No 4k output in system

[Hidden32]

Hi,

Ive had my panasonic plasma TV for years and its obviously a 1080p TV so no issues there but a couple of days ago I bought a new TV LG C2 OLED 4K TV and Ive changed the reso to 4k in display settings but thats just about it, the system still believes Im running 1080p reso! Wtf? In cpu-z it says system resolution 1080p, in kodi I cant even choose other resolutions besides 1080p so no 4k reso and Im not talking about the GUI reso but the max reso to play media. All videos and streams/links play in 1080p even when I select a 4k link. The minix u9-h should support 4k reso but mine doesnt even though I have changed in display settings. What gives? Why is my 4k reso a fake 4k reso and in reality only 1080p? I dont know what to do. My TV has 4 hdmi 2.1 ports. Everything else runs at native 4k so the tv itself, my xbox series s, my tv decoder besides the minix box it runs only at 1080p no matter what reso output I choose. The system "thinks" that my reso is 1080p. Why and how? This is not normal. Im running the latest official firmware version. Can anyone help?

Hi,

... The minix u9-h should support 4k reso but mine doesnt even though I have changed in display settings. What gives? ...

Hi Hidden32,

The U9-H is a 4k HDR capable device. It should be fully compatible with your TV. At the screen definitions you should have the line above all: "auto switch to default resolution". Set it to ON so the box detects the best TV resolution itself.

The CPU-Z display info refers to the Minix box interface as well as the resolution info in Kodi concerns the Kodi interface only. To test the 4k content: start by checking that the box picked automatically the right resolution from the TV, it should have picked 4k, and then either download a test file (https://4ksamples.com/) or get an app capable to play YouTube content in 4k such as SmartYouTube (https://smartyoutubetv.github.io) and check it from there.

Hmmm so this is normal on this box? Yeah Ive already enabled the auto switch to default reso. I always enable that setting.

But how come when I play a movie on kodi and I go to media info I see the reso or display output in 1080p while its a 4k source? Thats whats bothering me and it clearly is 1080p. I notice a big difference right away. Maybe the u9-h has issues with hdmi 2.1? Also how come I can enable 4k in windows on kodi? The option is actually there in display settings and also in whitelist reso I can select 4k reso with all the different hz 23,98, 24,50,60. Again thats not the GUI reso but the actual reso output for movies and tv shows. On the u9-h in kodi I have only 1080p in whitelist with all the different hz.

Im not sure the reason why you are having issues.

I have an LG C9 oled 4k and had no issues when using it with a Minix u9 in playing correctly 4k media files .

I can only suggest you double check all your settings or possibly factory reset your u9 to see if that corrects your issue.

A lot is said. It seams the Android OS has a limitation regarding the Apps Gui.
Nevertheless, 4k will play at 4k. The reason I mentioned SmartYoutube is because you can easily use it to check several resolutions of some Youtube 4k content and see for yourself that, in spite of your TV eventually automatically upscaling the lower resolutions, there is a huge difference between 1080p and 4k content. That is easily noticeable.

The above two images show a 4k Youtube content on a 4k TV, using a U9-H and a U22-XJ. It seems that's as good as it gets. If your U9-H is connected to the TV with the correctly detected 4k res, that should be ok.

in one of those links someone wrote this and its just as I thought and I was right! Whitelist reso is the actual video output in kodi. Its locked in 1080p and there is no 4k.

Quote: Kodi can downscale 4k to 1080p and still give you HDR. If the whitelist is locked at 1080p, that's what you're watching. The 4k you see for the movie is just the movie's information, not your display info.

Quote 2: If you select the video settings while playing a 4k movie and go to Video Calibration... it'll give you the resolution being displayed.

I did that and it shows 1080p. Thats what I wrote in my first post ? and you all are giving me including that mod/admin who deleted his and my post, that its normal its kodi's GUI blabla while all this time Im not even talking about GUI bur the actual video output and you all dont seem to get that ?

