The Vizio M7 Series Quantum 2020 is a good TV for most uses. It has low input lag, a fast response time, and it supports variable refresh rate technology, making it a great option for gaming. It's decent for watching TV shows and sports, as it has good reflection handling but might not be able to overcome intense glare. Its excellent contrast ratio makes it a good choice for watching movies; however, its local dimming is mediocre, and it doesn't get bright enough to deliver a convincing HDR experience.
Was shocked to see the M50Q7-H1 in my local store for under $350, when I was expecting it to be closer to $440. Not sure how this changes the price/performance matrix, but it definitely made me put off buying for another day while I reconsidered which model to get.
