Finally, DisplayPort does not support Ethernet functionality or audio return signals, making it incapable of commanding audio systems. When you convert video from a source that uses DisplayPort or Mini DisplayPort to DVI or HDMI (ex: a computer to a monitor). Consider the difference between passive and active adapters.

There are now cards with DisplayPort 2.1 support, but they're still of different levels. Intel's Arc GPUs support 10 Gbps per lane, for a 40 Gbps maximum connection speed (not including 128b/132b encoding). AMD opted for the faster 13.5 Gbps per lane (54 Gbps total), but neither company supports the potential 20 Gbps per lane variant. But perhaps the bigger issue now isn't GPU support. So if you’re looking for a DisplayPort to HDMI converter to make use of an HDMI display, you’ll need to be aware that HDMI has these limits, even if they’re unlikely to be met in most cases. DisplayPort is certainly more future-facing. What Should You Look For In A HDMI To DisplayPort connector? HDMI cables are generally capable of supporting in-built ethernet. This allows numerous HDMI-supporting devices to connect over a shared ethernet connection using a router. Such a configuration is capable of supporting speeds of up to 100Mbps. The automotive variants are an exception to this rule.
The latest display connectivity standards are DisplayPort and HDMI ( High-Definition Multimedia Interface). DisplayPort first appeared in 2006, while HDMI came out in 2002. Both are digital standards, meaning all the data about the pixels on your screen is represented as 0s and 1s as it zips across your cable, and it's up to the display to convert that digital information into an image on your screen.
Length is another important point to consider while shopping for a DisplayPort cable. Depending on the type of DP connector that you would be using at either end of the cable would decide the cable’s length. For example, when you are connecting two monitors, the length of the cable would be different from the cable length when you are connecting a PC monitor to a CPU. DP cables are available in lengths ranging from 1 meter up to 3 meters. One use case where DisplayPort is the clear winner is configurations requiring multi-display support. HDMI is an abbreviation of ‘High Definition Multimedia Interface’, and it refers to an interface that is used for transferring HD data from one device and transferring it over to another. 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.
To Conclude
HDMI 2.0 was introduced in 2013, with an enhanced data transfer speed and support for UHD content (4K at 60Hz). This iteration supported dual video streams on a single display, as well as 32 audio channels for improved quality. Soon followed HDMI 2.0a and HDMI 2.0b, adding and enhancing HDR support. The DisplayPort standard allows multiple monitors to function concurrently on a single connection. It supports stable performance and HD resolution up to 1920×1200 when four displays operate on a single connection. The connection will function even when more displays are linked as long as the maximum bandwidth is not exceeded. However, this may lead to hampered performance. 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.
