Hello I am Carlos of Spain. My problem is that I have connected mm400 to one epia m10000 and to a power supply m1 and in the screen leaves interferences to me, as if they were “waves” and not like solving the problem.

Use 60 Hertz of refreshment so that it does not let change it to me, single leaves that option to me. that is normal? and I have it to 800x600 of resolution

the negative that goes to the chassis of the car is the one of mm400 or the one of the power supply? (I have mm400 connected to m1)
