Should you buy a big 75-inch or 85-inch 4K TV on Black Friday?

We've given our expert view on all of LG and Samsung's big-screen 4K TVs, so you know which are worth buying

It's not just smaller TVs that get discounts on Black Friday, mammoth 70, 75, 85-inch and even bigger TVs get price drops, too.

These TVs are massive - some are almost two metres wide and would take up an entire wall of rooms. But as people are increasingly looking for a cinema experience at home, these goliath TVs are getting more popular.

The size of these behemoths means they are still a relatively niche products though. Most of us just don't have a big enough room to accommodate one. But as prices have come down in recent years, what was previously an expensive, impractical purchase is within more people's reach.

We test hundreds of 4K TVs each year, so if you're looking at making purchase on Black Friday, odds are, we've got a review of it. Make sure it's a model worth buying - see our TV reviews

Our approach to big-screen TVs

By big-screen we mean anything bigger than 65 inches (not that 65 inches isn't big). We don't test many of these because they are simply too big for most people to really consider. We do understand that some people want to know what we think of these TVs though, which is why we write informed non-tested product reviews based on the technology in the TV and our years of experience testing them.

We also know that TVs from the same range tend to score within a few percentage points of each other and, because we've usually tested all the smaller models in a given range, we have an excellent indication of how good the bigger screen TVs would do if we tested them.

Should you consider a big-screen TV on Black Friday?

Budget is one thing, but the main thing you need to consider before you buy a wall-sized TV is whether your living room is big enough for it.

If you end up sitting too close to any TV it won't be as satisfying to watch. You don't want to crane your neck to take in the whole screen or need to move your head around to take in every inch of the display.

Sitting too close to an 85-inch TV will feel like sitting on the front row of an IMAX cinema. You're going to miss out on things happening at the edge of the screen because you can't take it all in.

How far away should you sit from your TV?

  • 70-inch: 14 feet
  • 75-inch: 15 feet
  • 85-inch: 16 feet

As you can see, you need a pretty big room to really see the benefit of such a huge screen TV.

Big-screen TVs from LG


LG releases more TVs than any other manufacturer, closely followed by Samsung. Each one of LG's TV ranges for 2021 has at least one big-screen option.


The LG G1, C1, B1 and A1 ranges all have a 77-inch option and there's even an 83-inch OLED83C14LA. Manufacturing costs are still high on OLEDs, particularly ones with such huge screens, and they are some of the most expensive TVs you can buy.

Expectations are always high with OLEDs and the sorts of prices these TVs command means expectations are higher than usual. Even the most basic A1 OLED costs £2,499 and the 77-inch top of the range G1 costs £3,999.

You can get our expert view on all these TVs and read our verdicts based on the quality of smaller models in their ranges.

LG NanoCell TVs

Below the OLEDs comes NanoCell TVs. These are backlit and use liquid crystals, just like LCD models, but have an extra nanocell layer to create more natural colours.

Screens go up to 86 inches with some ranges, but 75-inch is the most common screen size once you get above 65 inches. They aren't as expensive as OLEDs, but they still cost plenty.

The quality of NanoCell TVs has been more suspect in 2021 than it has in recent years, so our recommendation of the bigger models isn't such a sure thing.

Read what we thought of the LG NanoCell TVs based on our expertise and the reviews of the smaller models in each range.

We're not done with LG yet. At the bottom of its 2021 line-up we have the LCD TVs. These are the most basic in terms of specs. They lack advanced HDR formats and don't have high-powered processors that help with upscaling.

All that means they are cheaper, but with the quality of NanoCell ranges being a bit all over the place, we did find some solid LCD sets that we recommended.

That's a good sign for these colossal sets, and you can see what we thought of them based on how the smaller models fared in our lab tests.

Big-screen TVs from Samsung

Samsung QE85QN85AATXXU 4K TV

Samsung's TV range of 2021 models isn't quite as big as LG's, but there are still plenty of massive TVs to choose from. Neo QLEDs are at the top, then QLEDs make up the mid-range and LCD TVs are the entry-level and cheapest ranges.

Samsung Neo QLED TVs

2021 was the first time we saw Neo QLED TVs. They have quantum dots in the display, like the cheaper standard QLEDs, but the backlight changed. The LEDs in these TVs are far smaller, which means there's more of them. More LEDs generally gives a TV more control over how the screen is lit, which can help contrast.

These are the very top of Samsung's range and have prices to match, which are only increased by having such enormous screens. They also have every piece of TV tech going, including advanced HDR formats (HDR10+). High refresh rate screens and enhanced gaming software make the most of the latest games consoles, and more.

As with LG's OLEDs, these TVs should be incredible. So see what we thought of them based on our years of experience testing Samsung TVs and the quality of smaller models in each range.

Samsung QLED TVs

QLED without the Neo should still be a match for the best TVs from rival brands. Samsung has put its faith in these TVs to rival OLEDs for several years, and it's still one of the biggest TV brands on Earth. It's doing something right.

The quantum dots in these TVs work in tandem with the liquid crystals you usually find in LCD TVs to produce more vibrant colours.

The QLED ranges bridge the gap between high-end and mid-range, with pricier ones benefitting from similar gaming technology as the Neo QLEDs, while the cheaper ranges miss out.

Read our verdicts on each of the big-screen models from the QLED ranges based on how much we liked the smaller, lab-tested models in each range.


As ever, LCD TVs make up the bottom of Samsung's 2021 line-up. What's good about Samsung's more basic TVs is that they all have HDR10+, an advanced format that adjusts contrast for each scene.

Other than that you'll find these ranges to be fairly basic. Some don't have PVRs for recording shows onto a USB hard drive, while others lack voice control. None of those are essential though and won't make any difference to how good a TV looks and sounds.

Find out what we thought of all the big-screen sets in Samsung's cheapest 2021 ranges based on how well the smaller TVs we tested in our labs fared.
