I have tried to use my grinder machine-DP de still experience symptoms is the same. I think the port monitor's waste is p. tadi make time changes to resolution makes the video signal is missing.
I have tried to use a DP's demo, I still experience the same. I think the IP port of the monitor should not make the change Reis solutions make the image disappear.
I try to use DP line of my demo also experience symptoms was broken again. I think of the monitor port DP seems to be broken, make time to change resolution makes video signal disappears.
