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. 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.
Because P&D was a physically large, expensive connector, a consortium of companies developed the DFP standard (1999), which was focused solely on digital video transmission using a 20-pin micro ribbon connector and omitted the analog video and data capabilities of P&D. [4] :3 [5] :4 DVI instead chose to strip just the data functions from P&D, using a 29-pin MicroCross connector to carry digital and analog video. [8] Critically, DVI allows dual-link TMDS signals, [9] meaning it supports higher resolutions than the single-link P&D and DFP connectors, which led to its successful adoption as an industry standard. Compatibility of DVI with P&D and DFP is accomplished typically through passive adapters that provide appropriate physical interfaces, as all three standards use the same DDC/EDID handshaking protocols and TMDS digital video signals. [10] :§1.3.7 Technical overview [ edit ] Simple passive adapters only work from DisplayPort to DVI. You will need to buy a more expensive active adapter to send a signal in the other direction, from DVI to DisplayPort. These are less common than DisplayPort to DVI solutions. Other benefits of HDMI include functions such as HDMI-CEC (HDMI Consumer Electronics Control), which allows you to control numerous devices with one remote. For example, connect a soundbar to your television through an HDMI-CEC compatible port and the soundbar can turn on and off with your television and be controlled by a single remote. If you want to combine the graphics outputs of your motherboard and your dedicated graphics card, this can be possible with certain Intel processors. This uses a “hybrid multi-monitor” mode but will be dependent on the chipset and possibly the motherboard used. You might also need to upgrade the BIOS to get it working. Intel lists the following chipsets as compatible in this hybrid mode: Hybrid multi-monitor support is officially supported with Intel Embedded Graphics Drivers for systems using the Intel Q45/G41/G45 and GM45/GL40/GS45 chipsets, or later. How to get 144Hz: Which cable is needed for 144Hz? Fortunately, DisplayPort is compatible with DVI; you just need to buy the correct cable or adapter.
What are the different types of DVI cables?
Digital video pixel data is transported using multiple TMDS twisted pairs. At the electrical level, these pairs are highly resistant to electrical noise and other forms of analog distortion. The differences between single-link and dual-link refer to how much bandwidth the cable can carry. A single-link DVI-D or DVI-I cable can carry 3.96 Gbit/s, which tops out at 1,920 x 1,200 resolution. Dual-link, on the other hand, physically has extra pins on the connectors, allowing a maximum bandwidth of 7.92 Gbit/s and 2,560 x 1,600 resolution. Although DVI is still a common connection, it’s becoming dated, so if you want to output a very high resolution you’ll need to use HDMI or DisplayPort instead.

Retrieved 31 January 2023.For those of us who game, you might be wondering what’s the best cable to use to achieve a 144hz refresh rate. There are various cables you can use, but you should pay close attention to the version of your output port and that of your monitor.
Under most circumstances, you can get away with using whichever cable you have lying around – and whatever works – but if you have more specific needs, such as carrying audio, displaying a higher resolution or outputting a higher refresh rate for gaming, you’ll need to be more discerning with your choice of cable. You must buy the correct adapter for the job, as all of these solutions are unidirectional and will only send video in one direction.Our USB cablesare another handy household essential, letting you link up your PC or laptop with devices such as your camera or scanner for easy data transfer.

Retrieved 31 January 2023.Digital Visual Interface ( DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content.

December 2010) Another less common version is dual-link (or DVI-DL), which has a second internal connection for delivering data and can be used for high-resolution displays up to 2560×1600/60Hz. There are three types of DVI cables and connections, and each has a slightly different pin configuration:
