These days, no home is complete without an updated TV. With the current options available, even entry-level models blow away the best sets from the 90s and early 2000s. Since the multitude of modern TV options can be confusing, you might feel discouraged to upgrade from your current TV. Refresh rate, high dynamic range (HDR), soundbar options, OLED vs QLED technology, and built-in streaming apps are all worth considering, but it’s important to understand what these mean before making a purchase.
In this buying guide for TVs, we’ve synthesized all of the important information to help homeowners enjoy an optimal viewing experience. Keep reading below to learn more from the This Old House Reviews Team.

液晶显示器
液晶显示器stands for liquid crystal display. LCD TVs are lightweight and typically thin, and they’re also the most common type of TV. In the mid-to-late 2000s, LCDs replaced cathode-ray televisions, or CRTs. LCD TVs were once cutting-edge and exorbitantly expensive, but now they’re on the budget end of modern TVs.
Though affordable, LCDs consume more power and provide a duller image compared to other TV models that use more advanced screen technology. The reduction in image quality is in part due to the poorer contrast ratio and inferior color gamut.
引领
LED电视通常可以互换或与LCD电视结合使用。LED代表发光二极管,其中LCD电视的背光使用二极管单独点亮。LED电视通常与LCD电视一样长。您可以将LED视为使用LCD作为照明功能平台的电视。
LED-BACKLIT电视有三种主要配置:
- 完整阵列:Full-array LEDs offer the best lighting experience a “traditional” LED TV can provide. In a full-array model, the LEDs are evenly distributed behind the entire TV screen. This provides a more uniform backlight and better local dimming, which can turn entire zones of LEDs off or on in a fraction of a second.
- Edge-lit:Instead of the even LED distribution of a full-array design, edge-lit LED TVs consist of LEDs placed around the edges or perimeter of the screen. Some models may have LEDs on the left and right sides of the screen or top and bottom, while others may have LEDs around the entire screen. Models with partial edge-lit screens are ultra-thin, but users may notice some spots on the screen to be brighter than others.
- Direct-lit:引领TVs with a direct-lit display have a similar design to full-array LEDs. The primary difference is that there are fewer LEDs evenly distributed behind the screen. The downside to this direct-lit design is that the LEDs can’t be controlled separately to consistently produce a bright and vibrant image. As such, direct-lit LED TVs are slightly thicker than full-array or edge-lit models and make up a majority of budget or low-end options on the market.
OLED
OLED代表有机发光二极管。OLED电视基于标准LED电视的技术,但它们使用发射像素而不是传播像素。OLED电视的发射像素不需要单独的光源激活它们,例如背光。这意味着,当未激活像素以在屏幕上产生图像时,它确实被关闭,从而可以延长寿命和更少的功耗。
The benefits of OLED TVs include a fast response time, good brightness and contrast, a superior viewing angle, and compatibility with battery-driven applications, among other benefits. Conversely, even though the emissive pixels are turned off when they’re not activated, the blue organic material used in OLED TVs is subject to moisture migration and can cause longevity issues for some users. Additionally, some OLED TVs may be difficult to read in direct sunlight.
QLED
量子点发光二极管的缩写,Q引领TVs also built upon the technology used in regular LED TVs. Unlike OLED TVs, QLED models use a backlight system that displays a significantly brighter picture compared to a standard LCD model. QLEDs also use quantum dots, or microscopic molecules, that emit their own distinctly colored light when activated by an external light source.
尽管由于使用的背光而导致的QLEDS往往比OLED稍厚,但它们会产生更明亮的图片,这使它们成为接收大量阳光的房间的理想选择。由于QLED的亮度通常优于其他类型的电视,因此对比度也更好。
4K UHD
4K TVs are often referred to as 4K UHD, which stands for Ultra-High Definition. The terms “4K” and “4K UHD” are sometimes used interchangeably. TVs with an ultra HD display have a resolution that’s exactly four times the resolution of traditional HD displays. Most 4K TV models have a resolution of 3840×2160 pixels, or a total of approximately 8.3 million pixels.
While regular LCD, LED, QLED, and OLED TVs refer to the specific type of display, 4K UHD is a measurement of the resolution output. To get the most out of a 4K-capable display, you’ll want a TV that’s at least 55 inches or larger. Additionally, not everything is shot or available to display in true 4K UHD—though as of 2023, there’s more 4K content to enjoy than five years ago. 4K content can be in the form of movies, video games, TV shows, and other media. Next-gen gaming consoles such as the Xbox Series X or Playstation 5 are capable of playing 4K UHD media.
Key Features
TV features may be limited in entry-level models, and extensive in larger, high-end models. Here’s a breakdown of some of the most important features commonly found in TVs.
Screen Size
Entry-level TVs typically have a screen size no smaller than 32 inches, but some models may be as small as 24 inches. TVs with a screen size smaller than 32 inches may be referred to as mini TVs. 40 and 55-inch TVs are fairly common in many households, with 55 inches being large enough to situate in a living room for an entire family. A 40-inch TV may be better suited for a bedroom rather than a common area.
