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.

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.
Point being, outside competitive games, I do not expect monitor hardware to be anywhere near the bottleneck for latency and response times.
