Wondering if anyone got a Circuit for Testing any Monitor Without PC .
Something Like a Screen Saver Circuit to be injected to any Monitor .
Something Like Color Bar Generator Circuit for Testing any Monitor .
Interesting.
I feel that such a unit could easily be made.
Maybe a few square waves on the RGB inputs
would give a sort of tartan pattern.
A lot of monitors have a sort of 'Standby Mode'
which they go into as soon as the computer is
switched off.
I dont know how this is arranged,
but it would have to be addressed.
This circuit not simply made for "any" monitor testing, because the H-frequency and V-freq. (sync pulses) depend from resolution. (H 31.5....100kHz, V 50...120Hz) If You thinking about test equipment,need cca.50...70 variations with frequencies.(most of monitor failures appear only in one or two resolution...)
Some of the new monitors come with self test facility. When not connected to PC, they fill up the screen with up R, G & B colors alternately. Don't know if all monitors have this facility but mine does.
