    Great "dumb" TV. Hooked it up to my Roku speaker and it works perfectly. Picture is clear and it fits just right in my old entertainment center.

    It is a mid-size Full HD TV that's perfect for small rooms. For some reasons I don't prefer smart TV features built in, I'm using Android TV devices instead. So this Insignia is the best fit. Picture quality is great; sound can be better, but is Okay for this price. If you need a TV on a budget, this is a great choice.

    I brought this television for my daughter, she was long overdue for an upgrade. I was surprised by the quality of the picture. The image is very crisp and bright. I wasn't expecting the tv to be this clear. I brought it about 6 months ago, haven't had any issues at all. Connection to wireless internet, for Roku, is great as well.

    I took a chance on this TV as the price was great, and it has features I was looking for. I thought it may too big, as I didn't want a TV that took over the room. It's perfect! The screen is awesome. I have an antenna and a Roku and it's super easy to switch back and forth between the two. The sound is fine! It's a great value for the price!

    Its a dumb tv which is exactly what I wanted. The picture is nice and clear. The sound is fine for normal tv watching but if you want booming stereo get a sound bar. If you want streaming services you will need a fire stick or chromecast.

    Very nice picture. Using as a computer monitor too. A little slow for gaming but works. Excellent for office work and reading. I use a computer sound system so I cannot really judge the sound.
