Choosing the Right Cables for Your Setup
Having the right cables is crucial for connecting all your peripherals and getting the best performance out of your devices. With so many cable types and variations, it can get confusing to figure out which ones you need. This guide will help you understand the key differences and select the right cables for your specific setup.
Connecting and Powering Peripherals
The most common cables used to connect peripherals are:
- USB - For devices like printers, external hard drives, webcams etc. USB 3.0 offers faster data transfer speeds than USB 2.0.
- HDMI - Primarily used for HD video and audio from devices like Blu-ray players, gaming consoles to TVs and monitors. HDMI cables come in different categories depending on bandwidth support.
- DisplayPort - Used to connect PCs and laptops to external displays. Supports higher resolutions and refresh rates than HDMI.
- Thunderbolt - For connecting peripherals at high speeds. Thunderbolt 3 uses USB Type-C connector and offers data transfer up to 40Gbps.
For powering devices, USB cables are the most common. However, some devices may need higher power delivery supported by USB PD (Power Delivery) cables. Apple products use USB-C cables for both power and data.
Video vs Data Cables
HDMI and DisplayPort are primarily used for video signals. USB and Thunderbolt cables can carry both video and data signals. For best video quality over long distances, use active HDMI cables. They have built-in signal boosters to prevent signal degradation.
Cable Length and Performance
Longer cables typically have higher resistance, which reduces signal quality and data transfer speeds. The max length for common cables are:
| Cable Type | Max Length |
|---|---|
| HDMI | 15 feet |
| DisplayPort | 6 feet |
| USB 2.0 | 16 feet |
| USB 3.0 | 9 feet |
| Thunderbolt 3 | 50 feet |
For longer runs, use active/repeater cables or signal boosters. Fiber optic cables can transmit data up to 300 feet without signal loss.
Quality and Durability
Buying quality cables from reputable brands ensures durability and reliability. Some features to look for include:
- Gold-plated connectors resist corrosion.
- Reinforced connectors and strain relief for flexing.
- Proper shielding reduces interference.
- Oxygen-free copper conductors for optimal signal flow.
Avoid cheap cables that may deteriorate quickly or cause connection problems. Spending a few extra dollars on quality cables saves you headaches down the road.
By understanding your connectivity requirements, cable capabilities, and choosing cables optimized for your setup, you can avoid performance bottlenecks and get the most out of your devices.

Connecting and Powering Peripherals
Connecting peripherals to your computer allows you to expand its capabilities with additional devices like printers, scanners, external storage, and more. Here's a guide on cables and ports needed to hook up common peripherals.
USB
USB (Universal Serial Bus) is the most common port used to connect peripherals. There are several types:
- USB 2.0 - Standard USB port found on computers. Provides up to 480Mbps data transfer speed.
- USB 3.0/3.1 Gen 1 - Also called SuperSpeed USB, it offers up to 5Gbps transfer rates and is backwards compatible with USB 2.0.
- USB 3.1 Gen 2 - Referred to as SuperSpeed USB 10Gbps, it can transfer data up to 10Gbps and is becoming more common on new computers.
- USB-C - Uses a smaller reversible connector, but supports the same USB 3.x transfer speeds. USB-C ports can also provide power for charging devices.
Almost all peripherals like keyboards, mice, flash drives, and external storage connect via USB. Many printers, scanners and webcams also use USB. For best performance, connect USB 3.0 devices to USB 3.0 ports.
Display Interfaces
External displays require high-bandwidth, high-resolution interfaces like:
- HDMI - Primarily used for HDTVs and supports up to 4K resolution.
- DisplayPort - Newer interface designed for high resolution displays up to 8K. Common on new monitors and laptops.
- DVI - Older standard supporting up to 1080p used on older LCD monitors.
- Thunderbolt - Supports dual 4K displays or a single 5K display over a USB-C connector.
Network Connections
For a wired network connection, use an Ethernet cable to connect to a router or switch. Ethernet provides faster and more reliable connectivity compared to Wi-Fi for stationary devices.
Powering Peripherals
Small peripherals may get enough power directly from USB ports on your computer. But larger devices like external hard drives require dedicated power adapters to function. Some options are:
- AC power adapter - Connects to a wall outlet to provide sustained power.
- USB power adapter - Can power smaller peripherals using a USB port for power input.
- USB-C power delivery - USB-C ports can supply power up to 100 watts for charging and powering devices.
With the right cables and ports, you can easily add many types of peripherals to enhance your computer system.
Video vs Data Cables
Cables used for connecting devices can be categorized as either video cables or data cables based on their primary purpose.
Video Cables
Video cables are designed for carrying high-bandwidth video signals from sources like Blu-ray players, gaming consoles, cameras to displays or TVs. Common video cable types are:
- HDMI - Supports uncompressed digital video and audio. Used to connect Blu-ray players, gaming consoles to HDTVs. Latest version supports 8K at 60Hz.
- DisplayPort - Newer standard by VESA used primarily between computers and monitors. Supports up to 8K resolution at 60Hz.
- DVI - Digital video interface directs uncompressed signal. Used for computer monitors requiring high bandwidth. Does not carry audio.
- VGA - Analog signal cable for older computer monitors. Limited to 1080p resolution.
These cables utilize dedicated connections and high gauge wires to maintain signal integrity across the length of the cable at high video bandwidths. For instance, an HDMI cable has 19 pins and uses copper wiring to transmit 10.2Gbps for 4K 60Hz video.
Data Cables
Data cables are used for general data transfer between computers, hard drives and other peripherals. Some common data cables are:
- USB - Universal Serial Bus is the most ubiquitous connector for peripherals. USB 2.0, 3.0 and USB-C support up to 480Mbps, 5Gbps and 10Gbps speeds respectively.
- Thunderbolt - Very high speed interface that can daisy chain multiple devices. Thunderbolt 3 uses USB-C connectors and offers 40Gbps throughput.
- Ethernet - Used for wired network and internet connections. Cat 5e and Cat 6 cables support 1Gbps and 10Gbps network speeds.
Data cables employ differential signaling and shielding techniques to reduce noise and interference during data transfer. For example, USB 3.0 cables have twin-axial shielded balanced pairs for receiving and transmitting data.
Hybrid Cables
Some cable standards support both video and data over the same connection. For instance:
- HDMI carries uncompressed digital video as well as multichannel digital audio.
- DisplayPort supports video, audio, USB and other data.
- Thunderbolt transmits video, data and power together.
USB Type-C is the most versatile modern connector. It can transmit up to 10Gbps data, 4K 60Hz video, audio and up to 100W power delivery over a reversible plug.
Understanding the core capabilities and limitations of video, data and hybrid cables will help you choose the right cable to connect devices for optimal performance.
