In our tests, the Vizio Quantum Pro TV offers a bright, high-contrast image for the price, making it a solid midpriced option. The TV preserves pictures well from off-angles, providing a good viewing experience. However, the color accuracy is slightly less accurate compared to other models in a similar price range. One drawback is that the Quantum Pro is only available in two sizes, 65-inch and 75-inch, limiting options for those looking for a smaller TV. The TV’s predecessor, the M-Series Quantum X, is available in a 50-inch size for those seeking a smaller option.
The Quantum Pro TV features a sleek design with a simple remote and adjustable stand, making it easy to set up. The TV’s slim feet are height-adjustable, allowing space for a soundbar underneath the set. The remote is user-friendly and includes shortcuts to popular streaming services. It uses Vizio’s SmartCast system, which may require some adjustment for those used to mainstream smart TV systems like Roku or Google TV. While SmartCast is user-friendly, it features more prominent ads on the home screen compared to other systems, such as Roku.
The Quantum Pro distinguishes itself from other Vizio TVs by offering full-array local dimming, enhancing LCD picture quality. It also boasts a 120Hz refresh rate, four HDMI inputs, and a Vizio voice remote. The TV can handle 4K 120Hz sources for smoother gaming experiences, although this feature is only available on one of its HDMI inputs. While lacking mini-LED technology found in other models, the Quantum Pro remains competitively priced compared to other favorites in its price range, such as the TCL QM8 or Hisense U8K.
In comparison tests with other TVs in its class, the Vizio Quantum Pro delivers a bright, relatively accurate picture with better contrast than some competitors like the Roku Plus Series. However, there were some drawbacks noted during testing, such as overly bright images in the middle brightness ranges and slightly undersaturated colors. Picture quality for gaming was optimal when using a combination of the Calibrated mode and Gaming/PC mode, which reduced input lag and optimized picture quality. Despite some minor picture quality issues, the Quantum Pro performed well overall for gaming.
The Quantum Pro excelled in maintaining color saturation from extreme off-angles and displayed good uniformity across the screen. Despite some inaccuracies in EOTF and a slight blue cast to the grayscale in certain modes, the TV performed well in various picture settings and measurements. Overall, the Vizio Quantum Pro is a solid choice for those seeking a quality TV without breaking the bank, especially if one of the available size options works for their needs. With its high-contrast image, adaptable design, and gaming-friendly features, the Quantum Pro offers a good value for its price point.
