Best 50-inch TVs 2021: 4K TVs for every budget

Included in this guide:

Best 50-inch TV Buying Guide: Welcome to What Hi-Fi?'s round-up of the best 50-inch TVs you can buy in 2021.

There was a time when a 48-inch, 49-inch or 50-inch TV would have been considered huge – in 2021 it's now considered by many manufacturers (and some consumers) to be almost small and, as a result, unworthy of the latest tech. 

It was only in 2019 that the first Samsung QLED was released at this size, and it took until 2020 for the first OLED TVs at this size to appear (and, as you'll see below, very good they are too).

But what if a 50-inch screen is the maximum size TV that you want or are able to fit in your room? We've got good news. Not only can you now get a true flagship TV (one of those aforementioned 48-inch OLEDs), you're also in prime mainstream territory, where manufacturers and retailers sell the most models and where competition is at its fiercest. In other words, the best 48-inch, 49-inch and 50-inch TVs should deliver excellent value for money.

When it comes to picture technology, almost all models at this size are now 4K, and there's no need to look for a Full HD model, because these 4K TVs are already very affordable indeed. 

Features should be strong across the board, so expect streaming apps from Amazon, Disney+, Netflix, YouTube and more to come as a standard. You can expect HDR, too, at least in HDR10 form but often in the more advanced HLG, Dolby Vision and/or HDR10+, ensuring the best possible 4K pictures. 

And with the LG 2021 TVs, Samsung 2021 TVs and Sony 2021 TVs all announced and on their way, you can expect to see prices drop on some of our favourite TVs released last year - so it's a great time to pick up a bargain. Read on for our pick of the best 48, 49 and 50 inch TVs. 

How we choose the best 50 inch TVs

Here at What Hi-Fi? we review hundreds of products every year – and that includes plenty of TVs. So how do we come to our review verdicts? And why can you trust them?

We have state-of-the-art testing facilities in London and Bath, where our team of expert reviewers do all our testing. This gives us complete control over the testing process, ensuring consistency. 

All products are tested in comparison with rival products in the same price category, and all review verdicts are agreed upon by the team as a whole rather than an individual reviewer, again helping to ensure consistency and avoid any personal preference.

The What Hi-Fi? team has more than 100 years experience of reviewing, testing and writing about consumer electronics.

From all of our reviews, we choose the best products to feature in our Best Buys. That's why if you take the plunge and buy one of the products recommended below, or on any other Best Buy page, you can be assured you're getting a What Hi-Fi? approved product.

Best 48-inch TV

1. Sony KD-48A9

Sony’s first 48-inch OLED TV is superb.

Specifications
Screen size: 48in
Type: OLED
Backlight: not applicable
Resolution: 4K
HDR formats supported: HDR10, HLG, Dolby Vision
Operating system: Android TV 9
HDMI inputs: 4
ARC/eARC: eARC
Optical output: Yes
Dimensions (hwd, without stand): 62 x 107 x 5.8cm
Reasons to buy
+Striking picture+Bold sound+Solid app selection
Reasons to avoid
-Expensive-Lacks next-gen HDMI features

It's official: 48 is the new 50. Time was that you couldn't get an OLED TV under 55in, but then LG launched the world's first commercially available 48in OLED set. And now Sony has one of its own, too - and it's the best TV you can buy around this size.

Sony has embraced the smaller size, making the KD-48A9 (known as the XBR-48A9S in the US) as petite as possible thanks to its tiny bezels and low profile pedestal stand. It does have a rather large enclosure bolted onto the back (to house the speakers, processing hardware and connections), but you'll only notice if you look at the set side-on.

Sony's X1 Ultimate processor makes images suitably stunning, there's plenty of dark detail on show, and it serves up pretty much every streaming app you could hope for. Motion control is still industry-leading, and in terms of sharpness and detail, there's never been a better TV at this size. If you can afford it, this is a superb option, and certainly the best 48-inch TV that we've tested.

2. Sony KD-49XH9505

If you can't stretch to the OLED, this is the next best option.

Specifications
Type: LCD with direct LED backlighting
Screen size: 49-inch
Resolution: 4K
HDR support: HDR10, Dolby Vision, HLG
HDMI: 4
Dimensions (hwd, without stand): 62.9 x 109.3 x 6.9 cm
Reasons to buy
+Punchy, rich picture performance+Vastly improved sound+Snappy user experience
Reasons to avoid
-Same design as previous generation-Some backlight bloom

The Sony HX may look very similar to the previous generation but the performance has been improved across the bar.

