Our Verdict
The M7 Series Quantum 2019 is a great TV for mixed use. It can get fairly bright for an average-lit room and can display deep blacks, which is great for watching movies when in a dark room. Unfortunately, the viewing angles are disappointing and do not favor watching TV from the side, but the TV has an excellent wide color gamut for HDR content and a very low input lag that offers a great gaming experience.
- Excellent low input lag.
- Great color accuracy.
- Excellent color gamut.
- Image degrades at an angle.
- Local dimming performance is just decent.
This a good TV for watching movies. It displays deep, uniform blacks in a dark room thanks to the high native contrast ratio and decent local dimming support. 1080p content looks almost as good as 4k. The TV displays little stutter in movies and can remove 24p judder from most sources. It has a great pre-calibration color accuracy but unfortunately, there's no motion interpolation feature to please the soap opera effect fans.
This is a good TV for watching TV shows. It gets bright enough and can handle reflections well, so it's suitable for most rooms. Unfortunately, this TV has disappointing viewing angles so it's not a good choice if you like to move around while watching your favorite TV show. Also, Vizio's upscaling of lower resolution content is slightly worse than most brands. Finally, its smart interface has a good selection of apps, but you can't add any new ones in case your favorite show moves to a new app.
The M7 Series is a good TV for watching sports. It can get bright enough for most rooms and can handle the reflections of a few extra lights well. Unfortunately, the viewing angles are disappointing and don't favor watching the big game with a group of friends. Also, some demanding sports fans might be disappointed by the amount of dirty screen effect this TV has on darker scenes.
The M657-G0 is an excellent TV for playing video games. It has a remarkably low input lag and a fast response time that delivers responsive gaming experiences with crisp motion. It displays 1080p and 4k resolution well but unfortunately, there are no advanced gaming features like a variable refresh rate or an auto low latency feature like the higher-end models have.
This is a great TV for watching HDR movies. It has a high native contrast ratio, impressive black uniformity, and decent local dimming. It can display deep uniform blacks in a dark room that enhances your HDR movie watching experience. It has a wide color gamut and displays rich, saturated colors but its HDR peak brightness is not always enough to display the latest HDR content with bright highlights as its creator intended it to be.
This TV is excellent for playing HDR video games. It has a fast response time and displays fast-moving content with little blur. When in HDR, the TV has a very low input lag and delivers vivid HDR content with rich, saturated colors thanks to its excellent wide color gamut. In a dark room, where HDR is meant to be watched, blacks are deep and HDR peak brightness is good enough for most HDR games.
This is an impressive TV for use as a PC monitor. It has a very low input lag and feels very responsive. It has a fast response time and displays a fast-moving mouse with just a little blur trail. It has a VA panel and is immune to the burn-in risk and can display chroma 4:4:4 properly so text looks clear. Unfortunately, the image isn't accurate at the sides if you sit up close due to the disappointing viewing angles.

Popular TV Comparisons
The M7 Series Quantum 2019 is a great TV and outperforms many similarly-priced models. See our recommendations for the best TVs, the best 4k TVs, the best 4k gaming TVs.
The Vizio M Series Quantum 2019 is slightly better than the Vizio M7 Series Quantum 2019. The M Series (M8) has more local dimming zones and slightly better contrast ratio and delivers deeper blacks in a dark room, which is important when watching movies or HDR movies. The M7 has just slightly better reflection handling which is important in brighter rooms with many lights.
The Hisense H9F is a bit better than the Vizio M7 Series Quantum 2019 for most uses. The H9F is significantly brighter and it has a faster response time, which is great for gaming or watching sports. The H9F has also a motion interpolation feature to please the soap opera effect fans. The M7 Series has a more versatile black frame insertion feature, which helps make motion crisper but causes duplications.
The Vizio M7 Series Quantum 2019 is slightly better than the Samsung RU8000. The Vizio has a local dimming feature that improves dark room performance and can handle the reflections a bit better than the Samsung. On the other hand, the Samsung has a faster response time that delivers a crisper image in sports and video games, has a motion interpolation feature, and is equipped with FreeSync support for nearly tear-free gaming.
The TCL 6 Series/R625 2019 is a bit better than the Vizio M7 Series Quantum 2019. The TCL can get brighter and can fight the glare of a brighter room with ease. The M7 Series, on the other hand, handles the reflections of a few more lights better, so depending on your room's condition one might be better than the other. The TCL also has an optional motion interpolation feature to please the soap opera effect fans.
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.
