[Solved] Acer Aspire TC-780: Screen shows no signal after verbose on Monterey or Ventura

[Lost-Entrepreneur439]

I have an Acer Aspire TC-780, I've tried to hackintosh it on both Monterey and Ventura, however after the verbose on both of them, my screen just goes to no signal. On Monterey, I tried using the "-igfxvesa" bootarg to force it to use VESA mode, which did allow the system to boot and for me to install macOS, but obviously, I don't want to use macOS with no GPU accel. Anyone know how I can fix this? Preferably I want to fix it on Monterey since that is what's currently installed on the HDD. My EFI is attached.

Is there an option in the BIOS to set DVMT to 64MB?

if not, then you could patch it by adding to the config file

framebuffer-fbmem = 00009000  (data)

framebuffer-stolenmem = 00003001 (data)

That and experiment with other desktop KBL framebuffers as provided in the WEG user manual.

 

But, more importably, what kind of video output port are you using? KBL FB 0x59120000 defines 3 DP ports:

TOTAL STOLEN: 39 MB, TOTAL CURSOR: 1 MB (1572864 bytes), MAX STOLEN: 115 MB, MAX OVERALL: 116 MB (122171392 bytes)
Model name: Intel HD Graphics KBL CRB
