4K Ultra HD

4K Ultra HD TVs

4K is the resolution nearly every TV sold today uses, and for most people it is the right one to buy. A 4K Ultra HD panel holds about four times the pixels of Full HD, which is what keeps a 65-inch screen looking sharp from eight feet away instead of soft. BrandsMart USA carries 4K sets at every price point.

Browse the full 4K range below, or come compare screens side by side in one of our Florida and Georgia showrooms before you commit to a size. Seeing two sets next to each other settles the size question faster than any spec sheet does.

Shop 4K TVs by Screen Size

40 to 49-inch 4K TVs. Bedrooms, kitchens and home offices, where you sit close enough for 4K detail to still show.
50 to 59-inch 4K TVs. Apartments, dens and smaller living rooms. This is where the jump from 1080p becomes obvious.
60 to 69-inch 4K TVs. The 65-inch class, the most popular size in the country and the safe pick for a typical living room.
70 to 79-inch 4K TVs. A 75-inch set for a wide room, or for anyone sitting ten feet back or more.
80-inch and larger 4K TVs. Home-theater scale. Measure the wall, the stand, and the doorways before you order.

If you would rather shop by panel technology, compare OLED TVs for dark-room contrast, LED and QLED TVs for peak brightness and the widest price range, or look at 8K TVs if you are buying a very large screen. Almost every 4K set on this page is also a smart TV with streaming apps already built in.

Shopping by brand works too. Compare Samsung 4K TVs for bright quantum-dot panels, LG 4K TVs for gaming features and webOS, or TCL 4K TVs for large screens at a lower price per inch. Sony, Vizio, and Hisense are all here as well. See the full brand lineup.

What does 4K Ultra HD mean?

4K Ultra HD means a screen resolution of 3840 by 2160 pixels, which is about four times the pixel count of Full HD. You will see it written as 4K, UHD, Ultra HD and 4K Ultra High Definition, and they all refer to the same thing. There is no practical difference between a TV labeled 4K and one labeled UHD.

What size 4K TV should I buy?

For a typical living room with seating eight to ten feet from the screen, a 65-inch set is the size most people end up happy with. Sit closer than eight feet and 55 inches is plenty; sit further back or want a theater feel and 75 inches makes sense. Start with 60 to 69-inch models and move up or down from there.

Is 4K worth it if most of what I watch is not in 4K?

Yes, for two reasons. Streaming services now carry most new movies and series in 4K, and sports coverage is slowly following. Everything else gets upscaled by the TV, and modern processors do that well enough that HD content generally looks better on a good 4K set than on an old 1080p one.

What is the difference between 4K and HDR?

They are separate things that often ship together. 4K describes how many pixels the screen has. HDR describes how bright, how dark and how colorful those pixels can get. A 4K set without good HDR performance can look flatter than a well-tuned HDR display, which is why brightness and contrast are worth comparing alongside resolution.

Do I need a new HDMI cable or a new streaming device for 4K?

For basic 4K you usually do not, but for 4K at 120Hz or full HDR bandwidth you want High Speed or Ultra High Speed HDMI cables. Your built-in apps will stream 4K without any extra hardware. If you prefer a different interface or want an older TV to keep up, our streaming devices handle 4K and HDR too.

Should I buy a 4K OLED or a 4K QLED?

It depends on the room. OLED controls light pixel by pixel, so it wins on black levels, contrast and off-angle viewing, which makes it the better choice for dim rooms and film. QLED is an LED-backlit set with a quantum-dot layer, and it gets brighter, which matters in a room with big windows. Compare OLED models against the LED and QLED range and let your lighting decide.

Are all 4K TVs smart TVs?

Effectively, yes. It is very hard to buy a new 4K TV without a built-in smart platform, so the real question is which platform you want to use every day. The interfaces, remotes, app stores and voice assistants differ quite a bit between brands.

Do 4K TVs use more electricity?

A little, mostly because 4K sets tend to be larger and brighter rather than because of the resolution itself. Many models carry an ENERGY STAR rating, and turning down the backlight from the store's demo setting cuts power draw noticeably while also making the picture look more natural at home.

Where can I compare 4K TVs in person near me?

BrandsMart USA has large showrooms across Florida and Georgia with 4K sets running side by side, which is the only reliable way to judge brightness, glare and size for your room. Find your nearest showroom and bring the measurements of your wall or media stand.

Do I need a 120Hz TV?

Only if you game on a current console or PC. A 120Hz panel paired with HDMI 2.1 lets a PlayStation 5, Xbox Series X or gaming PC output 120 frames per second, which makes fast motion noticeably smoother and cuts input lag. For movies, streaming and broadcast television it does very little, because almost none of that content is delivered above 60 frames per second. If nobody in the house games seriously, put the money into panel brightness or a larger screen instead.

