I'am playing face2face with my friends since 4 weeks. My Setup is Laptop and two cheap Displays (1920 * 1080 - around 100,- EUR) and a HDMI-Splitter (doubling an HDMI Signal - only necessary if your Laptop has only one HDMI Output). I've created a second Roll20 Account and gave this "Player"-Account the additional control of the 4 Player-Chars. On the 2 Displays i show the Players what their Chars see on the Map. One Display für the Players, one for me to control what they see. So the Players always see what ALL Player-Chars see. Thats not optimal
if the Party splits - but we are professionals, so the player forgets
immediately what their Characters could not see :-) The new Dynamic Lighting is really buggy, so sometimes my players see thru blocked doors, etc. I'am using Chrome for my Master-Roll20 DMing, and Firefox for the Player-Screen. So I havent problems with to Accounts in one Browser. The Players playing with their Tablets - not very comfotable due to the loosy support of Tablets by Roll20.So often i have to put their chars were they want to go. But they could see it on the Player-Display and give me advice. We like the Char-Sheets and let Roll20 Doing the whole calculation for Attack/Damage etc. We like also the Mapping and the dynamic Lighting. We dont like that theres no Tablet Support for moving chars on the Map.
