It was called "Continuum" and was introduced with Windows 10 Mobile. Worked pretty smoothly but it couldn't run win32 application only the new modern UWP apps. Introduced 6 Oct 2015 alongside the Nokia Lumia 950/950 XL. Discontinued when Windows 10 Mobile reached end of support in Dec 2019.

I remember when MS was pushing UWP apps hard. So many things needlessly handicapped. I'm glad they seem to have kinda given up on that now.

UWP was limited because it was the subset that could run on PC, Xbox, Phone, and HoloLens. Being able to make one responsive app and deploy it across that ecosystem was pretty awesome.
But when you kill the non-PC platforms, you're just left with a reduced capability version of windows apps
