walkman7 Posted September 24, 2023 Share Posted September 24, 2023 (edited) Hello everyone, I do not know what I can todo else to get video working video output on subject machine. The strange thing is that I see fully working GPU acceleraion when connected via VNC but in this case none of two DP ports provide video signal. What are your thoughts on what could be wrong here? What I tried todo: 1. Busid bruteforce for all connectors, no luck 2. `igfxonln=1` – nope 3. Changing monitors, no way But if I boot with `-igfxvesa` (i.e. disabled GPU acceleration) my display is connected Spoiler IOReg Mac mini - Dell.zip Edited October 1, 2023 by walkman7 Link to comment https://www.insanelymac.com/forum/topic/357711-dell-optiplex-5090-mff-i5-10500t-uhd630-no-video-out-black-screen/ Share on other sites More sharing options...
