help: I have a fully working Hack with Big Sur 11.4 and OpenCore 0.6.9 with graphics acceleration working. I cannot get HDMI or Thunderbolt to display - monitor goes to idle sleep. My specs ar:

Intel i7-7700hq (Kaby Lake) Intel HD 630 Asus ROG Strix GL753 laptop. HDMI is via Intel HD, not dGPU (checked in Windows)

Tried all the options in Whatevergreen wiki, no luck.

Please help. Thanks
