Issues with Apple Thunderbolt Cinema Display on Z77X-UP5TH

[edwardo]

Hello,

I have a post installation Graphics issue with my Gigabyte Z77X-UP5TH (Thunderbolt onboard Chipset DSL3510L) firmware F12 (latest available)

The Apple Cinema Display shows repeats the screen several times, see attached photo of desktop.

I am using the latest Clover version 4289, with default config.plist from successful Unibeast 8.1 High Sierra installation.

When I remote into the machine with Apple Screen Share the image is perfect which suggests the issue is a hardware and not a software one.

Can anyone suggest a solution ? I would really appreciate it, thanks in advance for your time
