Going into this review, I was prepared to lay into the Sony X90L with some pretty stiff criticism. On paper, the Sony X90L didn’t appear to be prepared to ward off competition from such value hits as the TCL QM8 and Hisense U8K. Now that I’ve measured the Sony X90L and watched it for almost three weeks straight? Well, you are definitely going to want to read what I have to say.
This year was looking pretty similar, at least on paper. Both the Hisense U8K and TCL QM8 have mini-LED backlight systems broken down into an impressive number of dimming zones. In theory, those mini-LED backlights and high zone counts should provide pictures with high brightness while maintaining great black levels and reduced blooming and halo effects commonly associated with LED-backlit TVs.
By comparison, the Sony X90L uses a standard LED backlighting system with significantly fewer local dimming zones — about 80 zones for the 65-inch variant I reviewed. So, reading purely from the specs sheets, it looks like the TCL and Hisense competition have better tech for less money.
From a measurements perspective, the Sony may not appear to be as intensely bright as the charts for the TCL QM8 and Hisense U8K make those TVs appear to be. But when it comes to real-world content viewing, the X90L appears to be just as bright in most viewing situations. And when it comes to accuracy? The Sony X90L handily defeats both the TCL and Hisense. Seeing this kind of accuracy in a TV at this price is, frankly, hard to believe. I think that’s really exciting.
So at this point in the review process, the Sony X90L was looking very promising. But I wanted to see how it performed with actual content of varying types and, of course, in the back of my mind, I was concerned about how its black levels would turn out. How much blooming would we see? And would that blooming detract from the other aspects of its otherwise excellent performance?
As for gaming — well, you guys know I don’t dive super deep into the gaming realm, but I was able to determine that input lag on the two HDMI 2.1 ports was about 19 milliseconds at 4K 60Hz, and just a touch lower at 120Hz. The TV does support VRR, but when you engage VRR, most of the processing gets scaled way back, and that includes the local dimming system, so contrast takes a significant hit. As a matter of fact, HDR gaming in general, even without VRR, doesn’t have the contrast I want because the game mode chops down the local dimming system enough that you lose a significant amount of pop. That’s really the only instance in which the lack of a mini-LED backlight system shows through, frankly. The X90L isn’t a bad gaming TV per se, it’s just not as high-performance as other TVs in this price class. It does have a nice gaming dashboard, though, which is shared across the Sony line this year.
As for sound? I suggest you consider adding a soundbar if you can. The TV’s legs allow two heights, the taller of which is enough to accommodate a low-profile soundbar. Even one of Sony’s basic bars is going to really pump up the audio for this TV. The onboard audio is passable, but I got used to having a soundbar and I just couldn’t go back.
