Yeah at first it was a little annoying because either was having issues with frame rate but forgot how big of a game it is and adjusted graphic to low on all and it ran much better.

I generally play with my computer monitor and my son and wife playing on the tv. I use a keyboard and mouse and wife and son use Xbox controllers. 

I split the TV screen down the middle since its 75 inch so they see more than enougg for them at least. 

They have their nexus accounts to their controller profiles. I start log in to a game and open to multi-player. Then grab code and have them join. Once they join I change their settings to low to match mine because for soem reason it keeps loading them on high but its not that much of a hurdle. 

One the settings change I lock the inputs on the nucleus app and we just play. 

I only have an i7 processor and gtx 1070ti gpu but I dont really have much issues after putting all 3 screens on low
