H670M Pro RS no HDMI signal

   Hi,

i've bought a H670M Pro RS mainboad, powerd by an 750 W Thermaltake, an 16 GB Storage CT6040FRA32S, Intel i5-13600K.

After power on at button the CPU Fan works, but there is no signal on the HDMI port.
One of the 4 LED on board is lightning red.

I also tryed other storage KVR32N22D8/32 with the same result.

The monitor is checked by another PC also the cable. Also I tryed an oter monitor and another cable.

Can anybody tell me how I can find the error?

I've an second board Z690M-ITX/ax, also insered a new other Intel i5-13600k and the same storage with an other power supply from Enermax. This board has the same (!) Problem with the intel cpu. Both cpu's are new out of the original box.
Thank you.

	I thing I found the reason. The board's (brandnew from dealer) needs a bios update :-(. How to hell should I do this without HDMI output?! The board needs a CPU for the bios menu.

	Unfortunately this happens. ASRock can't flash boards that have already been sold to retail outlets. The retail outlet is responsible for updating BIOSes for their inventory. You could reach out to your retailer and see if they have some kind of policy for this. Otherwise you will need to buy/borrow a compatible CPU so you can update your BIOS. Perhaps from a store that will allow you to return it afterwards. Alternatively you could take the system in to a service center and pay them to flash the BIOS for you and get it all working together. Before motherboard manufacturers were forced to switch to the larger, soldered BIOS ROMs (they were socketed before), ASRock would have been able to send you a new BIOS ROM that is preflashed with the correct BIOS version. Sadly those socketed ROMs are no longer produced and were never available in the capacities needed for current generation BIOS files. Try with the retailer first, hopefully they will be able to sort out the issue for you.
