XG1v4 Streaming 4K Causes Pixelation

Can you help me out?  Do you have a newer DVR model or a fix for this issue?

Problem:

XG1v4 DVR causes white flickering pixels in various sections of the picture when streaming 4K content through the DVR.  Most noticeable in dark scenes.

My setup:

The DVR is directly connected to the TV's 4K 120Hz HDMI IN.  No receiver being used.

This problem only occurs when the DVR is streaming the 4K content.

If I stream 4K using the TV only and no DVR connected the image is perfect but this is not convenient.

Swapping HDMI cables and using Ultra High Speed certified 8K,  4k 120 Hz. cables made no difference.  Problem still occurs.

I can share an 8 second video that shows the problem if you tell me where to send the video

DVR box is XG1v4-A:

Release version: 147.0.1

Release Timestamp: 4/25/22 9:34 am

STB Timestamp: Thu 24 Mar 2022 10:42:39 PM UTC

STB Version: AX014AN_4.12p20s1_PROD_sey

XRE Protocol Version: 2.8.0

Receiver: Native Version 4.12.0

Environment: h2e-ax

I can provide Device MAC, DOCSIS MAC, CC SN, and SN if needed.

Thanks.

I had this exact problem with my Tivo DVR to a brand-new Samsung OLED TV 6 months ago.  I changed HDMI ports with no resolution.  Then I replaced the new 8K HDMI cable I purchased with other HDMI cables.  After trying four cables, I now have a perfect picture.  Changing back to my expensive 4K cable and the problem returns.  The degree of pixelation would change with each cable, until I found the one that has now been working without any issues.

@bvwhitney​  what is the brand of the cable that works for you and where did you buy it?   What is the rating on the cable?  8K, 4K, lower?  Are you sure you are watching the content in 4K mode with the cable that works?   If I step down my TV to regular HD instead of selecting 4K, the pixelation problem goes away but so does the great 4K picture detail.  That defeats the purpose of having a 4K TV.

I wish I knew the brand of cable that is working, but there are no markings on the cable to identify the manufacturer.  I have a box of about 20 HDMI cables, and I just started testing to find one that would work.  All cables I tested work fine at FHD and HD, but until I found the one that worked, I would get sparkles in my screen on 4K video sources.  I am certain I was using 4K sources, via streaming from the DVR.  I have Xfinity as my cable company only offers HD video (720P) except for a few local channels that are FHD (1080I).  I can stream the few available 4K videos on Netflix (premium member) and Amazon from my Tivo without problems.

I recently purchased a Netflix Premium subscription.  I get no pixelation whatsoever streaming 4K Netflix through the DVR.  I have only found the pixelation to occur with a combination of certain Amazon 4K content streaming through the DVR but not all 4K content.  I wonder if the creation of 4K content can vary in quality or process which causes the issue in some 4K versions.  If you have an Amazon Prime subscription, try streaming Bosch UHD 4K through the DVR.  Scan for dark scenes then look near the top of the image slightly to the left of center.  I get at least 30 specs of white flicking light sometimes moving around and sometimes fixed in one position on the screen.  Please let me know what happens.
