Frederik Long. In reply to WilumMafoe's post on October 1, Your apparent lack of interest in solving your problem more than three weeks of silence! If you look hard enough using a search engine then you should find a ready-made solution.
In reply to Frederik Long's post on October 1, Don't let my lack of responding ruin your day, Fred. After all, this is just a virtual world. I did respond and the solution you suggested is not what I'm looking for. I don't think writing code should be necessary to perform a simple task such as adjusting brightness. Click the Action tab. It's at the top of the Device Manager window.
Click Properties. This option is at the bottom of the Action drop-down menu. Doing so opens your monitor's properties. Click the Driver tab. It's at the top of the Properties window. Click Uninstall. It's near the bottom-left corner of the window. Wait for the driver to uninstall. This only take a moment. Once the driver has uninstalled, your Device Manager list will refresh, and you will notice that the "Monitor" category is gone.
Click the "Scan for hardware changes" button. It's the square, computer monitor-shaped button at the top of the Device Manager window. Doing so will reinstall and update the driver that you just removed. Verify that your monitor appears back on the list. Once the Device Manager scans for changes, it will automatically reinstall the basic Microsoft driver for your monitor. This should re-enable the brightness slider.
Reboot your computer. This may not be necessary for your changes to take effect, but can't hurt and may save you a step later. Try to adjust your brightness.
Once your computer reboots, click the Power Options button in the System Tray to find your restored brightness options. If you still don't have a brightness slider, your graphics adapter may not support it. You can try to update the drivers for your graphics adapter , or you can try to upgrade to Windows You can find it in "control panel. Yes No. Not Helpful 39 Helpful I was reducing the brightness on the monitor and it went all black. How do I fix it? First, make sure you didn't turn the brightness all the way down.
If that's not the issue, reboot your PC or try to update your graphics driver. Not Helpful 25 Helpful Include your email address to get a message when this question is answered.
