Hello All, I'm new to this wonderful VA but just thought I'd share something. If anyone (like me) uses a cloud PC to get better FPS/General experience, you may have never been able to get an external MCDU on a tablet, as the tablet would not be able to link in with the cloud PC's network. 

I found an alternative method detailed below (based on my own set up but tweak for your own purpose)

I use my main PC for the running of the sim, I have a second monitor to display the PFD's etc.

Using google chrome remote, I now display my MCDU onto my second monitor. Now having downloaded google chrome desktop on my tablet is synced the  PC, I now have an external, functional MCDU on my tablet which is responsive and has zero impact on FPS.

The only drawback is that I now have an MCDU displayed on my second monitor but I can adjust the size of it so that it is only that of which is displayed on my tablet not my PFD's etc.

I use the Latin VFR A319/A320 with the horizon mod.

Just sharing some ideas for more immersion, happy flying!
