Amazon Basics DisplayPort to DVI Cable with Gold-plated connectors (1.8 m/6 Feet)

Product Information

If the monitor turns on correctly, then the computer is the source of the problem. If it doesn’t, then the monitor may be an issue. You may need to restart your second computer once connected to really rule out the tower being the issue. Even better, if your computer has a secondary video card, try to connect the monitor to that card and then remove the initial video card. You Need To Update Your Software To The Latest Versions The DisplayPort standard does not specify any maximum length for cables, though the DisplayPort 1.2 standard does set a minimum requirement that all cables up to 2 meters in length must support HBR2 speeds (21.6 Gbit/s), and all cables of any length must support RBR speeds (6.48 Gbit/s). [37] :§5.7.1, §4.1 Cables longer than 2 meters may or may not support HBR/HBR2 speeds, and cables of any length may or may not support HBR3 speeds or above.

The tables below describe the refresh frequencies that can be achieved with each transmission mode. In general, maximum refresh frequency is determined by the transmission mode (RBR, HBR, HBR2, HBR3, UHBR 10, UHBR 13.5, or UHBR 20). These transmission modes were introduced to the DisplayPort standard as follows: Link training with adjustable amplitude and preemphasis adapts to differing cable lengths and signal quality DisplayPort 1.2 has more bandwidth at 21.6 Gbit/s [74] (17.28 Gbit/s with overhead removed) as opposed to HDMI 2.0's 18 Gbit/s [75] (14.4 Gbit/s with overhead removed).

Currently, DisplayPort is the most widely implemented alternate mode, and is used to provide video output on devices that do not have standard-size DisplayPort or HDMI ports, such as smartphones, tablets, and laptops. A USB-C multiport adapter converts the device's native video stream to DisplayPort/HDMI/VGA, allowing it to be displayed on an external display, such as a television set or computer monitor. DisplayPort has historically had higher bandwidth than the HDMI standard available at the same time. The only exception is from HDMI 2.1 (2017) having higher transmission bandwidth @48 Gbit/s than DisplayPort 1.3 (2014) @32.4 Gbit/s. DisplayPort 2.0 (2019) retook transmission bandwidth superiority @80.0 Gbit/s.

VESA - Interface Standards for The Display Industry. 15 February 2017. DisplayPort can be used to transmit audio and video simultaneously, although each can be transmitted without the other. The video signal path can range from six to sixteen bits per color channel, and the audio path can have up to eight channels of 24-bit, 192 kHz uncompressed PCM audio. [1] A bidirectional, half-duplex auxiliary channel carries device management and device control data for the Main Link, such as VESA EDID, MCCS, and DPMS standards. The interface is also capable of carrying bidirectional USB signals. [5] Audio data is transmitted across the main link during the video blanking intervals (short pauses between each line and frame of video data).

Unfortunately, there are many reasons why your DVI to Displayport is not working, so you will have to run through the different solutions to see what your reason is. If you cannot connect the DVI to the Displayport monitor, it could be that something is wrong with your computer’s graphics card. Try to reset or replace your graphics card, paying close attention to compatibility. In April 2013, VESA published an article stating that the DisplayPort cable certification did not have distinct tiers for HBR and HBR2 bandwidth, and that any certified standard DisplayPort cable—including those certified under DisplayPort 1.1—would be able to handle the 21.6 Gbit/s bandwidth of HBR2 that was introduced with the DisplayPort 1.2 standard. [42] The DisplayPort 1.2 standard defines only a single specification for High Bit Rate cable assemblies, which is used for both HBR and HBR2 speeds, although the DP cable certification process is governed by the DisplayPort PHY Compliance Test Standard (CTS) and not the DisplayPort standard itself. [37] :§5.7.1, §4.1 SlimPort, a brand of Analogix products, [93] complies with Mobility DisplayPort, also known as MyDP, which is an industry standard for a mobile audio/video Interface, providing connectivity from mobile devices to external displays and HDTVs. SlimPort implements the transmission of video up to 4K-UltraHD and up to eight channels of audio over the micro-USB connector to an external converter accessory or display device. SlimPort products support seamless connectivity to DisplayPort, HDMI and VGA displays. [94] The MyDP standard was released in June 2012, [95] and the first product to use SlimPort was Google's Nexus 4 smartphone. [96] Some LG smartphones in LG G series also adopted SlimPort.If your monitor worked previously, it is likely something to do with the hardware or software. You’ve either blown something or there needs to be an update to make it work again. According to a roadmap published by VESA in September 2016, a new version of DisplayPort was intended to be launched in "early 2017". It would have improved the link rate from 8.1 to 10.0 Gbit/s, a 23% increase. [29] [30] This would have increased the total bandwidth from 32.4 Gbit/s to 40.0 Gbit/s. However, no new version was released in 2017, likely delayed to make further improvements after the HDMI Forum announced in January 2017 that their next standard (HDMI 2.1) would offer up to 48 Gbit/s of bandwidth. According to a press release on 3 January 2018, "VESA is also currently engaged with its members in the development of the next DisplayPort standard generation, with plans to increase the data rate enabled by DisplayPort by two-fold and beyond. VESA plans to publish this update within the next 18 months." [31] At CES 2019, VESA announced that the new version would support 8K @ 60 Hz without compression and was expected to be released in the first half of 2019.
