https://monitorsanywhere.com/ has moved to an Android device for its video walls.

Here is a link to a review (sorry about its advertising) https://androidpctv.com/review-x96-max/#PRODUCT_DETAILS

Windows only software for extending desktop to this Android device. https://spacedesk.net/

Android sits on top of a Linux base OS. Its directories are organized differently than other Linux distros. Here is the root of its file system:

You can replace the provided OS with Debian Buster installed on a MicroSD card. https://docs.armbian.com/

Wow! one x96 MAX supporting 3 independent workstations. The display connected directly to the x96 has something odd going on with its colors. If I do a screenshot, the colors are normal so the problem has to be with the x96 video driver. To test that I configured an HP T150 USB 2.0 zeroclient which has a different driver. That works perfectly. So then I added a second HP T150 and made both of them independent seats. That works fine for office type applications, but the x96 would not be able to support three seats displaying full screen video on each seat display at 1920 x 1080.

The following drivers are missing or inadequate in Ambian Debian Buster when used for the x96 MAX: 1) video driver for the SoC: Amlogic S905X2 Quad Core Cortex A-53 (64bit) / GPU Mali-G31 MP2 / 4x ARM-A53 @ 1.8GHz; 2) network driver – I connected a Plugable USB 3.0 hub with 3 ports and gigabit network adapter which was supported; 3) the led clock driver. There may be additional drivers missing if installed internally instead of booting from microSD image.
