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. You don't have to use a key bind to call the script you can put in before your load your rom and then run the 2nd part in your exit script NOTE You need RegWrite before calling the change res.

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.