Inside is the new X1 Ultimate chip, which aims to improve definition and contrast, and provides a faster experience around the Android TV interface. You get all the apps you'd expect, from Amazon Prime Video to Disney+ and Netflix, plus support for catch-up TV apps, AirPlay 2, Dolby Vision and HDR10.

As for the picture, expect rich, punchy colours, excellent handling of fast motion and good black detail. It looks great with high-quality Dolby Vision and HDR video, while gamers will be happy with the lower input lag and overall vibrancy. Sound quality has taken a big step forward, too, with an openness and dynamism that's rare in a TV of this size and price.

Better picture, better sound, this remains one of the best 49-inch TVs we've seen.

3. LG OLED48CX

The first 48-inch OLED of the 4K era – and it's an absolute stunner.

Specifications
Screen size: 48in (also available in 55in, 65in, 77in)
Type: OLED
Backlight: not applicable
Resolution: 4K
HDR formats supported: HDR10, HLG, Dolby Vision
Operating system: webOS
HDMI inputs: 4
ARC/eARC: eARC
Optical output: Yes
Dimensions (hwd, without stand): 62 x 107 x 4.7cm
Reasons to buy
+Flagship-level OLED performance+Dramatic but natural picture+Forward-looking feature set
Reasons to avoid
-Missing UK catch-up apps-Pricey for its size

The OLED48CX was the first 48-inch OLED TV that we reviewed – and we were, and remain, very impressed.

Picture quality is superb. The perfect blacks and near-perfect viewing angles combine with bright, punchy whites and vibrant but natural colours. LG's motion processing was a big step up in 2020 and its upscaling of 1080p and standard-def content remains among the best in the business.

On top of all that you get certified HDMI 2.1 sockets that support next-gen features such as eARC (Enhanced Audio Return Channel), HFR (High Frame Rate), ALLM (Auto Low Latency Mode), and all current formats of VRR (Variable Refresh Rate). All of these are useful if you're looking to upgrade to the PS5 or Xbox Series X.

All of the UK's catch-up apps, including BBC iPlayer, were missing from LG's smart platform when we reviewed the set but these should be added with an update.

4. Samsung UN50RU7100

This 50-inch Samsung TV is a great buy for those on a budget

Specifications
Screen size: 50-inch
Type: LCD
Backlight: Edge-lit
Resolution: 4K
HDR formats: HDR10
ARC/eARC: ARC
Optical output: Yes
Dimensions: 10.3 x 44.3 x 28.7 inches
Reasons to buy
+Good colors+Decent sound+Smarter than most
Reasons to avoid
-Bland design-Middling HDR performance-Basic remote control

The Samsung RU7100 is a budget 4K TV that balances its feature set and price perfectly for those looking for something not-too-pricey and not-too-cheap.

The RU7100 has three HDMI ports, including one with ARC support, two USB ports, an optical audio output for older surround sound systems, wireless connectivity and Bluetooth for connecting headphones.

Samsung's smart platform remains one of the best in the industry, from the refined home screen and menus to Samsung's excellent app selection, which includes Apple TV and Disney+.

All told, from its decent picture quality and sound, to the fantastic smart TV experience we’ve come to expect from Samsung sets, there’s plenty to love here, all without a hefty price tag.

5. Vizio V505-G9

A seriously affordable 50-inch 4K TV

Specifications
Screen size: 50-inch
Type: LED
Backlight: Full-array LED backlight
Resolution: 4K
HDR formats: HDR10, HLG, Dolby Vision
ARC/eARC: ARC
Optical output: Yes
Dimensions: 44.13 x 25.59 x 2.42 inches
Reasons to buy
+Decent picture quality+Good HDR format support+Built-in Google Chromecast
Reasons to avoid
-Basic port selection-Middling HDR performance-Quiet audio

With a price tag of less than $500, what the 50-inch Vizio V505-G9 offers in features and performance is quite appealing. There's Google Chromecast support, a good selection of locally installed apps and Vizio’s dedicated channel of free streamable content.

It does pretty well in the performance stakes for this level too, offering a decent 4K picture, broad HDR support and a relatively attractive design, making it one of the better cheap TVs you can buy.
