Vizio V4K55M 55″ Class 4K UHD HDR Smart TV

Avoid at all costs unless you literally need a dumb monitor.
Vizio was once a decent brand but is a subpar brand at this point. You would be better off with a “no name” brand in my opinion. My Vizio TVs are: incredibly slow to turn on and respond to input, turn on their backlights at random hours (with no content displayed despite the inpute supposedly being set to Vizio Home), regularly update their firmware (wiping out my preferences), often refuses to respond to casting requests, and is generally underpowered. Videos off of my Plex server used to play without issue, now buffer or will not play at all (but only on my Vizio TVs – which proves it is a Vizio problem). Some problems were resolved by hardwiring the TV, but the problem is that for 4k TV, a WIFI connection that can’t get above 9 Mbits/second means this TV may have a 4k panel but it will never display 4k content unless hardwired. Further, hardwiring the TV does not solve the problem that Vizio’s increasingly clunky user interface consumes so much resources, that the TV is no longer able to display content it used to be able to display.
