Woah, this is amazing!
I was looking for a way to find the GPU load a while ago and I think I finally found it. =)
I'm wondering if there is a similar API for AMD?

Hey could you please explain me how you managed to CHANGE the Digital vibrance for a specified Monitor?

I don't have your skills in AHK or something... it's like magic for me what you've done!

For Example:

I wan't DV @ 75 instead of stock 50 on Monitor 1

and the other Monitor stays @stock 50 how to hell do i manage that?

Code: Select all

DllCall(NvAPI._SetDVCLevelEx, "Ptr", hNvDisplay, "UInt", outputId, "Ptr", &pDVCInfo, "CDECL")
SetDVCLevelEx() accepts a hNvDisplay handle which could be determined within SetDVCLevelEx() if either the monitor name or the index to use with NvAPI.EnumNvidiaDisplayHandle() would be passed to the function.
To get the handle associated with the monitor name NvAPI_GetAssociatedNvidiaDisplayHandle() might be useful.

Cool, but does it deal with SLi configurations? The classic example doesn't, atleast.

Awesome script though!

Its because I can not test it with SLI

(p.s. Temperature text failure: save your script as UTF-8 | or use Chr(176) for °)

Well, to be honest.... i don't get how i set the DVC level with a hotkey, can i add you in steam if you want?

I't really heavy to understand for me.... that looks like higher programming skills for me...

Here is an example how to change DVC via Hotkey

Code: Select all

; GLOBAL SETTINGS ===============================================================================================================

;#Warn
#NoEnv
#SingleInstance Force
SetBatchLines -1
#Include Class_NvAPI.ahk

; SCRIPT ========================================================================================================================

OnExit, EOF
NVIDIA := new NvAPI()

def := NVIDIA.GetDVCInfoEx(0).defaultLevel


; Win + Numpad 4 (or Numpad Left)      ==> Decrease Digital Vibrance by 1
#Numpad4::     NVIDIA.SetDVCLevelEx((DV := NVIDIA.GetDVCInfoEx(0).currentLevel - 1) > 100 ? 100 : DV < 0 ? 0 : DV, 0)
#NumpadLeft::  NVIDIA.SetDVCLevelEx((DV := NVIDIA.GetDVCInfoEx(0).currentLevel - 1) > 100 ? 100 : DV < 0 ? 0 : DV, 0)


; Win + Numpad 5 (or Numpad Clear)     ==> Set Digital Vibrance to Default (50)
#Numpad5::     NVIDIA.SetDVCLevelEx(def, 0)
#NumpadClear:: NVIDIA.SetDVCLevelEx(def, 0)


; Win + Numpad 6 (or Numpad Right)     ==> Increase Digital Vibrance by 1
#Numpad6::     NVIDIA.SetDVCLevelEx((DV := NVIDIA.GetDVCInfoEx(0).currentLevel + 1) > 100 ? 100 : DV < 0 ? 0 : DV, 0)
#NumpadRight:: NVIDIA.SetDVCLevelEx((DV := NVIDIA.GetDVCInfoEx(0).currentLevel + 1) > 100 ? 100 : DV < 0 ? 0 : DV, 0)


; Win + Numpad 8 (or Numpad UpArrow)   ==> Set Digital Vibrance to 80
#Numpad8::     NVIDIA.SetDVCLevelEx(80, 0)
#NumpadUp::    NVIDIA.SetDVCLevelEx(80, 0)


; EXIT ==========================================================================================================================

GuiClose:
EOF:
NVIDIA.SetDVCLevelEx(def, 0)
NVIDIA.OnExit()
ExitApp

This script is great! I used a small bit of it in a program I made called sourceGL (and credited you in the credits text file :) ). I'm going to make a thread for it

@jNizM I'm trying to add some NvAPI functions like GPU_SetCoolerLevels to your AHK Nvidia library, but I'm having trouble with the DllCall's. Would you add me on Steam and take a look at my code? I'll PM you my Steam profile. Thanks

Hi, Is it possible to control brightness, contrast, saturation?
