The Ouluoa wins for laptop-plus-desktop desks. - Author: Samuel Harris - Tags: Computers & Networking, Computer Accessories, Home Office The best compact dual monitor KVM switch for most desks is the Ouluoa USB C KVM Switch, because it swallows a laptop and a desktop into one 5.24-inch shell, pushes 4K@60Hz across two HDMI screens, and pipes 100W back into the laptop through the same cable. If both of your machines are tower PCs with HDMI outputs, the JCYMELE 4K@144Hz KVM Switch is the more sensible entry point, with a two-year stated warranty and a body that fits in the same palm.

[The verdict](#the-verdict) 15. [FAQ](#faq) ## How I narrowed a crowded shelf to seven Most compact dual monitor KVM switch guides compare resolution numbers. That is not what decides it. The port set does. A switch that lists 8K@60Hz is useless if your GPU outputs USB-C and the box only takes DisplayPort in. So I started with what goes into the back, not what comes out the front. Three reasons picks were cut from the shortlist: 1. **Single-monitor units disguised as dual.** A "2 computers 1 monitor" KVM is not a dual monitor switch, no matter how the marketing reads. Only one made the cut here, and it earned a specific role. 2. **Bulky rack-style bodies.** A compact dual monitor KVM switch should tuck behind a monitor stand. Anything longer than about six inches on its widest side was dropped. 3. **No published USB hub.** If the switch cannot share a mouse, keyboard and one flash drive between machines, it is a video switch, not a KVM. What survived: five HDMI switches, one DisplayPort switch, one USB-C dock-style unit. Every one carries a USB 3.0 hub, an external 12V power adapter, and a desktop or wired remote controller so you are not reaching behind the case to toggle inputs. The seven cover three price positions and three port families, which is the point: this is a category where the right pick is the one that matches your cables, not the one with the biggest number on the spec sheet. ## Best compact dual monitor KVM switch at a glance | Pick | Video ports | Max resolution | Price | | --------------------------------------------------------------------------------------------------------- | --------------------- | ----------------------- | ------------------------------------------------------------------ | | **Best overall**[Ouluoa USB C KVM Switch](https://www.amazon.com/dp/B0H9RGBN5K?tag=a9droid-20) | 2 HDMI out, USB-C in | 4K@60Hz claim | [Check Price](https://www.amazon.com/dp/B0H9RGBN5K?tag=a9droid-20) | | **Best for beginners**[JCYMELE 4K@144Hz KVM Switch](https://www.amazon.com/dp/B0GZT37QR3?tag=a9droid-20) | 2 DisplayPort | 4K@144Hz, 8K@60Hz claim | [Check Price](https://www.amazon.com/dp/B0GZT37QR3?tag=a9droid-20) | | **Best for heavy use**[CMSTEDCD 8K HDMI KVM Switch](https://www.amazon.com/dp/B0H31Z26CW?tag=a9droid-20) | 2 HDMI | 8K@60Hz, 4K@120Hz claim | [Check Price](https://www.amazon.com/dp/B0H31Z26CW?tag=a9droid-20) | | **Best budget pick**[Hearvo USB 3.0 HDMI KVM Switch](https://www.amazon.com/dp/B0D5D4FK1H?tag=a9droid-20) | 2 HDMI, 1 monitor out | 4K@60Hz claim | [Check Price](https://www.amazon.com/dp/B0D5D4FK1H?tag=a9droid-20) | | **Best for families**[UGREEN HDMI KVM Switch AK500](https://www.amazon.com/dp/B0DXF66SWR?tag=a9droid-20) | 2 HDMI | 4K@60Hz claim | [Check Price](https://www.amazon.com/dp/B0DXF66SWR?tag=a9droid-20) | | **Most versatile**[TIGKTING HDMI KVM Switch](https://www.amazon.com/dp/B0H2YPSL9R?tag=a9droid-20) | 2 HDMI | 4K@60Hz claim | [Check Price](https://www.amazon.com/dp/B0H2YPSL9R?tag=a9droid-20) | | **Best upgrade**[UGREEN 8K DisplayPort KVM Switch](https://www.amazon.com/dp/B0DXF5Z23S?tag=a9droid-20) | 2 DisplayPort | 8K@60Hz claim | [Check Price](https://www.amazon.com/dp/B0DXF5Z23S?tag=a9droid-20) | ## What actually decides a dual monitor KVM switch? Ignore the headline resolution for a moment. The real deciding