HDMI Cable Standards
Understanding HDMI Cable Standards helps you choose the right cable for your needs. These standards have changed over time to support better video and audio quality. The CTA/EIA 861 series sets the rules for how HDMI cables work. You can see how the technical details have improved by looking at the way signals travel through the cable.
TMDS Signal | Pin Number |
CLK (+) | 10 |
CLK (-) | 12 |
CLK (Shield) | 11 |
DATA0 (+) | 7 |
DATA0 (-) | 9 |
DATA0_Shield | 8 |
DATA1 (+) | 4 |
DATA1 (-) | 6 |
DATA1_Shield | 5 |
DATA2 (+) | 1 |
DATA2 (-) | 3 |
DATA2_Shield | 2 |
CEC | 13 |
HEC Data- | 14 |
SCL (Serial Clock for DDC | 15 |
SDA (Serial Data Line for DDC) | 16 |
DDC / CEC / HEC Ground | 17 |
+5 V Power (50 mA max) | 18 |
Hot Plug Detect (1.3) / HEC Data+ (1.4) | 19 |
The HDMI Cable Standards use TMDS (Transition Minimized Differential Signaling) to send data. Each cable has 19 conductors, including four twisted pairs for clock and data channels. Higher TMDS clock speeds let cables carry more data. This means you get higher resolutions and deeper colors. The EIA/CEA-861 standard defines how video formats and timing work with these cables.
HDMI Cable Connector Types
Type A HDMI Connector
Type A is the most common HDMI connector. You see it on most TVs, monitors, game consoles, and home theater receivers. This connector has 19 pins. It measures about 13.9 mm wide and 4.45 mm high. You can easily spot it because it looks like a flat, wide rectangle.
- Where you find it:
- TVs
- Projectors
- Blu-ray players
- Streaming devices
- Game consoles
Type A connectors work with all standard HDMI cables. You use them for both video and audio signals. If you connect a TV to a streaming box or a gaming console, you probably use a Type A connector.
Tip: When you buy a new HDMI cable for your TV or computer monitor, check if it has Type A connectors on both ends. Most home setups use this type.
Type B HDMI Connector
Type B HDMI connectors are rare. You do not see them in most homes or offices. This connector has 29 pins, which is more than Type A. It measures about 21.2 mm wide and 4.45 mm high. Type B was designed for very high-resolution displays.
- Where you might find it:
- Early professional video equipment
- Some special medical or industrial devices
Type B supports dual-link connections. This means it can send more data than Type A. However, most devices never used this connector. The HDMI 1.3 update made Type B less important because Type A could handle higher speeds.
Note: You probably do not need to worry about Type B connectors. Most modern devices do not use them.
Type C HDMI Connector
Type C is also called the Mini HDMI connector. It is smaller than Type A but still has 19 pins. The connector measures about 10.42 mm wide and 2.42 mm high. You find Type C on smaller devices that need to save space.
- Where you find it:
- Digital cameras
- Camcorders
- Some tablets
- Portable media players
Type C connectors let you connect small devices to TVs or monitors. You often use a cable with a Type C connector on one end and a Type A connector on the other. This way, you can show photos or videos from your camera on a big screen.
Tip: If you want to connect your camera to a TV, look for a Mini HDMI (Type C) to Standard HDMI (Type A) cable. Always check your device’s manual to see which connector it uses.
Type D HDMI Connector
Type D HDMI connectors are also called Micro HDMI connectors. You see these on very small devices. Type D is even smaller than Type C (Mini HDMI). It still has 19 pins, just like Type A and Type C, but the shape is much more compact.
Feature | Detail |
Pin Count | 19 |
Size | 6.4 mm × 2.8 mm |
Main Use | Small portable electronics |

Type D HDMI connectors give you flexibility. You can share your content anywhere, anytime. If you travel or use portable devices, Type D cables make it easy to connect and display your media.
HDMI Cable Code Compliance
Mandatory Certification Steps
HDMI cables must go through tough tests before being sold. These tests make sure the cables are safe and work well. The first step is lab testing at special HDMI centers. Experts check if the cables follow the newest HDMI rules. They look at things like signal quality and speed. They also test for electromagnetic interference, called EMI. EMI tests make sure your cable does not mess up Wi-Fi or other wireless signals.
