After a bit more research, it seems like: if we used the lowest latency components, then 90+% of the latency will actually come from the display itself. Would you agree?
CRTs don't seem to have this problem, so should we be able to demonstrate <5ms of latency from hand to display using a CRT? It is unfortunate that so much latency was introduced in the obsoletion of CRTs!

Finding VA and IPS displays that run at 250hz and look good enough to be worth it are still hard to find.

And i was talking about input devices as whole.

I can clarify - all important latency came from display (if you exclude network latencies in some cases). But not display itself only but display subsystem.

>CRTs don't seem to have this problem,
Of course they have some latency. It usually is less than LCD on equal rate but non zero in any case.

>so should we be able to demonstrate <5ms of latency from hand to display using a CRT?
No (except allowing tearing in some cases).

P.S. Display latencies are definitely off topic for this thread, IMHO.
