    The TV is going to need help to get the best picture out of it, start by taking it off Energy Saving Mode, reducing the sharpness and enabling dynamic contrast and backlight after that the picture is set. For $100 TV that is going to be used in the garage its perfect for my situation.

    Excellent Value, all the feature I want and none of the smartv ads I don’t. This is a simple 40” LED 1080p TV. No smart TV complications, boot times, security issues or software updates required. Just turn it on and watch. It works well as a large HD computer monitor for those with older eyes. Plenty bright. Response times seem pretty good for casual and console gamers if you use the game mode. Surprisingly good sound options allowing delay correction to get sound and video to sync up well. Only criticism I have is that the colors get washed out when viewed from an angle. But what can you expect for this price. If color accuracy is paramount you might want to look at the IPS panels by other manufacturers instead. But for my dollar, this screen is the current sweetspot in early 2021.

    This is the 4th Insignia TV I've bought for our family in the past 2 years. Fantastic televisions for the price. Great color and features, well designed remote, easy to set up with Apple TV, Roku, etc. Well worth your investment!

    If you're seeking a "non-smart" TV, this is the ONLY one I've been able to find that doesn't have Google, Fire, Tizen or other "Smart" bloatware. It's Full HD 1080p, not 4K but a great picture.

    Picked up on a whim, for barely over $100 during a Deal of the Day. Everything about this is basic, but I was pleased with the image quality. Screen brightness is always a nitpick for me, and this one is pretty uniform. It’s not 4K, but for a 40” screen that’s really not critical. Highly recommended for a second, or even first, TV depending on your needs!

    I needed a good basic tv to replace a 31" Insignia in the bedroom that was just too hard to see all the detail. This 40" was just right. So light it was easy to mount. The picture is great for me and for this application I didn't need anything higher resolution. Low price was added bonus.
