FAQ: Computer Cables and Adapters
What’s the difference between USB 2.0 and USB 3.0?
USB 3.0 (and above) offers much faster data speeds (up to 5 Gbps vs. 480 Mbps) and is ideal for external hard drives, SSDs, and high-speed peripherals.
Can I use a USB-C to HDMI adapter with any laptop?
Only if your laptop’s USB-C port supports video output (DisplayPort Alt Mode). Not all USB-C ports support this; check your device specs.
Are all HDMI cables the same?
No, HDMI 1.4 supports 1080p and some 4K, while HDMI 2.0/2.1 supports 4K at higher refresh rates and even 8K.
Can I connect a DVI monitor to HDMI?
Yes, with a DVI to HDMI adapter or cable. However, DVI does not carry audio, so you’ll need a separate cable for sound.
Do I need a special Ethernet cable for gaming?
A Cat6 cable is ideal; it supports high speeds and reduces interference for stable performance.
What’s the best way to expand ports on a laptop with only USB-C?
Use a USB-C hub or docking station that includes HDMI, USB-A, SD card readers, and Ethernet, ideal for ultrabooks and MacBooks.
Can I charge a laptop with a USB-C cable?
Only if both the cable and power source support USB-C Power Delivery (PD) and match the required wattage for your laptop.
