Brightness doesn't adjust on MD20641 #149

Open Gamingjojo909 opened 3 years ago

Gamingjojo909 commented 3 years ago

Hello, My Medion MD20641 doesn't change it's brightness after changing the slider. I also have another display (S24D330), and that works fine. I have tried other apps (ClickMonitorDDC and Monitorian), but they are either outdated, don't detect my S24D330 or just don't look as good as Twinkle Tray does. I know for a fact that my MD20641 has DDC/CI support because it worked on both Clickmonitorddc and monitorian.

@Gamingjojo909 Could you go to the Debug menu and let me know the full information for your MD20641? You can copy/paste it.

Hmm, everything looks OK. Any chance you can try using a different cable type (ex. DisplayPort) or different HDMI port on your PC?

I tried VGA, and it still doesn't work/:

Is the key supposed to be the same on both monitors?

xanderfrangos commented 3 years ago

The "key" should be different for each monitor. Are they showing up as the same for both your MD20641 and S24D330?

Nevermind, the last digit is different...
