Running 2 separate instances?

Hi, I've got kind of a weird usage question. I'm starting a game group & was planning on using Roll20 to allow it be done online. & I put a lot of time into creating the dungeon graphics in Roll20.  But now all the players are meeting in person.  So I'm trying to figure out how I can still use Roll20 (& all my great work) without it becoming too awkward or cumbersome. My idea was to have a computer monitor in front of my DM screen to show the players the Roll20 UI & allow them to see what the party sees.  But it might be a bit awkward to have 1 computer & user account control all the party members, especially for physical interface of having only1 mouse & keyboard between all the players. Can 2 instances of Roll20 be run effectively on the same computer, using the same user account?  I thought I could connect the player display monitor to my laptop.  Then run 1 Roll20 instance on my account in GM mode on my laptop screen, & then run a 2nd instance of my account in player mode & put it on the 2nd monitor.  This way I wouldn't burden the players with trying to control the player instance. One problem I see though is that if the player instance is on the 2nd monitor, then I won't be able to see it myself to control it. Any suggestions on how to work all this out? Thanks in advance

I have an old computer and I have no problems running two instances of the game at once. I always use separate browsers firefox, and chrome, but I am pretty sure you can use the same browser with two logins. As far as not seeing what the players see, that is no different than when you are playing online. I would just shift ping to get it centered, you will be moving the tokens for the players I assume, so you know where they will be.  if you need to adjust the zoom, you can always peek over to their screen. It should work out fine. Happy gaming.

Personally, I have two accounts, one for my GM screen and one for what the players would see. That way you can utilize fog of war.

I do this all of the time.  I'm running a campaign for a small group that required me running a DMPC alongside them.  I'm running two browser instances (helps that I have two monitors too) on the same computer, logged into the same account, with one as GM and one as a player.  Works pretty good so far.
