Introduction
HDMI 2.2 is now part of the display conversation because it raises the ceiling for future video bandwidth, resolution, refresh rate, and AV synchronization. For people who follow gaming monitors, TVs, graphics cards, and professional AV systems, it is a standard worth watching.
But for someone building a real desk today, the harder question is more practical:
Should you wait for an HDMI 2.2 KVM, or buy an HDMI 2.1 KVM now?
The answer depends less on the version number and more on your current devices. If your setup includes a PS5, Xbox Series X, gaming PC, HDMI 2.1 monitor, OLED gaming TV, MacBook, or work laptop, your immediate needs are probably still centered on HDMI 2.1: 4K 120Hz, 4K 144Hz, 4K 240Hz, 8K 60Hz, HDR, VRR, ALLM, stable EDID handling, and USB peripheral switching.
That is why a TESmart HDMI 2.1 KVM remains a realistic choice for many gaming, creator, and hybrid work desks. We design HDMI KVM solutions for users who need a stable multi-device desk today, not only a future specification on paper.
What HDMI 2.2 Actually Changes
HDMI 2.2 increases the technical headroom of the HDMI ecosystem. The HDMI Forum states that HDMI 2.2 supports up to 96Gbps bandwidth with next-generation HDMI Fixed Rate Link technology, including support for high-end formats such as uncompressed 8K60 and 4K240 with full chroma at 10-bit and 12-bit color. It also introduces support for higher-resolution formats such as 12K@120 and 16K@60 in the specification.
Another important addition is the Ultra96 HDMI Cable. HDMI 2.2 uses the Ultra96 name to indicate products supporting 64Gbps, 80Gbps, or 96Gbps bandwidth, and the new Ultra96 HDMI Cable is designed to support the full range of HDMI 2.2 applications.
HDMI 2.2 also adds Latency Indication Protocol, or LIP. This is especially relevant to multi-hop AV systems, such as setups that pass through receivers, soundbars, or other AV equipment, where audio and video synchronization can become harder to manage.
These are meaningful changes. HDMI 2.2 is not just a label change. It expands what future HDMI devices can do. The key point is that a stronger standard does not instantly make every monitor, TV, GPU, console, cable, and KVM on the market HDMI 2.2-ready.
HDMI 2.1 vs HDMI 2.2: The Practical Difference
For most users, the simplest way to understand HDMI 2.1 vs HDMI 2.2 is this:
HDMI 2.1 is the current high-performance desktop standard. HDMI 2.2 is the next bandwidth step for future displays and AV systems.
HDMI 2.1 brought up to 48Gbps bandwidth, 4K120, 8K60, Dynamic HDR, and Ultra High Speed HDMI Cable support. These features are already relevant to many gaming PCs, PS5 and Xbox setups, high-refresh gaming monitors, and modern TVs.
HDMI 2.2 doubles the maximum bandwidth ceiling to 96Gbps and prepares the HDMI ecosystem for more demanding combinations of resolution, refresh rate, chroma, and bit depth. It is important for future 4K ultra-high-refresh, 8K high-refresh, 10K, 12K, and 16K workflows. But those use cases require matching source devices, displays, cables, and intermediary hardware.
This is where many buyers get confused. A port shape does not guarantee full protocol capability. An HDMI cable does not become “HDMI 2.2” just because it has the same connector shape. A display advertised with a future-facing feature may still have limited bandwidth on some ports. A KVM can only preserve the signal that the complete chain is designed to support.
Why Most High-End Desks Still Depend on HDMI 2.1
Most current high-end desks are not waiting for 16K. They are trying to make today’s hardware work correctly.
A gaming user may want to switch between a PS5, Xbox Series X, and Windows gaming PC on the same OLED TV or gaming monitor. A creator may want a gaming PC and a work laptop to share one or two HDMI displays, a keyboard, a mouse, a headset, a capture card, and external storage. A Mac/PC user may need one desk for a MacBook and a Windows workstation without reconnecting cables every day.
