Every mainstream KVM switch treats a wireless keyboard the same way: it switches the USB receiver, not the Bluetooth pairing. That one detail is why the honest answer to a Bluetooth KVM search is a set of architectures rather than a list of radios. If you want the mechanics first, how a KVM switch works covers the video, USB and HID paths that every pick below relies on.
A Bluetooth keyboard belongs to the computer it was paired with. Switching an HDMI or USB-C KVM to the other machine does not move that pairing, and the manufacturers say so themselves: TESmart documents that its switches have no built-in Bluetooth, and AV Access gives the same answer for the iDock C20. Plug a 2.4GHz or Logi Bolt receiver into the switch instead and the picture changes completely, because the switch only ever sees a USB device.
So the eight picks below are grouped by what they actually do. Some use real Bluetooth HID, some replace the keyboard-and-mouse half of a KVM with multi-host peripherals, some carry a receiver between two hosts, and the rest are conventional KVMs that handle video and USB with no Bluetooth involved at all.

What Makes a Good Bluetooth KVM Solution?
The category only makes sense once you separate four decisions that a single "KVM" label hides: what switches the keyboard and mouse, what switches the video, what switches the USB peripherals, and what charges the laptops.
The Bluetooth question comes first. A Bluetooth radio built into a switch would have to emulate a Bluetooth HID device toward your keyboard and mouse, and the mainstream KVM vendors document that they do not do this. Their wireless support means receiver passthrough: the dongle plugs into the switch and is handed to whichever host is selected, exactly like a wired keyboard. That works with Logi Bolt, Logitech Unifying, 2.4GHz gaming receivers and any other USB dongle, and it fails completely for a mouse or keyboard paired directly to one machine's operating system.
Video is the second decision. A software or peripheral-only solution leaves the monitors physically attached to their computers, which removes EDID negotiation, hot-plug detection and DSC from the equation entirely. That is an advantage for anyone running 4K120 or higher, because no switch sits in the display path to renegotiate link training. A hardware KVM that does switch video has to cope with all of it, and the results differ sharply by model.
EDID emulation is not the same as EDID support. Emulation keeps the monitor logically present to the inactive computer, so windows, icon positions and resolutions survive a switch. "EDID support" on a spec sheet often means pass-through or HDCP re-keying only, and the inactive host still sees the display disconnect. For a Windows multi-monitor desk this is the difference between a clean switch and a desktop reshuffle every time.
macOS has its own constraint. Apple Silicon machines do not use DisplayPort MST to create two independent extended desktops. A dual-HDMI USB-C KVM dock that drives two independent screens on Windows will mirror them on a Mac, and no dock specification overrides the host GPU's display limit. If your second computer is a Mac, check that limit before the port count.
Managed laptops break the software options. Synergy and the enhanced Logitech features need installs and permissions. On a locked-down corporate machine, where software installation is blocked and Screen Recording or background permissions are controlled by IT, a physical USB switch and a shared receiver remain the only reliable path.
#1 across Basic/Pro: True Bluetooth HID, In Software
across is the closest thing to a literal Bluetooth KVM that currently exists, and it achieves it by inverting the topology. Instead of a switch containing a Bluetooth radio, the computer running the across Server advertises itself to the other machines as a Bluetooth keyboard and mouse. Those clients see a normal Bluetooth peripheral, pair with it, and the cursor and keystrokes cross over without any USB hardware in between.
Keyboard and mouse sharing is included in the Basic, T1, T2 and Pro editions. A single server can pair with up to six client devices, and the switching itself is configurable hotkeys plus software navigation between connected machines. Server support covers Windows 7/8.1/10/11, macOS 10.7 and newer, and both x86 and ARM Linux builds, with Android 6 and newer available as a client. The current production builds on the official download page are Windows 2.30b, macOS 2.30 and Linux 2.30a, all dated 2023, with the Android client at 2.30 from the same period.
