50- and 60-Inch Televisions
Televisions can make the shows or movies you're watching come alive. When manufacturers, such as LG, Samsung, and Panasonic, design large-screen TVs, they select from different types of screen technology, such as plasma TV displays or performance features, like refresh rate. Find the 50- or 60-inch high-definition TV that's perfect for your needs and preferences.What does resolution, refresh rate, and contract mean?
- The resolution is measured by the number of pixels that can be shown. It is a good reference point for the quality of picture that you can expect. Common resolutions are 480p, 720p, 1080p, and 4K. The 480p resolution does not support HD, whereas the 720p supports half, and the 1080p and 4K support full.
- The refresh, or frame, rate represents the number of images per second that can be processed and viewed. Common refresh rates are 60Hz, 120Hz, 240Hz, and 600Hz. Higher refresh rates reduce potential ghosting and improve the discernible picture quality. Plasma produces the highest refresh rate.
- The contrast ratio signifies the difference between the brightness and darkness of a TV. A higher contrast produces better image quality. While there is native and dynamic contrast, native represents what the TV can naturally perform and is the better number to review. Dynamic contrast is easier than native to manipulate into a large number.
- LCD, or Liquid Crystal Display, units are the industry standard. Their refresh rate ranges between 60Hz and 240Hz. They are typically less expensive than other types of 50-inch and bigger units.
- LED, or Light Emitting Diode, units are improved LCDs. This updated design improves efficiency, reduces the size, and makes the unit lighter. LEDs are either Direct or Edge-lit.
- Plasma produces the highest refresh rate at 600Hz. This allows viewers to watch a Plasma at any angle without losing clarity. Plasma TVs are often considered superior to LCD and LED TVs regarding colour accuracy and contrast.
- OLED, or Organic Light Emitting Diode, models are the only type that can be curved and flexed. This technology is revolutionary, and the curve allows for a vastly different viewing perspective compared to a regular, flat unit. OLEDs are thinner and lighter than those above.
Important HDTV features are HDMI ports, smart TV capability, audio ports, and Ethernet ports. Many devices that can connect to plasma TVs and others utilize HDMI ports. The number of these ports will determine how many separate pieces of hardware you can connect. Depending on the type of audio port installed, sound can be greatly enhanced. Ethernet ports allow you to connect to the internet at the best speed possible for your connection. A smart TV screen supports many internet applications and benefits from greater internet connection speeds.
