Before picking the right ruggedized Industrial Monitor or Industrial Touchscreen for your application, let’s understand the different types of Display Interfaces.
Here’s a quick summary of the Video Input Connector Types:
- HDMI: Audio and video signal, best for TV to PC connections.
- DVI: Video only, perfect for older systems or for 144Hz at 1080p.
- DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.
- VGA: Old, legacy video connector. Only to be used when nothing else available.
- USB-C: Formally known as USB Type-C. Connects to both hosts and devices, replacing various electrical connectors including
- USB-B and USB-A, HDMI, DisplayPort and 3.5mm audio cables and connectors.
Thunderbolt: A hardware interface developed by Intel (in collaboration with Apple) that allows the connection of external peripherals and monitors to a computer. Thunderbolt 1 and 2 use the same connector as Mini DisplayPort, and Thunderbolt 3 uses the USB-C connector from USB. - AV (RCA): AV input is a common label on a RCA type connector to receive analog (AV) Audio / Visual (CVBS composite video) signals from electronic equipment that generates AV signals (AV output).
- NDI: Network Device Interface – Format that allows you to send audio and video via ethernet network
- SDI: SDI Serial Digital Interface is a professional video signal that is preferred in production environments because of its longer range (up to 300 feet) and reliability, since it’s typically sent along BNC Cabling that has specialized connectors on each end to lock into the devices they connect to.
Previously, only an analog VGA interface was utilized to connect a rugged LCD monitor to the computer. With the development of new technologies for flat-panel monitors, the capabilities of the VGA connector have become insufficient. To attain the highest image quality, you need to use a digital standard, such as DVI. Manufacturers of devices for home entertainment have created the HDMI standard, which became the digital successor of the analog scan connector. Somewhat later, VESA (Video Electronics Standards Association) designed DisplayPort. As mentioned earlier, modern devices are equipped with various monitor ports: HDMI, DVI, VGA, DisplayPort (DP), USB-C, Thunderbolt, SDI. Let’s consider each of the interfaces.
Monitor with HDMI port – the king of multimedia. HDMI Monitors
HDMI stands for High Definition Multimedia Interface. In modern home entertainment devices, such as flat-panel TVs and Blu-ray players, HDMI is the standard connection interface. As in the case of DVI, the signal is transmitted in digital format, which means maintaining the original quality. Together with HDMI, HDCP (High Bandwidth Digital Content Protection) technology was developed to prevent the piracy and illegal copying of video materials. The first devices with HDMI support appeared in late 2003. Since then, the standard has been changed several times; in particular, support of new audio and video formats has been added. Precisely why did HDMI become so popular?
- Length of cabling up to 25-30 meters;
- Sound transmission (even multi-channel) together with video – no need for separate speakers;
- Convenient small connectors;
- Support for many different devices: players, TVs, projectors, DVRs, game consoles, etc.;
- Ultrahigh resolutions;
- 3D-picture; possible together with ultra-high resolutions (versions of HDMI 4b and 2.0).
The prospects for HDMI are the most promising – development keeps moving. In 2013, the specifications of version 2.0 were adopted; this standard is compatible with old wire connectors, but it supports resolutions that are more impressive and other excellent features.
In conclusion
Having become acquainted with all types of ports, now you understand what exactly you need. Regardless of what suits your requirements best, you can find different sizes of touchscreen monitors with any ports you need among the range of products at Industrial Touch Monitor.
