TCL 5-Series S555 65" (QLED) vs Vizio OLED 55"

The Verdict

The TCL 5-Series S555 and Vizio OLED represent different value propositions at dramatically different sizes and prices. TCL's 65-inch QLED panel delivers brighter peak brightness at 800 nits versus Vizio's 600 nits, making it superior for bright rooms and HDR content pop. Its larger 65-inch screen provides significantly more immersive viewing for the same $599 price point. However, Vizio's OLED technology offers inherent advantages: perfect blacks, infinite contrast ratios, and superior color accuracy that QLED simply cannot match. Vizio's panel is also thinner at 1.5 inches and lighter at 33.5 lbs, plus it includes Dolby Atmos audio support versus TCL's basic 2.0ch setup. Gaming performance favors TCL slightly with 8ms input lag compared to Vizio's 10ms, though both are responsive. The 10-inch screen size gap is meaningful - 65 inches versus 55 inches creates entirely different viewing experiences. TCL wins decisively on value per inch and raw brightness for mainstream buyers. Vizio justifies its $400 premium for OLED picture quality and build refinement, appealing to home theater enthusiasts. For most living rooms seeking maximum screen size and brightness on a budget, TCL delivers better overall value. For those prioritizing picture quality above all else and accepting the smaller footprint, Vizio's OLED technology is worth the investment.