Specs worth knowing before you commit:
- Genuine Bluetooth HID emulation, so no receiver changes hands and no USB switch is needed
- Up to six Bluetooth clients from one server, with hotkeys and software navigation between them
- Windows 7/8.1/10/11, macOS 10.7+, x86 and ARM Linux on the server side; Android 6+ as a client
- No video I/O, no EDID negotiation and no display rearrangement, because the monitors never move
- No hardware, no power supply and no cables
- Current production binaries date from March and June 2023
- One-time and subscription licensing options exist on the official store
Check across Bluetooth keyboard and mouse software on Amazon
Pros
- The only pick where Bluetooth itself is the transport
- Six clients from one server, which no multi-host peripheral matches
- No video path means no EDID, hot-plug or refresh-rate compromise
- Works across Windows, macOS, Linux and Android in one setup
Cons
- Does not switch a monitor, a dock, a webcam or storage
- Requires a software install on the server machine, which managed laptops often block
- 2023 build dates against a 2026 operating-system landscape
Verdict: across is the right answer when the question is genuinely about Bluetooth, and the wrong answer the moment you also want the monitor to follow.
Perfect for: developers and remote workers with two or three unlocked machines who only need one keyboard and mouse to reach all of them.
#2 Logitech Pebble 2 Combo: Bluetooth on a Budget
The Pebble 2 Combo replaces the keyboard-and-mouse half of a KVM rather than the switch itself. It bundles the Pebble Keys 2 K380s with the Pebble Mouse 2 M350s, launched on September 6, 2023, and the Tonal Graphite version carries part number 920-012061. Each device exposes three Easy-Switch channels, so a keyboard can be paired to three computers and moved between them with a button press.
The connection can be Bluetooth LE or the included Logi Bolt receiver, which matters more than it looks. Use Bluetooth and each device is bound to the host operating system, so it follows Easy-Switch and nothing else. Plug the Logi Bolt receiver into a USB switch instead and the pairing problem disappears, because the switch now carries an ordinary USB device. Logitech lists Windows, macOS, iPadOS and Android for Easy-Switch, and Logi Options+ is optional for basic switching.
What you get:
- Pebble Keys 2 K380s keyboard plus Pebble Mouse 2 M350s, part number 920-012061
- Three Easy-Switch channels per device
- Bluetooth LE, or the included Logi Bolt USB receiver
- Keyboard runs on 2×AAA, mouse on 1×AA, batteries included
- Windows, macOS, iPadOS and Android support
- No video, USB peripheral, Power Delivery or EDID switching
Check the Logitech Pebble 2 Combo on Amazon
Pros
- Two-device, three-host setup for the price of a pair of peripherals
- Bluetooth LE and a Logi Bolt receiver in the same box
- No software required for the basic channel switching
Cons
- Switches nothing except the keyboard and mouse
- Keyboard and mouse move on separate buttons unless a supported software layer synchronises them
- Three hosts is the ceiling
Verdict: Pebble 2 is the cheapest sensible start if your monitors already sit on their own inputs and you only need the peripherals to travel.
Perfect for: two-computer desks on a budget, where switching the monitor input by hand is acceptable.
#3 Logitech MX Keys S Combo: The Premium Peripheral Route
The MX Keys S Combo takes the same architecture upmarket: MX Keys S, MX Master 3S and the MX Palm Rest, sold as part number 920-011889 following its May 31, 2023 announcement and early-June availability. Each peripheral holds three connections over Bluetooth LE or Logi Bolt, and the Easy-Switch buttons work without any software at all.
The 2026 story is Enhanced Easy Switch, which aims to move several Logitech devices together rather than one at a time. The prerequisite is Logi Options+ running on the supported computers, and reported behaviour varies when part of the sequence is a mobile platform. This is the point where the product stops being a simple peripheral and starts behaving like a software-managed setup, with the same corporate-install problem that affects Synergy below. On a work laptop that forbids third-party software, users have reported falling back to switching keyboard and mouse separately, or parking a shared Logi Bolt receiver in a real USB switch.
What you get:
- MX Keys S keyboard, MX Master 3S mouse and MX Palm Rest, part number 920-011889
- Up to three connections per peripheral over Bluetooth LE or Logi Bolt
- Easy-Switch buttons for hardware-level channel changes
- Logi Options+ adds Flow, Smart Actions and 2026 Enhanced Easy Switch on supported combinations
- Rechargeable keyboard and mouse, with charging cables in the bundle
- No video, Power Delivery, USB hub or EDID functionality
Check the Logitech MX Keys S Combo on Amazon
Pros
- Genuine three-host Bluetooth switching without a switch
- Enhanced Easy Switch narrows the gap to one-button transitions
- Rechargeable, so no battery swaps
Cons
- Synchronised switching depends on Options+ being installed and running
- Locked-down work machines defeat the enhanced behaviour entirely
- Still switches nothing beyond the keyboard and mouse, as a two-computer KVM setup would
Verdict: MX Keys S Combo is the best peripheral-only answer for a mixed Windows and macOS desk, provided you control what gets installed on both machines.
