The TCL R648 (LCD) is good for movies & TV, while the Vizio Quantum Pro (LCD) is only fair.
The TCL R648 provides a better experience for movies and cinematic TV due to superior contrast, better local dimming, and stronger black uniformity, which are crucial for deep blacks and detailed dark scenes, while the Vizio Quantum Pro falls short in these areas, though it offers wider viewing angles that could be advantageous in a room with a wide seating arrangement.

The TCL R648 (LCD) and Vizio Quantum Pro (LCD) are both very good for gaming.
The TCL R648 provides a very responsive gaming experience with its very good response time, which indicates how quickly it can change pixels to display content, and its good input lag, which means the TV reacts swiftly to commands from a controller. On the other hand, the Vizio Quantum Pro also boasts very good response time, ensuring smooth motion clarity during gaming, which is essential for fast-paced games, and it likely has good input lag as well, though specific figures are not currently available. Both TVs offer 120Hz refresh rates which can make motion appear more fluid, especially in high frame rate games.

Although they have very similar scores, PerfectRec considers TCL R648 (LCD) to be very good for bright room, while the Vizio Quantum Pro (LCD) is good.
The TCL R648 excels in a bright room due to its superior SDR brightness, helping it overcome ambient light, and its very effective reflection handling minimizes glare. The Vizio Quantum Pro also performs well under bright conditions with high SDR brightness and good reflection handling, but it doesn't reach the peak brightness of the TCL, making it slightly less optimal for very bright environments.

About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
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.
