Introduction to HDMI and DisplayPort
Two cable standards are big in digital video and audio. Before we compare HDMI cables, let’s know what each does. They both carry pictures and sounds, but in different ways.
What is HDMI?
HDMI means High-Definition Multimedia Interface. It has a 19-pin setup to send both video and audio in one cord. You’ll see it on Blu-ray players, TVs, laptops, and gaming consoles from Sony and Microsoft.
HDMI comes in three sizes for different devices:
- Standard HDMI — used in TVs and desktop monitors
- Mini HDMI — common on tablets and some cameras
- Micro HDMI — built into compact recording equipment and small devices
HDMI supports top audio formats like Dolby Atmos. It also gives strong video, great for low-brightness scenes.
What is DisplayPort?
DisplayPort was made by VESA (Video Electronics Standards Association). It has a 20-pin connector with a built-in lock. This lock keeps the cable in place during use, which pros like.
One big DisplayPort benefit is Multi-Stream Transport (MST). It lets you connect up to four displays from one cord. Gamers and multimedia pros on PC use this every day.
| Feature | HDMI | DisplayPort |
|---|---|---|
| Pin Count | 19 pins | 20 pins |
| Locking Mechanism | No | Yes |
| Multi-Display from One Port | Not supported | Up to 4 displays (MST) |
