HDMI Switch Buying Guide

As with any electronic unit, the most important features you should always consider when buying an HDMI switch can be reduced to their durability, reliability and quality maintenance. However, if you want to get down to the specifications, these are some hallmarks you should look for when purchasing.

  • Ports - Different switchers use a different number of input ports, and what you choose ultimately comes down to the number of devices you plan to ‘switch’ within the same TV or monitor. However, more ports don’t always mean a better experience, as they can be reduced in quality and require more power to run efficiently. So you should carefully read the manufacturer’s specifications on this matter.
  • Compatibility - Having a high-quality TV will only be as good as its matching HDMI switcher. To marvel away at the beauty of 4K watching experience, you need to make sure that both the switcher and the HDMI cable are suitable for transmitting the signals efficiently.
  • Refresh Rate - This feature is less critical to TV watchers and almost indispensable to gamers, and it refers to the number of times a screen will refresh in a minute. We measure this rate in hertz, and its most common distinction includes the 30 and 60 Hz. As you might guess, a 60 Hz unit promotes a better watching experience, but it is also less common and more pricey.
  • Switching Variability (Optional) - Variability with the way you switch between the channels is not essential. Still, it is crucial for those who prefer the comfort of their sofas and beds. Most HDMI switchers use a button switch that’s at the centre of the unit, but some function by remote control. The two types don’t differ highly in price, but because remote-controlled devices have an integrated signal receiver - they usually weigh more and are larger in design.


Q: Does HDMI Switch reduce quality?

A: Typically, an HDMI switch doesn’t reduce quality because all it does is to transmit the material from the main ports into the output ones. However, if you use an HDMI cable that is below the quality standard of the unit, then you might experience a reduction of quality.

Q: Do I need 4K HDMI switch?

A: If you have a TV that supports an Ultra HD or 4K quality, then it’s essential to get a compatible switcher. If you get a standard one, the unit will compress the picture or ruin its quality, resulting in an overall lousy watching experience.

Q: What is HDMI switch used for?

A: We use an HDMI switch for linking several input sources into one output display unit that is usually a monitor or a TV. HDMI switches are perfect for getting rid of the hassles that come with plugging and unplugging different devices from the same TV and simplifying the switch between them.

Q: Do HDMI switches cause lag?

A: As long as you get an excellent switcher that has an actively functioning circuit, you won’t experience lag. However, note that external factors like compatibility of the devices or inputs quality can also cause that lag.
