I stand by my original claim that the Sony does a better job when fed a 1080p signal, although I do this conversion in the AVR.

Several days ago I reported that PQ is not as good if you up-convert to 1080p/24 in the AVR instead of 1080p. In other words, if the signal is 1080p/60, and it gets converted to 1080p/24, the PQ is degraded.

Sorry for the confusion.
Thanks. Ill switch from Auto to 1080p on my denon receiver and see how it plays. Right now my Tv and Xbox One, and Fire TV all go through the Denon receiver.

It could be placebo effect, but I swear my PQ is even better now that I changed the screen setting to +1. Thanks, Geoff!

Yeah, the improvement could well be all in your head! But what you've done is remove another layer of processing, as the TV was essentially cropping the image (even if it was only a few pixels) and rescaling it to the native resolution of the screen. It still has to upscale a "+1" 1080p image of course, but now you're getting the cleanest possible upscale from HD to UHD because 1920x1080 to 3840x2160 is directly proportional.

For reference when viewing a 1080p image:

+1 gives you no overscan, you're getting every pixel of the 1920x1080 source.

Normal crops approximately 20 pixels from top and bottom, 30p from side to side, so you're looking at a 1860x1040 resolution image.

-1 crops approx. 40p top/bottom and 65p from side to side, so you're essentially getting 1790x1000. Not good.

Both of the latter modes make for a trickier, non-linear upscale. You can see the effect on fine detail by pulling up a test pattern with single-pixel patterns and changing the display setting on the fly, you'll see weird patterns appear in the fine single-pixel mesh which disappear with +1. I recommend the S&M 'Framing' pattern, it's got a donut-shaped ring in the middle which shows up the scaling artefacts very well.
