After about an hour of tinkering I'm finding that to be the case. Anything but 1080 and 4K is wonky. I freaking love how fluid 1080p 120hz feels. I can't wait to see 1440p at 120. Sitting about 8 feet back 1080p looks really good, but going between 4K and 1080, the IQ difference stands out more. 1440 seems like a happy medium for me and the performance/iq I'm after.
