While both HDMI splitters and switches deal with HDMI signals, they serve different purposes. An HDMI splitter duplicates a single HDMI signal to multiple displays, ideal for scenarios where you want to mirror content across multiple screens. On the other hand, an HDMI switch allows you to connect multiple HDMI sources to a single display, enabling you to switch between different input sources seamlessly.

To distribute audio and video signals to different rooms in your house, you can use an HDMI switch to consolidate multiple HDMI sources into a single output. Then, you can connect that output to an HDMI splitter to duplicate the signal to multiple displays in different rooms. By combining an HDMI switch and splitter, you can enjoy synchronized audio and video playback throughout your home, making it ideal for multi-room entertainment setups.

Yes, you can use an HDMI splitter and an HDMI switch together to achieve specific configurations in your home cinema setup. For example, you could connect multiple HDMI sources (such as gaming consoles, Blu-ray players, and streaming devices) to an HDMI switch to consolidate them into a single input on your TV or display. Then, you could use an HDMI splitter to duplicate that signal to multiple displays, allowing you to enjoy the same content on different screens simultaneously.

While it's technically possible to daisy-chain HDMI switches and splitters together, it's not typically recommended due to potential signal degradation and compatibility issues. Instead, consider using a single high-quality HDMI switch or splitter with multiple inputs or outputs to accommodate your devices and displays.
