Should you choose LG, Samsung or Sony for the best cheap 4K TV?

Some of 2021's cheapest 4K TVs compared, plus see what you get if you pay more
Sony KD-55X80J 4K LCD TV

We're big fans of not spending more money than you have to. So as well as putting plenty of high-end 2021 OLED and QLED TVs through our independent lab tests, we also test the sets at the more affordable end of the spectrum.

These 4K LCD TVs are available for a third of the price of the top-end sets, so let's see what features you'll be missing out on if you choose a cheaper TV in 2021, and whether your money is best spent on an LG, Samsung or Sony TV.

The ranges we'll be looking at are:

  • LG UP7700 series
  • Samsung AU8000 series
  • Sony X80J series

Check out our pick of the best TV deals we found for August.

How the three TV ranges compare at a glance

The X80J is Sony's cheapest range. The LG UP7700 and Samsung AU8000 aren't quite these brands' cheapest - LG has the UP7500 range, and Samsung has the AU7100 range, but in terms of spec these are similar to the ones we cover here. We will test these even cheaper ranges in an upcoming batch but, as you can see from our table, below, the TVs from the LG UP7700 and Samsung AU8000 ranges are cheaper than Sony's.

Cheap TVs: LG vs Samsung vs Sony explained

Handily, there are clear differences between the brands that go some way to explaining the difference in price.

LG's range is the most basic of the three, with only two HDMI inputs and one USB port.

The more telling factor is HDR, though:

  • LG has HDR10 and HLG - these are basic formats with static contrast adjustment
  • The Samsung and Sony models have an advanced format - HDR10+ or Dolby Vision.

Advanced formats can adjust contrast to suit each scene, and HDR10+ can even react to the light in your room. This means the HDR picture should be better, as less detail is lost in boosted scenes that are too dark or bright. Advanced formats don't always equate to a better HDR picture, but they can help.

Samsung's cheaper ranges haven't had PVRs for some time, so it's no surprise to see it absent from the AU8000 ranges. If you like to record TV onto a USB hard drive, then you'd be better off with the LG or Sony.

Do any features set these TVs apart?

LG UP7700

LG 43UP77006LB 4K TV

Most of LG's TVs have the Magic remote, which is one of the best of any brand. As well as being ergonomic, with intuitively positioned and well labelled buttons, there's a motion-controlled pointer that makes it easier to select things on screen.

Film-maker mode was added to appease big-time directors who weren't happy with all the extra processing that TVs added to their masterpieces. Film-maker mode strips away the motion-smoothing that so offended the likes of Christopher Nolan and Paul Thomas Anderson, so the film is shown as the director intended.

LG's UP7700 is the cheapest range of the bunch, so it has a point to prove. Read our independent reviews to see if the most basic range is actually our favourite:

Samsung AU8000

You get Film-maker mode on the AU8000s, too, as well as some neat features to help the TVs to blend in with your decor.

Ambient Mode can display works of art on the screen when you're not watching, or it can mimic the pattern on the wall behind it.

Samsung TVs have the most comprehensive accessibility features, too, including a feature that increases the size of sign language interpreters as well as subtitles.

Samsung is the middle of the pack in terms of price and does have HDR10+. But it doesn't have a PVR and you can get a Samsung QLED TV for a few hundred more, so should you choose an AU8000?

Sony X80J

Dolby Atmos sound processing is designed to send audio over your head for an experience closer to surround sound. This is something TVs have struggled with, largely because they can't surround you with speakers, but audio processing can simulate the effect.

The tech is hit and miss, but Sony is proud of the audio on its TVs, and if the X80J can create a 360-degree soundscape with the help of Dolby Atmos, it would be a fantastic result.

It uses Google TV, which means Google Chromecast is built in so you can easily stream content from your phone onto the TV screen.

Unfortunately, Sony's TVs are missing UK catch-up apps for now.

Sony's TVs are often more expensive than their rivals, and the X80Js are particularly costly. They need to pull out all the stops to justify those prices. Read our reviews to see if they manage it.

What do you get if you pay more?

  • Guaranteed advanced HDR: Yoou'll get either HDR10+ or Dolby Vision as standard, and you might get Dolby Vision IQ, too. It can adapt contrast based on ambient light in your room, just like HDR10+ can.
  • Higher screen refresh rates: High-end TVs often have 120Hz screens, which means the screen can display 120 frames per second. This is great for gaming and making some content look smoother.
  • Better gaming features:120Hz helps, but there are more features gamers should look for. VRR (variable refresh rate) can compensate for dropped frames, which would otherwise make gameplay look like it's stuttering.
  • FreeSync and G-Sync: We're not done with the gaming features yet. These two pieces of software were made by graphics card manufacturers to make games look and play better on TVs.
  • OLED and QLED screens:OLEDs are known for exceptional contrast, and QLEDs - particularly the latest Neo QLED tech - are bright and colourful.
  • Ways to make the TV discreet: Spending more usually means better cable management features and thinner bezels so your TV stands out less when you're not watching.
  • Better quality: It's not always the case, but quality tends to follow price with TVs. We still find cheaper models that excel, but high-end sets tend to look and sound better.
