tfouto No subpixel font smoothing in Windows 10. It's greyscale anti-aliasing.
You know, it's funny.. my work managed laptop is a T480 on windows 10 build 1803. Funny thing is, I also have the usb dock it came with, so usb-c to the dock, displayport output from the dock to an old HP displayport to DVI active adapter to my old CCFL monitor, and the backlight looks more stable than on my regular PC which is Win 7, mini-displayport out to active vga adapter to same monitor. The image is fine and I'm confident you all can use it, but there's this subtle background shimmer that isn't there with the T480 setup as-is. One of these days I should look for a mini-displayport to displayport adapter, so I can plug in the same HP to DVI and see how it looks on the Win 7 machine.
I was just now playing with a laptop from 2005, was a good one back then. Amazing how fast it is with a SSD drive in it, even after all these years. Anyway the hardware isn't that healthy anymore unfortunately. The screen isn't that good today. There's this shimmer or fuzz that's hard to quantify, almost a snowy moire effect. I think it might actually be the backlight beginning to fail because in one corner of the screen there's a crack (not on the glass, but behind it) from someone having dropped or crushed it. CCFLs don't last forever unfortunately.
I'm going to slap OpenBSD on the antique laptop tomorrow probably and see how it compares to XP and Linux which I've already viewed on it.
