For lowest latency you may also need a CRT. Thin screens are getting better but every stage of the pipeline can introduce more lag than the original.

That's true. I have a trove of CRTs for playing Melee :)

But for the average N64 classic, a commercial HDTV with an upscaler works fine. A high refresh rate monitor also works great (even for something as precise as Melee.)
