Like another reviewer I discovered, after buying the set (I did not see the other review prior to buying), that the VESA mount holes were 200 x 100, not 100 x 100 as stated in the specs. So I bought, for another $15, an adapter plate to be able to use my existing stand. The other issue was that it seemed to be impossible to setup the TV without having a Walmart (yes, Walmart, not Sams Club) account - no doubt to track user activity on the TV. I have a Walmart account, but, for whatever reason, had an extremely difficult time getting the TV to recognize the Walmart login (QR code did not work, password did not work, Vizio app did not work). As a guess I changed my Walmart password, then it was possible to link the TV to my Walmart account using the new password.
The TV itself has a great picture - but it should not be this difficult to set it up, and it should not have inaccurate specs as users rely on these when purchasing.
