A 50-inch LCD (LED) Ultra HD TV from TCL, with 2160p resolution, and a claimed 120-hertz refresh rate (may not be true native frame rate), three HDMI inputs, no component-video inputs, and one USB port. This TV is internet enabled.


The TCL 50S423 is a 50-inch LCD (LED) Ultra HD TV with a native resolution of 3840x2160 (2160p). Rather than the basic 60Hz, it claims a faster 120Hz frame rate, a feature designed to reduce motion blur.

It includes an Ethernet jack allowing for a wired connection to your home network. It is also WiFi capable, so you can connect it to your home network wirelessly. It is DLNA certified, so you can view digital photos stored on a compatible computer, phone, or other mobile device also connected to your home network.

This TV has three HDMI inputs, and no component-video inputs. It also has one USB port, which may be used to play media--photos, videos, and music--stored on a flash drive.

The TCL 50S423 measures 28.25 inches high by 44.5 inches wide by 10 inches deep, including its base. The panel itself is 3.25 inches thick including any protrusions, and the screen has a glossy finish.

The warranty on this model covers parts for 12 months and labor for 12 months.


HDMI input HDMI input The total number of HDMI inputs on the TV. HDMI (High-Definition Multimedia Interface) is a digital audio/video connection found on TVs, monitors, Blu-ray players, DVD players, receivers, media players, cameras and digital TV tuners. HDMI is the preferred type of A/V connection between TV and device, over an analog component, composite, or RF (such as from a cable box).
Component-video Component-video The total number of component-video inputs on the TV. Component-video is a high quality analog video connection that can accept high definition 1080i/p or 720p, or standard definition 480i/p. Component-video connections require three separate RCA jacks.
Component/Composite-video shared inputs Component/Composite-video shared inputs Component/Composite-video shared inputs (total/aux). One of the three component video input RCA jacks doubles as a composite-video input. This means you can only plug in one type or the other at any given time.
Composite-video Composite-video Number of composite-video inputs on the TV. A composite video signal is analog, and carries standard definition (480i) video only, no audio. Composite is often used to connect older equipment like a VCR, or older camera and camcorder models, to your TV.
USB port USB port USB port lets you connect a flash drive for playback of multimedia content such as videos, photos, and music.
VGA input VGA input VGA (Video Graphics Array) connector is essentially a standard connection for video on computers and monitors, and becoming less common on high-definition TVs, in favor of an HDMI connection. This type of input is no longer available on most TVs.
Ethernet port Ethernet port Ethernet is the common wired network connection that allows TVs to access to the Internet. TVs with an Ethernet port typically have WiFi capability as well, but a wired connection is generally considered more reliable.
Digital-audio output Digital-audio output The TV comes with either a coaxial or optical digital-audio output to let you route the audio soundtrack to an external receiver. The receiver thus splits apart the soundtrack for distribution to various speakers in the room.
Headphone jack (3.5mm audio jack) Headphone jack (3.5mm audio jack) When you want to watch TV without disturbing others, a headphone jack (usually on the front or side of the set) lets you plug in headphones via a stereo mini jack. You are more likely to find this feature on smaller screen TVs.
Other connections Other connections Other connections not mentioned above.


Frame rate (Hz) Frame rate Frame rate indicates the manufacturer's claim of how often a TV refreshes its picture in a second.

Native resolution Native resolution Applies to "fixed-pixel" display types such as LCD (LED), OLED. Native resolution is expressed in horizontal by vertical pixels (for example: 1920x1080 for an HD display).
Overall height (in.) Overall height The height of the TV in inches, rounded up to the nearest 0.25-inch. Dimensions include the base and detachable speakers, important if you plan to place the TV on a stand or in an entertainment center. See "Panel size without base" if you plan to wall-mount only the display.
Overall width (in.) Overall width The width of the TV in inches, rounded up to the nearest 0.25-inch. Dimensions include the base and detachable speakers, important if you plan to place the TV on a stand or in an entertainment center. See "Panel size without base" if you plan to wall-mount only the display.
Overall depth (in.) (in.) Overall depth (in.) The depth of the TV in inches, rounded up to the nearest 0.25-inch. Dimensions include the base and detachable speakers, important if you plan to place the TV on a stand or in an entertainment center. See "Panel size without base" if you plan to wall-mount only the display.
Screen shape (aspect ratio) Screen shape (aspect ratio) The screen shape, or aspect ratio, is the proportion of a TV screen's width to its height. Current HD and UHD TVs have a wide, “16:9” aspect ratio, unlike older tube TVs screens with an aspect ratio of "4:3," giving them a squarish shape.
Screen finish Screen finish The reflectivity of the display's surface. A screen with a mirror-like, or glossy finish may introduce distracting reflections from nearby lighting or windows. A matte screen is better for reducing glare in rooms with many lights, but these are not typically found on displays larger than 32".
Digital Tuner (Off-air ATSC and Cable QAM) Digital Tuner (Off-air ATSC and Cable QAM) An ATSC tuner can receive free over-the-air local broadcast digital signals, which may include high-definition widescreen images and multi-channel sound. All HDTVs and Ultra HD TVs have a built-in ATSC tuner that only require a VHF/UHF indoor or a roof antenna to receive the broadcast networks' high-definition (HD), or standard-definition (SD) program offerings. You must be close enough to a station transmitter, with few obstructions blocking the signal, in order for the TV to pick up the channels. Also note that you won't get any of the premium channels typically offered only on cable or satellite.
Panel size without base HxWxD (in.) Panel size without base HxWxD For flat-panel LCD and OLED sets, dimensions are for the display panel only, not including the base and detachable speakers, rounded up to the nearest 0.25-inch; also see "Overall height (in.)", "Overall width (in.)", and "Overall depth (in.)".

Warranty (months): parts/labor/in-home Warranty (months): parts/labor/in-home The length of time the product is covered by its manufacturer for defects or repairs. Warranty coverage is often divided into parts and labor. Twelve months for both is typical. With an in-home warranty, a technician comes to your home to service the set when you have a problem -- of particular importance with heavy or wall-mounted sets.