criterion is how many of your existing cables plug straight in with no adapter. A 4K@144Hz DisplayPort switch is the wrong choice if your work laptop only offers HDMI and USB-C, because you will need two active converters and the switch will fight the EDID handshake every time you toggle inputs. Ask three questions before you compare specifications: - What signal does each machine actually output? HDMI, DisplayPort, or USB-C alt-mode? - Do both machines output the same signal, or do you need a switch that mixes inputs? - Does the laptop need to charge from the switch, or does it stay plugged into its own brick? Only the Ouluoa in this set handles the mixed case where one input is USB-C and video comes out two HDMI ports, and only the Ouluoa publishes 100W PD passthrough. Every other pick here assumes both computers hand over the same kind of video plug. ## 1\. Ouluoa USB C KVM Switch — Best overall **A KVM and a laptop dock in the same 1.3-inch tall case, and the only pick here that charges the laptop while it switches.** [![Ouluoa compact USB-C KVM switch showing HDMI outputs and USB-C input — proves the mixed-signal design a laptop-plus-desktop desk needs](https://m.media-amazon.com/images/I/41drGnu9aGL._SL500_.jpg)](https://www.amazon.com/dp/B0H9RGBN5K?tag=a9droid-20) **Best for:** a laptop-plus-desktop desk that needs 100W charging in one cable **Skip it if:** both machines are towers with HDMI outputs Ouluoa takes the mixed-signal problem that trips up every other compact dual monitor KVM switch and solves it in a body 1.3 x 5.24 x 2.52 in. The laptop feeds in over USB-C, the desktop feeds in over its own connection, and both drive two HDMI monitors. Ouluoa says the video path is rated at 4K@60Hz with 1080p and 720p backward compatibility, and that the built-in 80W PD charging port keeps the laptop topped up through the same cable that carries video and USB. The listing also claims 100W PD elsewhere in the copy, so treat the exact wattage as "high enough to run most work laptops" and confirm against your own machine. Three USB 3.0 ports and a USB-C port sit on the hub, rated at 5Gbps by the manufacturer, so wireless dongles, a printer and a portable drive can all live on the switch and follow whichever machine has focus. An external 12V adapter powers the whole thing, which matters for spinning-disk drives that would starve on bus power. The trade-off is real: this is the most expensive pick here, and Ouluoa is the smallest brand in the set with the thinnest published specification list, no stated warranty and only one seller listing it. **Pros:** - Only pick that mixes USB-C laptop input with HDMI dual output - Manufacturer claim of 80W PD charging over the USB-C link - Three USB 3.0 ports and one USB-C for peripherals - Smallest footprint in the set at 5.24 in wide - External 12V adapter avoids bus-power drop-outs **Cons:** - Most expensive pick here for the least-documented brand - No stated warranty in the listing - 4K@60Hz is a claim, not a rated figure - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0H9RGBN5K?tag=a9droid-20) ## 2\. JCYMELE 4K@144Hz KVM Switch — Best for beginners **A DisplayPort switch with a two-year warranty and a genuinely plug-and-play switching flow.** [![JCYMELE DisplayPort KVM switch in deep blue with desktop controller cable — proves the button-plus-remote workflow a first-time buyer wants](https://m.media-amazon.com/images/I/41NkjvqiAPL._SL500_.jpg)](https://www.amazon.com/dp/B0GZT37QR3?tag=a9droid-20) **Best for:** a first KVM buyer with two DisplayPort PCs **Skip it if:** your GPUs only carry HDMI JCYMELE is the compact dual monitor KVM switch to buy if you have never owned one before and both your machines carry DisplayPort out. The body measures 5.91 x 2.68 x 1.5 in, so it slots behind a monitor arm without notice, and JCYMELE publishes a two-year warranty on the listing, which is uncommon in this price