brightsign xt1144 - No video resolution

I have brightsign xt1144 attached to an Onkyo receiver that is connected with a 4K TV Box and Nvidia Shield.  Although I set it with the right resolution that is 3840X2160 60P, the image switches from white to black several times.  In few occasions, I will get the image but most of the times, it looks like that the receiver can not fix on that resolution.  I tried to change from 60P, to 59.49 to 30 to 24 and to use the option to force resolution but without success.  Any help would be appreciated.
