Busting the Anti-AMD myths!!!
Ever try a different hdmi cable?Recently switched to a reference 6900XT from a 3070 for my main a few months back and the 6900XT has compatibility issues with my ASUS monitor, there is no signal over HDMI until I have the drivers installed. Originally this had me stumped and I thought the card was dead but I tested the card on my old DVI monitor which worked for me to install the drivers. So other than having to aquire a DP to VGA cable to access the BIOS and doing some mental gymnastics during graphics driver installs and missing the window welcome screen when the monitor auto switches from VGA to HDMI, the 6900XT has been rock solid. I have used AMD cards plenty in the past but this is the first time I've encountered such a finicky issue. All the recent graphics card I've used which happened to be Nvidia, GTX 1070, GTX 1080 Ti and RTX 3070 just worked with this monitor.
Yes, even dropped cash on a few DP to HDMI with no luck. My monitor is a VX24A. Done some quick googling around and I'm not the only one to encounter this.Ever try a different hdmi cable?
I think your mobo needs to be in full UEFI mode with legacy boot disabled and secure boot enabled to get AMD cards to display at boot.I have used AMD cards plenty in the past but this is the first time I've encountered such a finicky issue.
CSM disabled, secure boot enabled. No post with HDMI, or DP to HDMI. Just DP to VGA works, I would assume HDMI to VGA would work too but I don't have one on hand.I think your mobo needs to be in full UEFI mode with legacy boot disabled and secure boot enabled to get AMD cards to display at boot.
Which mobo chipset are you using? I don't have such issues with RX 6800 on Z790. However, with an older Z67 and RX 580, I did cuss a lot due to similar issues.CSM disabled, secure boot enabled.

Chipset is X570. I'm pretty sure it's not a chipset and GPU issue as someone else with a 6650XT and Z690 has the same issue with the same monitor. Also this doesn't seem to be isolated to the RX 6000 series, it goes back to the RX 5000 series as well. Issue mostly appears to crop up with an AMD card paired with an ASUS monitor but not always, other monitor brands can be affected too.Which mobo chipset are you using?

Thanks, I'll consider reflashing it if I ever upgrade my monitor and still can't see the post screen or enter the BIOS with HDMI or DP to see if that's the fix. Right now it post via VGA and I can see the post screen and enter the BIOS, when it loads windows it auto flips to HDMI, otherwise it's perfectly functional in windows and games just fine.Not able to access BIOS Screen. Doesn't show boot screens.

Seems you need to reflash the video BIOS of the card to fix the issue. Pretty extreme.
