Having trouble with the x470 chipset bios update with windows 10 v1803. Updating from P 1.10 to P 1.40, can download files and run software. Ask for permission to reboot which is supposed to initiate the update, but nothing happens. Just goes thru the normal reboot back to windows. Their instant flash also does not work and their tech support suggested the windows process.

I'm not suggesting the monitor is defective, i'm suggesting your display settings in Windows 10 may not be set correctly to work with your monitor.

no and I have disabled virus protection with no success
 

It may be easier for you to update the BIOS from a flash-drive rather then updating through Windows.
 


Have tried that with the same results. Also there is a note from the mfg that the uefi flash function does not work yet for the x470 chip set bios and to use the windows approach. Also it looks like I have a bad hdmi port on the MB according to their tech support.
 

Are you certain the update was not successful? From my understanding when you start the BIOS update batchfile in Windows, it will flash the BIOS and when the flashing is complete, the system will then reboot automatically. Everything is done in Windows before the reboot.
 

In your original post you stated "you download the BIOS files and run software. It ask for permission to reboot which is supposed to initiate the update, but nothing happens. Just goes through the normal reboot back to Windows". As i said earlier, from my understanding the BIOS update is done in Windows before the reboot. When you ran the batchfile, did nothing happen before the reboot? The link below is a quick ASRock tutorial on updating the BIOS in Windows.

Finally, ignored the ASRock tech and used the uefi instant flash and a thumb drive and updated to P 1.40. However, still did not solve the primary problem of windows 10 recognizing the onboard hdmi Vega 8 adapter. Now with the new bios installed, Device Manager does not even see a Vega 8 adapter and the hdmi port remains non-functioning.
 

Are you using video card at the moment and the onboard graphics is not working?
Have you booted without the graphics card and the HDMI still does not work?
Can you list the parts in your system?
 


 
Have not tried booting without video card, but will take a look to see what happens. System is ASRock Master SLI/ac bios P1.40, RX 560 Radeon video card, Ryzen 2200G, 16gig ram, drives consisting of m.2 card, ssd , and 2 WD mechanical drives. No signal coming from the onboard HDMI port and no listing for it in Device Manager. Main monitor in the HDMI port of the card and the second monitor is using the DVI port of the card with a dvi to hdmi cable.
 

Have you upgraded all your motherboard drivers?

AMD all in 1 with VGA driver ver:17.40.3602_WHQL [2018/3/23]
*Ryzen 2000 Series APUs(Raven Ridge)
 
New motherboard made no difference. My display driver is a 24.20.11016.4 for the RX560, with no display adapter showing for the onboard hdmi port. Tried pulling the RX560 and booting with just the onboard hdmi and I got a boot, so the problem is not with the port. Put everything back in the the onboard hdmi display adapter goes away. Looks like conflicts with the board, the RX560 and/or Windows 10.
 

What about your monitor. What model is it? Right click on your desktop and choose "Screen Resolution > Advanced settings". Make sure your monitor is selected as "Display". Also make sure your resolution and screen refresh rate are compatible with your monitor.
 

I'm not suggesting the monitor is defective, i'm suggesting your display settings in Windows 10 may not be set correctly to work with your monitor.
