Adjust the brightness level.

  • Hello, before asking a question, I will explain the context, using OperaGX on a website which offers different options to play a video, when opening the video in full screen the brightness level of the PC increases, I would like to know how I can prevent this from happening.

  • Hello. You've said "using OperaGX...", so I suppose that the problem only occurs in that specific browser. Anyways, I have in mind two solutions:

    1. If the problem happens in other browsers, it may be due to your PC. I don't know about other OS, but in Windows 10 you can adjust the screen's brightness level activating the night light in the system's screen configuration.
    2. On the other hand, I suggest you to use Night Shift. This is an extension that I use and it's very useful. You are able to adjust the brightness of your screen by modifying the opacity. Also, it has a dark mode.

    Lastly, whether you have extensions in Opera GX, try to deactive them and verify the brightness issue.
    That's all, I hope your problem to be resolved.

  • No, the problem only appears in "opera Gx". Now I also understood that the problem not only affects different pages, the problem also affects the same browser by pressing "F11" without opened pages.

  • If the problem also appears by pressing F11 without opened pages, in that specific case; you can avoid it. Now, have you tried what I said? I mean, deactivate extensions and, also, whether you have GX control turned on; shut it off.
    Your problem may be occurring because of many factors, so I suggest you to install an extension to adjust the brightness again until the problem is gone.
