2- boot the computer - I wait enough to be sure that that windows 10 is at the login screen
3- start the TV
4- connect the HDMI cable.
Then everything works perfectly.
However, if I restart the computer, then no more HDMI signal.
The same occur if the TV is stopped for too long.
The only work around is to shutdown the computer (I hold the power button 3 to 5 sec), disconnect the cable and proceed as explain above.
I took the decision to return the card bought on amazon and hope that it is just a problem with this card.
But, I have actually some doubt as everything works wonderful when the HDMI is well detected.
By the way, I tried with 2 different HDMI cable 
In the meantime I put back my old ASUS A3-ionT deluxe that doesn't this issue.

If you have any idea how to fix this ?
Is it a well known issue ? Is a fix in preparation ?
Should I consider another card to get the 4K decoding ?
Thank you for your feedback.
Vincent

this is exactly the only way it works for me (and this is not realy an acceptable workaround)......two month later and no fix...are you working on it @asrock?

It's worth a try to update your LSPCON firmware to 1.61... (my J3455-ITX had 1.56)
You can get it here: http://www.asrock.com/mb/Intel/Fatal1ty%20Z170%20Gaming-ITXac/?cat=Download&os=All

I had to change (add //) the config.ini file so that it can detect the address of the chip:
//DeviceID=0x0f

Warning, when flashing my screen went all green, but came back after 10-20 seconds.

Then shutdown windows and power on again.

Well yea. But until Intel supports CEC I wouldn't be holding my breath waiting on any support for CEC out of LSPCON. Or at least I don't believe it can be made too anyways.

I'm more interested in who has HDMI-CEC enabled on their screens. As it's a universal/blanket issue/reply command and cannot be selectively "directed' by the screens input port, ie: all ports or no ports, on or off, if this might be partly at issue here.

Curios question to you all here.

How many have HDMI-CEC enabled on your televisions to accommodate, say, a stand alone BD player, being able to turn the screen on via CEC w/o interaction by you having to manually turn the screen on?

Hi, I have the J3455-ITX and was surprised about the invisible HDMI W10 boot too.
What works for me is turning on the TV as late a possible, at the login screen or just after. Confused
I've never had to disconnect the HDMI cable.
Hope ASRock can fix this...

@vienna
Officially the only OS supported by ASRock for this motherboard is Windows 10 64bit
I've installed only Windows 10 and I don't know if there are drivers for Windows 7 or Linux Distro.

In my case as I wrote, the problem about the lost signal on windows 10 login, come back if I enable USB Keyboard wake on line, but I repeat: in my case.
I've fixed it with the hardware reset procedure, and now works properly, but I don't use wakeup function.

The performances of this product in my opinion are not in the j4205 itself but in the HD 505  that can play video HEVC 10bit in 4k resolution.
Otherwise, you can always buy a motherboard mini-itx, and a CPU but it is much more expensive (always if you need hardware decoding for 4k).

[URL=][/URL]@Ful
Does it mean that WOL (activation per wlan, lan, app form phone, etc) is not working properly too, as you reported about wake-up troubles due to usb devices?
Hdmi main slot out will not get a handshake after wake up from hibenration state?
It is a bad news for me, I am still not completelly convinced about performance of this MB, thinking about getting one of them for my HTPC.
Did you try to install w7, or/and ubuntu 16.04 too?
Many thanks and best regards from Vienna
