Oh I see, it may be related to using a TV. Yes, I was hooked up to my Sony TV via a Yamaha receiver, both around 7-8 years old, as they were most conveniently available where I was testing the system. Since my post I've found people mention Intel integrated graphics and some poor HDCP implementation.

Works fine with the nVidia graphics.

Fast boot is disabled by default from what I can see, and I haven't changed it.

Intel seem to put all responsibility on the motherboard vendor for these issues.

Is this something Asrock has fixed in the past, or will I just have to live with it?

At first I got only to boot code A2 during boot a bunch of times, regardless of having my SATA SSD connected to various ports or not at all. Tried reseating RAM, one stick at a time, resetting CMOS etc. After trying them all in different slots, I slot in my nVidia GTX 970, and now it boots.

With the discrete GPU I can access UEFI and I enable concurrent iGPU. From Windows 10, the Intel graphics works once I install the drivers.

After removing the GTX 970, however, I'm still not able to get any display output for UEFI from internal graphics (I've also tried this without having enabled the concurrent iGPU setting), or see anything before the OS loads it's drivers. Only after Windows loads do I get any output.

UEFI is 1.10 out of the box, which is the most recent non-beta release.

Smells like a UEFI issue. Is this forum the correct place to report this?



Yes this is a good place to report problems like this. As well as report it to ASRock's technical support:

https:///event.asrock.com/tsd.asp

This is the first report of anything like this with any ASRock Z370 board.

Usually no apparent video signal until the OS boots occurs when using a TV as a monitor, via HDMI.

What are you using as a monitor?

Did you select the integrated graphics with the Primary Graphics Adapter option in the Chipset Configuration screen, when only using the iGPU?

Are you using the Fast Boot option?