Perfect for: freelancers and home-office users running a personal Mac and a personal PC, with no IT policy in the way.
#4 Plugable USB3-SWITCH2: Make a Receiver Follow the Switch
If you already own a Logitech receiver or a 2.4GHz gaming dongle, this is the cleanest way to move it between two computers. The USB3-SWITCH2 is a plain USB 3.0 switch at 5Gbps with two host-side USB-A connections and a single shared front USB-A port, and it has been in Plugable's catalogue since around 2014.
Nothing about it is Bluetooth, and that is exactly why it works. The switch sees a USB keyboard, mouse or receiver and hands it to whichever host is selected, with one physical button and an LED to show which side is live. There are no hotkeys and no drivers. The shared port supplies up to 5V/900mA, which is plenty for a dongle and not enough for a bus-powered drive. Video never enters the switch at all, so a 4K120 or high-refresh monitor keeps its direct connection, its VRR and its EDID untouched.
What you get:
- Two hosts, one shared front USB-A port
- USB 3.0 at 5Gbps, driverless
- Single physical button, LED host indicator, no hotkey switching
- Shared port supplies up to 5V/900mA (4.5W)
- Two 1m USB-A-to-B host cables included
- Not compatible with USB-C or Thunderbolt docks that depend on DP Alt Mode and Power Delivery
Check the Plugable USB3-SWITCH2 on Amazon
Pros
- Receiver-based wireless peripherals switch exactly like wired ones
- Zero interference with display bandwidth, EDID or VRR
- Driverless and inexpensive, with host cables in the box
Cons
- No video switching, so the monitor input is a second manual step
- No hotkeys, no Power Delivery, no laptop charging
- Treat any attached storage as a physical disconnect when you switch
Verdict: USB3-SWITCH2 is the safest pick for high-refresh setups, because it never touches the display path.
Perfect for: gamers and high-refresh users who want their 2.4GHz peripherals to follow the active computer and nothing else to change.
#5 UGREEN 25960: Budget Wired KVM, No Bluetooth
This is where the list returns to real switches, and the UGREEN 25960 is a compact example: one full-function USB-C source with DisplayPort Alt Mode, plus one HDMI computer with its own USB data connection, both driving a single HDMI monitor. It handles 3840×2160 at 60Hz, 2560×1440 at 120Hz and 1920×1080 at 240Hz, which covers a high-refresh 1440p panel as well as a 4K60 office screen.
Peripheral sharing runs at 5Gbps across three USB-A 3.0 ports and one USB-C data port. Switching is a chassis button or the included wired desktop controller, with no keyboard hotkeys and no app, and the unit is plug-and-play across Windows, macOS and Linux. Two limitations matter. There is no verified upstream laptop charging, because the USB-C power input feeds the switch itself and UGREEN explicitly notes the charger is not included. Persistent EDID emulation is also absent from the documented feature set, so the inactive computer will see the display disappear.
What you get:
- One USB-C DisplayPort Alt Mode host plus one HDMI host, one HDMI output
- 4K60, 1440p120 and 1080p240 support
- 5Gbps shared USB: three USB-A 3.0 ports and one USB-C data port
- Chassis button and wired desktop controller, no hotkeys
- No documented EDID emulation
- 1m HDMI cable, 1m full-feature USB-C cable, 1.5m USB-A-to-C cable and 1.5m desktop controller included
Check the UGREEN 25960 KVM Switch on Amazon
Pros
- One USB-C laptop and one HDMI desktop on a single screen
- No driver install on any of the three supported operating systems
- Wired controller keeps switching away from the keyboard
Cons
- No Bluetooth of any kind
- No laptop charging over the switch
- No documented EDID emulation, so windows can move after a switch
Verdict: UGREEN 25960 is the budget entry point for a single-screen desk, as long as you bring your own laptop charger.
