Yet the bit rate you see quoted will often be the combined total for all three – to get a higher number to impress you with. This is relatively easy if you play the movie from a device with an HDMI output – like a Blu-ray player or media streamer. You will only need to buy a new cable to watch 4K UHD video if you currently have a category 1 HDMI cable. A category 2 ‘high speed’ HDMI cable will support up to 4K/60 UHD video. The most common reason would be that you want to connect your computer or notebook to an external monitor or HDTV – and you will then be able to send video and audio into an HDMI port on your display device.
There are, however, a few products that can serve as BOTH an HDMI Switcher and Splitter, meaning their HDMI ports can serve as either Input or Output. But to keep things simple, it’s usually best to buy a product that fits your specific need. In this article – we’re looking at HDMI Switchers (and one that does both). CEC: consumer electronics control allows you to control several devices connected via HDMI with a single remote – such as volume and power commands.There may be situations where you can’t just use HDMI to connect all your devices. For example, you may have HDMI on one device and a DVI connector on another. Manual Switching with a Remote: You still have to switch between the connected input ports manually, but at least you don’t have to get up from the sofa, as you have an IR remote that controls the switcher. The release version of the HDMI standard – an audio and video interface that allowed the transfer of standard and high-definition video. I do, however, run into the same length hurdle as discussed in this thread. I have my gaming PC and a reasonable 1440p Ultrawide sitting on my desk. I need approx a 10m cable run around the perimeter of the room to reach my TV. Its final resting place is not yet decided, given I haven't figured out how to reliably connect it and get the 4k 120Hz signal I want. Specified a new Enhanced Audio Return Channel (eARC). Allows the transfer of uncompressed and object-based audio from the TV to a home theater system via an existing HDMI connection. eARC also supports a new Auto Lip Sync feature.
Connecting a gaming console to your TV is one of the main reasons people buy an HDMI Switch. However, while there should be no issues with the original PS4, the older XBOX, and most other gaming consoles – the PS4 PRO, PS5 and XBOX Series X do raise some concerns. As the HDMI specification is updated, more video formats are supported. Your hardware must support the HDMI version to use a specific video resolution. Here is a helpful table that compares the differences between optical, HDMI ARC and HDMI eARC connections: Optical, HDMI ARC and HDMI eARC Connection Comparison So, you would convert the connection type from USB to HDMI using the adapter and then use a standard HDMI cable to connect to your display device. Why might you want to do this? To use HDMI ARC, you will often need to enable HDMI CEC on your devices. This allows your two devices to talk to each other and automatically detect when a signal is present. Mainly this works well. However, different brands can sometimes struggle to talk to each other. If you have a problem with this, an optical connection may cause fewer headaches!

Audio: It carries multi-channel surround sound like Dolby Atmos that older connections can’t. HDMI keeps quality high for both your video and audio. But if you can use either, you would usually use HDMI ARC – as it saves you from connecting another cable.
A common problem for some people is they want to show a movie on more than one TV screen – or maybe they have a TV and projector and want to run both simultaneously.Three of the seven separate conductors in an HDMI with Ethernet cable also form an extra twisted pair. HDMI Pin Outs (Type A Connector) Some HDMI switchers come without a separate power supply – instead, they get their power from the HDMI devices you connect (which are usually connected to either the wall outlet or your TV’s USB port).
TMDS: HDMI uses transition-minimized differential signaling (TMDS) to send video, audio and auxiliary data between devices.
HDMI 1.3 added the ability to bitstream HD audio instead. With bitstreaming, the raw HD audio data is sent directly to the amplifier without decoding first. The amplifier then decodes the signal. You might need a new cable for HDMI 2.1, which allows for increased video resolutions of 4K/120p and 8K/60p. An 8K port that supports both versions will be labeled 8K/60AB – whereas an 8K port with only Type B support will be displayed as 8K/60B. What is HDMI CEC? The truth is you are hardly likely to get much oxidization going on in your living room. Or is your TV in the garden?
