My XG1v4 4K box took the new update to 117.1.1 dated August 6 and I still have the same problems of the box defaulting to 1080p each time I shut the tv off for a period ranging from 15 minutes to overnight. Leaving my 4K capable TV at 1080p still continues to start with a tv screen that slowly begins with 1-2 flashing thin horizontal line(s) and the longer TV is on, moves into a flashing partial screen, and the longer I watch, the worse it becomes until the flashing is so frequent(sometimes more than once a second) This eventually leaves the TV unwatchable in the default 1080p as ever larger portions of the screen intermittantly flashes. Changing the resolution to 2160p 4K clears up this issue, the X1Gv4's menu shows TV is 4K capable and the resolution is available. It's not an HDMI cable, as using 4K clears up the issue, seems more like HDCP issue. I was running this exact system prior to the June update without this problem. I read on another posting, that since these recent updates, older X1 boxes that supported component video out have been broken as well by recent updates, with a black screen being displayed, and only sound.

I wanted to update, since no-one from Xfinity is.
My XG1v4 took the new update to 116.0.1 dated July 8 and I still have the same problems of the box defaulting to 1080p each time I shut the tv off for a period ranging from 15 minutes to overnight, I start with a tv screen that slowly begins with thin lines and the longer TV is on, moves into flashing, partial screen, and the longer I watch, the worse it becomes until the flashing is so frequent TV is unwatchable.
The DVR is set to non powersaving mode
Changing the output to 2160p (60) continues to remedy the flashing, lines, etc. and stops it immediately, that is until I turn off my TV for a period of time
I checked this thread because I just now received a call from 844-536-9475 which purports to be Xfinity Level 2 technical support, but is just a call center in India with nearly impossible to understand the reps, (I tried 3 times, lots of background noise, and reps that read from a script). How can this call center be advanced support?

This has been affecting my 4k X1 DVR in south SFbay since Friday June 26, when I first contacted Xfinity about this, and continues as I write this, even after a later DVR swap.
I was originally told this would be resolved by July 3, on Sunday 7/5 called again, provided a replacement X1 , after the CSR insisted this would resolve the issue.
Speaking to Xfinity reps at Customer Service is a waste of time, even referencing this thread directly, with this ID #3347927 to them does not help. Just met with indifference and they are not being provided information/updates on this issue.
Changing resolution every time the equipment has been off or in standby overnight, or for a long period during the day, (which causes the flashing issue to return) and having to go back and do this picture resolution work-around, is a bother, and not a solution.
This thread hasn't been updated in nearly 2 weeks by Xfinity, when is a fix to this buggy firmware going to be rolled out? My wiring has been checked out my Tivo in another room is at least unaffected....Can the powers-that-be provide at least the courtesy of an update?
Please provide customers a reply, in what timeframe will this now be resolved, since the orignal post states this should have been resolved by July 3
