AHK

Auto Hot Key (AHK) is small but powerful automation scripting language for windows.

In this Quick video I demonstrate how to install AHK and create your first script. All AHK commands can be found here if you are creating your own scripts: https://www.autohotkey.com/docs/AutoHotkey.htm

This scripts helps change DPI and Resolution of your monitor in windows 10. Some games need the DPI to be 100% or the gun will not work

lets talk through this script

Line 6: this is the hotkey to change enable the change (currently set to ! (ALT) + # (WinKey) + PageDown

Line 7: "ACR0408#ASNmpEVZnard_00_07DD_A1^1977EFB0FCDDA00B4A190B2C0A4C2256" is the name of my monitor this will need to be changed to your monitor name This can be found here

The DPIValue are the following 0 = 100%, 1 = 125%, 2= 150%, 3= 175% and 4= 200%

Line 8: this is for your Resalution settings

Line 11 to 14 are the same as above You need to change these settings also

Line 18 to 25: you don't need to change anything here. This just changes the settings and applies them. If this isn't here the regedit would not change anything

NOTE if you have 2 or more monitors you will need to choose one under HKEY_CURRENT_USER\Control Panel\Desktop\PerMonitorSettings\ and do a trail and error. I don't know how windows makes this reg folder for the display name.

Do don't have to use a key bind to call the script you can put in before your load your rom. You need to change the Reg file before calling the change res.
