Why should I use and Analog interface LCD monitor?
There are several reasons to use an analog interface display, but there are 3 primary reasons
1 Analog RGB [Red Green Blue] video interface has bee around for about 10 years and has
proven to be a robust, flexible, cost effective video interface that has expanded from VGA [640
x 480] to UXGA [1600x1200] resolution.
2 It is easily supported by 100’s of computer and video card manufacturers
3 It is the defacto video interface [see note below]
Note: There are several companies all competing for the New Digital Standard for video data
displays. Although we are exploring several competing standards we believe that the DVI standard
is going to be the next defacto video standard. When we have proven that compatible component
parts, cables and panels are reasonably available we will have a complete digital panel offering.

Are LCD’s rugged and reliable?
We can only talk from our experience, but after shipping thousands of units of all sizes, LCDs
have proven to be far more reliable then their CRT predecessors.
Aren’t LCD s very expensive?
Although an equivalent LCD solution is more expensive a CRT solution we believe that an LCD is
a better solution for industrial applications, and LCDs have dropped significantly in price over the
past 2 years. Further we expect a continued price reduction.
You also need to consider the total cost of ownership of an LCD. They have a longer life
expectancy then a CRT. Also, if you are considering a touch screen, LCD touch screens are lower
in cost (both new and as replacement parts) then the compound curved CRT touch screens.
Aren’t LCDs difficult to setup?
Using an analog RGB interface you can use the same computers and video cables you are currently
using on your CRT monitor application. Vartech’s LCDs are Plug and Play to your current and
future video display sub system.
