Black screen issue hdmi to dvi

I have i5 6600 skylake with intel hd 530 graphics and r7 350x graphics card (if i use this then there is no graphics acceleration but boots in recovery). Want to install Monterey. If i use igpu creating specific config.plist for it, adding framebuffers also i get black screen in recovery. If any one have solution plz tell me. I connected hdmi cable in pc and connected through dvi connector to monitor.

I think i need to patch cable but how can i do that which frame buffers i need to add in device properties

Plz anyone guide me if can to solve this problem.
