"DIY Old Driver Series" is now in its fifteenth episode. Continuing from the twelfth issue, this time we're diving into how to choose the right HDMI cable. The old drivers are back on the road again—grab the armrests and get ready for a smooth ride!
[PConline Talk] When using high-definition or even 4K playback platforms, selecting the right HDMI cable becomes essential. Some users may wonder: How do I choose the best HDMI cable? Don’t worry—we’ll break it down step by step so you can become an expert in no time.

**Step 1: Determine the HDMI Interface Version**
HDMI cables come in various versions, such as 1.3, 1.4, and 2.0. The black version usually represents 1.4 or 1.3, while the blue one is for 2.0. In our previous episode, we explained that different HDMI versions support varying bandwidths and technologies. To ensure compatibility, your HDMI cable should be at least the same or higher version than your device’s interface. For example, using a 1.4 cable with a 2.0 port won't support 4K@60Hz, but a 2.0 cable with a 1.4 port will work just fine, though it might cost more.
**Step 2: Check for Certification Marks**
Look for HDMI or Sinplay certification on the packaging. A quality cable often carries both certifications, ensuring better reliability and performance.
**Step 3: Inspect the Connector**
Gold-plated connectors are a good sign. They offer better conductivity, corrosion resistance, and durability. Most high-quality HDMI cables use 24K gold plating. However, the most important part is the PIN pin inside the connector. These are typically made of tin bronze, then plated with nickel and gold for enhanced performance.
**Step 4: Examine the Core Material and Manufacturing Process**
Traditional HDMI cables use copper or silver-coated copper as the core material. Copper ensures better signal transmission and less interference. You can test this by gently bending the cable—if it feels soft and flexible, it's likely copper. If it snaps easily, it might be made of cheaper materials.
Now, there's a new trend: fiber-optic HDMI cables. These use optical fibers instead of copper, allowing for faster data transfer over longer distances without signal loss. While they’re ideal for professional setups, for everyday use, a standard copper-core HDMI cable is more than sufficient.
**Step 5: Avoid Too Thin Cables**
Thicker cables don’t always mean better. Some third-party brands may make their cables look thicker by adding unnecessary fillers. Always go for reputable brands. Even for well-known manufacturers, if the cable is too thin, it could mean poor shielding or a weak core, which affects signal quality.
**Understanding AWG (American Wire Gauge)**
AWG measures the thickness of the wire. The lower the AWG number, the thicker the wire. Thicker wires can carry more current and support longer distances. Here's a general guideline:
- 30 AWG: 5–8 meters
- 28 AWG: 12–15 meters
- 26 AWG: 18–20 meters
- 24 AWG: 20–25 meters
So, when choosing an HDMI cable, the smaller the AWG value, the better the performance—especially for longer runs.
**Conclusion**
Purchasing an HDMI cable doesn’t always mean spending more. As long as you match the cable’s version, transmission capacity (like AWG and core material), and quality (certifications, connectors, and brand), you’ll end up with a great product. Understanding these factors helps you make an informed decision rather than just going for the price tag.
After two years of driving with the old driver, you now know the difference between HDMI versions and how to pick the right cable. You’ve officially become an HDMI expert! Now it's your turn to shine—happy driving!
