Display Port to HDMI troubleshooting: OptiPlex MFF 3090 i3-10105

[gatorback]

An OptiPlex MFF 3090 i3-10105 is configured with OC & Monterey as described (EdHawk2config.plist link):

Is there any reason Monterey will not boot on a OptiPlex MFF 3090 i3-10105?

The i5 3090 MFF seems to support Monterey: https://github.com/Aaron9466/dell-optiplex-3090mff-opencore lshw output of the 3090 MFF Intel(R) Core(TM) i3-10105T CPU @ 3.00GHz version is attached. Attempts to boot a Monterey USB installer were unsuccessful. UNRESOLVED RELATED POSTINGS...

Although 2k resolution via Displayport works fine, 4K resolution does not work as described:

Attempts to connect to HDMI monitors (4K monitor , 720p TV, 1080p monitor) fail: the Dell Logo is returned as expected. The OpenCore Picker displays correctly, however, once the SSD is selected the screen goes black and returns nothing.

I believe that this is not the first time this problem has been reported. Replies with any diagnostic questions or a remedy are appreciated. Thank you

Hi.

Two things:

1) 15.9MB and 9.9MB are too large for simple photos. Please reduce the size. Maybe use JPG.

2) No need to post links off-site. Simply upload your EFI folder as a ZIP archive and attach to your post.

@rathan: Thanks for the response.

Is your 3090 MFF outfitted with I3 CPU?

What version of OpenCore did you post? Does it support macOS Monterey?
