I have a nuc N3150 (braswell) with a tv hdmi 1.3 and an avr hdmi 1.4 (denon )

I want to change cause with this setup i have many blackscreen (handshake ? ) issue during refresh rate change

tried solution like forcing custom edid (with forced 8 bpc and forcing inteface) but only solution is to change hdmi input from remote tv

Tried via hardware with dr hdmi...no way

Could someone with a more recent avr (hdmi 2.0 ) and a more recent nuc confirm that doesn't have this bug ?

I want a confirm please before spend other moneys

thank you

Ps:Why intel doesn't have it's own section as rpi etc ?

mmh i do some reverse engineering

deleted edid via command getedid delete

without edid i verified via dmseg that bpc is always set to 8bpc (several restart with avr on or off)

Verified during black screen problem that bpc was 8 (via denon menu)

Found out that if i switch hdmi via remote tv (hdmi1>hdmi2>hdmi1) kodi gui reappear

so seems that my problem is not due to bpc bug

i'm using Milhouse Intel nightly build 19 and for several plugin only need to edit addon xml if already ready for python 3

Amazon vod , audio script profiles, aeon nox kodi for example just need to edit addon.xml

Ok update for community

Problem : with autoframerate switch I get black screen on start or stop of a film

Denon x2000 HDMI 1.4

Tv Panasonic vt60

HDMI cable expensive and tried other cable

Beebox Intel n3150 but I didn't remember if Chromebox had this problem

Read somewhere that the problem is an hardware bug of Denon

Solution tried:

Captured edid

Modify edid to force 8bit

Checked with dmseg that bpc was set to 8

Checked via avr that bpc is 8

Still have problem so cause is not waf compliant I set gui to 24 and leave autoframerate switch on

Probably not a good solution but is the best solution until I will change my avr

Seems to be cause edid.cpio contains newedid.bin parameter

thank you for all

i followed manual guide

Custom EDID [LibreELEC.wiki] from point

Next a cpio archive file will be created which will be loaded at boot:

to create a new edid.cpio

but some commands give me error

at Search for “extlinux.conf” or “syslinux.cfg” and edit it. Only one of them is available.

seems that the parameter -w doesn't exist cause it ask to check the valid parameter for nano

I edited my edid file to drop 10 and 12 bit and avoid black screen issue with Intel graphic card and denon avr

see here for info:

Occasional Refresh Rate Change Problems

Original edid was created using getedid script, i edited edid file with 8 bit flag

And now what are the steps ? i suppose that i must edit also edid.cpio file and is not enough to overwrite edid.bin file in /storage/.config/firmware/edid

Btw unlucky this patch didn't solve broadwell/braswell refresh rate issue (black screen)

I know that this was a patch only for Gemini but "hope is the last to die"

Also for me sky42 and milhouse thank for your hard work

btw i found also this bug with avr

Occasional Refresh Rate Change Problems

(but in my case i get only black screen not unsupported signal)

edid sorry for my ot

Quote from laric

I get it to work on my old 1080p plasma but no image on my brand new 4k qled (QE65Q9FN )

Any log or something I should get out of the system as I get ssh acccess but no picture after the uefi boot screen?

cause sometimes ago i also had coldboot problem a developer teach me to append to custom edid autostart also the resolution and refresh rate at autostart but i'm sorry i'm not able to tell you

so i have a string like that

BOOT_IMAGE=/KERNEL boot=LABEL=System disk=LABEL=Storage ssh quiet initrd=/edid.cpio drm_kms_helper.edid_firmware=HDMI-A-1:edid/edid.bin video=HDMI-A-1:[email protected]

ah sorry i forgot to post what i use

software solution

Audio Profiles - Easy switch between different audio settings (that can also auto switch from avr mode to tv mode )

i toggle tv to avr via remote key mapping

so your avr is always on ? or you set action to harmony ?

Like: Tv series only audio tv..... avr switch standby

Like : film avr switch on

But how do you switch ? for audio i use

btw i forgot to say that i found this bug also on rpi forum

BUG: Black screen when returning after watching in 23.976hz.

Quote from porkchop999

I still get a black screen on switching. If I set the Kodi gui to 30hz there is no problem. This only seems to happen on 1920x1080. There is also no problem if the Kodi gui is set to [email protected] .

Same (in my case) for my braswell and broadwell Nuc in combination with AVR

Someone on Kodi forum almost 18 months ago said that was an issue caused by AVR (onkyo or Denon) and I found other users with AVR and same issue (something about clock delay due AVR passthrough )

After many months of bad WAF (everytime a blackscreen =force reboot) i read on libreelec forum that a solution was to force gui to 30hz and now I found this thread with same issue and same solution works

So probably is the same bug ?

Semi ot

23.98 refresh rate solution is only for Gemini architecture or for all Intel architecture ?

I ask because me and many other users have this bug in combination with AVR

Only solution set Kodi GUI at 30hz

If I set 50, 59.94 or 60hz I get black screen switching back from 23.98

This problem occurs on chromebox with broadwell and on braswell

Yes please post a video,if you have time, cause i'm curious

In my case i have black screen (no i don't lost signal) after peter anvin et al boot message or kodi logo

I forced AVR Edid cause in xorg log there was a mention about hdmi lost signal /disconnected (not exact error but i don't rembember now)

lucky these problem with my avr happens only with kodi (tried a chromebox and nuc with braswell thinking about hardware issue)

23.98>50/60 refresh rate switch is another bug

Black screen on play when refresh rate switching is enabled

You are lucky because with my Denon avr (but other users with onkyo) have this problem also with Kodi 17

This problem happen less since I forced edid

And also me and other users have black screen when refresh rate changed on play/stop

This issue finally solved forcing GUI at 30hz.. , found it after almost year of pain just fews days ago

(and probably this solution solved also black screen at boot)

These issues was so frustrating and not WAF that I mapped a remote button for hardware reboot

Found this solution even if is for Raspberry
