OK, here I go again…
We are again having a discussion about how a feature that is not yet implemented in the sim is not working. Controlling pop out gauges on a separate display would require the implementation of multi-monitor support. A feature that MS/A has told us is coming but not yet supported.
While I agree the use of touch tablets would be really nice and I wish it worked, I have three android devices and a MS surface all ready to go, we have to just be patient. It will come.
