What HDMI Cable Should I Buy?

Walking through the electronics store or shopping online, you’ll see many different HDMI cables. Some are labeled “Standard,” others say “High Speed” or even “Ultra High Speed.” The prices and packaging can be confusing. If you’ve ever wondered, “What HDMI cable should I buy?”, you’re not alone! Let’s break it down simply, so you can pick the perfect cable for your TV, computer, or game system without any stress.

What Is an HDMI Cable?

An HDMI cable lets you send both video and sound through one simple cord. You use it to connect things like TVs, monitors, streaming boxes, game consoles, and even some computers or projectors. One end goes into your device, the other into your screen. Most of the time, you just need to make sure the ends fit the ports you have. Sometimes, if the plugs don’t match, you use an HDMI adaptor.

Types of HDMI Cables—What Do They Mean?

Not all HDMI cables are the same. Each type is made for different kinds of devices and picture quality. Here are the main types you’ll find:

• Standard HDMI cable: Good for older TVs, DVD players, and basic setups. These work fine for 720p or 1080i signals (not quite full HD).

• High speed HDMI cable: This is the most popular type people use today. It works for full HD (1080p), 4K TVs, Blu-ray, game consoles, and streaming boxes. It supports higher resolutions and extra features, like 3D video and faster refresh rates.

• Ultra high speed HDMI cable: These are for new TVs and monitors that show 8K or faster 4K at 120Hz. They support extra features found on the latest devices, like super-clear gaming, advanced sound channels, and the newest color effects.

If you want to future-proof your entertainment system, it's a good idea to get at least a high speed HDMI cable. You only need ultra high speed if your TV or gaming setup is brand new and supports fancy features like 8K video, fast frame rates, or advanced sound systems.

Connector Types—Will the Cable Fit?

HDMI comes in different sizes and shapes. Here are the main ones you’ll see:

• Standard HDMI (Type A): This is the big plug found on most TVs, monitors, and game consoles.

• Mini HDMI (Type C): Smaller plug for cameras, some tablets, or tiny computers.

• Micro HDMI (Type D): Very small, for phones or special gadgets.

Check what kind of port your device has. An HDMI adaptor helps you switch between sizes if needed. Always make sure the cable or adaptor fits both ends before you buy.

The Exact Answer: What HDMI Cable Should I Buy?

The best choice for most people is a high speed HDMI cable. It supports HD, 4K, and even some newer features. If you have a new 4K or 8K TV, a game console like PlayStation 5 or Xbox Series X, or you watch a lot of movies and sports in the highest quality, you might want an ultra high speed HDMI cable for the best results. For older devices, a standard cable is enough.

Always make sure the connectors on the cable match your devices, or use an HDMI adaptor if you need to connect different sizes.

Do I Need a Fancy or Expensive HDMI Cable?

You don’t need the priciest cable on the shelf. Even basic brand-name high speed HDMI cables will give you great video and sound. Expensive cables don’t mean better quality for most homes. Just make sure the cable you choose is strong, certified, and long enough for your setup.

How Long Should My HDMI Cable Be?

Pick a cable that’s only as long as you need—shorter is better. Signals can get weaker through very long cables, especially older or basic ones. For runs shorter than 6 feet (about 2 meters), almost any high speed HDMI cable is fine.

If you need to go longer—across a room or behind a wall—choose an “active HDMI cable” or fiber-optic HDMI cable, which are built to keep signals strong over long distances. For short lengths, regular high speed cables do the job well.

What About HDMI Adaptors and Special Setups?

If your device doesn’t have a regular HDMI port, get an HDMI adaptor. These let you connect from USB-C, Mini HDMI, DisplayPort, or other special plugs to your TV or monitor’s HDMI port. Adaptors are easy to use—just plug them in, then connect your regular HDMI cable.

Use adaptors carefully and try to keep the connection direct for the best results. If possible, pick a high speed HDMI cable and matching adaptor that are both built for the picture quality you want.

What Makes a Good HDMI Cable?

Look for these signs of a good HDMI cable:

• Labeled “High Speed,” “Premium,” or “Ultra High Speed”

• Matches the length you need (shorter if possible for the best signal)

• Right size for your devices (or use the right HDMI adaptor)

• Sturdy build with strong plugs and no loose ends

• Certified for the features you want—like 4K, 8K, high refresh rate, or advanced sound

How Can I Tell If My Cable Is Working?

After you connect your cable, check the screen. If the picture is sharp, colors are bright, and the sound is clear, your HDMI cable is working great. If you see dots, stripes, flickering, or missing sound, the cable may be broken, too long, or not made for your TV’s high quality needs. Simply trying another cable or using an adaptor may fix the issue.
