Looks like Rtings just updated this page today.
One difference that I see is that they changed their mid-range recommendation from the Sony X900e to the Sony x930e.
Budget choice is still the TCL P607.
Down below in the list of sets that didn't quite make the cut, they now have this to say about the Sony x900e:
Here is my question about this though: On the TCL P607, game mode turns off the FALD (local dimming). It has better input lag, but my understanding of the x900e is that game mode keeps the FALD on. Doesn't FALD improve the quality of the HDR?
I don't have a 4k TV yet, but one of the reasons I was leaning toward the x900e, even with the higher price, is because in theory it should have a better HDR picture in game mode. It also seems like the Sony set has really fantastic motion handling, amazing 1080p upscaling, and better grey uniformity.
But maybe I am just being seduced by these fancy specs. Has anyone actually seen the TCL P607 in person and been able to compare it to something higher end like the Sony x900e?
