    I was quite disappointed with the performance of this tv. Not being a 'smart' tv does make many irritating differences. I found when a Roku stick is used many features that I had come to expect were missing. No antenna connection could be made through the stick. I had to use the TV remote to access OTA channels. This main feature was a deal breaker. Several similar quirks also presented themselves. I can't recommend this TV for Roku stick use.