position and one of only two warranties published across the seven picks. The manufacturer says the video path handles 4K@144Hz and 8K@60Hz, with backward compatibility down to 1080p. Two switching methods are documented: a Select button on the case and a wired desktop controller for the keyboard tray. Four USB 3.0 ports let you share a keyboard, a mouse, and two more devices between the two computers, and JCYMELE claims 5Gbps on the hub. A 12V DC adapter powers the switch externally, which the listing calls out as the reason USB devices stay stable when a high-draw drive plugs in. The trade-off against the CMSTEDCD is straightforward: JCYMELE is DisplayPort, CMSTEDCD is HDMI, and the price rank sits below the CMSTEDCD in this set for a broadly similar spec sheet. **Pros:** - Two-year stated warranty - DisplayPort supports 4K@144Hz claim and 8K@60Hz claim - Compact 5.91 in body - Four USB 3.0 ports with desktop controller - External 12V adapter for stable peripheral power **Cons:** - DisplayPort-only inputs, no HDMI fallback - Refresh rate figures are manufacturer claims - No USB-C input for a laptop - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0GZT37QR3?tag=a9droid-20) ## 3\. CMSTEDCD 8K HDMI KVM Switch — Best for heavy use **HDMI 8K@60Hz claim in a 5.91-inch body, aimed at gaming and colour work.** [![CMSTEDCD 8K HDMI KVM switch with four USB 3.0 ports on the front face — proves the peripheral density gamers and editors need](https://m.media-amazon.com/images/I/41y+BYs50pL._SL500_.jpg)](https://www.amazon.com/dp/B0H31Z26CW?tag=a9droid-20) **Best for:** gamers pushing 4K@120Hz or 8K@60Hz on HDMI **Skip it if:** your monitors top out at 1080p CMSTEDCD is the compact dual monitor KVM switch for the person whose bottleneck is bandwidth. The manufacturer claim is 8K@60Hz and 4K@120Hz over HDMI, with backward compatibility to 4K@60Hz and 1080p, and it sits in the mid tier of this set on price. Dimensions of 1.42 x 5.91 x 2.56 in match the JCYMELE almost exactly, which is not a coincidence: both use a similar chassis with different port stacks. The USB side gets a 4-port USB 3.0 hub at 5Gbps by the manufacturer's claim, backward compatible with USB 2.0 devices. Two switching methods are supported: panel buttons and an included wired remote. The listing calls out the 12V adapter with a specific warning that PC USB ports cannot power high-draw devices like external hard drives through a bus-powered switch, so this is one to keep plugged into its own brick. The trade-off is the missing warranty line: CMSTEDCD does not publish one, where JCYMELE and TIGKTING both do. Buy this pick for the refresh rate, not the peace of mind. **Pros:** - Manufacturer claim of 8K@60Hz and 4K@120Hz over HDMI - Four USB 3.0 ports rated at 5Gbps - Panel-button and wired-remote switching - External 12V adapter handles high-draw peripherals - Mid-range price position for the highest published HDMI ceiling here **Cons:** - No published warranty - Refresh rate figures are manufacturer claims - HDMI-only inputs - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0H31Z26CW?tag=a9droid-20) ## 4\. Hearvo USB 3.0 HDMI KVM Switch — Best budget pick **A cheapest-of-set HDMI switch that shares a single monitor between two PCs. Read that sentence twice.** [![Hearvo compact HDMI KVM switch in black with three USB-A and one USB-C port — proves the port mix a single-monitor desk actually uses](https://m.media-amazon.com/images/I/41ll9M3dnWL._SL500_.jpg)](https://www.amazon.com/dp/B0D5D4FK1H?tag=a9droid-20) **Best for:** two PCs sharing a single monitor at 4K@60Hz **Skip it if:** you actually need two screens Hearvo is the cheapest of the seven, and it is included here on purpose to flag a mistake buyers make. The listing supports two computers and one monitor, not two monitors, despite living on the shelf next to true dual-monitor switches at similar sizes. If your desk has one big