Best 40 Inch LED TVs Review

If you're not already familiar with LED, it's something that has been a common feature in some of the best televisions for many years now. LED stands for Light-Emitting Diode, and in a TV, the LED panel serves as a backlight. Various different areas of the screen are served by the different diodes and the brightness and color are controlled by it. It's a great feature to have in a TV because it's usually a system that will have a high range of brightness, which means that all of the colors will be given a solid amount of attention. The picture quality is very strong because of this with everything looking clear and realistic.

So if you're looking for a good 40 inch TV, you've made the right decision by choosing LED. And 40 inches is a good size to go for, it's big enough to give you an immersive experience but not so big that it takes up half the room.

40 Inch LED TV Buying Guide

What to Look for in a 40 Inch LED TV:

So as we've established, there are quite a few very good 40-inch LED UHD TVs to choose from here and they all have their own advantages and disadvantages. But what the ultimate decision is going to come down to, is what exactly you are looking to get out of it. Not everyone is looking for the same stuff when they buy a TV.

Some people want it exclusively for TV and watching Movies, some people are avid gamers who want a gaming TV that can keep up with the current generation consoles. There's those who only watch sports and some people who just want a good TV in the house for when they have people over. Whatever your reasoning, there's a bunch of different factors to think about that will form the basis for your decision. So let's have a look at some of those factors right now.


Samsung's MU7000When we use the word resolution, what we're actually talking about is how much detail the screen is capable of displaying. You've most likely seen this detail represented in the form of figures. You can see them in the settings on YouTube videos and on TVs and computer monitors, the most common ones these days being 720p and 1080p.

These are the two HD resolutions that would classify as being High Definition. These numbers are referring to the size of the image and how much it is actually appearing on the screen. The higher the number, the better the picture. Back when TVs first started being sold, the resolution would have sat at about 240p so they've come a long way since then and modern video capturing technology has come a long way itself.

The best cameras available to film and TV production companies these days are capable of picking up an incredible amount of detail and in order for you to experience as much of this detail as possible, you need to have a TV with the resolution capabilities necessary to convey it. The same applies to video games. These days, the graphics in video games are pretty much on par with CGI animated films and a TV with good resolution is the optimal way to play them. 4K UHD is a step above 1080p and that's pretty much the best you can get these days, but it's not necessary if you don't want to spend too much. If detail is important to you, we'd recommend 1080p.

High Dynamic Range

HDRHigh Dynamic Range, or HDR as it's more commonly referred to, is a relatively new technology that has become increasingly popular in the best 40inch TVs.

It's not something that you'll find in every TV but once you've watched HDR content you'll realize how much of an improvement it is over the norm. What the technology actually does is increase the range of brightness that the screen is capable of displaying.

Now, this doesn't necessarily mean that the screen is going to be abnormally bright, but actually that no matter how bright it gets, the detail won't be affected. And on the other end of the scale, no matter how dark it gets, you'll still be able to see a lot of the smaller details there too.

You've probably noticed on non-HDR TVs how murky and pixelated the screen tends to get when it's a particularly dark scene that you're watching. HDR is a solution to that. Much like the issue of high resolution, this is especially important these days because of how lifelike and detailed modern movies and TV shows are. And in the case of video games, it's pretty significant too. Video Game developers are taking full advantage of modern technology to put together some expansive games with very rich, full environments for you to explore. If you don't want to miss out on all the detail that's packed into movies, games and TV shows today then you should pick a TV with HDR to watch HDR content.

Motion Rate

Now, this might not be a term that you've heard before but believe us, it's an extremely important factor when it comes to televisions. What we refer to with Motion Rate, is the response time of the images as they appear on the screen. As the name suggests, this affects any kind of motion that occurs on your television. The higher the Motion Rate, the more clear and fluid the moving images. It's at its most noticeable when things are fast-paced, so during a high-octane action movie where there are car chases and fight scenes. If you have a Motion Rate of 60 for example, something like a high-speed car chase will probably get somewhat blurry.

