    Insignia 40" not a smart TV

    I like the older style remote (with number buttons). The picture is great and it makes one heck of monitor for my laptop. I was surprised it uses more electricity than the 43" TV I have (40W compared to 28W) but it is an older model. Setup was easy.

    A good, basic non-smart TV that works perfectly in the bedroom or as a smaller living room TV. I was impressed with how easy setup was and everything worked well. The picture is also pretty good for being a cheap option.

    Ordered this TV online from Best Buys and was delivered the next day. Very pleased with easy set up. After a few minor adjustments to get the picture the way like it, it comes in very well,. So far, we are pleased with the TV. We have good luck with this brand.

    Bought for my elderly 85 year old father-in-law. Excellent picture, easy to use, easy to set up. Non-smart TV which is why we bought it.

    I purchased this tv after my old 32" started acting up and have not been disappointed so far. This is my first Insignia brand and I thought that I would give it a try after reading a lot of the amazing reviews on this product. The 1080p picture is awesome and I can actually hear the audio through the built in speakers, which is a nice improvement from my smaller tv that I previously used. Think it could benefit from a decent soundbar, but it does sound good. If you are just looking for a 1080p tv that is not a smart tv, then I would definitely recommend this best buy brand.

    Old TV went out was a 32 inch. Decided to get a bigger picture, after checking other stores Best Buy was the better choice. Great price, quality and picture.

    Bought this as a replacement bedroom TV and it is great. Picture is vivid and the sound is good....esp since it's a bedroom TV I don't need loud volume. Easy set up for one person....who's not a techie. :)

    I purchase this TV for my son for his dorm room. It worked as expected but this best thing about it was the light weight. Very easy to move around and the picture quality was pretty good for the price.

    Great deal, great tv. Got as a gift for my elderly father who is not very tech savvy. Does not need a smart tv, just his cable box (which already has built-in option for app installation). Good quality, nice picture. Easy to operate.

    Bought this for our 14 year old son's room for his (basic) video gaming. It's a great size, and he loves it. Video quality is great. It was easy to set up out and connect, and it was a great price!

    Have had this TV for about 2 weeks & so far it's great. Didn't want a smart TV so this fit the bill perfectly for our bedroom. Great picture & works very well with the Roku device we use for streaming. Price was excellent as well.

    We were worried that we would have to sacrifice quality or features to get a low price. This was not our experience with this purchase. We are very happy. Clear beautiful picture, easy to operate, works great with gaming as well.

    Bright, detailed picture , easy to understand remote and menus. Overall a great buy. When you set it up, for best picture quality be sure to choose a different Picture Mode than the default "Energy Savings" in the Settings. Some reviewers here mention a lack of picture quality; that's because they didn't do this.

    I'm extremely pleased with my new Insignia flatscreen HDTV. It has a superb picture and is very easy to operate. The set-up and maintenance are much less complicated than a Smart TV and I like it that way.

    This is a great replacement TV. Great picture, easy to set up and it actually talks. And the price was under $300. Would recommend this 100% I had 2 Samsung before and the screen went out on both.

    This was a replacement for a 2yo vizio smart TV that vizio bricked after an update. Great basic TV, good picture, decent sound and great price. Would have liked it if insignia did this size 1080p or 4k in a smart TV but it is what it is.
