Next up, there are the display technology issues we didn't like with the otherwise excellent X930/40D flagship models. Most fundamentally, there is the quality of the X930D variant's local dimming technology. It falls a bit flat even by the standards of premium edge-lit 4K TVs. Samsung has managed better than this in its KS9000 edge-lit 2016 SUHD TV and Sony could have done the same considering the caliber of their consumer tech development reputation. However, they apparently didn't and as a result, the X930D in particular presents too much blooming due to what we think are the large dimming zones and while this effect isn't so notable for lower lighting situations in the screen, it becomes notable during particular highlights of peak brightness. We should note that the 75 inch X940D variant of this line doesn't suffer from the local dimming problems in the X930D. Due to its full-array LED backlighting and a larger quantity of better compartmentalized local dimming zones, it definitely shows its superiority in this regard.