Motion Blur can be very irritating and oftentimes it will ruin the experience. Even if you've got a TV that has great picture quality, a low Motion Rate will make everything look ugly and rough. And this one probably applies even more to video games than it does to movies because it's pretty rare that you'll find a subdued video game. There is some that have less action of course but for the most part, it's a lot of shooting and adventuring. With graphics as good as they are these days, low Motion Rate will destroy the imagery in a video game. Like we said, Motion Rate 60 isn't great but it's probably sufficient. We would, however, recommend that you look for a TV that has Motion Rate 120. The highest that you can get on a TV right now is Motion Rate 240 but that's not necessary unless you're willing to shell out extra for it. 120 should be just fine.

Smart Compatibility

Much like smartphones have pretty much taken over the cellphone market completely, it won't be long now before Smart TVs become the norm for TV users. You won't find many of the best LED Televisions being produced right now that don't have smart feature compatibility. It's very useful to be connected, we'd go as far as to say that it's almost essential. Smart TV offers you endless possibilities in this regard. The way that we consume media has changed these days. Set-top boxes are still a thing of course and there's plenty of people who still watch on the regular TV stations, but streaming is just as big, if not bigger than this traditional route. We get a lot of our movies and shows on Netflix, Hulu, Amazon Fire, Amazon Prime, and even YouTube is a place where you can rent a lot of movies now.

Smart TVAll of these services started on PC, but once Smart TVs arrived on the market, this was one of the features that were there from the start. You are almost guaranteed to have at least a couple of these services downloaded onto a Smart TV when you purchase it and any of the others will be available on the app store, usually free of charge.

And speaking of the app store, scrolling through that is a lot like scrolling through the play store on your phone. There are all kinds of useful stuff up there that you probably know nothing about. There are games, there are online shops, apps that offer tutorials on various things like exercise and cooking. And of course, there are a lot more streaming services to stream content than people realize. Many networks and productions companies have their own and there are specific ones for sports and news too. So this is something that we highly recommend. You'll end up getting a Smart TV at some point, might as well join the club right now!

Which 40-Inch LED TV is Right For You?

Weve said it already, probably a couple of times now, but I cant understate the importance of this: The decision is yours. You have your own specific desires and tastes and the right TV for you is not going to be the same as it is for others. So with all of the factors we discussed in mind, what you should do now is go back through them and decide which ones are absolutely essential for your TV and which ones you probably dont need. By doing this you can start eliminating some of the choices from the list of products and eventually narrow it down to just one. Theres definitely a TV out there for you, and youll be able to find out which one with a little bit of thought.

Who Makes the Best 40 Inch LED TV?

We believe that the brand who makes the best 40 Inch LED TV is Samsung. As you can see, 7 out of the 8 products that appear on our list come from Samsung and thats with good reason. They know what goes into a good TV and how to best use the technology thats available.

What are the Dimensions of a 40 Inch LED TV?

The dimensions of a 40 Inch TV (in W x H x D) will generally be about 36 x 24 x 9.

How Many Watts Does a 40 Inch LED TV Use?

This will vary a little bit from product to product, but you can expect an LED TV of 40 inches to use 31 Watts of energy.

How Far to Sit From a 40 Inch LED TV?

The recommended viewing distance is a bit different depending on the resolution but for a 1080p LED TV, you should sit no less than 5 feet from the TV. And for the optimal viewing experience, no more than 9 feet.

Expert Tip:

Many HDR TVs will come with an extra setting known as HDR+. This sounds like an improvement, but its actually something that you should probably avoid. All that it actually does is crank up the backlight to give the illusion that the colors are more vibrant than they actually are. In doing this, you will actually lose an awful lot of the detail in an excessively bright image.

4K resolution is relatively new when it comes to televisions, but the vast majority of smartphones are already capable of shooting 4K UHD footage and have been for several years now. See these amazing 4K televisions we have reviewed.
