My device is set 3840X2160 60hx but every time I turn the device off then turn it back on the resolution change back to 1080p. Any idea
On this issue, we tested several different brands of TV, did not appear this problem. Will you directly connect the TV?or your device connect MARANTZ SR7011, MARANTZ SR7011 connected to the TV, if so, you can try to directly connect TV.
