Values may differ system-to-system, so preferable range for brightness is 0 - 128 where 128 is the default brightness.įYI windows already has a monitor blue shade/color shift built in. This sets the brightness value, that's between 0-255. If SetDeviceGammaRamp(hdc, ref(GammaArray)): print('Values set successfully!') Print('New Current Gamma Ramp Values are:') GammaArray = changeGammaValues(GammaArray, brightness) If GetDeviceGammaRamp(hdc, ref(GammaArray)): LpRamp = lpRamp = lpRamp = iValueīrightness = 100 # can be aby value in 0-255 (as per my system) :param brightness: Value of brightness between 0-255 To reset the gamma values to default, call this method with 'Brightness' as 128 Modifies the Gamma Values array according to specified 'Brightness' value import ctypesĭisplays the GammaArray of 256 values of R,G,B individuallyĭef changeGammaValues(lpRamp, brightness):

To call these functions through Python, we can use ctypes module.īelow is the sample code that can set brightness of in Windows 10 via Python. We can use GetDeviceGammaRamp and SetDeviceGammaRamp from the gdi32.dll library in Windows OS to set the brightness level. This is a thread which actually asked this, but I didn't get my answer from here, and newbies are restricted from commenting, so I didn't have any choice than to post this question here.

#BRIGHTNESS CONTROL WINDOWS 10 HOW TO#

Maybe GammaRamp from the Gdi32 API can be used, but I don't know how to begin. I don't want the source code, I just want the way out for that.

If it can do it on at a software level, then I know its possible programmatically.Ĭan anyone tell is this possible what I'm thinking, and if yes, how can I achieve this?

I got something called gdi32.dll which deals with the outputs to screens, but I cannot find a way out as everything on the Internet is alongside C++.Īlso, I cannot even provide my try code, as I'm not that much familiar to C type coding in Python.Īlso, the thing I want to do, Intel Graphics Command Center already does it on my desktop. I primarily want to modify the output going to the physical monitor, that is to modify the Gamma values to get appropriate brightness and Yellow tincture.

#BRIGHTNESS CONTROL WINDOWS 10 INSTALL#

I'm not that much familiar with VC+ and I cannot even afford to install it on my system as it is too much storage and resource intensive. I'm working on Python with ctypes module. So my main problem is, How can I ajust the brightness of all Windows PC, including Laptops, Desktops n all others. I searched a lot and lot, which included Microsoft Developer Network, where documentation included the Win32 API where brightness feature was present, but it didn't work for me, as I had a Desktop PC. I made use of Qt5 for making a translucent app window which works good, but doesn't meet the requirement because the things displayed at kernel level are not masked like the cursor, taskbar, start menu, action center, and lots of other.

#BRIGHTNESS CONTROL WINDOWS 10 PORTABLE#

The main problem is for Windows systems, where the brightness feature is only available for portable screens such as for a Laptop. I'm making this app cross platform, so I've already found a solution for Linux Systems, where I've been making use of xrandr utility to adjust the brightness and gamma at the software level, and my app works flawlessly. I'm making a Night Light Application, which has two options-Īpply a Blue light filter mask over the screen. It might be possible for a similar question to be already present on the site, but I have searched a lot and didn't find any relevant solution, so I'm posting it here.