Perfect for: one laptop plus one desktop on a 1440p or 4K monitor, where the laptop is already plugged into its own power supply.
#6 AV Access iDock C20: Two Laptops, Two Monitors, One Dock
The iDock C20 is the pick that most often gets mislabelled as a Bluetooth KVM, and the mislabelling is instructive. It is a dual-host dock with an integrated KVM, launched in early 2024, taking two USB-C laptops and driving two HDMI monitors, and it also carries Gigabit Ethernet, an SDXC reader, audio and a mixed USB 3.x and USB 2.0 hub downstream.
On the Bluetooth question the answer is direct: a keyboard or mouse paired to a laptop through Bluetooth stays with that laptop, while a wireless peripheral attached through its USB receiver is shared like any other device on the hub. On the display side, Windows hosts get dual 4K60 over MST, and the unit provides genuine EDID emulation that keeps monitor identity, resolution and window layout alive across a switch. Charging is 60W per laptop, delivered to both hosts rather than only the active one. The catch is macOS: Apple Silicon does not extend two independent desktops over this MST topology, so the two external screens mirror instead.
What you get:
- Two USB-C laptop hosts, dual HDMI outputs
- Dual 4K60 on Windows via MST, plus 2560×1440 at 144Hz and 1080p up to 240Hz
- Genuine EDID emulation to prevent desktop and window rearrangement
- 60W Power Delivery to each laptop, including the inactive host
- Gigabit Ethernet, SDXC reader, audio and 5Gbps USB data
- Chassis button and wired remote switching, no drivers required
- macOS: external displays mirror rather than extend independently
Check the AV Access iDock C20 on Amazon
Pros
- Two laptops fully docked from one chassis, charging included
- Real EDID emulation, which most KVMs in this price band do not offer
- Ethernet, card reader and audio without a second dock
Cons
- No Bluetooth; receiver-based wireless only
- Mirrored rather than extended displays on macOS
- Premium tier pricing for a two-host, two-screen setup
Verdict: iDock C20 is the strongest two-laptop desk here for Windows users, and the wrong buy for a Mac user expecting two extended screens. If that is your topology, the built-in KVM dock picks map the alternatives by operating system.
Perfect for: two Windows laptops sharing two monitors, Ethernet and peripherals, with both machines staying charged.
#7 Sabrent SB-TB4K: Thunderbolt 4 KVM for Certified Hosts
The SB-TB4K switches the Thunderbolt fabric rather than just the video and USB signals, which is a different class of device. Two Thunderbolt hosts share three downstream Thunderbolt 4 ports at 40Gbps plus four USB-A ports at 10Gbps, so NVMe enclosures and fast peripherals move between machines at full bandwidth instead of being throttled to 5Gbps.
Display support is host and topology dependent: up to 5K, 6K or 8K60 with DSC on a single output, 4K120 or 4K144 with DSC, or dual 4K60 where the host provides the necessary DisplayPort 1.4 topology. Power Delivery runs to 60W and only to the active host, which is the opposite of the iDock C20's behaviour and a common source of disappointment on a desk with two laptops. On EDID, the product materials describe support, but that should be read as pass-through rather than the persistent emulation described above. The included supply is 24V/5A, switching is a physical source button with no hotkeys, and Sabrent warns explicitly that the unit is intended for Thunderbolt-certified host systems only, with permanent damage possible on uncertified devices.
What you get:
- Two Thunderbolt 4 hosts, three downstream TB4 ports at 40Gbps, four USB-A at 10Gbps
- Single display up to 5K/6K/8K60 with DSC, or 4K120/144 with DSC
- Dual displays up to 4K60 on hosts with the right DP 1.4 topology
- Up to 60W Power Delivery to the active host only
- 24V/5A power supply and Thunderbolt cable included
- Physical source button only, no hotkey or software switching
- Thunderbolt-certified hosts required; uncertified devices risk permanent damage
Check the Sabrent SB-TB4K on Amazon
Pros
- Full 40Gbps Thunderbolt switching, not a 5Gbps USB hub
- Three downstream TB4 ports for high-speed storage and docks
- No Bluetooth pretence at all, and the documentation says so
Cons
- Only the active host charges through the KVM
- Certification requirement rules out adapted or uncertified chains
- Physical button switching with no hotkeys
Verdict: SB-TB4K is the right tool for a Thunderbolt workstation sharing fast peripherals, and a risky one to combine with anything uncertified. For host limits at these resolutions, see the Thunderbolt 4 dock breakdown.
