Here is where we'll mention that, in 2021, most TV channels still broadcast in 1080. This 43-inch Hisense set has 1080p resolution and built-in AndroidTV. For many shoppers, the sub-$300 price tag will far outweigh what this set sacrifices in pixels. As we mentioned before, the smaller your screen is, the less noticeable the benefits of Ultra-HD resolutions (like 4K and 8K) are at a given viewing distance.

With the voice-activated, Alexa-powered remote, you can switch between channels, search for movies by genre and even check the weather using this TV. Fire TV is a good choice if you've already built an Alexa-based smart home.

This model of Amazon's new Fire TV Omni Series measures 55 inches along the diagonal and has 4K resolution. Like many 4K models, this television will automatically upscale 1080i broadcast content to 4K. If image quality is of the utmost importance, the additional cost may be worth it. This TV also comes with a far-field microphone for true hands-free control. That means you can change the channel without talking to your Alexa remote.

The Amazon Fire TV Omni Series is on sale during Amazon's early Black Friday sale, so it's a great time to pick one up.

UHD 8K televisions have four times as many pixels as their 4K brethren, but whether you can perceive the difference in quality depends heavily on your viewing distance and the size of the screen. Samsung says this TV upscales all source material to 8K, though results may vary based on the content's native resolution.

Eventually, there will be 8K content available to watch, but for now, 8K resolution functions mostly as a very expensive future-proofing option.

With the voice-activated, Alexa-powered remote, you can switch between channels, search for movies by genre and even check the weather using this TV. Fire TV is a good choice if you've already built an Alexa-based smart home.

At just 32 inches, this budget-friendly Toshiba TV is suited for small spaces like bedrooms or offices. It runs Amazon's FireTV platform, so you can stream new shows from Hulu, Netflix and more without plugging in extra equipment. You'll trade a fair amount of resolution for the tiny price tag, though. This unit has a 720p display--that's technically high definition, but not the 1080p HD you'll find on many modern televisions.

One way to cut costs when shopping for a TV is to search for an LED option. The differences between LED TVs and newer, fancier models primarily register in their color and luminosity output. If you don't feel strongly about the accuracy and saturation of your TV's colors, you can save a bit of cash without sacrificing much by choosing a set like this 50-inch Samsung, now on sale for Black Friday.

If you're already used to a certain interface, switching can be tough, especially if you're not particularly tech savvy. Fans of the super-simple Roku platform should look for a TV – like this TCL model – with a built-in Roku system. (Plus, the picture quality of this 6-series model is stunning for the money.)

Smaller sets, like this Roku model from TCL, give you more wiggle room in terms of resolution, since each individual pixel covers less surface area. With a screen this small (32 inches), you don't need more than 1080p resolution: The benefits of 4K don't become obvious unless you're sitting very (and we mean very) close to the screen. Again, the ideal viewing distance for a 32-inch 1080p TV like this one is between 4 and 6.5 feet. It's currently on sale for $50 off during Walmart Deals for Days.

Once you get into the four-figure price bracket, like with this Samsung 4K Neo QLED, you access even more top-of-the-line features such as a built-in Alexa assistant and a premium piece of audio technology called object-tracking sound (OTS). With OTS, your television analyzes the action on screen and tries to replicate a surround-sound experience without any external speakers.

Similarly, Android users can keep all of their tech in the same universe with a television that has on-board AndroidTV.

For just $500, your options open up quite a bit. This highly reviewed 50-inch TCL set has QLED (quantum dot LED) technology, 4K resolution and Dolby Vision. All those features together improve the sharpness, brightness, color and contrast of an image.

A mid-size television, 55 to 65 inches along the diagonal, is large enough for many living rooms. The ideal viewing distance for a 55-inch 4K TV, such as this model, is between 4.5 and 7 feet. This brand new model, now $140 off during Amazon's early Black Friday sale, is proving popular.

If you just need more screen, this 86-inch LG should fill up your space. It has a 4K UHD resolution and works with Alexa and Google Assistant.

It is a very large television, so if that's your endgame, this is a well-reviewed option.

QLED TVs have a quantum-dot layer sandwiched between those LED lights and the LCD layer. This middle layer filters the light to produce more vibrant and accurate colors.

If you're looking to get the richest color out of your set, a QLED model, like this 55-inch TCL 6-Series, could be a good option.

Unlike LED and QLED TVs, OLED TVs don't have a backlight layer. Instead, each pixel is it's own teeny-tiny LED light that can independently change its luminosity and even turn off completely. Because each pixel functions independently, these TVs have elite image quality and the darkest shadows. OLED televisions also tend to be ultra thin -- this particular set measures just 1.8 inches thick.

The one issue with OLED TV sets is that, if you're planning on watching a lot of content with static elements (think scoreboards or omnipresent logos), you risk burn-in. It's uncommon with normal use, but still possible.
