Reduced bandwidth transmission for 15-metre (49ft) cable, at least 1920 × 1080p @ 60 Hz at 24 bits per pixel
However, transmission mode support is not necessarily dictated by a device's claimed "DisplayPort version number". For example, older versions of the DisplayPort Marketing Guidelines allowed a device to be labeled as "DisplayPort 1.2" if it supported the MST feature, even if it didn't support the HBR2 transmission mode. [47] :9 Newer versions of the guidelines have removed this clause, and currently (as of the June 2018 revision) there are no guidelines on the usage of DisplayPort version numbers in products. [48] DisplayPort "version numbers" are therefore not a reliable indication of what transmission speeds a device can support. Support for HDR video was introduced in DisplayPort 1.4. It implements the CTA 861.3 standard for transport of static HDR metadata in EDID. [22] Content protection [ edit ]

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) I bought a 4K Lenovo monitor L28u-35. It's a 60hz monitor. It has both the Display Port 1.4 and HDMI 2.0.
Can drive display panels directly, eliminating scaling and control circuits and allowing for cheaper and slimmer displays To get 144Hz, you should ideally use DisplayPort as it’s the most capable out of the bunch. Here, DisplayPort 1.0-1.1a is able to output 144Hz at 1080p, while 1.2-1.2a can output 1440p at 144Hz, 1.3 outputs up to 120Hz at 4K, and 1.4 can output 144Hz at 4K using Display Stream Compression (DSC). It’s the best connection to display 144Hz.DisplayPort 1.2 has more bandwidth at 21.6 Gbit/s [74] (17.28 Gbit/s with overhead removed) as opposed to HDMI 2.0's 18 Gbit/s [75] (14.4 Gbit/s with overhead removed). HDR can be described as the ratio between the lightest and darkest parts of an image. Typically, with standard dynamic range, you’re losing detail at either end of the light spectrum. Expose a scene for the shadow detail and you end up with blown-out highlights or expose for the highlights and you lose shadow detail. HDR allows a greater range of detail across the full light spectrum.
In DisplayPort versions 1.0–1.4a, the data is encoded using ANSI 8b/10b encoding prior to transmission. With this scheme, only 8 out of every 10 transmitted bits represent data; the extra bits are used for DC balancing (ensuring a roughly equal number of 1s and 0s). As a result, the rate at which data can be transmitted is only 80% of the physical bitrate. The transmission speeds are also sometimes expressed in terms of the "Link Symbol Rate", which is the rate at which these 8b/10b-encoded symbols are transmitted (i.e. the rate at which groups of 10 bits are transmitted, 8 of which represent data). The following transmission modes are defined in version 1.0–1.4a: Pin 20 on the DisplayPort connector, called DP_PWR, provides 3.3 V (±10%) DC power at up to 500 mA (minimum power delivery of 1.5 W). [8] :§3.2 This power is available from all DisplayPort receptacles, on both source and display devices. DP_PWR is intended to provide power for adapters, amplified cables, and similar devices, so that a separate power cable is not necessary. Support for 8K resolution (7680 x 4320) at 60Hz refresh rate with full 4:4:4 chroma and 10-bit colour depth for HDR Unless a device can support at least one of these on top of DSC, it cannot be certified to the DP 2.1 specification. Likely Confusion and Potential Abuse To support a particular format, the source and display devices must both support the required transmission mode, and the DisplayPort cable must also be capable of handling the required bandwidth of that transmission mode.

Bad Move, Microsoft...
pins for the auxiliary channel – the auxiliary channel uses another 3-pin shielded twisted pair (pins 15–17) Make sure you're buying your DisplayPort 1.4 cables from a reputed source like Cable Matters. Most of the DisplayPort cables that Cable Matters offers are VESA Certified which means they've passed the Video Electronics Standards Association's rigorous testing requirements. There, you'll find plenty of choices, whether you want shorter, passive DisplayPort cables, or longer, active alternatives which can stretch up to 24 feet. Take a look at some of Cable Matters' cable offerings. What about DisplayPort 1.4a? Unavailable on USB-C– The DisplayPort Alternate Mode specification for sending DisplayPort signals over a USB-C cable does not include support for the dual-mode protocol. As a result, DP-to-DVI and DP-to-HDMI passive adapters do not function when chained from a USB-C to DP adapter. Link training with adjustable amplitude and preemphasis adapts to differing cable lengths and signal quality
