Most monitors will have a range of different inputs available, and your PC or laptop will also use different outputs, so it can be difficult to decide which is the best connection to use. To understand the above chart in context, we need to go deeper. What all digital connections — DisplayPort, HDMI and even DVI-D — end up coming down to is the required bandwidth. Every pixel on your display has three components: red, green, and blue (RGB) — alternatively: luma, blue chroma difference, and red chroma difference (YCbCr/YPbPr) can be used. Whatever your GPU renders internally (typically 16-bit floating point RGBA, where A is the alpha/transparency information), that data gets converted into a signal for your display. HDMI stands for High Definition Multimedia Interface. In modern home entertainment devices, such as flat-panel TVs and Blu-ray players, HDMI is the standard connection interface. As in the case of DVI, the signal is transmitted in digital format, which means maintaining the original quality. Together with HDMI, HDCP (High Bandwidth Digital Content Protection) technology was developed to prevent the piracy and illegal copying of video materials. The first devices with HDMI support appeared in late 2003. Since then, the standard has been changed several times; in particular, support of new audio and video formats has been added. Precisely why did HDMI become so popular? 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). The DisplayPort AUX channel is a half-duplex (bidirectional) data channel used for miscellaneous additional data beyond video and audio, such as EDID ( I 2C) or CEC commands. [8] :§2.4 This bidirectional data channel is required, since the video lane signals are unidirectional from source to display. AUX signals are transmitted across a dedicated set of twisted-pair wires. DisplayPort 1.0 specified Manchester encoding with a 2 MBd signal rate (1 Mbit/s data rate). [8] :§3.4 Version 1.2 of the DisplayPort standard introduced a second transmission mode called FAUX (Fast AUX), which operated at 720 MBd with 8b/10b encoding (576 Mbit/s data rate), [37] :§3.4 but it was deprecated in version 1.3.
The latest version, superMHL, adds support for 8K videos at 120fps, Dolby Atmos, HDR, etc. It also brings a new reversible superMHL connector into the picture. Also, you can connect multiple displays to a single superMHL port. Just like HDMI, DisplayPort, and Thunderbolt, there is an MHL Alternate Mode for USB Type-C. Winding Up HBR3 mode with 25.92 Gbit/s of effective video bandwidth, using CVT-R2 timings, allows eight simultaneous 1080p displays (1920 × 1080) @ 60 Hz, stereoscopic 4K UHD (3840 × 2160) @ 120 Hz, or 5120 × 2880 @ 60 Hz each using 24 bit RGB, and up to 8K UHD (7680 × 4320) @ 60 Hz using 4:2:0 subsampling [70]While the total bandwidth represents the number of physical bits transmitted across the interface, not all of the bits represent video data. Some of the transmitted bits are used for encoding purposes, so the rate at which video data can be transmitted across the DisplayPort interface is only a portion of the total bandwidth. Only certain DVI pinouts allow for analog signal conversion with a pin change. Example, a DVI-D doesn't pass through analog signals, it's digital only. Look at the port diagram, you need pins C1-C4 for the analog signal, without those, you've got nothing but a digital signal. Find sources: "DisplayPort"– news · newspapers · books · scholar · JSTOR ( April 2022) ( Learn how and when to remove this template message) HDR extensions were defined in version 1.4 of the DisplayPort standard. Some displays support these HDR extensions, but may only implement HBR2 transmission mode if the extra bandwidth of HBR3 is unnecessary (for example, on 4K 60 Hz HDR displays). Since there is no definition of what constitutes a "DisplayPort 1.4" device, some manufacturers may choose to label these as "DP 1.2" devices despite their support for DP 1.4 HDR extensions. [52] As a result, DisplayPort "version numbers" should not be used as an indicator of HDR support.
Thunderbolt 3 supports a maximum theoretical bandwidth of 40Gbit/s, capable of pushing video streams on two 4K displays at the same time. A single Thunderbolt port can connect up to 6 devices via daisy-chaining or a hub. By using the Type-C connector, it can also leverage the USB Power Delivery feature which can be used to charge a connected device using up to 100 watts of power. You will be asked, "How do you want to search for drivers?" Choose the option that says "Search automatically for drivers". Direct Drive Monitor (DDM) 1.0 standard was approved in December 2008. It allows for controller-less monitors where the display panel is directly driven by the DisplayPort signal, although the available resolutions and color depth are limited to two-lane operation. 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. If we try to compare DisplayPort and HDMI, DisplayPort may have an upper hand in the specifications department, but the reality is that HDMI has already captured most of the market. And now, makers of DisplayPort have started pushing their technology in the consumer space. Otherwise, DisplayPort has been mainly present on monitors and graphics cards.
Common, but old.

The 30 days start the day after you have notified us of the cancellation For Nvidia gamers, your best option right now is a DisplayPort 1.4 connection to a G-Sync certified (compatible or official) display. Alternatively, HDMI 2.1 with a newer display works as well. Both the RTX 30-series and 40-series cards support the same connection standards, for better or worse. Most graphics cards will come with three DisplayPort connections and a single HDMI output, though you can find models with two HDMI and two (or three) DisplayPort connections as well — only four active outputs at a time are supported. or 20 Gbit/s data rate per lane; 1, 2, or 4 lanes; (effective total 5.184, 8.64, 17.28, 25.92, or 77.37 Gbit/s for 4-lane link); 2 or 720 Mbit/s (effectively 1 or 576 Mbit/s) for the auxiliary channel.
When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.0 can enable such configurations as: [28] 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 format can only be achieved if DSC is used together with either YCbCr 4:2:2 or 4:2:0 chroma subsampling (as noted)

You will likely find that your new Ultra HD/4K TV supports HDCP 2.2 on its HDMI port, but it’s not always for all of them. Some models will only support HDCP 2.2 for HDMI 1 and HDMI 2 inputs, so if you’re connecting a shiny new Ultra HD Blu-ray player, such as the Panasonic DMP-UB900 or Samsung UBD-K8500, make sure to use the correct HDMI input.
