Editor's note: March 2024

This best 40, 42 and 43-inch TV guide could be shaken up soon as the new TVs unveiled at CES 2024 hit the market. This is the biggest tech event of the year where all the major TV makers reveal their latest devices. 

We'll update this guide as soon as we've had chance to test out some of the latest 40, 42 and 43-inch TVs ourselves. We're particularly excited to test the LG C4, which could replace the LG C3 in our list below.

Matt Bolton, Managing Editor – Entertainment

The best 40- to 43-inch TVs are not to be underestimated. They might not have the gargantuan screen heft of larger TVs, but you can get some great-looking sets here that won't take over your room – and they’re exceptionally affordable at this size.

And don’t be fooled by their small form factor. Many of the best 40, 42 and 43-inch TVs don’t compromise on functionality compared to the best 65-inch TVs or the best 75-inch TVs even – they can give you 4K resolution and HDR (high dynamic range) – for ultra-crisp visuals and bright colors. Plus, just like their bigger siblings, you’ll get the same smart TV interfaces with streaming services built in for all your regular Netflix and Disney Plus binges. 

You’ll even find a couple of the best gaming TVs below. If you want to plug in a PlayStation 5 or Xbox Series X, LG's 43-inch C3 comes with HDMI 2.1 functionality for variable refresh rate and gaming in 4K at 120fps on all of its ports – it's basically a flagship TV in a smaller frame.

You might notice that there aren't very many of the best OLED TVs in the list below. That's because smaller OLED panels are still difficult for manufacturers to make without lots of waste, and that means they're still expensive to create. LG appears to have cracked the problem with its very impressive 42-inch C3, but you'll find that the bulk of the best TVs at this size don't yet use OLED.

We test these TVs just like everything else we review, looking at brightness, color accuracy and overall picture performance, as well as sound quality. We'll balance these with their price and features, to find the best 40- to 43-inch TVs to recommend.

The best 42-inch TV if you love movies and gaming

Specifications

Screen size: 42 inches
Resolution: 3840 x 2160
Panel type: OLED
Smart TV: webOS
Dimensions: 932 x 540 x 41.1mm

Reasons to buy

+
Great overall picture quality
+
Improved smart TV interface
+
Extensive gaming features

Reasons to avoid

-
Average built-in audio performance
-
One of the more expensive options

The LG C3 simply does it all. It's wonderful for movies thanks to its OLED screen, it's packed with every gaming feature hardcore gamers could want, and its smart TV platform has loads of great features, as well as comprehensive streaming support.

Because each individual pixel of an OLED TV generates its own light, you get perfect precision in scenes that contrast light and dark, with true black right next to bright lights. You also get very impressive nuance in dark scenes, bringing out more detail in these moment than LED TVs can manage.

This TV delivers excellent picture quality, with impressive levels of brightness, contrast and definition. It takes advantage of LG’s Alpha9 Gen6 chip, which is used for picture processing and HDR-improving features, like Expression Enhancer and OLED Dynamic Tone Mapping Pro. What this means is that your images look clearer, better and brighter. That's why we think it's a wonderful choice for movie lovers. And OLED is famously less bright than LED TVs in larger sets, but in 42-inch models, they're much more on the same level, so you don't get a real disadvantage there.

Four HDMI 2.1 inputs with support for 4K 120Hz, VRR, ALLM, along with FreeSync Premium Pro and Nvidia G-Sync, make it a dream for console and PC gamers alike.

The only notable downside is that buyers in the US should be aware that it lacks the built-in ATSC 3.0 digital TV tuner found in LG’s step-up G3 TV – but that isn't available in a 42-inch size.

Amazon Omni QLED with Top Gun Maverick on screen

(Image credit: Future)
The best cheap 43-inch TV

Specifications

Screen Size: 43 inches
Resolution: 4K
Panel type: QLED
Smart TV: Fire TV
Dimensions: 956 x 574 x 84 mm

Reasons to buy

+
Colorful picture with great detail 
+
Solid gaming performance 
+
Outstanding value

Reasons to avoid

-
Slightly stuttery smart TV software
-
Middling black levels
-
Not great sound

The Amazon Fire TV Omni QLED is the definition of value for money. Great picture quality and gaming performance make this a TV with a lot of bank for its buck. Already at a cheap price on release, the Amazon Omni often finds itself with heavy discounts, particularly during Black Friday (with prices as low as $299/£299 for the 43-inch).

The picture quality of the Omni QLED was a real surprise when we viewed it. Yes, it's not the best picture by any stretch, because its black levels aren't particularly strong (and this 43-inch version lacks the local dimming of the larger models in this range), but the detail in movies, particularly in 4K HDR, is impressive. Colors pop from the screen and there's a certain natural quality to the image that can be lost in budget TVs.

