Here are my pictures to show you what's happening. I'm playing a bunch of games and I see weird Magenta/Cyan outlines around things in the corner of my screen. I don't know why this is happening. It shows up most on Microsoft Flight Simulator 2020 and High on Life. Here is what I've tried so far: I updated all my BIOS and drivers by doing a clean install, but swapping out my graphics card for an old one didn't fix it because the shading problem stayed the same. I changed the graphics settings in both games including anti-aliasing and went through every single setting from low to high. I also tried different screen resolutions without any success. I double checked my monitor settings. I looked at Nvidia Control Panel for all settings, even resetting everything back to default. They've taken away the option for 3D Stereo since 2017. I haven't overclocked anything and it's just running on stock settings. Is this by design? Any help in fixing this would be awesome.

Update your post with the full system details. Tell me what kind of power supply you have, its brand, model, wattage, age, and if it looks good or bad. Also list your hard drives: make, model, how much space they hold, and how full are they right now? What monitors do you own? And what video cables are connected to the screen?

Many games use slow, low-quality graphics on the outside parts of your computer, which makes pictures look pretty bad.