screen and two towers under it, this is the right switch and probably the right price. If your desk has two screens, keep scrolling. Where it does fit, it fits well. The body is 0.8 x 5 x 2.4 in, which is the flattest and shortest chassis in the group. Four USB 3.0 ports split as three USB-A and one USB-C, so a modern keyboard, a mouse dongle, a webcam and a phone dock can all live on the switch. Hearvo says the video path is 4K@60Hz with HDCP 2.2, and it calls out Adaptive EDID as the mechanism that keeps the display awake across a signal swap. Two switching methods, the on-case button and a wired remote, are documented. The trade-off is written on the tin: one monitor, not two. **Pros:** - Cheapest of the seven - Flattest and shortest body at 0.8 in tall - Three USB-A plus one USB-C port - Adaptive EDID claim for stable handoff - HDCP 2.2 claim for protected content **Cons:** - Single monitor only, not a true dual monitor KVM - No published warranty - HDMI-only inputs - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0D5D4FK1H?tag=a9droid-20) ## 5\. UGREEN HDMI KVM Switch AK500 — Best for families **A well-documented HDMI switch from the largest brand here, sold by more than one seller.** [![UGREEN AK500 HDMI KVM switch with front-panel button and desktop controller port — proves the shared-desk workflow multiple users can learn quickly](https://m.media-amazon.com/images/I/41ZrB2w7oOL._SL500_.jpg)](https://www.amazon.com/dp/B0DXF66SWR?tag=a9droid-20) **Best for:** a shared home desk with two HDMI PCs and mixed operating systems **Skip it if:** you want the fastest published refresh rate here The UGREEN AK500 is the compact dual monitor KVM switch you buy when more than one person is going to use the desk. UGREEN publishes broad OS support, calling out Windows, macOS and Linux compatibility on the listing, and this is one of two picks in the set with more than one seller stocking it, which is a small signal that the supply chain behind it is not a single import lot. The video ceiling is a 4K@60Hz manufacturer claim over HDMI, with HDMI 2.0 and HDCP 2.2 support in the listing text. The USB hub carries four ports split as three USB-A and one USB-C, matching the layout on the DisplayPort UGREEN below. Switching is by panel button or the desktop controller in the box, and the dimensions of 1.18 x 6.18 x 2.83 in put it near the widest end of the shortlist, though still comfortably behind a 27-inch monitor. The trade-off against the CMSTEDCD is refresh rate. UGREEN tops out at a 4K@60Hz claim on this HDMI model, where CMSTEDCD's HDMI switch claims 4K@120Hz. Families rarely need the extra headroom, so the OS compatibility copy earns its place. **Pros:** - OS support claim covers Windows, macOS and Linux - Two sellers list it, unlike most of the set - Four USB 3.0 ports including one USB-C - Panel-button and desktop-controller switching - Established brand with a longer public catalogue **Cons:** - 4K@60Hz ceiling trails the CMSTEDCD's HDMI claim - Premium price for the AK500's spec sheet - Refresh rate figure is a manufacturer claim - No published warranty on the listing [Check Price on Amazon](https://www.amazon.com/dp/B0DXF66SWR?tag=a9droid-20) ## 6\. TIGKTING HDMI KVM Switch — Most versatile **Extended mode, duplicate mode and a two-year warranty in an entry-tier body.** [![TIGKTING dual-screen HDMI KVM switch with USB 3.0 hub — proves the mode-flexible layout freelancers and hybrid workers reach for](https://m.media-amazon.com/images/I/51uqBDyacxL._SL500_.jpg)](https://www.amazon.com/dp/B0H2YPSL9R?tag=a9droid-20) **Best for:** someone who wants extended and duplicate modes without paying premium **Skip it if:** you need DisplayPort or USB-C inputs TIGKTING sits in the entry price position but publishes the same warranty length as the JCYMELE: two years. Dimensions of 1.42 x 5.91 x 2.56 in match the JCYMELE and the CMSTEDCD exactly, and the deep