DisplayPort version

The version of the DisplayPort and/or miniDisplayPort interface used by the graphics card. For the interfaces themselves, see the relevant help items; here we recall that they differ only in the type of plug. So the list of versions for both cases is the same, it looks like this:

— v 1.2. The earliest widely used version (2010). However, already in this version, 3D compatibility and the daisy chain mode appeared. The maximum fully supported resolution when connecting a single monitor is 5K (30 fps), transmission up to 8K is possible with certain restrictions; a frame rate of 60 Hz is supported up to a resolution of 3840x2160, and 120 Hz — up to 2560x1600. And when using daisy chain, you can connect up to 2 2560x1600 screens at 60 frames per second or up to 4 1920x1200 screens at the same time. In addition to the original version 1.2, there is an improved v 1.2a, the main innovation of which was support for AMD FreeSync, a technology used in AMD video cards to synchronize the refresh rate of the monitor with the actual frame rate output by the video adapter.

— v 1.3. An update introduced in 2014. The increased bandwidth made it possible to provide full, without restrictions, support for 8K at 30 fps, as well as transmit 4K images at 120 fps, sufficient for 3D work. Resolutions in daisy chain mode have also increased — up to 4K (3840x2160) at 60 fps for two screens and 2560x1600 at the same frame rate for four. Of the specific innovations, it is worth me...ntioning the Dual Mode mode, which allows you to connect HDMI and DVI devices to such a connector through the simplest passive adapters.

— v 1.4.Version introduced in March 2016. Formally, the bandwidth has not increased compared to the previous version, but thanks to signal optimization, it became possible to work with 4K and 5K resolutions at 240 fps and with 8K at 120 fps. However for this, the connected screen must support DSC encoding technology — otherwise, the available resolutions will not differ from version 1.3. In addition, v 1.4 added support for a number of special features, including HDR10, and the maximum number of simultaneously transmitted audio channels increased to 32.

—v 1.4a. An update released in 2018 "quietly" — without even an official press release. The main innovation was the update of Display Stream Compression technology from version 1.2 to version 1.2a.

Length

The total length of the graphics card.

In this case, the length means the size of the device from the plate with connectors (which is attached to the back wall of the system unit) to the opposite side. The plate itself and the outwardly protruding connectors are usually not taken into account.

Data on the length of the graphics card is needed primarily in order to assess whether there is enough space for it in a particular case. In addition, longer boards, usually, have more advanced characteristics (although there is no hard dependence here, and video adapters of similar class may have different lengths). As for specific values, the most compact solutions nowadays have a size of 150 – 200 mm or less ; an indicator of 200 – 250 mm can still be considered relatively small, 250 – 290 mm — medium, and many models (mostly advanced) have a length of more than 290 mm.
