Resolution of Automation-Systems

there's a lot to read about automation. it's always about price, features and so on... i'm interested in audioquality.

so let's try to collect the facts about resolution (time and dynamic), sync, protocoll, Interfacing, VCAs,...

(my english is just basic - sorry about that)

MIDI

"The bandwidth limitations of the serial Musical
Instrument Digital Interface (MIDI) protocol used by
many control surfaces creates a tradeoff between
responsiveness and the number of controls. With 31.25
Kbit/s MIDI, for example, a maximum of 35 controls
can be controlled in a 33 ms video frame interval
(assuming three byte MIDI commands)."

"In addition to bandwidth limitations, many of the MIDI
protocols have insufficient resolution in their data types,
for example 128 discrete values for a knob, compared
with over a thousand discrete values that might be
necessary for accurately choosing an EQ frequency
value."

EuCon

"EuCon control surfaces use 100 Mbit/s Ethernet. This
provides three orders of magnitude more bandwidth
than MIDI and will scale up as Ethernet speeds increase."

"The primitive’s 32-bit integer and floating point values
provide much higher resolution than the seven bit values
found in some MIDI protocols."

DAW with Mouse

working with a mouse and DAW - as far as i know - the resolution of fader-values are depending on the number of pixels on the monitor. this would mean that a faderride on a big screen "sounds better" than on a small one, cause more points/values are represented. or did I get this wrong?