Gaming performance was another plus point for the Omni QLED. It did a great job of handling graphically intense moments, with smooth motion processing and minimal delay thanks to its low 10ms input lag time. The picture quality delivered was crisp as well, thanks to Dolby Vision gaming support. However, it sadly doesn't have 4K 120Hz support, but this is not something you get in TVs at this price range anyway.

There are plenty of TVs that top the Amazon Fire TV Omni QLED in every area, especially when it comes to sound and design, but combining what it does have in to one set at this price, the Omni QLED is unbeatable value.

Smart TV: Tizen
Dimensions: 960.8 x 558.9 x 26.9 mm

Not the best smart TV layout

The Samsung QN90C is available in a wide range of sizes from 43 through to 85-inches, with the lower end bringing it to our list of the best smaller TVs. Its solid reflection handling and brightness makes it a good choice for lots of purposes and lots of rooms. We find that's often what most people want from a smaller TV: versatility. 

You don't get the same high level of brightness that we measured from the larger sizes of this TV when we measured those, but you do get far brighter pictures than most small TV thanks to the mini-LED backlight, which means beautiful HDR and better visibility in bright rooms. We picked out the anti-glare screen as a real highlight – along with the gaming support, which is great in the small model too. HDMI 2.1 support up to 4K 144Hz is perfect for new-gen consoles.

Samsung's image processing makes it look refined and impressive cinematic, and the eight speakers built into it means it'll sound far better than the competition here, and you may not need to add a soundbar for clear audio. All of this does mean its the most expensive option here, though.

Our biggest complaint is really the smart TV software layout, though – it's not as intuitive as some options.

Best 40-, 42- and 43-inch TV FAQ

Is a 40-inch TV big enough?

It's worth remembering that 40-inch screens, while once the pinnacle of high-end TV tech, are now considered a small size compared to many other TV displays.

Manufacturers can make bigger screens than ever before and, these days, 55-inch 4K TVs are standard, with 65-inch 4K TVs quickly growing in popularity. 

A 40-inch TV should come with 4K resolution, but you'll be able to see the benefits more clearly on a larger size. We find that a 40-inch TV is a pretty decent size for a single viewer not sitting too far away, but for a family or group of flatmates it's not ideal. 

To make sure if a 40-inch TV is right for you, measure the space you'd like to put it in and consider how much your budget can stretch. 

In this guide, we've also included several 42-inch and 43-inch TVs, which might give you a bit of extra screen space if the best 40-inch TVs seem a touch too small.

What about 42-inch TVs and 43-inch TVs?

For ease, we've included 40-inch TVs as well as the best 42-inch TVs and 43-inch TVs in this guide. 

Of course, many things affect the size and scale of a TV screen beyond simply the diagonal length of the panel, including the width of the bezel (the black strip around the screen's edges), built-in speakers, HDMI inputs and connections, as well as the depth of the casing (which often varies in different places). What this means is you may not notice the difference between a 40-inch TV and a 43-inch TV due to all of these factors. 

We've also seen increased production of 42-inch TVs in recent years, with TV brand LG bringing out 42-inch OLED TVs, like the LG OLED42C2 at the top of this guide. 

Many people find 42-inch and 43-inch TVs are perfect for smaller rooms, like studies, kitchens and any other space in your home where you don't need a huge, cinematic display. Even for smaller living rooms, 43-inch TVs are the perfect sweet spot.

How do I pick out a 40-inch, 42-inch or 43-inch TV?

Not sure how to choose what 40-inch, 42-inch or 43-inch TV is for you? While the options might feel overwhelming, it's worth considering what we think about when recommending TVs here on TechRadar.

Ultra HD vs Full HD: It's a common misconception that you can't see the difference between full HD and Ultra HD/4K on a screen smaller than 55 inches. You can. We recommend picking a TV with 4K Ultra-HD and HDR if you can find one. It makes a big difference. 

Operating system: 40-inch, 42-inch and 43-inch TVs didn't always come with a smart TV operating system in the past but they often do now. What you're looking for, ideally, is a well-maintained operating system like Roku TV, LG's webOS or Samsung's Tizen operating system. If you go with a TV that uses a proprietary operating system (basically an operating system exclusive to that one TV) you might have some serious issues down the road.

Inputs and outputs: Multiple HDMI ports are important if you have many devices to hook up to your TV but you may find less on a TV that's smaller than 43-inches. We recommend choosing a TV with more one HDMI port. You'll find yourself swapping cables far too often if you do.
