I suggest creating a new Crop/Pad filter for any specific game, so you will be able to switch between them when needed. You can use it with MOBAs like Dota 2 and League of Legends, FPS such as Battlefield and Call of Duty, and RTS games like Age of Empires and Starcraft.
This guide explains how to show the minimap from any game on your second monitor. You can rename Crop/Pad, which is useful if you are creating minimap filters for several games. You want to crop all the in-game areas around the minimap. It is a fast moving unit that can be produced from the Factory without any other requirements, and can be built 2 at a time with an optional attached reactor.
I suggest starting with 800-1000 and then slowly find out the perfect fit for your display. The Hellion is a new unit in starcraft 2 which is designed to function similar to the firebat in starcraft 1 (even though it does look a lot like the vulture from starcraft 1). Impressive, considering one is a full modernised remake of the original StarCraft and its expansion. Every one of these campaigns can be played start to finish, fully intact and without a scratch on your wallet. If you are playing on a Full HD monitor, these numbers are lower than 1920x1080. StarCraft 2's first episode - Wings Of Liberty - has full mod support, and Blizzard made it free back in 2017. The correct values depend both on the resolution of your gaming monitor and the position of the minimap in a specific game. Now you must crop the space around the minimap, and you can do this by indicating the pixel values for Left, Top, Right, and Bottom.
