i recently grabbed a PC from 2007, installed XP on it and a CRT monitor.
never have i felt a computer react so quickly. CRTs have much less lag than LCDs.

Isn't this just what high refresh screens are? They sell like 165Hz screens with G-Sync or Freesync.

Even lower latency than a 165Hz screen with a full framebuffer is a 165Hz screen without a full framebuffer.

There are lots of "gaming" monitors that advertise on high refresh rates and low latency. We're talking like 4–5ms input latency and pixel response times <2ms.
Point being, outside competitive games, I do not expect monitor hardware to be anywhere near the bottleneck for latency and response times.
You probably can't avoid the time it takes for the pixel to physically change (~1 frame) but you can avoid all intermediate framebuffers by careful timing synchronization. E.g. when scaling, don't buffer a frame at a time, just a line.
