if it is a good display and if you have more  displays of the same ..make a
test plug  so you can get average readings of at least three units and take
the average   ...... use more if you have them to average...is the power
voltage at the right levels?+vdc?    then go for it ....sometimes when the
manful set out spec. sheets  seldom   very seldom they are right .....within
specs they say.....hehe....oh well .....tim
