Thanks for the advise on the HDMI cables, my main concern is that my entertainment rack is to the right of the TV, while the HDMI jacks are on the left of the TV facing right.
So I have a heavy HDMI cable running from my cable box, located to the right of the TV at the top level of the entertainment rack to the TV. The cable is suspended in mid-air and has to make u-turn to plug into the TV's HDMI jack, putting pressure on the jacks at both ends (TV and cable box). My old TV had its jacks in the center so the cable length and weight weren't and issue. I'll just order some longer cables and fix this asap.
I received a PM asking for pictures, so I guess I’ll just post them here just in case anybody else is curious.
My apologies for the picture quality but my old point-and-shoot camera or my cell phone weren’t doing a very good job at getting accurate pictures of what you actually see in person.
Since the test patterns are actually videos, the camera was picking up rapid moving horizontal bands, which do not appear in actual viewing


.
Those lighter horizontal bands that appear at about the center of the screen are actually how the entire screen looks.
I also tried with my phone but again wasn't able to get an accurate picture.

There are no horizontal bands in actual in-person viewing, and the screen isn't green at both edges.
There is some very slight DSE, the pictures (due to the poor camera/cell phone) make it look much worse than it really is in person. I can just barely see it person, and I haven't noticed it while viewing actual content.
I am very satisfied with this TV.
