We also encountered a bug that causes red and green flashes in the opening scene of 'Our Planet'. It seems like there's some improvement as the flashing isn't as noticeable, but it's still present. Update : We've retested the local dimming, specifically the flashing issue in Dolby Vision content. Update : Added the real content local dimming videos. We'll provide links once they're available. Lastly, while it has a full-array local dimming feature, its sub-par implementation results in a lot of blooming around bright objects.Īt the time of writing, this TV is difficult to find through most major retailers. Its VA panel's viewing angles are quite narrow, so it isn't the best option for large seating areas, as the image looks inaccurate when viewed from the side. It handles reflections decently well and gets bright enough to overcome glare, but not quite bright enough to make highlights stand out in HDR content. Its response time is decent, input lag is low, and it supports variable refresh rate technology to reduce screen tearing when gaming. It has an excellent HDR color gamut, allowing it to display rich and saturated colors in HDR content. The Vizio M8 Series Quantum 2020 is a good mid-range 4k TV. Like its predecessor, the Vizio M Series Quantum 2019, it sports a VA panel that can produce deep blacks for a great dark room viewing experience.