In these setups, the real requirements are usually:
4K 120Hz for consoles and TVs
4K 144Hz or 4K 240Hz for high-refresh monitors, depending on connected devices, cables, display, and KVM specifications
8K 60Hz for users with compatible displays and source devices
VRR, ALLM, HDR, and audio behavior that depends on the entire HDMI chain
Stable EDID communication so systems do not repeatedly forget the display
USB keyboard, mouse, controller, webcam, DAC, headset, or storage switching
Sony’s own support documentation notes that PS5 consoles support HDMI 2.1 and 4K 120Hz output, while also reminding users that the TV, cable, HDMI port, and intermediary equipment can affect whether 4K 120Hz works correctly. :contentReference[oaicite:4]{index=4}
That point matters for KVM buyers. A 4K 120Hz KVM or 4K 240Hz KVM is not only about one box in the middle. The source device, GPU settings, console settings, HDMI cable, monitor input, TV enhanced mode, EDID handling, and KVM specifications all need to match.
Why the HDMI 2.2 Ecosystem Will Take Time
Waiting for HDMI 2.2 can make sense for users who rebuild their entire display chain around future devices. But a full HDMI 2.2 desk is not just one purchase.
To benefit from HDMI 2.2 bandwidth, a user would need source devices that output HDMI 2.2 at the required bandwidth, displays that accept it, Ultra96-certified cables where needed, and any device in the middle—including receivers, soundbars, capture devices, splitters, or KVM switches—to support the required signal path.
That ecosystem takes time for several reasons:
Monitor and TV makers need to adopt HDMI 2.2 inputs.
GPU and console makers need to include HDMI 2.2 outputs.
Cable makers need certified Ultra96 products across useful lengths.
KVM manufacturers need chipsets, validation time, firmware tuning, and real-world compatibility testing.
Users need clear product labeling, because “HDMI” alone does not tell you bandwidth, refresh rate, VRR, HDR, DSC, or audio behavior.
The HDMI Forum states that Ultra96 HDMI Cable certification requires each model length to be tested and certified, similar to the Ultra High Speed HDMI Cable program. That is useful for reliability, but it also means the full ecosystem does not become mature overnight.
For users already owning HDMI 2.1 monitors, PS5, Xbox Series X, RTX or AMD gaming PCs, MacBooks, and work laptops, waiting for a future HDMI 2.2 KVM may delay a desk upgrade without solving today’s switching problems.
HDMI Switch, USB-C Dock, or HDMI 2.1 KVM?
A common mistake is treating every switching device as the same thing. They solve different problems.
Basic HDMI Switch
A basic HDMI switch changes which video source appears on a display. It is useful when you only need to switch video, such as choosing between a console and a streaming device on a TV.
It usually does not manage keyboard, mouse, USB peripherals, headset, webcam, or storage switching. It also may not preserve EDID behavior as well as a KVM designed for computer workflows.
USB-C Dock
A USB-C dock expands one laptop. It can add display outputs, USB ports, Ethernet, audio, and power delivery to a single computer.
That does not make it a multi-computer switching system. A dock is helpful when one laptop needs more ports. It is not the same as a gaming PC and console KVM, and it does not normally switch a full desk between multiple computers.
Standard KVM
A KVM switches keyboard, video, and mouse control between computers. A standard KVM may be enough for office resolutions such as 1080p or 4K60, depending on the model.
For high-refresh HDMI gaming and creator setups, however, a basic KVM can become the bottleneck if it does not support the required bandwidth, EDID behavior, or USB needs.
HDMI 2.1 KVM
An HDMI 2.1 KVM is designed for users who want high-bandwidth HDMI video and USB control switching in one desk setup. This is the category that matters for many PS5, Xbox, gaming PC, Mac/PC hybrid, and high-refresh monitor users.
For example, an HDMI 2.1 switch for PS5 and PC may only change the video signal. A gaming PC and console KVM can also help manage keyboard, mouse, USB peripherals, and display control in the same workflow.
