Hello: I am an older person with a 4k monitor. I need to use Windows 10 Magnifier for text that is too small to read or work with. I've already set my desktop resolution to magnify text 350%. That works for most software, but not all. I turned on Magnifier, but the magnified screen is completely black. Does anyone have a suggestion as to how I can adjust Windows so I have a clear screen under the Magnifier? I also have transparency turned on. Note, I joined recently so find my hello in the general discussion.
