I have received my XG1v4 4K box and have performed some testing to compare the video quality I get from multiple display resolution settings. Following are my findings:
If I select one of the 4K settings, the XG1v4 outputs 4K to the TV at all times, regardless of the original content resolution. In other words, the cable box is upscaling everything to 4K regardless of the content... Even for regular 1080p station broadcasts. I know this because my projector has an information screen which shows the resolution of the input it is receiving.
If I select the 1080p or 1080i display setting, the video I receive is significantly better... Better contrast and better clarity. This is because I have the XG1v4 installed in my Home Theater and it is connected to a high-end 4K projector which does an amazing job of 4K upscaling of 1080p content to my 145" screen. In this case, it certainly does a far better job of 4K upscaling than the XG1v4 box does.
If I select one of the 4K settings, Netflix doesn't show the UHD content. Even the Netflix content which should be UHD (like House of Cards, Stranger Things, and etc) shows up as HD 5.1 rather than UHD. I also tried unplugging the power after selecting the 4K display option in order to reset the XG1v4 box. That didn't help.
If I select one of the 4K settings, I'm still not seeing any 4K Olympics options in the Olympics On Demand. I don't know if this content has shown up yet so it may not be there for anybody at this point. I also tried unplugging the power after selecting the 4K display option in order to reset the XG1v4 box. That didn't help.
As a side item, I was surprised by the fact that all of my DVR recordings showed up on the new unit. Before I replaced my previous DVR, I did the "SYNC" option in the settings. When I installed the new 4K box, all of my recordings are accessible. I assume that everything was synced in the cloud and that is what made this possible.
Based on these findings, until there is native 4K content, it appears that I am better off leaving the display setting at 1080p60 so that my projector can do the upscaling of the 1080p content. I was really hoping that it would output the original resolution for everything... 1080p for 1080p content and 4K for 4K content. This is a huge disappointment as I was looking forward to using this box for broadcast 4K.
I can confirm these findings on my B6 OLED. I set up the box a couple days ago on Monday and naturally set it to the highest resolution setting. Directly connected to the TV. Couldn't really tell a difference in image quality since I personally don't watch a lot of cable TV. However, true to my nature, I did some 720p vs 1080i testing this morning by comparing AMC (Ch 171) and NBCSN (174) and trying various settings on the XG1v4.
Set to 2160p60 - Image noticeably flat and dull; lacking color, contrast, brightness and sharpness.
Set to 720p - Image noticeably better; improved color and contrast, slightly improved brightness, and sharpness seemed more or less the same.
Set to 1080i - Same as above, except color and contrast seems slightly worse.
Set to 1080p60 - Everything clearly improved; color, contrast, brightness and sharpness. Very obvious 'day and night' difference.
So it appears that the XG1v4 is optimized for 1080p. The upscaler doesn't do nearly as good a job as the TV's.
I made a separate thread about this, but the solution to this would have been a native resolution setting. Because reading through this thread I just learned that the Olympics are in 4K. I just tried watching it with the box set to 1080p60 and I got a notification saying I need to set it to 4K. I guess it's not a big deal, but still.
Did you enable Deep/UHD Color when testing 2160?
