Win10 Wallpaper= 85% JPEG. Doh !
Clearly I'm the only dufus on the planet that didn't realise Win10 was degrading my shots when used as wallpaper.
I've been using 3rd party software for years but thought I'ld try for a simpler life on my Win10 machine.
Looked at a shot yesterday and thought it looked soft, did some checking and guess what ?
A year and a half of sub-par displays.
On the off chance there IS someone else, here's the story and the fix
Volunteer, what could possibly go wrong ?
