3m 15" touch screen trying to use a universal power adaptor that runs 12v 500ma max. Screen needs 12v 2.0a. Screen stays black. power led is on.
Is this due to the amperes? I thought running higher would be okay, but running under would not

you are running the correct voltage but not the correct amps...
500 ma (milliamps) is 1/4th of 2a or .5
you need four times the amps you have now. i do not agree that higher is ok, use the right power supply. its good for long term health too.

Volts = electrical pressure
Amps = electrical flowrate
Would the wrong flowrate be a good thing or a bad thing?
Use the right adaptor.
Always use the right adaptor!

500 ma is NOT greater than 2.0 Amps.
500 ma is 0.5 Amps

Answer is staring you in the face. Stop being a 'techie' and start thinking 'normally'.
