Learn the key differences between HDMI switches and HDMI splitters. Discover how each device works, when to use them, and how they can improve your HDMI connectivity setup.
Connecting with HDMI ports can sometimes prove to be rather complex, particularly in a situation in which a participant experiences a larger number of devices than inputs a single TV/monitor possesses. With games consoles, computers, and streaming devices, the number of HDMI sources can significantly outgrow the HDMI inputs on the display. This is where HDMI switches and splitters come in handy. These devices can solve many connectivity problems, but they are not the same. It is very important to distinguish between them if you have to select the most appropriate for your configuration.
What’s an HDMI Switch?
An HDMI switch is a tool that functions to consolidate several image sources – gaming consoles, Blu-ray players, or computers – into a single HDMI port on your television or monitor. Often, it is beneficial when you have more HDMI gadget interfaces in your home than HDMI slots to connect them to your display. Most of today’s TVs and monitors come with multiple HDMI inputs even on entry level devices but sometimes more connections are required. This is where an HDMI switch comes in handy.
It’s like having a traffic signal for your HDMI flow. For example, where the users have many devices, such as a PlayStation, a laptop, and a streaming device, one will be able to connect all to the HDMI switch. From there, the switch allows us to choose which device outputs its signal to the screen at any given time. Some of the HDMI switches include male connectors, while others compel you to connect the HDMI cables from devices directly.
One of the benefits of an HDMI switch is that it eliminates the need to connect or disconnect cables frequently. It helps to avoid the use of the HDMI ports present, as well as the devices you use to make the connections sparingly, in addition to cutting out time and inconvenience. Also, many of the latest HDMI switches have compatibility with high-definition content, including 4k and even 8k, thus making your video quality improve when switching between the different devices.
What’s an HDMI Splitter?
Whereas the HDMI switcher combines the outputs of multiple sources into one output port, the HDMI splitter splits the input-output of the display port into two or more outputs. What happens is it receives from one source, let’s say a cable box or a computer, and sends this same picture to several monitors. This is advantageous if you are looking to show some content on several monitors or in this case on TVs for instance in outlets, meetings, or even at home when setting up for multi-screen gaming.
However, there’s a catch. In the case when the image is divided and created on several screens, the signal quality may deteriorate, especially with a passive splitter. In the case where we are using the splitter to extend content across more than two screens, then we would need to use a powered splitter to realize adequate signal. This helps avoid one of the screens receiving an unstable picture while the other is receiving a clear picture.
Two last points refer to HDMI splitters copying the screen without extending it in any way. If you want different content on each display screen, you will need to find a way around it because splitters only allow the same image viewable by each of the connected outputs.
Can I Extend My Desktop with an HDMI Splitter?
No, HDMI splitters don’t work this way, as they are engineered to display the same picture to more than one screen. You will have to use other tools If you need to add more screens to your desktop, for instance, when optimizing your work with several monitors. Some of the laptops and desktops you find on the market have features such as Thunderbolt or DisplayPort outputs, whereby you can connect multiple monitors using adapters. There are also single units here that have the feature to extend displays, and for that, we would want to look at possible performance problems like latency, especially when it comes to games.
How Are HDMI Switches Different from KVM Switches?
It is perfect to consider HDMI switches and KVM switches look almost similar at first glance or even look like a single product because they both manage to connect multiple devices to a single display. However, a KVM switch does much more than just switch the HDMI input and output of the computer or server. The letters KVM, the abbreviation for ‘Keyboard, Video, and Mouse,’ are the common names of these devices, which not only control the video output but also allow for a shared Keyboard and Mouse between several computers.
KVM switches are usually applied where managing many computers is crucial, including data centers and other productiveness zones. Most KVM Switches offer backward compatibility with older video standards like VGA or DVI, but most KVM Switches nowadays have HDMI interface ports. Sometimes, if we have the KVM switch, it can also perform the duty of an HDMI switch. However, this would seem to be excessive if you do not need to swap between multiple computers using one keyboard and mouse; that is because most conventional KVM switches are even pricier than standard HDMI switches.
Choosing Between an HDMI Switch and a Splitter
The difference between an HDMI switch and an HDMI splitter basically depends on whether one has more image inputs or more outputs. In essence, if one owns several undesirable devices, but only a single screen or projector, then the answer is an HDMI switch. If we want to cast the output to multiple screens, then the use of an HDMI splitter is appropriate.
However, it must be remembered that while these devices fall under the same general category, they have diverse functions. Identifying your needs, whether it be for more input or more output, will prevent you from getting the wrong product.
Conclusion
Both HDMI switches and splitters offer useful approaches to HDMI connection issues, yet they are very distinct devices. Recall that the major difference between them is that monitors are designed with productivity in mind while displays are generally more focused on entertainment; knowing these differences allows one to make better choices as to what electronic equipment to use when setting up home theaters, office workspaces, or any other situation where one needs to control multiple electronics and screens. When the job is switching between multiple consoles, for example, an HDMI switch is needed, or when the same image has to be displayed on multiple screens, a splitter is needed, and we know which one is right for the task.
