4K vs 1080p: Which resolution is right for you?

Resolution is a key part of any new TV purchase, but it may not be as cut and dry as you expect.

Upgrading to a new TV is always exciting, but potentially daunting given so many sizes, manufacturers, and specifications to choose from. Beyond that, most modern TVs are equipped with some sort of smart platform, such as Roku or Android TV. Today we want to focus on a specific issue, the choice of 4K vs 1080p when it comes to resolution.

What is 1080p?

In simple terms, 1080p indicates a display resolution with 1,080 vertical pixels. This is matched by 1,920 horizontal pixels, and multiplied together, you get a little over 2 million pixels in total. The “p” in 1080p doesn’t stand for pixels, however. Instead it indicates progressive scanning, meaning that an entire image is transmitted at once instead of through a series of interlaced scans. A 1080i (interlaced) spec technically exists, but it’s visually inferior and no one really markets it anymore.

What is 4K?

If you thought 2 million pixels was plenty, a 4K TV packs 3,840 horizontal pixels multiplied by 2,160 vertical pixels, for a sum just under 8.3 million. The “K” in 4K isn’t a technical reference like the p in 1080p ― rather, it refers to thousands. Specifically it relates to the (nearly) 4,000 horizontal pixels.

4K vs 1080p: The biggest differences

Some of the differences in 4K vs 1080p TVs are obvious, but others aren’t, and it’s worth breaking things down to better understand.

Detail and sharpness

With nearly four times as many pixels, you can see significantly more detail on a 4K TV, and video should appear sharper overall. You do need a screen large enough to notice this difference — generally something 50 inches or more.

Colors

Extra pixels allow 4K TVs to achieve more dynamic colors than 1080p sets, including deeper shadows. Technologies like OLED and HDR have a greater impact in this regard, but resolution does matter.

Content

For now, 1080p TVs still have the edge in terms of content. Sure, plenty of movies, games, and TV shows are in 4K, but not everything has made the leap yet — so even if you have a 4K TV, you may end up watching upscaled 1080p. The latest PCs and consoles sometimes have trouble sustaining 4K if they’re running high-end 3D graphics.

Availability and cost

Well into 2022, 4K TVs are de facto rather than the exception. A recent search we did at Best Buy revealed 31 1080p TVs compared with over 430 4K options.

The manufacturing costs of 4K panels have dropped significantly in recent years, and the savings are being passed down, inflation and supply chain issues notwithstanding. An excellent 4K TV can run as low as $300 from manufacturers like TCL, while still having a platform like Roku, Fire TV, or Android TV built-in. 1080p sets can be even cheaper, but tend not to be produced much in sizes over 40 inches.

Why choose 1080p?

Above all, 1080p sets are incredibly cheap, as we mentioned a moment ago. You can buy a 1080p TV, a game console, and even a few games for less than what some high-end 4K TVs will cost you.

There’s a good bit of overlap between 1080p and 4K features, too. You’ll have access to most of the same smart TV apps, and you can plug your favorite streaming devices into either kind of TV.

If you mostly watch livestreams or broadcast TV, there’s not much point to 4K, since the majority of what you’re seeing will be in 1080p or even smaller resolutions. If you specifically want a TV sized 40 inches or smaller, 4K probably won’t be an option.

Why choose 4K?

4K content is, increasingly, standard. While most services still offer 1080p or lower, a necessity for the mobile market, the push is underway to make everything available in 4K for big-screen viewers, even YouTube videos. Consoles like the PS5 and Xbox Series X can handle the resolution, as can dedicated streaming devices like the Chromecast with Google TV.

4K content is, increasingly, standard.

TV makers also tend to save their most advanced features for 4K sets, such as HDR and Dolby Atmos sound. The assumption is that anyone buying a 1080p TV at this point is probably more budget-minded, so adding features to them is only going to hurt sales or profit margins.

The price gap between 4K and 1080p is narrowing anyway, and if you’re willing to spend extra, better 4K sets can blow 1080p TVs out of the water. It’s only 8K sets that are ridiculously overpriced, since the technology is on the bleeding edge with very little native content to watch.

Now that we’ve gone through the differences and arguments for both standards, the real question is where to put your money down personally.

We’d have to know more about your situation to give a concrete recommendation, but that said, people with disposable budgets of $300 or more shouldn’t even think twice about 4K. Given how scarce native 8K video is, even rich shoppers may be better off buying a 4K OLED set and waiting for 8K support to improve, by which point the hardware will have evolved as well.

If budget is an issue at all, you can feel comfortable sticking with 1080p for the next few years. Heck, if you are rolling in cash, 1080p TVs remain a great choice for bedrooms and guest rooms, since you’re probably after a smaller size in the first place, and cinephiles can make their way to the living room.
