I’m using this app to get a dual display using an Ipad with my laptop and it works great.
In case somebody is looking for a similar solution…it doesn’t use wifi like others so for people working on the go is perfect as well.
I have seen that. I’ll have to check it out.
the app is only $9…I do need to buy a clip to hold the iPad.
I ran that a year or two ago and there was something that went screwy with 3dsmax but cant recall it off hand. So if max starts acting weird try uninstalling that app off of your desktop before other troubleshooting. If I remember what the heck it did to mess up max Ill chime back in here but it was enough that Ive not used it since which sucks as it was pretty cool otherwise 
I haven’t had any problems so far
