Every TV screen is composed of numerous pixels, which are tiny squares that can display a specific color. Because each pixel is so small, you normally won't notice each one unless you are very close to your TV.

Those are the basics of TV resolutions. If you'd like to learn more about choosing a TV, you can read our TV Buying Guide. Happy shopping!

If you have a 4K TV, you may notice that most movies and TV shows are not available in 4K. However, this will likely change over the next few years. Netflix and Hulu offer some 4K content, and they will probably offer even more in the near future. For physical media, the main 4K option is Ultra HD Blu-ray, which requires an Ultra HD Blu-ray player.

Over the years we’ve seen other researchers attempt to create something like this before where bumps coinciding with on-screen buttons temporarily form on touchscreen panels providing tactile feedback to fingers, but the hardware has always been bulky making real-world applications a challenge on devices that are already made as thin as can be to satisfy consumer demands for pocketability.

The first plasma screen television has come quite a long way. However, the reason for the invention was not simply to provide men with amazing sports viewing.

Before we talk about the different resolutions, it’s important to put things into perspective. All TVs sold today are high definition (HD) or better, which means they have a fairly high resolution. For this reason, you shouldn't worry too much about finding the TV with the highest resolution. Instead, you should choose a TV that fits your needs and budget.

Versatility is what led smartphones to abandon tiny built-in keyboards for all touchscreen interfaces, as apps can take better advantage of screen real estate with tappable buttons and keyboards that are only temporarily on screen as needed. But as distracted drivers with touchscreen-only dashboards will tell you, physical buttons can still be a good thing as they provide tactile feedback to fingers—making them easy to find without looking.

If you’re shopping for a new TV, you may have seen terms like 4K, 1080p, and 720p. These terms refer to the resolution, or how much detail the screen can display. We’re going to give you a brief overview of common TV resolutions, and also show you how to find content that will look good on your TV.

The FIG researchers have succeeded in creating embedded electroosmotic pumps (EEOPs)—capable of moving liquids by applying electrical fields instead of using moving parts—that measure just 1.5 millimeters thick. They can be paired with an equally thin liquid reservoir beneath them, and a flexible surface structure on top, to almost instantaneously create pop-up buttons (the process takes about a second) measuring almost five millimeters in height with enough pressure and rigidity to make them feel solid when pressed.

Many cable TV channels have both HD and SD versions. Whenever possible, you should watch the HD version to get the best quality on your TV.

Researchers from Carnegie Mellon University’s Future Interfaces Group (FIG) are taking another shot at solving these issues with a technology they’re calling Flat Panel Haptics, as detailed in a new paper submitted to the ACM CHI Conference on Human Factors in Computing Systems which is currently taking place in Hamburg, Germany.

If you want to buy physical media, you can choose between DVD or Blu-ray format. Blu-ray is an HD format, so it will look much better than DVDs. However, Blu-ray discs cost more and require a Blu-ray player.

Keep in mind that HD content will still look great on a 4K TV, and you may not notice any loss of detail. Most 4K TVs also have an upscaling feature that can smooth out HD content and make it look closer to 4K.

The graphic below shows a visual comparison of each format, based on the number of pixels. As you can see, 4K has a much higher resolution than the other formats. However, depending on the size of the TV and your viewing distance, it may not look noticeably better. To learn more about whether 4K is worth the upgrade, read this article.

The literal flexibility of OLED screen technology has allowed us to create everything from tablets that fold in half, to TVs that disappear into furniture. But researchers from Carnegie Mellon University are leveraging the flexibility of OLED panels in another way, and have created touchscreen devices your fingers can actually feel.

Realistic vibrations, such as those generated by Apple’s Taptic engine, might make on-screen buttons feel real after you’ve pressed them, but that doesn’t solve the problem of your fingers being able to find those virtual buttons through touch alone. It’s why even touchscreen laptops still come with full QWERTY keyboards. Something as simple as typing can still be done much faster when relying on our sense of touch.

The more pixels the screen has, the higher its resolution. A higher resolution will allow the TV to display more detail, which means movies and TV shows will look better.

Today, the touch screen technology, or even the screen with the ability to introduce information by touch, will surprise no one.

A TV will only look as good as the media you play on it. Luckily, most streaming services like Netflix and Hulu are keeping up with current TV resolutions, so most movies and shows will look great unless you have a slow Internet connection.

OLED panels aren’t quite flexible enough to allow for structures that large to pop up. However, when layered atop the new embedded electroosmotic pumps, enough of a bump can still be formed to let a user’s fingers differentiate between the on-screen keyboard’s keys. There are still some limitations to the technology that may hinder adoption, including the fact that the shape and size of the pop-up buttons are pre-determined. But eventually, if they’re made as small as the actual pixels on an OLED display, any size and shape of tactile button could be generated on-demand, and gaming on a touchscreen will no longer be as frustrating as it is today.
