    Samsung UN40NU7100 TV

    A 40-inch LCD (LED) Ultra HD TV from Samsung, with 2160p resolution, and a claimed 120-hertz refresh rate (may not be true native frame rate), three HDMI inputs, one component-video input, and two USB ports. This TV is internet enabled.

    About

    The Samsung UN40NU7100 is a 40-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 one component-video input. Which also doubles as a composite-video input. It also has two USB ports, which may be used to play media--photos, videos, and music--stored on a flash drive.

    The Samsung UN40NU7100 measures 23.8 inches high by 36 inches wide by 8.3 inches deep, including its base. The panel itself is 2.3 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.

    Results in the following chart are gathered from Consumer Reports’ 2018 Winter Survey of 97,554 TVs owned by members who purchased a new set between 2010 and 2018.

    Our predicted brand reliability ratings are based on a statistical model that estimates problem rates within the first 5 years of ownership, for TVs that are not covered by an extended warranty or service contract. Higher ratings are indicative of better reliability. Brands receiving a red or orange rating cannot be recommended by CR at this time.

    Our owner satisfaction ratings are based on the proportion of members who are extremely likely to recommend their TV brand to friends and family.

    Connections

    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).
    3
    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.
    1
    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.
    1
    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.

    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.
    No
    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.
    Yes
    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.
    Optical
    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.

    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.

    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.