Comparison Table: Wait, Buy, Switch, Dock, or KVM?
| Option | Best Fit | Main Limitation | Practical Recommendation |
|---|---|---|---|
| Waiting for HDMI 2.2 | Users planning a future desk around HDMI 2.2 displays, GPUs, AV receivers, certified Ultra96 cables, and future HDMI 2.2 KVM hardware. | The ecosystem still needs time across displays, source devices, cables, KVMs, and real-world compatibility testing. | Worth watching, but not necessary for most current 4K 120Hz, 4K 144Hz, 4K 240Hz, or 8K 60Hz HDMI 2.1 setups. |
| Buying an HDMI 2.1 KVM now | Users with PS5, Xbox Series X, gaming PC, MacBook, or work laptop setups that need shared displays, keyboard, mouse, and USB peripherals. | Performance depends on connected devices, cables, display inputs, KVM specifications, and enabled display settings. | The most realistic option for many high-end desks built around today’s HDMI 2.1 hardware. |
| Basic HDMI switch | Simple video-only switching between HDMI sources, such as a console and media player. | Does not manage keyboard, mouse, USB peripherals, or full computer control. | Use it only when video switching is enough. Do not treat it as a KVM replacement. |
| USB-C dock | Expanding one laptop with extra ports, display outputs, Ethernet, USB, or charging. | Usually designed for one computer, not for switching a full desk between multiple systems. | Choose a dock when your problem is port expansion. Choose a KVM when your problem is multi-device control switching. |
| TESmart HDMI 2.1 KVM solution | High-refresh HDMI desks with multiple computers or consoles sharing displays, keyboard, mouse, audio, and USB peripherals. | Users still need to verify resolution, refresh rate, VRR, HDR, EDID, cable, and device compatibility for their exact setup. | A practical path for current HDMI 2.1 gaming, creator, workstation, and hybrid office environments. |
Where a TESmart HDMI 2.1 KVM Fits
A TESmart HDMI KVM is not only a video selector. It is intended to sit at the center of a desk where multiple devices need to share display output and USB control.
This matters when your desk includes:
A PS5 or Xbox Series X and a Windows gaming PC
A gaming PC and a work laptop
A MacBook and a Windows workstation
Two computers sharing one or two high-refresh HDMI monitors
A keyboard, mouse, USB headset, webcam, controller, DAC, or external storage that should follow the active computer
For a two-computer dual-monitor HDMI desk, a model such as TESmart HKS202-M24 or another HKS series HDMI KVM can make sense when the number of computers, number of displays, resolution target, refresh rate target, and USB peripheral needs match the product specifications.
The important point is not to buy by version number alone. A good HDMI KVM for gaming should be selected around the complete signal path:
Can each computer output the required HDMI signal?
Does the monitor or TV support that mode on the selected HDMI input?
Are certified Ultra High Speed HDMI cables being used for HDMI 2.1 bandwidth needs?
Does the KVM support the resolution and refresh rate you expect?
Do you need EDID emulation to reduce display re-detection, window movement, or black-screen wait time?
Do your USB devices need USB 2.0, USB 3.0, audio, or dedicated keyboard/mouse ports?
For users who already own HDMI 2.1 devices, an HDMI 2.1 KVM can solve a real problem today: switching the desk, not just chasing a future standard.
What to Check Before Buying
1. Confirm the Resolution and Refresh Rate You Actually Use
Do not start with “HDMI 2.1” or “HDMI 2.2” as a label. Start with the target format:
4K 120Hz for console gaming and OLED TVs
4K 144Hz for gaming monitors
4K 240Hz for high-end competitive displays, depending on GPU, monitor, cable, and KVM specifications
8K 60Hz for compatible high-resolution displays
Then check whether every part of the chain supports that target.
2. Treat VRR, HDR, and ALLM as Full-Chain Features
VRR, HDR, ALLM, DSC, and advanced audio behavior depend on more than one device. The source, cable, KVM, display, and settings all matter.
When a product page lists support for advanced features, check the exact conditions. Some features may depend on the connected devices, cables, display, firmware, and KVM specifications.
3. Pay Attention to EDID
EDID tells the source device what the display can do. In a multi-computer desk, unstable EDID behavior can lead to resolution changes, window rearrangement, black screens, or long re-detection times after switching.
