How to Connect More HDMI Devices to Your TV

In addition to the number of ports available, HDMI switches can have various features that make them more appealing. While most modern switches will likely reach 4K resolution, you can still find cheaper alternatives that max out at 1080p. In addition to resolution, switches can have different refresh rates, with some only able to reach 30Hz and others reaching 120Hz. This is a matter of preference, but if you want the best picture, you’ll want an 8K/120Hz compatible switch. Other things to consider include the audio or music formats supported, such as Dolby Atmos and Dolby Digital, the availability of HDR, and the version of the HDMI cable (2.1, 2.0, etc.) that the switch can read.

You can also find passive and active HDMI switches that can directly affect the quality of the transmitted image. A passive switch is a simple component that does not require an external power source. It connects to your TV and devices and transmits the received signal. Active switches have an external power source and can boost the signal. For example, if you have an active 4K switch but are transmitting from something that only reaches 1080p, the switch can upscale it for a better image.

Finally, some HDMI switches require you to change inputs with the remote. Others automatically switch based on the device you’re using. So, if you end the night playing PS5 and start the day playing Xbox, the switch can automatically select the output you’re using.