Quote 3: Thanks, I did what you said (when watching 4K-content > Settings > Video Settings > Video Calibration and it does indeed show 1920x1080.

Quote 4:
Your tv only supports a 1080p frame-buffer, that's what Kodi uses.
Check if you can enable all the 4K and 1080p resolutions in Kodi's System-Display-Whitelist then videos will switch to 4K resolution when they start playing.
If you only have one option here then your tv manufacturer, Phillips didn't implement the Android Mode Setting API that was released since Android Nougat and you have to contact them for a firmware update to fix the issues.

Again only 1080p available and video output is 1080p.

So conclusion: minix u9-h has issues with LG C2 OLED. Solution: buy a better android tv box just for kodi ? because im only using this box for kodi. My TV doesnt have kodi in apps.

Or maybe a cheaper option/solution: install kodi on my xbox series s ?

I was not aware that a mod/admin had been trying to help you on this subject but since you are still a member of this forum (and as long as you are you will likely get interaction from other members) I presume whatever caused the dissent was not too serious. As you can see from the Kodi forum you are not alone, that is actually my point, but you can also see this so said issue is not singular to Minix boxes, as far as I know there is one single brand that doesn't have that issue but it is an Android TV box, which also has issues by the way.

Better is alway possible. Sometimes you should follow no one but yourself to get what you want, that's for sure.

Yeah an admin replied and I thought he was with minix (I was ranting about minix how they suck and their devices suck etc) but he said that he's just an end user like me. I was angry and frustrated with his reply because he didnt seem to understand my issue. I wanted to apologise after I saw his 2nd reply but I didnt get the chance since he already deleted my post and his posts. So whoever you are admin (sorry dont remember your name) my sincere apologies.

Well Ive read in one of those topics that someone said that with coreELEC you dont have this issue, you can actually select 4k in whitelist and the video output is 4k and he used a minix device. So it def is a minix android issue meaning an OS issue and not a kodi issue.

Quote:
I guess there is no need tor rant about TV manufacturers because the stock android TV platform does not support 4K resolution in the Kodi app.
I have a Philips OLED, an Amazon Fire 4K stick and a Beelink GT King. NONE of them support 4K on Kodi Android app. If I boot my Beelink GT King to CoreElec, Kodi runs perfectly 4K HDR, even the GUI is 4K.
It´s the Android TV Plattform, not Kodi or the HW.

So maybe I will try out coreELEC since I'm using only kodi on my box, thats still easier than to use kodi on my xbox lol.

@Hidden32

You are wrong about android tv.

I had one nvidia shield tv (KODI GUI is 4k)

Android TV and standard android are diferent (similar but not the same).

My MINIX Experience:
-Only x86 devices have Kodi GUI in 4k (example ngc-5), tested with linux and windows
-All android devices that i tested have kodi GUI limited to 1080p (example U22-XJ) , did not test CoreElec, just official and custom ROMS.

Im not talking about GUI reso but actual video output ? No im not wrong. Read all those kodi links that guy has posted and read all the quotes that I made from those links.

Mod Edit: please keep your replies civil, as frustrating as it may be some people do indeed fail to read but is better to ignore it than respond to it.

You can try coreelec.
Whatever is most suitable for your needs.

CoreELEC solved the issue ? Im so happy. Now I even have HDR and dolby atmos on kodi and ofcourse 4k video output woot ?

The performance is amazing. Its atleast 3x faster vs minix android. Scrolling through and opening menus, options, lists and playing video is instant. No delay, no freezing, no lagging. Its amazing.

Now its using the full power of the minix box. Minix could learn a thing or 2 from coreELEC, to use a linux based OS for their minix boxes. You need pretty high specs for android to be fluid and fast. Atleast 6 gb ram, a faster and better cpu and thats what all minix boxes lack of. 2gb ram is way too low for android.
