HDMI 2.0, released in 2013, increased the bandwidth to 18 Gbps, supporting 4K resolution at 60 Hz. HDMI 2.1, released in 2017, further increased the bandwidth to 48 Gbps, supporting 8K resolution at 60 Hz and variable refresh rate (VRR) technology.
Cable Quality and Construction
While HDMI versions are essential, the quality and construction of the cable itself also play a significant role in determining its performance.
Copper vs. Silver-Tipped Cables
HDMI cables can be made with either copper or silver-tipped conductors. Copper is the most common material used, but silver-tipped cables are considered to be of higher quality. Silver has a higher conductivity than copper, which can result in a more stable signal.
Shielding and Insulation
A well-shielded and insulated cable can help reduce electromagnetic interference (EMI) and radio-frequency interference (RFI). Look for cables with thick, high-quality insulation and shielding to minimize signal degradation.
Connectors and Build Quality
The connectors and build quality of the cable can also impact its performance. Look for cables with gold-plated connectors, which can help reduce corrosion and improve signal quality.
Active vs. Passive Cables
Another critical factor to consider is whether the cable is active or passive.
Passive Cables
Passive cables rely on the signal strength from the source device to transmit the signal to the display device. These cables are suitable for shorter distances (up to 10 meters) and lower resolutions.
Active Cables
Active cables, on the other hand, have built-in amplifiers or repeaters that boost the signal, allowing for longer distances (up to 30 meters) and higher resolutions. Active cables are more expensive than passive cables but offer better performance.
What to Look for When Buying an HDMI Cable
When purchasing an HDMI cable, consider the following factors:
Length and Distance
Choose a cable that is long enough to reach from your source device to your display device, but not so long that it introduces signal degradation.
