My guess is they will be an absolute mess with color moire all over the place.
This NX9 looks really good and sharp. It is a little disappointing about your contrast being lower. I wonder if you just have a poor unit.
Also Nigel, do you think that eshift is working correctly on that unit. I ask because past comments have said that 8k eshift actually improved the sharpness of the image. I can't see how that would be possible given the way your unit has performed. I really wonder if you just got a lemon. I guess we will have to wait an see when other units arrive.

I guess another question is-- was it similarly recommended to turn off eShift on 1080p content for previous eShift 4k models? In other words, has eShift always been useless with native content?

I don't know that you've received a NX7 yet, but will you be able to compare a eshift turned off 9 vs. the 7? I'm sure a lot of folks will want to know about this comparison.

However, I think you jumped to conclusions a little bit too fast regarding the e-shift. I'm not saying you are wrong and I haven't seen the projector myself. But I'm not convinced that single pixel test patterns is a good way to evaluate it.
The e-shift can only address every other pixel independently in the 8k frame. Therefore it cannot upscale 4k to 8k and render single pixel lines with perfect sharpness. Things like test patterns and computer text should consequently get less sharp. However, movie content does not look like this since it's sampled material. If you zoom in on a small detail in a movie frame so that you readily see the pixels you see that these sharp single pixel transitions don't exist. It could therefore still be the case that even though the test patterns look worse with e-shift small details in actual movie content resolves better or get less jagged. It would thus be very interesting to see highly zoomed in shots of small details in an actual 4k movie frame with and without the e-shift to really see it's effect as it's intended to be used. Would this be possible? 😊
No matter the outcome I'm still very sceptical that the 8k e-shift actually brings any benefits at actual viewing distances. However, I still find the question scientifically interesting and this is after all the av science forum... 😊
The reason I chose to use the Quick Brown Fox test pattern is because it is easiest to see the negative effect on the image that eShift 8K has.
With respect to actual video content, what you are going to see is essentially no difference except for a significant increase in video noise.
Unfortunately, it is practically impossible to photograph the video noise so you really need to see this in person, however it's significantly worse as compared with then eShift is turned off.
And with respect to the difference in video image, well I will let you draw your own conclusions:
JVC RS3000/NX9 | COMPARISON #5 - NO eSHIFT 8K vs eSHIFT 8K
NO ESHIFT 8K:
The fact of the matter is that with ESHIFT 8K turned off the image has less video noise, and is calmer and more stable. Whereas, with ESHIFT 8K turned on there is essentially no increase in sharpness or MTF but there is a significant increase in video noise. Therefore, personally I will be turning it off...
