Note however that HDMI does support digital audio, whereas DVI is purely a video standard. So you do need an active adapter to make the conversion. For resolutions above HD, however, there is High Speed HDMI, which diverts from the dual link DVI you would use. This applies to single link DVI, supporting resolutions up to 2048 x 1200. Using a simple connector-to-connector type adapter cable, you could switch from DVI to HDMI and vice versa.
They both use TMDS (Transition-Minimized Differential Signaling), a technology to transmit data. Because HDMI was created as a follow-up to DVI, the two standards were very similar at the beginning. DVI, HDMI and DisplayPortįirst, let’s talk about the similarities between DVI and HDMI. Although certainly not a general truth, it is more likely you want to connect a DisplayPort output to an HDMI input than the other way round. Oddly enough, this means that the display ports are usually HDMI ports. In other words, we could say that DisplayPort comes from the video source side (AV receivers, computers, etc.), and HDMI more from the visualization side (HDTV, projectors, etc.).
HDMI was conceived by manufacturers of displays, whereas DisplayPort comes from the IT-world. But what exactly is going on inside these adapters, and is converting DP to HDMI always that easy? And is there a difference between consumer and professional use? In this article, we explore the complete reasoning.Īs already explained in a previous article, DisplayPort and HDMI were created by different consortiums, with different applications in mind.
The reason? An HDMI to DisplayPort conversion always requires an active instead of a passive adapter. But if you want to go the other way round, you will need to dive a whole lot deeper into your pockets. DisplayPort to HDMI adapters generally cost about 7 dollars.
