AMD Radeon HD 6450, Windows 10, Hannspree HF205DPB. My monitor dims whenever the screen content is mostly black and rebrightens when I change the content to include more white space. How do I stop this?
I found a review of my (used) Hannspree monitor that explained that this is a monitor feature called X-Contrast. Turned it off, no more problem.
Yeah, this will be an energy-saving feature of your monitor rather than anything to do with the graphics card. Manual or manufacturer's website should be able to guide you through turning it off, although it's usually fairly obvious in the monitor settings once you know what you're looking for
