Expert Reviews


I found the VIZIO M321i-A2 to be one of the best 32" HDTVs at this price-point. It offers a stellar appeal and build quality while harnessing the Smart technology and features that you could ask....

Gorgeous styling thin profile
Topnotch build quality
Excellent panel performance
Builtin WiFi Smart TV functionality
Decent integrated speakers
No physical buttons on HDTV chassis (must use remote)
Would prefer 4 HDMIs instead of only 3
Minor backlight vignetting is noticeable in brighter backgrounds
No integrated web browsing application
Vizio support isn't available by phone

Just because this TV is not as expensive as higher-end LEDs, that doesn't mean you won't be getting high quality video as well as immersive features...
