pins for external connectors on desktops, notebooks, graphics cards, monitors, etc. and 30/20 pins for internal connections between graphics engines and built-in flat panels.

DisplayPort 1.0 includes optional DPCP (DisplayPort Content Protection) from Philips, which uses 128-bit AES encryption. It also features full authentication and session key establishment. Each encryption session is independent, and it has an independent revocation system. This portion of the standard is licensed separately. It also adds the ability to verify the proximity of the receiver and transmitter, a technique intended to ensure users are not bypassing the content protection system to send data out to distant, unauthorized users. [8] :§6 DisplayPort 1-1.1a is able to output 144Hz at 1080p, while 1.2-1.2a can output 1440p at 144Hz, 1.3 outputs up to 120Hz at 4K, and 1.4 can output 144Hz at 4K using Display Stream Compression (DSC). Most motherboards and dedicated graphics cards will have multiple outputs. You can use a combination of these to output to multiple monitors. So if you have HDMI and DVI outputs, connect one monitor using HDMI and the other using DVI. As mentioned above, if you’re using DisplayPort and your graphics card or device supports Multi-Stream Transport, you can daisy-chain DisplayPort and USB-C monitors, too.With a maximum data rate of 25.92 Gbps, DisplayPort 1.4 can handle 4K resolution 24-bit color at 98 Hz, and dropping to 4:2:2 YCbCr gets it to 144 Hz with HDR. Alternatively, DSC allows up to 4K and 240 Hz, even with HDR. Keep in mind that 4K HDR monitors running at 144 Hz or more carry premium pricing, so gamers will more likely be looking at something like a 144Hz display at 1440p. That only requires 14.08 Gbps for 24-bit color or 17.60 Gbps for 30-bit HDR, which DP 1.4 can easily handle. DSC can provide up to a 3:1 compression ratio by converting to YCgCo and using delta PCM encoding. It provides a "visually lossless" (and sometimes even truly lossless, depending on what you're viewing) result. Using DSC, 8K 120 Hz HDR is suddenly viable, with a bandwidth requirement of 'only' 42.58 Gbps. HBR3 (High Bit Rate 3): 8.10 Gbit/s bandwidth per lane (810 MHz link symbol rate), introduced in DP 1.3 DisplayPort version 1.2a was released in January 2013 [15] and may optionally include VESA's Adaptive Sync. [16] AMD's FreeSync uses the DisplayPort Adaptive-Sync feature for operation. FreeSync was first demonstrated at CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard, [17] and after a proposal from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an optional feature of the main DisplayPort standard under the name "Adaptive-Sync" in version 1.2a. [18] As it is an optional feature, support for Adaptive-Sync is not required for a display to be DisplayPort 1.2a-compliant. The connection with the help of USB connector became possible when version 3.0 appeared. Using the DisplayLink adapter, you can connect a monitor with a DVI / HDMI connector to the USB port of your laptop or computer. Such ports are the standard for connecting external devices, which all manufacturers of these devices are eager for. USB ports connect mice, keyboards, printers, scanners, modems, card readers, flash drives, cameras, cell phones, players, hard drives, optical drives, etc. This connector is needed for those who plan to work simultaneously with multiple monitors.

In accordance with The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 we would like to make you aware of the following important information: I know that HDMI can be very slow (depending on monitor)... sometimes as much as 5 seconds to see the new source. I assumed that was content protection built into the standard and/or slow decoder ASIC. VGA ports were introduced in 1987, so needless to say, they may be a little outdated for the technology of today. Over the years, technology developed and we came across HDMI ports, DVI ports, and more to help us efficiently connect our displays with our audio/visual devices. The first version of DisplayPort was ratified in 2008. It was designed to become the one-stop solution for all your needs, replacing VGA, DVI, and other formats in the process. Today, most displays are DisplayPort-compatible. However, you may need a DisplayPort cable to help connect your current devices with some other older ones.

Three QHD ( 2560 × 1440) @ 120 Hz and 8 bpc (24 bit/px, SDR) RGB/Y′C BC R 4:4:4 color (uncompressed) Multi-Stream Transport is a feature first introduced in the DisplayPort 1.2 standard. It allows multiple independent displays to be driven from a single DP port on the source devices by multiplexing several video streams into a single stream and sending it to a branch device, which demultiplexes the signal into the original streams. Branch devices are commonly found in the form of an MST hub, which plugs into a single DP input port and provides multiple outputs, but it can also be implemented on a display internally to provide a DP output port for daisy-chaining, effectively embedding a 2-port MST hub inside the display. [37] :Fig. 2-59 [55] Theoretically, up to 63 displays can be supported, [37] :20 but the combined data rate requirements of all the displays cannot exceed the limits of a single DP port (17.28 Gbit/s for a DP 1.2 port, or 25.92 Gbit/s for a DP 1.3/1.4 port). In addition, the maximum number of links between the source and any device (i.e. the maximum length of a daisy-chain) is 7, [37] :§2.5.2 and the maximum number of physical output ports on each branch device (such as a hub) is 7. [37] :§2.5.1 With the release of MST, standard single-display operation has been retroactively named "SST" mode (Single-Stream Transport). a b c d e f g Although this format slightly exceeds the maximum data rate of this transmission mode with CVT-R2 timing, it is close enough to be achieved with non-standard timings Updates to HDMI have kept the standard relevant for over 18 years. The earliest versions of HDMI have become outdated, but later versions have increased bandwidth and features.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. Monitor with Display Port – only becomes ubiquitous. Three 10K ( 10240 × 4320) displays @ 60 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (with DSC)

HDMI is unique among the many connection options in that it’s able to carry both uncompressed video and uncompressed audio. This is why it’s become the connection of choice for most multimedia devices as it’s a one-cable solution. USB Type-C: Newest audio, video, data and power connector. The best connection for laptops and mobile devices NDI: Network Device Interface - Format that allows you to send audio and video via ethernet network Display port to just about anything else on the computer side works because the computer is built to handle both the analog and digital output needed to make it happen, it's part of the standard. 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.Because the standard has evolved over the years, not all DisplayPort cables will work properly at the latest speeds. The original Display 1.0-1.1a spec allowed for RBR (reduced bit rate) and HBR (high bit rate) cables, capable of 5.18 Gbps and 8.64 Gbps of data bandwidth, respectively. DisplayPort 1.2 introduced HBR2, doubled the maximum data bit rate to 17.28 Gbps and is compatible with standard HBR DisplayPort cables. HBR3 with DisplayPort 1.3-1.4a increased things again to 25.92 Gbps, and added the requirement of DP8K DisplayPort certified cables. Use a can of compressed air to remove foreign materials from the DisplayPort on the monitor and your computer. If using a DisplayPort adapter on your computer, ensure the cable is correctly plugged into the adapter and the adapter into your computer. Switch the cable to a different DisplayPort if the adapter has more than one port. 2. Install the Monitor Drivers Similar to DisplayPort, an Alternate Mode using Type-C USB can be used to connect an HDMI-compliant device to a receiving device. Thunderbolt High-resolution displays and multiple displays with a single connection, via a hub or daisy-chaining [69] You might think it's a simple matter of hooking up whatever cable comes with your monitor to your PC and calling it a day, but there are differences that can often mean a loss of refresh rate, color quality, or both if you're not careful. Here's what you need to know about DisplayPort vs. HDMI connections.
