    This is a surprisingly fine TV considering the modest price. The picture quality is very good, especially in "Movie" mode. Sound quality is OK. Setup and installation was easy. The supplied stand supports the TV securely.

    It’s a tv, it does what it’s supposed to do, looks great, love the size, the sale price was absolutely fantastic. The only thing I could have wished for was an led backlight strip, but I knew it didn’t have one when I made my purchase. If you catch this on sale, go for it. When you set up this tv, you should use the Turn Off Loud Noises setting, or whatever it’s called, so that you can better hear dialog.

    Great TV for the price and size. Purchased this for a parent whose old TV quit working. Went to Best Buy and had read and heard good things about Insignia so we decided to purchase this one. It is perfect for their needs. Would definitely recommend Best Buy and this TV to others. Perfect size, not too big and not too small, and has a great picture.

    I'm very pleased with my 40 inch Insignia tv. The picture is crisp and clear and has very nice color resolution. The setup was amazingly easy and gives you the option of voice promps upon setup. It does not have roku or smart technology but you can add a roku or fire stick if you want. At 149.00 you can't beat it.

    Insignia makes fantastic TV's! I have three different sizes. They all are crystal clear and if you get one with Fire TV installed, as this one has, you don't need a Fire stick. Built right in. The voice command is awesome. I have a analog antennae connected, and if you are watching any app or show, just press the voice control button and say a channel number. Wolla! Goes right to it. Never miss a show since this is super easy to set up with your Amazon account and sync your other Fire TV's with it without having to set everything up separately. You may have to re-enter passwords for different apps as expected since you are using a new device. Highly recommended purchase from Beast Buy!

    Great TV for Price , Audio Could be Better

    Would have given 5 stars but find the audio lacking. I bought this model because I like my first Insignia 39", purchased in 2012, and still going strong. However, in comparison to older one, the volume & sound quality is not great. Both TV's have Roku (no cable). On new model volume is usually at 19-24, compared to 8-12 on older one. Quality & clarity of sound is not great & there isn't a discernible difference between the audio options, ie. standard, music, news. Picture quality is good.

    I bought this to replace an older 32" tv that I had brought to my basement to hang up but sat around for a while and got scratches across the screen that damaged it. This was a huge difference as the older LCD weighed more than this and it was smaller!! I'm impressed by its performance and the fact that I have no issues with it receiving channels, the Roku, or anything else I plug into it.

    Good size high res TV that fit my TV cabinet. The diagonal on this screen was much bigger than the 37" I had. Thin bevel frame disappears when TV is on. Only drawback is the remote control. The receiver range is not very wide. You have to be in front of TV for remote to work the first try. Not sure why that is. I paired a soundbar with this product to enhance the sound and effects.

    I didn't know what to expect from an Insignia branded television. I was pleasantly surprised. The 40" tv works great as well as being a good value for the price. It's not a 'smart' tv but with an external media player, I have what I need. I have one criticism. The input labeling is seriously deficient.

    One small glitch

    It's a great TV, easy to set-up, and perfect for my spare room. The only issue I have is that the USB port is just a plug-in for a photo flash drive and not useful for connecting another device. I need a TV that I can plug my digital antenna into (they all seem to have USB instead of HDMI for some reason). When cable is down (which is often), I like to have access to local channels via antenna. I thought this would work, but it doesn't. But this was inexpensive and a great TV for streaming, so I'm happy overall. Still searching for the elusive 'cheap' TV with a USB port...
