The Vizio Quantum QLED is an entry-level LED TV released in 2023. It's one of only two Vizio TVs released in 2023, at least at the time of publication, sitting below the Vizio Quantum Pro QLED. It offers Quantum Dot colors and a wide selection of gaming features, including 1080p @ 120Hz gaming from the latest consoles and VRR support. Unfortunately, it's still powered by Vizio's lackluster SmartCast smart interface. It's available in 55-inch, 65-inch, and 75-inch sizes, so there's something for most rooms.
Our Verdict
The Vizio Quantum is an alright TV overall. It's best suited for watching sports or shows in a moderately-lit room, as it gets bright enough to overcome some glare. It doesn't look good in a dark room due to its terrible contrast and lack of a local dimming feature, so it's a disappointing choice for a home theater setup. It has a surprisingly good array of gaming features, though, and with its low input lag, it's an okay choice for casual gamers.
- Wide viewing angle.
- Terrible contrast.
- SmartCast interface has a limited selection of streaming apps.
- Poor speaker quality.
The Vizio Quantum is an okay TV for watching shows in a moderately-lit room. It's bright enough to overcome some glare from windows or bright lights, but it has just decent reflection handling. On the other hand, its image processing features are very basic, and it can't smooth out or upscale low-quality or low-resolution content well. Its smart features are also limited, as you can't add new streaming channels, and only a few are available.
- Wide viewing angle.
- SmartCast interface has a limited selection of streaming apps.
- Very limited image processing.
- Poor speaker quality.
The Vizio Quantum is a decent choice for watching sports in a moderately-lit room. It's bright enough to overcome some glare from windows or bright lights, but it has just decent reflection handling. It has a great viewing angle, which makes it a great choice for afternoon parties as you won't have to fight over the best spot in the room; everyone watching will enjoy a consistent image. Unfortunately, there's some noticeable dirty screen effect in the center, and the smart interface has a very limited selection of apps, and many sports apps aren't available.

The Vizio Quantum TV is alright for gaming. It has incredibly low input lag, ensuring a responsive gaming experience with very little input delay. There's also a surprisingly good array of extra gaming features, including VRR support and a 1080p @ 120Hz mode, which is great for performance-driven games. It looks best in a moderately lit room, as it gets bright enough to overcome glare, but it looks bad in a dark room due to its low contrast and lack of a local dimming feature.

The Vizio Quantum is a disappointing choice for watching movies in a dark room. It has terrible contrast and sub-par black uniformity, so dark or dim scenes look washed out. It also lacks a local dimming feature and it can't get very bright in HDR, so although most midtones are displayed well, bright highlights don't stand out in any way. Despite its wide color gamut, HDR in general looks flat and dull and adds little to the experience.
- Excellent color gamut.
- Terrible contrast.
- SmartCast interface has a limited selection of streaming apps.
- No local dimming.
- Low peak brightness in HDR.
- Poor speaker quality.
The Vizio Quantum is an okay TV for gaming in HDR, but mainly due to its raw gaming performance, as HDR adds very little to the experience. It has incredibly low input lag and a wide array of gaming features, including VRR support to reduce tearing and a 1080p @ 120Hz gaming mode. Despite its wide color gamut, HDR looks dull and flat as it has terrible contrast, low peak brightness, and no local dimming feature. Bright highlights don't stand out, and colors aren't bright or vibrant.
- Excellent color gamut.
- Incredibly low input lag.
- 1080p @ 120Hz mode.
- VRR support.
- Terrible contrast.
- No local dimming.
- Low peak brightness in HDR.

The Vizio Quantum is a very good TV for use as a PC monitor. It has incredibly low input lag, ensuring a smooth and responsive desktop experience. With its wide viewing angle, you can sit close to the screen without losing uniformity at the edges. Speaking of, it has just decent uniformity, as the sides of the screen are darker than the center, but there's relatively little dirty screen effect in the center. It displays chroma 4:4:4 or RGB signals properly, which is essential for clear text from a PC.

- Incredibly low input lag.
- Chroma 4:4:4 is displayed properly for clear text from a PC.
- 1080p @ 120Hz mode.

The step-up Vizio Quantum Pro QLED is significantly better than the Vizio Quantum QLED. The Pro model gets a lot brighter, so it can handle more glare in a bright room, and HDR looks more vivid overall. The Pro also adds a full array local dimming feature, and while this increases the amount of blooming around bright objects, it also drastically increases the TV's dynamic range, so bright highlights stand out in bright scenes, and dark scenes aren't as washed out.
The Vizio V Series 2022 is better than the Vizio Quantum QLED only if you're in a dark room; for everyone else, the Quantum is a better choice. The Quantum has a much wider viewing angle and better uniformity, and it gets brighter to overcome glare in a bright room. The Quantum is also a bit better for gamers, thanks to its support for 1080p @ 120Hz gaming. On the other hand, the older V Series is only better for use in a dark room, as it has much higher contrast and better black uniformity.
Unless you're in a completely dark room, the Vizio Quantum QLED is slightly better than the Amazon Fire TV 4-Series. The Vizio has much better accuracy even before it's calibrated and has a much wider color gamut. The Vizio also has a very wide viewing angle, which is great if you have a wide seating arrangement, as the image doesn't look washed out at an angle.
The Hisense A65K is much better than the Vizio Quantum QLED. The Hisense has a much higher contrast ratio, delivering deeper blacks that aren't washed out as much when bright highlights are on the screen. The Hisense also has better processing when upscaling low-resolution content. Finally, the Hisense features a far more robust smart interface with a huge selection of streaming apps, so you can quickly find your favorite shows directly on the TV without having to cast content from your phone.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