Manufacturers have to use special labels on certified cables. Each cable gets a label or a QR code. This shows the cable passed all the tests. You can scan the QR code to see if the cable is real. These labels help you avoid fake or bad cables.
There are also legal rules to follow. Companies must pay to use the HDMI logo and technology. If they skip these steps, they can get in trouble and lose the right to sell HDMI cables. The rules change when new standards come out, like HDMI 2.1 or Ultra96. Companies must update their cables and send them for new tests.
Tip: Always check for certification labels and QR codes on the box. This helps you pick safe and good cables.
Certification
Certification is not just one test. You need to know your cable works every time. Quality checks happen during and after making the cables. Special testers look for problems that might be missed at first. This helps catch mistakes early and keeps the cables good.
Certified cables must meet rules for speed, signal strength, and safety. For example, Ultra High Speed HDMI cables must pass EMI tests. This means your cable will not mess up your wireless devices. Certification also checks if the cable can handle high resolutions and fast refresh rates.
You should buy cables from brands that follow these rules. Brands like Cablink make sure their cables pass all tests and have the right labels. This gives you better performance and peace of mind.
HDCP
HDCP means High-bandwidth Digital Content Protection. You need HDCP to watch protected movies or sports on your devices. HDCP stops people from copying video and audio as it moves through HDMI cables.
When you use an HDMI cable, both your player and your TV must support HDCP. If one does not, you might see a blank screen or an error. Most new HDMI cables and devices support HDCP, but you should always check before buying.
Note: If you want to stream 4K or 8K, make sure your cable and devices support the newest HDCP version. This helps you avoid problems and keeps your content safe.
RoHS & REACH
RoHS and REACH are two important rules that help keep you and the environment safe. When you buy HDMI cables, you should know what these rules mean.
RoHS stands for “Restriction of Hazardous Substances.” This rule says that companies cannot use certain dangerous materials in electronics. For example, RoHS limits the use of lead, mercury, cadmium, and other harmful chemicals. If a cable follows RoHS, it is safer for you and better for the planet.
REACH stands for “Registration, Evaluation, Authorization, and Restriction of Chemicals.” This rule comes from the European Union. It makes companies check and control the chemicals they use in products. REACH helps protect your health and the environment by making sure products do not have unsafe chemicals.
You should look for RoHS and REACH marks on the packaging when you buy HDMI cables. These marks show that the cable meets strict safety rules.
Tip: If you see “RoHS compliant” or “REACH compliant” on the box, you know the cable is safer to use and better for recycling.
Here is a quick table to help you remember:
Compliance | What It Means | Why It Matters |
RoHS | No dangerous metals or chemicals | Safer for you and the planet |
REACH | Controls all chemicals in products | Protects health and environment |
Brands like Cablink make sure their HDMI cables meet RoHS and REACH rules. This means you can trust these cables in your home, school, or office.
CL2 & CL3
CL2 and CL3 are special safety ratings for HDMI cables. You need to know about these if you plan to run cables inside your walls.
CL2 means “Class 2.” A CL2 cable can handle up to 150 volts. It has a special jacket that stops fire from spreading. You can use CL2 cables for most in-wall setups in homes.
CL3 means “Class 3.” A CL3 cable can handle up to 300 volts. It has even stronger fire protection. You should use CL3 cables for bigger jobs, like in-wall wiring in offices or commercial buildings.
If you want to hide your HDMI cables in the wall, always pick cables with a CL2 or CL3 rating. This keeps your home safer and follows building codes.
Note: Never use regular HDMI cables inside walls. They do not have the right fire protection.
Here is a simple checklist for in-wall HDMI cables:
- Look for “CL2” or “CL3” on the cable or box.
- Check your local building codes.
- Choose cables from trusted brands like Cablink.
You keep your setup safe and legal when you use the right cable. Always check for these ratings before you start your installation.
Choosing the Right HDMI Cable – 5 Tips
