???
The 12volt 4amp external switching power supply for my lcd monitor burned out.
On the back it states it is a "level 3"

I found another 12volt 4amp switching power supply that states it is a
"level 1" power supply

Does anyone know the difference between these and if it is risky to
run the lcd with a level 1 power supply?
