Same problem here:
Motherboard: J4205-ITX
AV receiver: Denon AVR-3808
TV: Samsung 46F7000 (1080p)
Post Bios boot: ok
Loading windows 10: ok
Windows 10 login screen: no signal video
No change if I connect directly to TV or I change HDMI cable
And this only if I use HDMI output, while if I connect to DVI output it works properly
I've temporarily fixed the problem in this way:
1. Turn off the system
2. Unplug power cable
3. Wait 15-20 sec
4. Reset Bios by jumper on motherboard (not via software within the bios menu).
To do this change the bios reset jumper CLRMOS1 in position 2-3 and wait 5-10 seconds; after put it in position 1-2 again
5. Plug power cable
6. Turn on the system
Before enter in the setup bios wait for a complete boot and windows loading to see if the login screen appear on monitor/TV .
In my case for example when I've turned-on the wake-up option by USB keyboard the problem it's come back again and I've to repeat the procedure again.
A workaround could be to bypass the login screen of windows 10. In fact, at least in my case, the lost signal is only in that screen. If I login after desktop is loaded the screen come back online again.
To do this you can use the command line "control userpasswords2" to setup an automatic login.
However, this is at 100% a bios problem and I hope that ASRock will fix it very soon.
I hope that this post could be useful, and sorry for my bad English
