yet. I was playing around a bit with it but it seems hopeless for now so I will use the emmc for coreelec soon.
@rosenrot, here is a HDR10+ sample you can try https://drive.google.com/file/d/1Nz2MPf2FPz3A99ciBSAl3m0U0XBbV1bv/view
Remember to run the test sample both on your N2 and your TV’s internal player to try to see any differences in quality. Also post dispinfo during playback (ssh into your box and run dispinfo)

If you can play your stuff on one Monitor but not the TV it probably means that you are playing in the wrong refreshrate.
Now that you mention it I’m seeing that too.
Lol. You guys got used to the bad 3.14 stuff 
It is suppose to be that sharp. Compare with a Intel box.
I don’t think so, because I use the same N2(settings no change) / net cable / HDMI cable / PSU , Only monitor and TV difference, Why stutter on TV not on monitor, I can’t figure out, I will try another TV this weekend to see any difference.
Working really well thanks for this OS it’s really great.
One thing I noticed is that using the official Odroid wifi adapter also referred to as “WiFi adapter 5” on hardkernels site was unable to connect at 5ghz but 2.4ghz works fine.
The 5ghz connection works on Android and Ubuntu, just not CoreELEC, but I’m not too fussed as I can still connect using 2.4ghz and don’t need the speed really, I was just wanting to mention it.
The interesting thing is it saw the 5ghz SSID but it didn’t want to complete making the connection.
There are some videos I still cannot play, but I never have been able to play them on Android either or the Odroid C2, yet they play fine on VLC on Android on the same device. I think it’s a Kodi bug on ARM only, it just doesn’t start playing at all for those videos and returns to the menu. I don’t think it’s a CoreELEC issue so will try to send a bug report to Kodi.
