DisplayPort is a digital display interface standard designed to replace VGA, DVI, and HDMI. There are different versions of the DisplayPort standard, and the latest is version 1.2. DisplayPort 1.1 is an older standard, and there are some differences between it and DisplayPort 1.2. One of the most significant differences is that DisplayPort 1.2 supports 4K resolution at 60 Hz, while DisplayPort 1.1 does not.
What is DisplayPort?
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). It is used to connect a computer to a monitor, television, or projector.
DisplayPort can transmit video, audio, and data over a single cable. It supports resolutions up to 8K and bandwidths up to 32Gbps.
DisplayPort is backwards compatible with HDMI and VGA. It can be used to connect devices that use those interfaces, such as monitors and televisions.
DisplayPort is often used in gaming laptops and desktop computers because it provides high-bandwidth connections for displays with high resolutions and fast response times.
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The first version, DisplayPort 1.0, was released in 2009. DisplayPort 1.1 and 1.2 are both minor updates that were released in 2011 and 2013, respectively.
What is DisplayPort 1.1
DisplayPort 1.1 is a digital display interface developed by the Video Electronics Standards Association (VESA). It was designed to replace DVI, VGA, and other older display interfaces. DisplayPort 1.1 can support video resolutions up to 4K, and it’s also capable of carrying audio signals. DisplayPort 1.1 is backwards compatible with DisplayPort 1.0 and earlier versions of the standard.
What is DisplayPort 1.2
DisplayPort 1.2 is the latest update to the DisplayPort standard, released in February 2014. It offers a number of enhancements over DisplayPort 1.1, including support for 4K resolutions at up to 120 Hz, 8-channel audio, and higher bandwidth (32.4 Gbps). DisplayPort 1.2 is backwards compatible with DisplayPort 1.1 devices, and can be used to connect devices such as monitors, laptops, and graphics cards.
DisplayPort 1.1 vs 1.2: what are the differences?
DisplayPort is a digital display interface used to connect a computer to a monitor. There are several versions of DisplayPort, and it can be confusing to know which one to use. we will compare DisplayPort 1.1 and 1.2 and explain the differences between them.
Bandwidth
DisplayPort 1.2 can transmit data at a rate of up to 21.6 Gbps, which is about 2x the bandwidth of DisplayPort 1.1. This increased bandwidth allows for higher resolution displays and greater color depth. DisplayPort 1.2 also supports Multi-Stream Transport (MST), which allows multiple displays to be connected to a single port.
Resolution
DisplayPort is a type of digital display interface, and while the first version, DisplayPort 1.0, had a maximum resolution of 2,560 x 1,600 at 60 Hz, the latest version, DisplayPort 1.2, can handle resolutions up to 4,096 x 2,160 at 60 Hz. There’s a significant difference in resolution between DisplayPort 1.1 and DisplayPort 1.2 – DisplayPort 1.2 can handle resolutions up to four times higher than DisplayPort 1.1. This means that if you have a monitor or television that supports 4K resolution (3,840 x 2,160), you’ll need to use DisplayPort 1.2 in order to take advantage of that resolution; using DisplayPort 1.1 with a 4K monitor or television will result in a lower resolution.
Support for HDR
With the release of DisplayPort 1.2 in September 2012, High Dynamic Range (HDR) support was added as one of the main features. HDR is a technology that allows for a wider range of colors and brightness to be shown on a display, making it look closer to what we see in the natural world. It also allows for images with a higher contrast ratio, which means blacks will be blacker and whites will be whiter. While DisplayPort 1.1 does not include HDR support, DisplayPort 1.2 does. This is because HDR requires more bandwidth than what is available in DisplayPort 1.1. In order to take advantage of HDR with DisplayPort 1.2, you’ll need a monitor that supports the feature, and your graphics card will need to be able to output at least 10 bits per channel (bpc).
More Efficient Power Usage
DisplayPort 1.2 offers increased bandwidth over DisplayPort 1.1, which means that it can support higher resolutions, color depths and refresh rates. This makes DisplayPort 1.2 a better choice for monitors that require more bandwidth to function properly. However, DisplayPort 1.2 also requires more power than DisplayPort 1.1. This can be a problem for devices that are already limited in terms of power consumption, such as laptops and mobile devices. DisplayPort 1.1 is still a viable option for many devices, especially if power consumption is not a major concern. For monitors that require more bandwidth, DisplayPort 1.2 is the best option available currently.
Reduced Latency
DisplayPort has come a long way since its introduction in 2007. The first version, DisplayPort 1.0, had a bandwidth of 4.95 Gbit/s. In 2013, the second version, DisplayPort 1.2, was released with a bandwidth of 8.64 Gbit/s. This increase in bandwidth was necessary to enable 4K and 8K displays. However, the increase in bandwidth also introduced a new problem: latency. Latency is the time it takes for data to travel from the source to the display. With DisplayPort 1.1, latency was about 165 microseconds (μs). With DisplayPort 1.2, latency was about 260 μs. That’s an increase of about 55%. This increase in latency can be a problem for applications that require low latency, such as gaming and virtual reality (VR).
Supported Platforms
The version of DisplayPort is 1.2. It offers several improvements over the previous version, including support for 4K resolutions at 60 Hz and 8K resolutions at 30 Hz. It also supports HDR10 and provides a higher bandwidth of up to 32 Gbps. DisplayPort 1.1 is still widely used, however it does not support 4K resolutions at 60 Hz or 8K resolutions at 30 Hz. It also has a lower bandwidth of up to 21 Gbps.
Daisy Chaining
DisplayPort 1.1 and 1.2 are both capable of daisy chaining, but there are some key differences. With DisplayPort 1.1, each downstream port can support a maximum of four displays, while with DisplayPort 1.2, each downstream port can support a maximum of eight displays. Additionally, DisplayPort 1.2 introduces the capability for Multi-Stream Transport (MST), which allows multiple displays to be driven from a single source by splitting the signal into multiple streams. This can be used to drive more displays or to provide higher resolutions and refresh rates on existing displays.
Conclusion: which is better?
DisplayPort 1.2 offers enhanced features and performance that make it the best choice for transmitting video and audio. It supports 4K resolution at 60Hz, has a higher bandwidth capacity, and includes other enhancements that make it an ideal choice for gamers and professionals. If you’re looking for the best possible display performance, DisplayPort 1.2 is the way to go.
