HDMI has seen numerous revisions since its inception in 2002. Its most common version, used in most consumer devices at present, is 1.4 but there’s a newer, more exciting 2.0 specification now becoming more prominent. The main difference between the 1.4 and 2.0 specifications focus around bandwidth available. HDMI 1.4 has a bandwidth maximum of 10.2 Gbps/s whereas the HDMI 2.0 tops out at 18 Gbps/s. The host system's software also needs to support MST for hubs or daisy-chains to work. While Microsoft Windows environments have full support for it, Apple operating systems currently do not support MST hubs or DisplayPort daisy-chaining as of macOS 10.15 ("Catalina"). [56] [57] DisplayPort version 1.4a was published in April 2018. [25] VESA made no official press release for this version. It updated DisplayPort's DSC implementation from DSC 1.2 to 1.2a. [26] 2.0 [ edit ] Two 4K ( 3840 × 2160) displays @ 144 Hz and 8 bpc (24 bit/px, SDR) RGB/Y′C BC R 4:4:4 color (uncompressed) A newer 1.3 and 1.4 version, that both have a maximum data rate of 25.92 Gbits/sec, are both becoming more widely available. With the increased bandwidth capabilities, it opens up the floodgates to higher resolutions such as 7,680 x 4,320 (8K).
so what I'm trying to find out is if there is another adapter i could use to get the second monitor to connect and work properly. DisplayPort 1.1 added optional implementation of industry-standard 56-bit HDCP ( High-bandwidth Digital Content Protection) revision 1.3, which requires separate licensing from the Digital Content Protection LLC. [8] :§1.2.6 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. A DisplayPort cable is a digital audio and video network channel that helps transmit data to your TV screen so that you can view your content in the best possible way. Certified by VESA, this cable connection comes in two variants - standard and Mini DisplayPort. Although both these variants are different in sizes, they transmit identical signals.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.
The total bandwidth of the main link in a standard 4-lane connection is the aggregate of all lanes: The transmission mode used by the DisplayPort main link is negotiated by the source and sink device when a connection is made, through a process called Link Training. This process determines the maximum possible speed of the connection. If the quality of the DisplayPort cable is insufficient to reliably handle HBR2 speeds for example, the DisplayPort devices will detect this and switch down to a lower mode to maintain a stable connection. [8] :§2.1.1 The link can be re-negotiated at any time if a loss of synchronization is detected. [8] :§1.7.3 Although DisplayPort has much of the same functionality as HDMI, it is a complementary connection used in different scenarios. [71] [72] A dual-mode DisplayPort port can emit an HDMI signal via a passive adapter. The first version, 1.0, was approved by VESA on 3 May 2006. [6] Version 1.1 was ratified on 2 April 2007, [7] and version 1.1a was ratified on 11 January 2008. [8]

Similar to DisplayPort, an Alternate Mode using Type-C USB can be used to connect an HDMI-compliant device to a receiving device. Thunderbolt We outline the different types of connections below and give you different usage scenarios to help you decide. We’ll also outline the best connection and cable to choose for 144Hz and other higher refresh rate displays. This article may contain unverified or indiscriminate information in embedded lists. Please help clean up the lists by removing items or incorporating them into the text of the article. ( November 2010)
The Mini DisplayPort connector was developed by Apple for use in their computer products. It was first announced in October 2008 for use in the new MacBooks and Cinema Display. In 2009, VESA adopted it as an official standard, and in 2010 the specification was merged into the main DisplayPort standard with the release of DisplayPort 1.2. Apple freely licenses the specification to VESA.All features of DisplayPort will function across any DisplayPort cable. DisplayPort does not have multiple cable designs; all DP cables have the same basic layout and wiring, and will support any feature including audio, daisy-chaining, G-Sync/ FreeSync, HDR, and DSC.
Great Deal
