In the ever-evolving landscape of television technology, consumers are presented with an array of choices that offer a superior viewing experience at increasingly affordable prices. From sleek flat-panel displays to expansive projection systems, the options cater to a variety of preferences and room sizes. High-definition (HD) models dominate the market, providing crystal-clear images that bring cinematic quality into the living room. As technology advances, prices continue to drop, making cutting-edge TVs more accessible than ever before.
The majority of new television models now feature high-definition (HD) digital technology, a significant shift from the analog TVs that have been the norm since the 1950s. HD TVs offer an unparalleled home video experience with their ability to display the intricate details contained in HD signals. Most HD signals come in 1080i or 720p resolution, but newer, pricier TVs are emerging with 1080p resolution, promising even higher picture quality. However, 1080p models are expected to become more widespread as more TV programming adopts this high resolution.
Enhanced-definition (ED) TVs, which display 480p resolution, are a step down from HD. While they can convert HD signals, the resulting picture quality doesn't quite match that of true HD. Standard-definition signals, still used for most TV broadcasts, contain up to 480 interlaced lines (480i).
To receive high-quality HD signals, digital TVs require a digital tuner. Integrated HD sets come with a built-in digital tuner for off-air antenna reception, but require an external device for cable or satellite HD signals. HD-ready TVs, which lack a built-in digital tuner, are less expensive but also need an external box for over-the-air broadcasts. Government regulations now mandate built-in tuners in larger TVs, and smaller sets will follow suit in the coming years.
Conventional TVs with cathode-ray tubes (CRTs) continue to offer the best performance-to-value ratio and have a proven track record for reliability. These sets typically range from 13 to 36 inches and come in both 4:3 and 16:9 aspect ratios. Slimmer models are now available, addressing the bulkiness of traditional CRTs. Prices start at around $75 for 13-inch sets and can go up to $500 or more for 36-inch sets, with HD models costing about $200 extra.
LCD TVs are known for their lightweight, thin design and are available in sizes from 13 to 45 inches. They can be placed on a table or wall-mounted, and some models can even be suspended under a cabinet. LCD TVs come in both 4:3 and 16:9 aspect ratios and in analog, ED, and HD models. Prices for LCD TVs start at approximately $600 for smaller models and can exceed $2,000 for larger sizes.
Plasma displays, typically larger than LCDs, are available in sizes like 42 and 50 inches. They can be wall-mounted and offer bright, colorful displays, even in well-lit rooms. Prices for plasma TVs start at around $2,300.
Rear-projection TVs using CRT technology are the most affordable option for large screens, typically ranging from 42 to over 60 inches. HD models are becoming standard as analog versions phase out. Prices for HD-capable sets start at about $1,800.
Microdisplays use LCD, DLP, or LCoS technology to create images and are slimmer and lighter than CRT-based rear-projection TVs. They range from 40 to 82 inches, with prices starting at $2,500.
Front projectors can produce the largest images, up to 200 inches diagonally, but require a separate screen or wall and a tuner. They use microdisplay technologies like LCD, DLP, and LCoS and are best for a home theater experience. Prices range from $1,500 to $5,000.
Modern TVs typically feature a flat screen to reduce reflections and picture-in-picture (PIP) capability. Motion compensation, also known as 3:2 pulldown compensation, is a feature that improves the smoothness of movies. Aspect ratio is crucial for HD sets, with wide-screen 16:9 models becoming more common. Stretch and zoom modes help adjust the image to fit the screen shape, reducing the risk of "burn-in" from static images.
Inputs for connecting other components include antenna/cable (RF), composite video, S-video, component-video, DVI, HDMI, VGA, front-mounted A/V, audio outputs, and a headphone jack.

Interesting stats and trends in television technology are often overlooked. For instance, the adoption rate of smart TVs has been steadily increasing, with a report by Statista projecting that 119 million smart TV units will be sold worldwide in 2021. Additionally, the market for 8K TVs, although still in its infancy, is expected to grow at a compound annual growth rate (CAGR) of 55.5% from 2021 to 2027, according to a report by Grand View Research.
When considering a new TV purchase, consumers should stay informed about the latest advancements and how they align with their viewing preferences and budget.
