XG1V4 box HDMI handshake problem
I have seen several messages/questions in this forum about problems with the XG1V4 box losing its HDMI connection with the TV. But in none of those threads does there appear to be a resolution, so I am going to try to bring up the question/problem again.
My setup:
XG1V4 connected via UHD high-speed HDMI cable to Samsung UN65JU6500 TV.
Problem:
The TV and XG1V4 work fine together for the whole day. Then, the next morning, when I turn the TV on I get a black screen. I can resolve the problem by rebooting the XG1V4 (obviously not an acceptable way of dealing with the problem). Occassionally, without needing to reboot, I can get the box and the TV to communicate correctly by first connecting the XG1V4 to a much older non-UHD Samsung TV, getting that TV to show correctly, and then connecting the XG1V4 to the UN65JU6500. But that doesn't always work. In any event, even when I do get it to work correctly, it quits working again the next morning. Rinse and repeat.
Elsewhere on these forums there have been a couple of suggested fixes. First, turn off PowerSave. I have done that. Second, make sure you have a UHD high-speed cable. I have done that. Third, make sure that you have the latest firmware on the TV and on the XG1V4 box. I have done that.
From reading the various threads on this issue, it appears that it is an HDCP 2.2 issue that is causing the XG1V4 and the TV to have a problem establishing an HDMI handshake. And several Comcast employees suggested that the problem has been sent back to the tech folks to find a solution. But unless I have missed it, I don't see any notice of a resolution.....

I am back to using 2 remotes to manually sequence the on off and audio function the the crackerjack tech guys at Samsung cannot seem to figure out. Comcast is NOT the issue being a simple portal to the service and the box should never be off anyway...

have you tried setting up your TV while watching netflix in 4k (brightness, contrast, gamma, sharpness, etc)? Netflix offers test patterns to assist in the calibration. The direct streaming does not require that calibration but probably should be checked using the Netflix test patterns.

Stop using your ARC HDMI ports go to the general HDMI ports and go to 2 clickers...use one to start the functions and the other to correct the TV and for the remainder of when the TV is on you are back to the Comcast clicker...rinse and repeat every time you turn on the TV.

If I’m watching 4K streaming and Comcast 4K I would hope it would be the same quality. My tv is calibrated. What’s also interesting Comcast 4K Netflix just offers HDR where the streaming offers Dolby Atmos. Seems weak on Comcast’s part.

I do not use my ARC HDMI.
I plug my cable box into my Yamaha then plug my Yamaha into another HDMI port in my Samsung Q9. My Comcast remote lights up the TV and turns on the receiver. I then take the TV remote go to settings and switch the sound input from TV speakers to my Yamaha. From there all control can be done with my cable remote. (Volume channel launch Netflix)
When I shut off the tv with the cable remote I need to do the whole process again next time I turn it on.
