If your display doesn’t support DV none of the options are visible in Android or CE. So I don’t think DV is related to your white screen issue.
I think it’s wrongly coded to always on in the homatics firmware.
You can find a TV with dv support for some minute, plug in and swich off the dv.

Just wondering. Did you have to do something different with android 14 to boot it from usb.. cause no matter what i try, it just wont boot.. goes to android or goes to the recovery page. Tried quite a few images including the ne and no versions. The reset button does the same. Installed the app, makes no difference.. its the nokia 8010 btw, but should not differ from the homatics..
You are probably doing something wrong/incomplete, because my 8010 on A14 boots CE21.3_NG without any problems from a 32GB USB stick on both USB inputs…
I had to switch to USB2 port for some reason and booted. Didn’t want on USB3 port (Homatics 4K+)
Every time I reboot back into ATV 14 from CE, Youtube videos play at about double speed and there’s no audio, and there’s no audio in amazon prime movies. The Homatics works fine if I boot it normally into ATV14 after removing the sub drive. I’ve tried CE versions 21.3 ne & no. Anyone else have this issue?
Atv14 sucks. Mine sometime start with Netflix, after boot in atv.
I reflashed back to atv12.
I ordered a xiaomi box gen 3 to play around with. My Box R 4K also has a bad usb 3 port so I had to get a usb/lan expander thing. I took a deal to get half the money back from AliExpress instead of shipping it back for replacement. Was it very involved to go back to atv12?
Hi All, new here. really hoping someone can answer a question I have
I need to run android 14 when I get my Box r 4k plus. or at least 12. (lossless audio support)
but I heard that you get frame skips / drops with CE on some FEL content. and only android 11 has fully smooth playback. A11 doesn’t support DTS-MA and True HD so its a no no
- is this still a thing? or is it fixed? (frame skipping in CE)
- is there any benefit to the AM6B+ for CE?. I really don’t want to go down that route as I want android certified as well. but I know it doesn’t frame skip and not sure if picture is any better
- whats the difference with all these different CE versions (NG / NO) etc. does only NG support FEL still or have things moved on
I can tell frame stutters and drops a mile off so I need to buy and know its gonna be smooth. and i can still boot android for wife friendly streaming and IPTV / emby server
Thanks all,
matt
Not all of your questions are CE related and in my opinion you could ask some of them over at the AVS forum in the SEI804xx topic regarding this device (and other almost equal devices).
Purely speaking of the CE part, the main benefit for CE usage (NG that was in the beginning), for the R Plus, is that you would get Full HD audio and working auto framerate support also with Android TV V11 on the box, with CE to be clear. It was implemented for Android TV at a later moment after a certain Android TV V12 update.
For FEL support you need to use a NG build.

So, this happened for me. Should I prepare the usb from scratch, or is there something I could try with current installation? I have CE NG, latest nightly I guess, on the Dune box, seems like the booting process degraded gradually, but the usb drive should be fine, it’s quite new samsung fit drive 64GB.
Sometimes it hangs on starting services, update-bl301.service, wsdd2.service
Using usb3 port seems to have improved things. But I liked keeping the CE usb in the USB2 port, to save the USB3 for occasional external HDD use as source for playback. Can the USB2 be failing slowly? Is there a way to check this? 
P.s. sorry if my picture breaks the display grid of the forum, I can remove it
In your case I would still use the USB3 port and the USB2 port for connecting your storage. It should be fast enough for data distribution (playing media), and with using the USB3 port and a fast USB storage, you get a nicer CE usage overall.
I bought a usb 32 because with 128 or 8gb i was not able to start it. I have homatics 4k pro with android 14 and i have everything now after boot it : vs10 , fel 7 .
My home setup is bravia 9 65xr90 , x4800h Denon , 5.1.4 and homatics 4k pro with coreelec vs10 and fel.
Depends on the brand and model I guess, as I use 32/64/128 and even 256GB USB storage for CE with this device (and ATV V14).
Currently one of the most fastest ones I guess. SanDisk 128GB Extreme PRO 3.2 Solid State Flash Drive with 420 read / 380write MB/s

You’d be lucky to get 150-170MB/s read-write over USB3 on an s905x4. I wouldn’t spend a lot of money chasing ultra fast USB Sticks and SSDs.
Do a read/write test in CE to get a real idea of transfer rates.

I compared several sticks and choose the one that gives me the best results on usage. And although you can’t get the speeds what it theoretically can do, there can still be a big difference between them, speed wise. But what I really replied on is that size doesn’t really have to matter, ignoring the speed the storage has. You saw that reply above mine, yes?
It doesn’t make much sense sharing info about a device without adding its specifications 
I’m using SanDisk 128 GB Extreme Pro and SanDisk 64 GB High Endurance microSD cards with a USH-II Kingston card reader (this reader is very compact and extremely fast, being UHS-II) and the only reason is durability. Very large storage ensures that only a small number of cells get used daily as the microSD is mostly empty (CE and a handful of small add-ons) so they’ll last longer.
Also, using 2 microSD cards in an A/B like system allows to perform upgrades, with a bit or RSync magic in between, with a immediate rollback backup and ensures some load balancing on the wear level of each microSD card Finally, as a bonus, the upgrade process takes only a few seconds upon reboot as the storage is really fast but I don’t update that often for it to be important.

I tested a couple USB drives on the s905x4 1-2 years ago.
CE-NG
Samsung BAR Plus 3.1 256GB (advertised 400MB/s)
Windows - 400MB/s read
CE-NG - 75MB/s read
SanDisk Ultra USB (SDVZ48-256GB - advertised 133MB/s)
Windows - 130MB/s
CE-NG - 130-140MB/s
I had noticed a change in USB3 speeds in CE-NO on another SOC, so I retested these two sticks in CE-NO today.
CE-NO
SanDisk Ultra USB - 130-140MB/s
Samsung BAR Plus 3.1 - 310MB/s
There is an improvement somewhere in CE-NO that greatly increased performance for the Samsung stick. This is a bit surprising, before I’d assumed there was a ~200-250MB/s bottleneck. eMMC read speeds on the s905x4 are ~130-150MB/s, so with a decent USB drive you’ll get considerably better performance than an eMMC install.
The point I’m trying to make is, don’t rely on the advertised transfer rates, or Windows benchmarks. Do a read-write test in CE, and results may differ between CE-NG and CE-NO.

Thanks for posting this. I can confirm the Samsung speed on CE-NG on my 128GB stick. Very surprising to me. I’m going to purchase the Sandisk and see whether I get better performance.
Do you think a smaller capacity stick would be as fast? I know there are differences based on capacity in general, but I’m not sure how extensive those differences may be. Regardless, it’s a cheap enough experiment I suppose.