What financing options are available on 4K TVs?

Three, and they are worth knowing apart. The BrandsMart USA credit card offers 0% promotional financing on qualifying purchases, and TVs are one of the categories where the longer terms tend to show up. Katapult is lease-to-own with no credit needed, and checking your buying power does not affect your credit score. Klarna splits the cost into interest-free installments and gives a decision in seconds. Current terms are listed on our financing page, and the team in store can tell you what is running.

What 4K Actually Gets You

1. Resolution matters more as the screen grows

Pixel count only pays off when the pixels are big enough to notice. On a 40-inch screen at normal seating distance, 4K and 1080p look close. At 65 inches and up, a 1080p picture starts to look soft while a 4K one holds detail in faces, jerseys and text. The bigger the screen and the closer you sit, the more the extra resolution is doing.

2. Upscaling handles everything that is not 4K

Most of what you watch is not native 4K. Cable, broadcast, older streaming libraries and DVDs are all lower resolution, and the TV's processor stretches them to fill the panel. Good upscaling adds sharpness without adding noise or halos around edges, and it is one of the real differences between a budget set and a step-up model. If you watch a lot of live sports or cable, judge a TV on upscaled content in the store, not on the demo reel.

3. HDR is the upgrade you will see most

High dynamic range widens the gap between the brightest and darkest parts of the picture, and it usually makes more visible difference than resolution alone. HDR10 is the baseline every 4K set supports. HDR10+ and Dolby Vision add scene-by-scene instructions, and HLG shows up on broadcast content. Brands split between the two premium formats, so check which one your favorite services use before you decide.

4. Gaming features are worth checking now

If a console or gaming PC is connected, look for HDMI 2.1 inputs, a 120Hz panel, variable refresh rate and auto low latency mode. Those four together are what keep fast motion clean and input lag low. Count the HDMI
2.1 ports as well, since some sets only give you one or two.

5. 4K is a baseline, not a premium feature

A decade ago 4K was the reason to spend more. Today it is standard on almost everything above the smallest screen sizes, so the price differences between 4K sets come from brightness, local dimming, processing, sound and build quality instead. Compare those, and treat the 4K badge as a
given.

Sound and Setup

Flat panels leave very little room for speakers, so even an excellent 4K picture usually arrives with thin audio. A soundbar is the single biggest improvement most people can make after the TV itself,
especially for dialogue. If the set is going on the wall, check the VESA pattern against our TV wall mounts, and leave slack for the power and HDMI runs.

4K or 8K?

Buy 4K unless you are going very large and sitting close. 4K is the sweet spot because it is the resolution content is mastered and delivered in: streaming services, discs, current consoles and a growing share of sports all output it, so nothing has to be reconstructed by the processor before it reaches the screen. That means your money goes into brightness, local dimming and HDR performance rather than into pixels you cannot resolve from the sofa.

Step up to 8K only if you are buying 80 inches or larger and your seating is inside about ten feet, which is where a 4K grid can begin to show. At 75 inches and under, the honest position is that almost nobody separates the two from a normal seating position. Native 8K content is still close to nonexistent, so an 8K set spends its working life upscaling the same 4K sources this page is full of.

4K OLED or 4K QLED, and which suits your room?

Both are 4K, so this is a contrast-versus-brightness decision rather than a resolution one. Choose a 4K OLED if you watch mostly after dark or can pull the blinds, if film and prestige series are your staple, or if people watch from well off-center. Per-pixel light control gives it black that read as a switched-off screen, and the picture holds its color right out to the edges of the room.

Choose a 4K QLED from the LED range if the room has big windows, daytime sports are the main event, or you want the most screen for the budget. It pushes far more light, and its quantum-dot layer keeps color strong at brightness levels that would wash an OLED out. The trade-off runs theother way: blacks lift toward
gray in dark scenes, bright objects can bloom against them, and the picture
flattens if you sit off to one side. Same money, different rooms.

Screens are hard to judge from a spec sheet, so it is worth seeing one lit up. Our showrooms let you compare brightness, contrast and motion side by side, and there are eleven of them across South Florida and metro Atlanta.

Florida. Miami, Dadeland and South Dade in the Miami area, Sawgrass Mills in Sunrise, Outlet Center in Lauderhill, Deerfield Beach, Dania Pointe in Dania Beach, and West Palm Beach.
Georgia. North Atlanta, South Atlanta in Stockbridge, and Kennesaw.

Each store page has the address, phone number and current showroom hours. You can also find the store nearest you or order online and collect in store.

Buy whichever way suits you. Compare 4K TVs side by side at any of our showrooms across Florida and Georgia, order online and collect in store, or have your new set delivered to your door. Financing is available on qualifying purchases, including a lease-to-own route that needs no credit. Bring your viewing distance, and we can help you match it to the right screen size.
