Mark,
Do you have an option for in the NVIDIA Control Panel for “video sharpening” like the posters above you mention?
See this link for more details: https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/283996/blurry-text-and-icons-on-apps/
In the meanwhile you can use the web app, charts.navigraph.com.
Kind regards,
Stephen
