I Started a game with my kids Saterday (8,9,10,13) and they where saying I was drawing the map to slowly. This got me thinking of using roll20 to do the mab but we only have 1 small net book that I can bring into the living room. Then I rembered that I just got the Chromecast added to the TV. I played with it a little last night and you know what it works. You open the Gm screen as one tab and then you open a players screen or log in a second time but tell it to swtich to player view and then you tell chrome to send it to the Chromecast. Yes I will have to move the playes and switch to the player tab when I have to move the whole map since it it to large to see all at once but they can all see the Tv easly. This weekends game is when I am going to do it for the first time.
