No, this only works in the positive direction (making pixels bigger so vision-impaired people can read text, for example).

What I need is this setup, but be able to go lower than 100%. So if I chose 50% for example, my 1366x768 LCD actually looks like a 2732x1536 desktop to Windows.

Win10 won't go lower than 100%.

Looks like there may be a way around it with a registry change:
