I just noticed something with my 65" H7150.
I have a fairly simple set up. A Roku 3 connected, via HDMI, to the HDMI 1 input on the television. I also have a Blu ray player connected, via HDMI, to the HDMI 2 input on the television. I also use a Harmony 650 universal remote.
When I select Watch Roku (input HDMI 1), everything turns on accordingly however, when I access the picture menu of the Samsung TV, White Balance and Gamma DO NOT work. They are not disabled, they simply don't have any effect on the picture at all (turning 10 point on or off or moving the Gamma setting up or down is pretty noticeable when they're working properly).
With everything still on, if I select a different Source from the Samsung source menu (HDMI 2) and then return to the Roku input (HDMI 1), White Balance and Gamma then work properly.
With HDMI 2, the Blu ray, everything works as it should every single time it's turned on.
I tried connecting the Roku to HDMI 3 and had the exact same issue as with HDMI 1.
I've tried different HDMI cables. I rest the Roku and the TV and still, this weird thing keeps happening...
Does anyone have any thoughts on this???
Thanks in advance.
