video gauges?

hey everyone. ive seen a couple of setups in cars with video screens with gauges/ monitoring programs on them. would this method be practical if it could be afforded? also, is it easy to set up and what companies offer such programs if available. it would still be cool even if really expensive

pioneer is the only one I have seen that offers a setup like that

mechanical gauges are always most accurate. Dont you ever wonder why a 10 million dollar fighter jet still use mechanical instead of electrical ;)
Unless you just want to look cool, I guess electrical is fine.

I beg to differ. many newer jets use entierly didgital gages. all comercial jets are lcd screens with it all digital, and alot of test equiment is digital. plus youve had digital spedos and tachs in cars for years, people just like the way the analog look. anyways the gages are the only non digital part eveyrhintg else is didgitaly controlled and read. (correct me if im wrong).
but thast just my :2cents:
-C

A bit of clarification....(in general...)
Analog - usually has a dial with a pointer. Like a clock hand.
Digital - a digital readout, or bargraph instead of a pointer.
They are both powered electricaly!!! For most analog guages, losing AC or DC power means they stop working. (Note: There are also mechanical guages, that do not need electricity, but this is not why they are analog)
Digital readouts are all but useless to recognize trends or rates.
This is why the analog guage is still so popular. You can mark
the guage with tape stripes, and see the rate of change, as well as
the present value. If I were leveling off at altitude, and had
to adjust the throttle, the moving pointer makes it so much more
intrinsically easy to accomplish. I would be using a Vertical Velocity Indicator, a pitot static (pressure sensitive) mechanical guage, with
an analog dial.
The big jet liners are like big greyhound busses, definitely not a performance vehicle. A digital flight deck is not as critical an issue there.
One compromise, is to use a bargraph type, or simulated analog display,
to retain the trend information.

Most modern aircraft are equipped with a digital cockpit usually consisting of several large area displays. These displays use a LCD screen and LED backlights. They are lighter and smaller than older CRT displays, or LCDs with florescent tube backlights. In commercial aircraft regulation the digital display systems must be able to operate for a minimum of 30 minutes after a complete loss of power (i.e. engine electrical output), using the remaining battery power.
In the event of failure of the digital displays four back up mechanical (analog) displays are required in a commercial aircraft. If I remember currently they include an airspeed indicator, attitude indicator, altitude indicator, and rate of climb indicator.
