DisplayPort version 1.4a was published in April 2018. [25] VESA made no official press release for this version. It updated DisplayPort's DSC implementation from DSC 1.2 to 1.2a. [26] 2.0 [ edit ] Other benefits of HDMI include functions such as HDMI-CEC (HDMI Consumer Electronics Control), which allows you to control numerous devices with one remote. For example, connect a soundbar to your television through an HDMI-CEC compatible port and the soundbar can turn on and off with your television and be controlled by a single remote. Standard DisplayPort cable connections do not use the DP_PWR pin. Connecting the DP_PWR pins of two devices directly together through a cable can create a short circuit which can potentially damage devices, since the DP_PWR pins on two devices are unlikely to have exactly the same voltage (especially with a ±10% tolerance). [45] For this reason, the DisplayPort 1.1 and later standards specify that passive DisplayPort-to-DisplayPort cables must leave pin 20 unconnected. [8] : §3.2.2 On the monitor side however, it sounds like the monitor itself may be pure digital. My guess is that DVI-D to Display port with work, HDMI to Display Port, and obviously Display port to Display port because they're all digital.

Long story short, it's cheaper to go all digital from a manufacturing perspective, no more A to D conversion, and the picture looks better anyways. They probably just don't have the A to D hardware in the monitor and really didn't gear the thing for people putting the adapter on the other end.DisplayPort-to-DVI and DisplayPort-to-HDMI adapters/cables may or may not function from an MST output port; support for this depends on the specific device.

HDMI is unique among the many connection options in that it’s able to carry both uncompressed video and uncompressed audio. This is why it’s become the connection of choice for most multimedia devices as it’s a one-cable solution.Choose HDMI 2 if DisplayPort isn’t available or if you require audio over 144Hz (as DVI doesn’t support audio) Updates to HDMI have kept the standard relevant for over 18 years. The earliest versions of HDMI have become outdated, but later versions have increased bandwidth and features. More often than not, if you’re connecting something to a television, HDMI will be your best, and likely only, bet. Most PC monitors will also include an HDMI input. The good news, where it comes to 1.4 versus 2, is that you don’t need to rush out and buy new cables. To take advantage of the 2.0 specyou just need both devices on each end of the cable to be 2-compatible. Any HDMI cable will do, and we’ve already seen that there’s no difference in HDMI cable quality.
