What are the best android app to let your tablet act as a second monitor?

I’ve tried app such as Spashtop and iDisplay without any good results really.
Obviously a good connection is necessary but I still get lag.

If it’s available for Android, go with Duet. I’ve had great experiences with it for macs.

If it’s not for Android, sorry man. I strike it from the record!

I assume you’ve tried Air Display from Avatron Software? I’ve got it working with my Mac & Galaxy Tab A, but haven’t used it much (haven’t been on the road with it yet). It is rather slow, but I imagine most WiFi solutions would be. I’ve not tried Splashtop, iDisplay or Duet yet so I can’t compare them.
