Great TV for the Price
This was my first large tv. So far, it seems to be working very well It was a pretty easy setup. Given the size (55"), I was able to do it myself. The brightness, color and sound seems to be excellent. I am also loving that it is HomeKit compatible

Buy this TV if you great value for features/colors
I love M Series M8 TV. This tv does it all gaming, movies, photos, and karaoke. My only issue is with the speakers being really low volume. I love all the built in gaming features HDR10/10 /Dolby Vision/HDMI 2.1, VRR, ALLM, AMD Freesync, and more. The TV gets 600 to 800 nits and the quantum color work perfectly for true color. So I went to get a sound bar now its like those $2000 TVs maybe even better. I put this TV up against TCL/Hisense/LG models and this Vizio beat them at price/features/wide color gamut. Full Array Local dimming.