TVs 65 inches or longer are heavier and more expensive than smaller models, but they offer the best viewing experience in big, open areas such as a grand room. Keep in mind that a TV’s screen size is measured diagonally from one corner to the other rather than straight across on the top or bottom. This means that the dimensions of your TV vary and will be longer than the advertised screen size. In the world of TVs, depending on the display technology used in a certain model, bigger often means better.
Smart vs. Standard TVs
Most TVs available online are considered “smart” TVs. This refers to the built-in software and access to streaming platforms and other applications rather than the display technology. Standard TVs, conversely, don’t have any built-in software systems. The main difference between smart TVs and standard TVs is that a smart TV can access the internet via Wi-Fi, while a standard TV cannot. With a smart TV, it’s easy to watch movies, TV shows, and other media through Netflix, Hulu, Roku, Amazon Prime Video, and other major streaming platforms.
Common smart TV platforms include:
- Android TV
- Amazon Fire TV
- Google TV
- Roku TV
- Tizen (Samsung)
- WebOS (LG)
Unlike a standard TV, the primary drawback of smart TVs is that users may be subject to advertisements, and their data can be sold, posing potential security concerns. The camera or microphone features of a smart TV have also raised concerns among some consumers.
解决
分辨率是指创建显示屏的电视屏幕后面的列和排行榜的物理数量。1920乘1080像素(或1080p)是许多低至中端高清电视的共同分辨率。通常,像素的分辨率或数量越大,图像越清晰和富裕。
At 3840×2160, 4K UHD TVs provide a resolution that’s nearly twice that of full HD TVs and three times that of standard HD, or 720p. Consider that TVs with a 4K UHD display should be at least 55 inches or wider to display the brilliance of the resolution. If you’re looking for a 40-inch TV or smaller, a 1080p resolution should meet your viewing needs.
HDR
High Dynamic Range attempts to show the viewer a lifelike image, rich with contrast, brightness, and deep hues of color. The dynamic range refers to the extremes in contrast between darkness and brightness—the greater the range, the greater the detail. HDR-capable TV displays can read information and present an image from a wider gamut of color and brightness compared to models that don’t support a high dynamic range.
Note that if you wish to stream HDR content on your HDR-capable TV, you’ll need a relatively fast internet connection to support this. If your bandwidth is high enough—at least 15-25 Mbps—you should be able to enjoy on-demand HDR content.
可视角度
TV manufacturers recommend viewing the TV at a certain angle and distance to provide the viewer with the truest image possible. When viewing the TV too far from the side, the image may appear distorted or inaccurate to the viewer. Some TVs retain better image accuracy when viewing from the side than others, which is partially determined by the viewing angle.
If you plan on sitting directly in front of your TV to watch, you don’t need to worry about the viewing angle. For those with multiple couches or pieces of furniture that face a different angle in front of the TV, you’ll want to look for a model with a wider viewing angle. OLED TVs have an average viewing angle of 70 degrees from the center and are generally better when viewing from the side compared to LED or QLED TVs, which have a viewing angle of 20 to 40 degrees.
Sound
As the picture quality of TVs continues to improve, the built-in sound is becoming more of an afterthought from manufacturers. The ultra-thin design of modern TVs doesn’t leave much space for built-in speakers, but some models feature Dolby Atmos audio paired with Dolby Vision for clear, synced audio and video. Without a premium built-in sound system, understanding dialog may be difficult, as many TVs have only two speakers in them.
If your goal is to build a home theater, a separate soundbar or full-on surround sound system is recommended for an immersive cinematic experience. Some soundbars can be connected wirelessly with Bluetooth, while others require a wired connection.
Inputs and Outputs
Even in the era of wireless connectivity, the best smart TVs still come with multiple inputs and outputs to hook up a variety of electronics. You can usually find these inputs and outputs on the side of your smart TV. While users may be limited in the functionality of inputs and outputs on a standard TV, it’s worth noting that a standard model still has certain connections.
The most common inputs and outputs on TVs include:
- Multiple HDMI ports, including HDMI ARC
- Ethernet for hardwired internet
- Digital Coax audio
- USB输入
- RF (Radio Frequency) inputs
- 立体声声音输入/输出
Other Features
Additional features that affect a TV’s overall functionality and versatility include the remote control design, built-in stand or wall mount compatibility, and bonus cables included by the manufacturer. Most modern smart TVs are also Bluetooth-compatible, allowing users to connect a variety of devices without using any cables.
How Much Should You Spend on a TV?
你的商店uld expect to spend $400 to $500 on a mid-size TV with decent picture quality. Deals during certain times of the year, such as Black Friday or Cyber Monday, may help you save a few hundred dollars. Otherwise, larger high-end TV models like 65-inch TVs or 85-inch TVs can cost upwards of $1,500 or $2,000 for the best size, technology, and viewing experience available. Typically speaking, the larger the TV size, the more expensive it is.
