| Ports & interfaces | |
| Video port type The type of socket in the device for connecting a video e.g. SCART. | VGA |
| VGA (D-Sub) ports quantity Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM. | 5 |
| RS-232 ports The number of sockets (ports) for RS-232. An RS-232 serial port was once a standard feature of a personal computer, used for connections to modems, printers, mice, data storage, uninterruptible power supplies, and other peripheral devices. Now it has been largely replaced by USB and other ports. | 1 |

| Bandwidth Bandwidth is the difference between the upper and lower frequencies in a continuous set of frequencies. It is typically measured in Hertz (Hz). A key characteristic of bandwidth is that any band of a given width can carry the same amount of information, regardless of where that band is located in the frequency spectrum. For example, a 3 kHz band can carry a telephone conversation whether that band is at baseband (as in a POTS telephone line) or modulated to some higher frequency. | 300 MHz |
| Maximum resolution The maximum number of pixels that can be displayed in the image. It is usually quoted as width × height,: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. | 1920 x 1440 pixels |
