In-Person Game with Dynamic Lighting - Character Perspectives Help

Hello! I'm going to be running an in-person game with 4 players at a table using a tv screen for the map. My current plan is to run the game from one computer and have the game displayed via a different computer with control of all the player characters. I'm trying to figure out if there's a way that I can differentiate the vision perspectives of each character on the tv. I know ctr-L will show me a token's vision as the DM, but I would love to not have to switch between the computers whenever a different character is acting. I tried setting a tinted darkvision or a colored light from each character, but it doesn't help differentiate perspectives in daylight. Ideally, I could show character vision on the tv from the computer I'm dming from. Any suggestions are welcome, thanks in advance! *Edited for term clarity.*

You can use the Observer script, which will only show the view of the current PC token at the top of the Turn Tracker (or show vision from all PC tokens when an NPC is at the top of the Turn Tracker).  I strongly recommend not using colored vision, as it causes weird coloring wherever colors overlap. 

Wow, this is exactly what I was hoping for! Thank you so much!

**EDIT** Nevermind, I was overlooking a built-in feature!  Jarren said: You can use the Observer script, which will only show the view of the current PC token at the top of the Turn Tracker (or show vision from all PC tokens when an NPC is at the top of the Turn Tracker).  I strongly recommend not using colored vision, as it causes weird coloring wherever colors overlap.  One issue I'm coming across with this is if there's multiple tokens associated with a single character sheet (a bunch of goblins), it shows all the locations of that character sheet's token across the map. Do you know if there's a way to keep this from happening? All the NPCs don't have vision on, but if I turn it on, the problem becomes worse and shows every goblin's vision.

HI Noah, Remember to use a dummy account (or player account) to see how things look from the player point of view.  They shouldn't be seeing all of the NPC tags unless they have control over that character and it's tokens.  My guess is you are viewing that from your GM account?