A KVM designed for desktop workflows should help manage display identity more predictably than a basic video switch.
4. Do Not Ignore Cables
For HDMI 2.1 workflows, use certified Ultra High Speed HDMI cables where high bandwidth is required. For HDMI 2.2 workflows in the future, Ultra96 cable certification will matter for full HDMI 2.2 bandwidth use.
Shorter, certified cables are often easier to stabilize than long, uncertified cables, especially at high resolution and high refresh rate.
5. Be Careful with MacBook and Dock Layers
MacBook setups often involve USB-C, HDMI adapters, docks, or hubs. Each extra conversion layer can affect video negotiation and USB behavior.
If you are building a Mac/PC mixed desk, confirm whether the Mac can output the required resolution and refresh rate through its HDMI port, USB-C to HDMI adapter, or dock before adding a KVM into the chain.
FAQ
Is HDMI 2.2 better than HDMI 2.1?
Yes, HDMI 2.2 has a higher maximum bandwidth ceiling and supports more demanding future video formats. But “better” does not automatically mean necessary for your current desk. HDMI 2.1 still covers many real-world high-end needs, including 4K120 and 8K60, depending on the connected hardware.
Should I wait for an HDMI 2.2 KVM?
Wait if you are planning a future system where every major device will support HDMI 2.2, including the source, display, cables, and KVM. If your current setup is based on PS5, Xbox Series X, HDMI 2.1 gaming monitors, gaming TVs, or current GPUs, an HDMI 2.1 KVM is usually more practical.
Will an HDMI 2.1 KVM become obsolete soon?
Not for most current users. HDMI 2.1 remains relevant for 4K 120Hz, 4K 144Hz, 4K 240Hz, 8K 60Hz, HDR, VRR, ALLM, and high-performance gaming or workstation desks, depending on product specifications and the full connected chain.
Can an HDMI 2.1 KVM support 4K 240Hz?
It depends on the KVM model, the source device, the display, cable quality, color format, bit depth, compression behavior, and settings. Do not assume every HDMI 2.1 KVM supports every 4K 240Hz scenario. Always check the exact product specification and your device chain.
Is a basic HDMI switch enough for PS5 and PC?
A basic HDMI switch may be enough if you only need to switch video. If you want to share a keyboard, mouse, USB headset, webcam, controller, or other USB peripherals between a PS5, PC, MacBook, or work laptop, a KVM is the more appropriate category.
Is a USB-C dock the same as a KVM?
No. A USB-C dock expands one computer. A KVM switches control between multiple computers. Some desks use both, but they solve different problems.
Do I need new cables for HDMI 2.2?
For full HDMI 2.2 bandwidth, the Ultra96 HDMI Cable category is designed for the new specification. For HDMI 2.1 workflows up to 48Gbps, certified Ultra High Speed HDMI cables remain the relevant cable category. :contentReference[oaicite:7]{index=7}
Does TESmart offer HDMI KVM options for gaming desks?
Yes. TESmart offers HDMI KVM solutions for users who need to share displays, keyboard, mouse, audio, and USB peripherals across multiple computers or consoles. For current high-refresh HDMI 2.1 desks, check the TESmart HDMI KVM product line and match the model to your number of computers, number of monitors, and required display mode.
Conclusion
HDMI 2.2 is important because it pushes HDMI toward higher bandwidth, more demanding display formats, and better AV synchronization for complex systems. It is a future-facing standard that monitor, TV, GPU, cable, AV, and KVM ecosystems will continue to adopt.
But HDMI 2.1 is not obsolete. For most users building a desk today, the real problem is not whether HDMI 2.2 is stronger on paper. The real problem is how to switch a PS5, Xbox, gaming PC, MacBook, and work laptop across high-refresh displays and shared USB peripherals without daily cable changes.
If your setup is already built around HDMI 2.1 displays and devices, an HDMI 2.1 KVM is still the more realistic choice. It can address the desk you actually use now: display switching, EDID stability, keyboard and mouse control, USB peripheral sharing, audio routing, and multi-device workflow management.
