Info My Z590 Board POST with single beep but no video displayed (2021 HDCP)

[Robert_407]

Wanted to post this here for anyone that might run into same trouble as me. When attempting to setup z590 chipset (Asus Z590-I) I got the dreaded single beep post, with no video. It turns out I was using an older HDMI cable to connect this 2021 board to my 2020 LG monitor. After grabbing my 4K "High Speed" HDMI cable off of the TV and trying that, video suddenly came up! One can only assume it has to do with modern hardware requiring an 18GB cable and perhaps needing to support HDCP? Either way check your HDMI cables as part of your troubleshooting workflow before you reseat / unplug everything!

If you didn't mention the part about going for a concurrent cable(as opposed to older cables) I'd have looked into the CPU socket pins, then the BIOS version on the motherboard.

Regardless, thank you for the info!
