MST Limitations
- If you enable MST on monitors, display audio does not work.
- If you reboot with multiple monitors connected, one monitor may display a black screen. As a workaround, unplug and plug in the monitor that is connected to ThinOS.
- Do not hot-plug the daisy-chained monitors as this can cause a black screen issue. You can hot plug the monitor that is connected to the ThinOS client.
- If you connect two or three monitors with MST and plug out the monitors, ThinOS stops responding for 15 s to 30 s. When ThinOS stops responding, do not plug in the monitors again. Wait for ThinOS to recover and then plug in the monitors.