Perfect for: two certified Thunderbolt laptops or desktops sharing NVMe storage and 4K monitors.
#8 Synergy 3 Plus: Network Software KVM
Synergy moves the keyboard and mouse over the local network rather than over Bluetooth or USB, and the stable build is version 3.6.3, released June 12, 2026. The Plus tier controls up to five computers, with cursor crossing between screens and configurable hotkeys, and Plus adds keystroke forwarding plus TLS and SSL encryption on the wire.
The architecture assumes every computer keeps its own display, because Synergy does not share video at all. That removes EDID, MST and refresh-rate questions from your setup entirely, and it also removes the need for any hardware between the machines. The requirements are a working LAN or Wi-Fi path with no internet connection needed, software installed on every participating computer, and an operating system from the supported list of Windows, macOS, Linux and Raspberry Pi OS. The licensing distinction matters in a work context: the inexpensive personal edition is designated for individual personal use, while managed or company-owned devices fall under business licensing.
What you get:
- Up to five computers on one keyboard and mouse, Plus tier
- Cursor crossing and configurable keyboard shortcuts between machines
- Keystroke forwarding and TLS/SSL encryption in Plus
- LAN, Wi-Fi or Ethernet transport; no internet connection required
- Windows, macOS, Linux and Raspberry Pi OS support
- No video, USB, Power Delivery or EDID switching; each computer needs its own screen
- Personal licence intended for individual use, business licence for managed devices
Check Synergy 3 keyboard and mouse sharing on Amazon
Pros
- Five computers from one keyboard and mouse, more than any hardware pick
- No display path involvement, so no EDID or refresh compromise
- Works across mixed operating systems on the same desk
Cons
- Requires an install on every machine, which corporate policy often blocks
- VPN, firewall and network segmentation can break the connection
- No video sharing, so every computer needs its own monitor
Verdict: Synergy 3 Plus is the most flexible software answer for machines you control, and the least dependable one for a corporate laptop you do not.
Perfect for: developers with a mixed Linux, macOS and Windows lab, each already on its own display.

Which Solution Should You Buy?
Two personal computers, no IT restrictions. Start with across if the keyboard and mouse are the only things that need to move, because it is the sole pick using real Bluetooth HID. If you would rather not install software on every machine, the MX Keys S Combo does the same job through the peripherals themselves.
A work laptop you do not control. Software is off the table. A Plugable USB3-SWITCH2 with a shared Logi Bolt receiver is the reliable answer, and a Logitech Pebble 2 Combo gives you the peripherals to put on it.
High-refresh or 4K120 displays. Keep the monitors wired straight to the computers and switch only the peripherals. Any USB switch here costs you nothing in display bandwidth, whereas a video KVM inserts another link-training and EDID boundary.
Two Windows laptops and two monitors. The AV Access iDock C20 covers displays, Ethernet, card reader and charging in one chassis, and its EDID emulation keeps window layouts intact.
A Mac in the mix. Do not buy a dual-output MST dock expecting two extended desktops. macOS mirrors on that topology, so either accept mirrored screens, use a single external display, or plan around the host's native display limit.
A Thunderbolt workstation with fast storage. The Sabrent SB-TB4K is the only pick that switches the Thunderbolt fabric itself, provided both hosts are certified.
Conclusion
There is no mainstream hardware switch with a Bluetooth radio that pairs directly with your keyboard and mouse, and every search result that suggests otherwise is blending three different things: genuine Bluetooth HID, USB receiver passthrough, and plain wired switching. Once you separate them, the buying decision becomes simple. If Bluetooth itself is the requirement, across is the only genuine answer. If the peripherals simply need to travel between machines, a multi-host Logitech setup or a shared receiver on a USB switch is cheaper, faster and more predictable.
For anything involving video, the deciding factors are EDID behaviour and operating-system display limits, not wireless technology. The iDock C20's emulation and the SB-TB4K's full Thunderbolt switching solve different halves of that problem, and neither has anything to do with Bluetooth.
