Help with setup (Hybrid Online and live tabletop)

Heya guys! so i have a specific situation here.    I game with people that are here at the table but i also have friends that skype in.    I have 4 monitors that i use to broadcast with (yes i know its bit excessive but i need them).  i'm going to mainly concentrate on 2 screens here.   So the GM (Me) is using screen 1,  the players at the table are using screen 2.  but the players online are using their screens (which is fine but i'm more concerned about the people around the table here). SO.....naturally...i cant have the players looking at my screen 1, so i need to try to have another instance of Roll20 on another screen.  which i can do but... i cant have two DIFFERENT usernames signed in on the same PC.  So the players at the table will be able to see the player instance of Roll20 and i'll have my own instance (signed in of course) of GM Roll20 screen.  is there a trick that i can do this?? or what can i do to fix this??  (I really hope you understand what i'm trying to do here, if not just say, and i can try and elaborate on the situation) Thank you very much! Tim

Use a different browser to sign in the second account. Chrome incognito also works for having two accounts signed in at the same time.

TOTALLY WORKED!!!!! Thank you!!!

Also on Chrime you can set up different users and they have their own cookies/extensions/etc.  Workd like incognito but you can save your login and such. 

On the browser that is being used as the players screen, At the top of the right-hand status panel, select "Settings" (the little cog wheel) and then scroll to the bottom of the right hand panel , there is a button to "Login as player".  only that browser instance is affected, not the browser ;logged in as GM.  I did this last saturday. Works great!  Also you want to select the icon with three little horizontal lines near the top right of the map display (near the top of the right side of the map area next to the vertical scroll bar) This will minimize the status panel, then press F11 to make the browser go full screen on table top display. Word of caution, it is best to orient the table top LED screen so it's right side up to you the GM, other wise, trying to pan the map that's displayed on it can be difficult if your mouse movements are either at right angles or upside down in relation to that screen.   Korg sends
