- Backlighting is the illumination of a screen e.g. LCD (liquid crystal display). There are several types of backlighting with LEDs, e.g. full array, edge lit.
- The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.
- The video modes that can be displayed by the device.
- The graphic resolutions that can be displayed by the device. The graphic resolution describes the width and height dimensions of a display, such as a computer monitor, measured in pixels.
- Describes which motion interpolation technology device uses e.g. BLS (Back Light Scanning), PPR (Picture Perfection Rate), PMR (Perfect Motion Rate), TruMotion.
- The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.
- This is the size of the display screen, measured diagonally.

- The supported protocols for exchanging analog signals.
- The protocols supported for exchange of digital signal.
- Smart TV features access to a large number of channels that offer TV programs, movies, and music without the need to connect a TV antenna or subscribe to a cable/satellite service. Some smart TVs provide web browsing, gaming, and access to compatible media content stored on computers.
- Digital distribution of television content via the Internet. Internet television is a general term that covers the delivery of television shows and other video content over the Internet by video streaming technology, typically by major traditional television broadcasters.
- Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.
- The version of the operating system used e.g. 4.1, 4.2 for Android.
- The quantity of speakers included in/with the product.
- RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplifiers and loudspeakers.
- Device or software capable of decoding a digital stream of audio e.g. internet radio.
- Popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.
- An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.
- The type of wireless local area network (LAN). It can be ad-hoc, where units in a network communicate peer-to-peer, or Infrastructure, where units communicate with each other via an access point A LAN interconnects computers in a small area e.g. home, school or office.
- Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.
- The type of bluetooth technology in the product e.g. Bluetooth Smart (v4.0).
- The product can be used wih VESA mounting interfaces.
- What the casing of the product is made of.
- The colour e.g. red, blue, green, black, white.
- The TV has Teletext, which is a means of sending text and diagrams to a properly equipped television screen by use of one of the vertical blanking interval lines that together form the dark band dividing pictures horizontally on the television screen. It offers a range of text-based information, typically including news, weather and TV schedules. Subtitle (or closed captioning) information is also transmitted within the television signal (usually accessed by pressing 888 on the remote control.
- The type of video formats that can be used by this device.
- The audio formats which this device or software can read/use e.g. MP3, MP4.
- The type of image files that the device can use/display e.g. gif, JPEG (jpg).
- This means that LEDs can be controlled individually (or in clusters) to control the level of light/color intensity in a given part of the screen.
Ports & interfaces
- High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across connections.
- Number of Ethernet LAN (RJ-45) ports (connecting interfaces) in the device. Ethernet LAN (RJ-45) ports allow a computer to connect to the ethernet.
- Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.
- The socket (port) for the composite video input (white cable).
- The socket in the device for the digital audio output. The signal is carried via an optical cable with an TOSLINK connector.
- Number of sockets /ports where headphones are connected.
- The number of sockets (ports) for RF (radio frequency) connections.
- Technology which allows separation of conditional access functionality from a digital TV receiver-decoder (Host) into a removable conditional access module (CAM). It is also referenced as DVB-CI for Digital Video Broadcast - Common Interface. The host is responsible for tuning to pay TV channels and demodulation of the RF signal, while CAM is responsible for CA descrambling. The Common Interface allows them to communicate with each other.
- In Digital Video Broadcasting, the Common Interface (CI) is a technology which allows separation of conditional access functionality from a digital TV receiver-decoder (Host) into a removable conditional access module (CAM). CI+ or Common Interface Plus implements a form of copy protection between a Conditional Access Module (CAM) and the television receiver (Host). CI+ is backward compatible with CIv1. Old television receivers, which have CIv1 CI-slot, can be used with CI+ CAM and vice versa, but for viewing only those of TV programs which are not marked as CI+ protected.
- The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.
- The socket (port) to receive input from a PC via a D-sub, which is a connector with a characteristic D-shaped metal shield.
- An Electronic Programme Guide (EPG) allows device users to navigate scheduling information menus interactively, selecting and discovering programming by time, title, station, or genre using an input device such as a keypad, computer keyboard, or TV remote control. Its interactive menus are generated entirely within local receiving or display equipment using raw scheduling data sent by individual broadcast stations or centralized scheduling information providers. A typical IPG provides information covering the next 7 or 14 days.
- There is a timer for when to turn the device on or off.
- The Google Assistant is a virtual assistant developed by Google that is primarily available on mobile and smart home devices. Unlike Google Now, the Google Assistant can engage in two-way conversations
- Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.
- The amount of electricity that is consumed when the product is on standby.
- The voltage of the AC electricity that is inputted into the product.
