With the popularity of video conferencing, modern conference systems are no longer dominated by sound reinforcement systems. Display systems have risen to become the most important system and the focus of participants' attention. In fact, the conference system encompasses multiple subsystems such as the multimedia display system, centralized control system, conference voting system, and sign-in system, and these subsystems can achieve seamless integrated operations. This article will focus on discussing how to construct and implement a high-definition conference display system.

The display system in video conferences mainly consists of projectors, projection screens or monitors, and LCD TVS, supplemented by matrix switching and signal processing equipment. However, with the emergence of high-definition video conferencing terminals, high-definition cameras, high-definition conference screen projection demonstration systems, etc., and "high definition" becoming an important indicator pursued by monitors and LCD TVS, high-definition conference display systems actually already have sufficient hardware equipment support.

1. Select high-definition display devices that meet the requirements
The physical resolution of the projector, monitor or LCD TV must be at least 1920×1080P, with a real picture ratio of 16:9, and it must not be achieved through conversion. The brightness should generally meet the requirements of meeting rooms with a brightness higher than 3000ANSI, and it should be equipped with HDMI, VGA, DVI, RGBHV components, serial control interface RS232, and composite video interface. In addition, if a projector is selected, the picture display ratio of the projection screen should also be 16:9.
2. Determine the type of signal transmission adopted for high-definition display
Digital signal display is the most ideal transmission type for high-definition video conferencing. However, to achieve digital high-definition display, a very high level of technical craftsmanship is required, and the necessary signal source should also be digital output. HDMI and DVI are more suitable for meeting rooms with a transmission distance of less than 15 meters. If the transmission distance exceeds 15 meters, HDMI extenders or DVI extenders, etc. need to be installed. If there are multiple signal sources, it is also necessary to configure VGA to DVI devices, HDMI matrices, etc., and with the assistance of various signal converters or extenders and other equipment, the transmission of high-definition digital signals in the meeting room can be completed.
If the relatively traditional analog signal transmission, namely component video transmission, is adopted at present, the transmission distance can be increased to about 30 meters by using the RGBHV port. If high-quality and high-diameter cables are used, the transmission distance can be even longer.
3. Consider the universality of signal source types
Nowadays, laptops have become the main source of video signals in meeting rooms. The external display interfaces of most laptops are HDMI interfaces, Type-C interfaces, DP (DisplayPort), some have thunderbolt interfaces, and some older models of laptops have VGA interfaces. Therefore, to achieve high-definition display, the universality of the types of signal sources also needs to be considered.
Take the source of HDMI signals as an example. First, you need to understand the maximum resolution of HDMI signals. For laptops, this means checking the maximum resolution supported by their graphics cards. In addition, if there are many input signals, the selection of high-definition matrix devices should also be considered, mainly to see if their bandwidth supports full high-definition resolution.
