All we need is an easy explanation of the problem, so here it is.
I would like to know if there is any standard or feature which allows desktop LCD monitors backlight control setting in software. I would like to know what I should be searching for. This is a pretty common feature of laptop computers, but I’m not able to find an equivilant for desktop/standalone monitors.
I have tried a few ‘sofware only’ solutions which effectively just control the brightness sent to the monitor – not the backlight of the monitor itself.
Of course I can change the setting easily by using the OSD of any monitor but this is not always convienient to change.
How to solve :
I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
The standard is DDC/CI and seems to be widely supported – it may need to be enabled from the monitors OSD (mine was disabled).
softMCCS from ddc-ci.com allows lots of control but it’s too low level technical for regular use.
Just to control brightness and contrast I’m using http://clickmonitorddc.bplaced.net (Windows).
ClickMonitorDDC seems to be down/no longer supported.
DDC/CI is a quite simple standard that already exists for a long time. However, monitors vary wildly in support and correctness weirdly enough. Microsoft also never bothered to have a ‘designed for Windows’ certificate or something which could have easily fixed the lazy support from manufacturers. One compact utility to try is https://www.microsoft.com/en-us/p/ws-monitor-controls/9mzx4mf014qk
Let’s you adjust brightness, contrast, colour and volume (all depending on monitor willingness to cooporate).
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
