I suspect it is because the Lenovo isn't supporting dual DisplayPort channels, but that's just a guess. I have tried everything I can think of to get TWO Thunderbolt Displays to work simultaneously, but with no success. I suspect this is a limitation of this particular Lenovo computer's implementation of Thunderbolt 3, as my previous Lenovo, with Thunderbolt 2, did recognize these components.
I haven't been able to get Windows to recognize the camera, speakers or docking station components of the Apple Display. Occasionally, I get screen flickering, particularly when I do a hot-swap on the Thunderbolt port. I've found using 'None' to incur the fewest problems.ģ.) BIOS Support for Thunderbolt must be enabled in the Thunderbolt settings. This allows the display to be seen by the computer without the need for user authentication of the device. This isn't specific to the Apple Display, but appears to be necessary to get the Thunderbolt protocol to work properly.Ģ.) Security must be set to either 'Display and USB' or 'None' under the Thunderbolt part of the BIOS. The Lenovo's BIOS needs some settings changed in order to allow the Apple Thunderbolt Display to work.ġ.) Data Execution Protection in the Virtualization section of the BIOS must be turned off. However, what I've discovered might apply to you. My setup is a Lenovo with Thunderbolt 3, not TB4.
