Issues with disabling CSM or enabling secure boot on an ASRock motherboard can prevent the monitor from showing.
I attempted to turn off CSM on my ASRock board to enable Secure Boot, but now my monitor won’t power up at all. I believe the problem stems from switching to full UEFI mode, which may interfere with display output via BIOS. After rebooting, the screen stays black and unresponsive. I haven’t tested DisplayPort or integrated graphics yet, and I’m unsure if those would resolve the issue. Others have faced similar challenges—have you tried any adjustments or checked for firmware updates? Let me know how to proceed!

Which GPU are you using? Yes, older models such as the Radeon HD7000 Series don’t support UEFI by default. That means the screen won’t appear until the operating system loads and its display driver activates.
