I don't think that LCD buffer anything. I've experienced screen tearing which should not happen with buffering. Most applications implement some kind of vsync which introduces buffering and related delays indeed. Best option is to use adaptive sync and get rid of vsync. But support for this technology is surprisingly not mature, it works mostly in games.

Screen tearing happens when the software swaps buffers on the GPU while the GPU is in the middle of reading out a buffer to send to the monitor. That tearing has nothing at all to do with whatever buffering is or isn't happening in the display itself, because the discontinuity is actually present in the data stream sent to the display.
