Probably The Name Of The Video Electronics Standards Association, Abbreviated As Vesayou Have Heard It Is Known.
Nowadays, many digital products and monitors are VESA standards fulfilled. But what is the VESA community, What people or companies does it consist of, what tasks does it have, and what goals does it pursue?
The mass production of electronic devices worldwide will confuse consumers and waste producers’ resources if it is not subject to specific standards. For this reason, organizations that operate primarily in non-profit mode are formed to establish clear rules, principles, and factors in each field to define the standards of each lot. One such organization is the Video Electronics Standards Association or VESAIs.
While various companies compete with each other in the world of technology, the necessity of complying with VESA standards is digital product manufacturers. Does this forum’s activity impact the end consumer?
In this article, with VESAand its activity, and then the essential standards presented by this association and the importance of VESA activity check
What is the VESA standard?
Video Electronics Standards Association, or VESAIt, was officially registered in 1989 in California. Today, this association develops and publishes various standards for personal and professional computers (workstations). More than 300 major technology companies, including AMD، Apple، Google، Intel، LG، NVIDIA، Qualcomm، Samsung, and…, are members of this forum and the VESA standards.
The most critical VESA standards
Although the VESA standard is not the only one that publishes various specifications for computer equipment, this article will examine the most critical standards presented by this association.
VESA mounting interface standard
Flat screen installation interface ( FDMI) or VESA MountIt is designed to standardize narrow and flat display back panel mounting patterns. Therefore, buyers of monitors produced by different brands do not need to prepare a unique base to install these products.
In this regard, FDMIIt consists of five standards for mounting the monitor on the central stand and four criteria for mounting the monitor on the back edge to ensure a specific standard for all screens of different dimensions. Based on FDMI standards, the stand of large monitors must support 250 pounds (113.398 kg).
If you are planning to buy a stand to mount your monitor, VESA mounting standards prevent you from getting confused, and you can choose the right mood for your monitor easily.
DisplayPort standard
Engman VESA, standards related to DisplayPort to replace this interface with DVI، VGA, SCART, and RGB developed that can transmit audio and video data on a single cable. As expected, DisplayPort HDMI’s main competitor is considered in image transmission. Generally, DisplayPortHigher bandwidth than HDMIhas, Which means it can have more resolution and frame rate than HDMI support.
For example, the maximum bandwidth of the latest HDMI standard; means HDMI 2.1 reaches 48 Gbps, while DisplayPort 2.0It has a bandwidth of 80 gigabits per second for audio and video data transfer. VESA Association, a standard called DisplayPort UHBRcompiled to help users choose the suitable cable for their display.
The advantage of DisplayPort compared to HDMI is that it is not only limited to higher bandwidth, but this port also allows connecting different monitors in series with each other. So you can use a DisplayPort cable or Mini DisplayPortConnect for two or more monitors. Since laptops and other portable devices are usually equipped with a video output port, this feature comes in handy when using two or more monitors.
DisplayHDR standard
Many of today’s modern TVs, monitors, and displays use the HDR technology they support. When the manufacturers claim their product HDR technology helps. They refer to the display’s ability to display colors realistically and vividly. If an independent organization does not prove the claims made by the creators, each of the creators has its definition of HDR. For this reason, they provide the VESA Association, the DisplayHDR standard compiled.
DisplayHDR is an open standard with a completely transparent process that ensures that all displays with this certificate meet the association’s standards.
Currently, two categories of DisplayHDR certificationSeparate for LED monitorsو YOU AREThere is:
If you plan to buy an HDR display, you have the DisplayHDR certificate; you can find your desired product in the list provided by VESACheck out. To access this list, go to Displayhdr.org/certified-products See.
AdaptiveSyncand MediaSync
Over time, more powerful graphics cards have been released that provide higher frame rates when playing computer games. Although today’s gaming monitors can support the output of powerful graphics cards, the constant operation of the display at high frequencies, such as 144 Hz, is unnecessary. For this reason, manufacturers have introduced a new variable frame rate feature in the display panel.
Since there were no specific criteria to ensure the performance of variable frame rate displays, the VESA Association has provided standards.
Monitors or laptops that meet the VESA variable frame rate standard can meet a frequency of less than or equal to 60 Hz ( AdaptiveSync) or 48 Hz ( MediaSync) and over 144 Hz ( AdaptiveSync) or 60 Hz ( MediaSync) to work. The frame rate of displays that support the variable frame rate feature is not limited to a certain number, and as a result, the efficiency of these products increases.
CPU and graphics card manufacturers, including Apple، AMD، Intel، Mediatek, ، NVIDIAand SamsungAdaptiveSync feature support. So, if you buy a monitor that meets VESA standards for the variable frame rate, you’ll probably be able to use this feature without worry.
Other VESA Association standards
In addition to the standards discussed in this article, the VESA AssociationIt has developed other measures that have not been welcomed. Among these, we can refer to the VESA Digital Flat Panel standard mentioned as a replacement for the VGA connector provided. Also, VESA Plug standards و Display Standard, a substitute for the DVI connector, have been presented and have not been able to attract the attention of technology companies.
Conclusion
However, the VESA Association now has over 300 members and is as prominent as the HDMI ConsortiumNot with more than 1500 members. It plays an essential role in technology, especially in the computer industry.
Many VESA standards regarding DisplayPortand AdaptiveSync technology seem suitable for computer use. However, the standards developed by VESA are rarely used in television or other displays. For example, high-end gaming computers often use the frame rate used by the AdaptiveSync technology they support.
Despite all the points mentioned, VESA standards provide clear criteria for evaluating digital products, thus ensuring buyers that each manufacturer does not have its interpretation of the characteristics of the technology.
How do we know which VESA standard we are using?
To find out the version of the VESA standard, you can refer to the device specifications. It is also possible to measure the distance of the holes with a ruler.
