Our Verdict
Vizio M7 Series Quantum 2020
Vizio M7 Series Quantum 2021
The Vizio M7 Series Quantum 2021 replaces the Vizio M7 Series Quantum 2020, and both TVs are very similar. Local dimming is a bit improved on the 2021 model as there's less blooming, but the local dimming is unremarkable on each. The 2021 model also comes with a remote with voice control, which the 2020 version doesn't have. The 2020 has a slightly quicker response time, and there's less noticeable black smearing with dark objects. Overall, there aren't any major differences, and it's not worth upgrading to the 2021 model if you already have the 2020 one.
