The Sony X90K and the Vizio Quantum Pro are similarly priced LCD TVs. The Sony X90K excels in gaming and has a higher overall picture quality, making it a good choice for gamers and those who prioritize image fidelity. It performs well in both dark and bright rooms, suggesting versatility for different lighting conditions. The Vizio Quantum Pro, though not as strong in overall picture quality, offers decent performance, particularly for gaming. However, it may not be the best option for viewing fast-moving sports content or if you're planning to use the TV in a dark room, as it scores lower in those areas than the Sony. The Vizio also has voice commands, a feature not highlighted for the Sony, which might be beneficial for accessibility purposes. If gaming is a priority or you're looking for higher picture quality and bright room performance, go for the Sony X90K. On the other hand, if voice command functionality is important to you, you might prefer the Vizio Quantum Pro. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the Vizio Quantum Pro (LCD) is only fair.
The Sony X90K is valued for its good performance with contrast, local dimming, and black uniformity which are very important for a cinematic experience, and it also offers good color reproduction out of the box. On the other hand, the Vizio Quantum Pro is perceived as fair, partly because while it has very good color volume, its lower contrast, local dimming, and black uniformity may lead to less impressive dark scene rendering.

The Sony X90K (LCD) is good for sports, while the Vizio Quantum Pro (LCD) is only fair.
The Sony X90K delivers a superior sports watching experience due to its excellent motion processing and response time, which minimize motion blur and keep the action crisp, but it has limited viewing angles and only a fair handling of reflections. In contrast, the Vizio Quantum Pro, with its fair motion processing and lower response time, is less equipped to handle fast-paced content smoothly, yet it offers very good handling of reflections and wider viewing angles.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the Vizio Quantum Pro (LCD) is only fair.
The Sony X90K performs better for watching news and TV shows since it has superior upscaling quality and SDR brightness, which are very important for such content, enhancing detail clarity even in lower-resolution broadcasts and providing good visibility in bright rooms. Although the Vizio Quantum Pro offers fair performance, it falls short in these key areas, which may lead to less clear images when upscaling from low-resolution content and lower brightness making it less suitable for well-lit environments.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be very good for bright room, while the Vizio Quantum Pro (LCD) is good.
The Sony X90K excels in a bright room due to its impressive SDR and HDR brightness, along with decent reflection handling, making it very good for viewing in well-lit environments.

Al Griffin | December 2022
"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
About Vizio
Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