blue chassis suggests a shared OEM base. What differentiates it inside this set is the documentation of two display modes: extended, so each of your two monitors shows a different desktop, and duplicate, so both mirror. Not every HDMI switch here spells that out on the listing, and it matters if you present from one machine to a projector while running your own workspace on the other. The USB side is four USB 3.0 ports working simultaneously, which the manufacturer calls out as a way to skip a separate hub. Switching is a physical button on the case or the desktop controller. TIGKTING claims 4K@60Hz over HDMI with backward compatibility to 1440p@60Hz and 1080p@60Hz. The trade-off against the UGREEN AK500 is brand depth: UGREEN has a larger public catalogue and more sellers, while TIGKTING offers the warranty and a lower price position. For most workspaces, the warranty wins. **Pros:** - Two-year stated warranty - Extended and duplicate modes documented on the listing - Entry-tier price position - Four USB 3.0 ports working simultaneously - Physical button and desktop controller switching **Cons:** - 4K@60Hz claim is behind the CMSTEDCD's HDMI ceiling - HDMI-only inputs - Refresh rate figure is a manufacturer claim - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0H2YPSL9R?tag=a9droid-20) ## 7\. UGREEN 8K DisplayPort KVM Switch — Best upgrade **A DisplayPort 1.4 switch aimed at 8K workflows and high-refresh gaming.** [![UGREEN DisplayPort 8K KVM switch in an aluminium shell — proves the build a high-refresh workflow expects](https://m.media-amazon.com/images/I/41jfRwJIO6L._SL500_.jpg)](https://www.amazon.com/dp/B0DXF5Z23S?tag=a9droid-20) **Best for:** high-refresh gaming and 8K workflows on DisplayPort **Skip it if:** your rigs only output HDMI or USB-C The UGREEN 55851 is the ceiling of this set. UGREEN says the video path handles 8K@60Hz on DisplayPort 1.4, with backward compatibility down through 8K@30Hz, 4K@240Hz, 4K@144Hz, 4K@120Hz and 4K@60Hz. That is a broader ladder of supported refresh rates than any other pick documents, and it is the reason to buy this switch instead of the JCYMELE if you have monitors that actually accept those rates. Weight is a published 1.76 lb in an aluminium chassis, which is heavier than the plastic bodies in this set and part of what the extra spend buys. Three sellers list it, which is the highest offer count of the seven and the strongest supply signal in the group. The USB hub matches the AK500: four USB 3.0 ports split as three USB-A and one USB-C. OS support is called out for Windows, macOS and Linux, and switching is button or desktop controller. The trade-off is straightforward: no HDMI, no USB-C video input, and the second-highest price position in the set. It is the right compact dual monitor KVM switch for one specific rig, not for a household. **Pros:** - Manufacturer claim of 8K@60Hz on DisplayPort 1.4 - Backward compatibility ladder down to 4K@60Hz documented - Aluminium chassis at a published 1.76 lb - Three sellers list it - OS support claim covers Windows, macOS and Linux **Cons:** - No HDMI or USB-C video input - Second-highest price position here - Refresh rate figures are manufacturer claims - No published warranty on the listing [Check Price on Amazon](https://www.amazon.com/dp/B0DXF5Z23S?tag=a9droid-20) ## HDMI, DisplayPort or USB-C: which port set fits your desk? The port on the back of your GPU decides the switch. Force it and you pay twice: once for the KVM, once for the active adapters that make the KVM work. - **HDMI on both machines.** Six of the seven picks fit. CMSTEDCD gives the highest HDMI refresh claim in the set. UGREEN AK500 gives the deepest brand catalogue. TIGKTING gives a warranty at entry price. Hearvo gives the cheapest single-monitor build. - **DisplayPort on both machines.** Two picks fit. JCYMELE is the entry point. UGREEN 55851 is the upgrade for anyone chasing high-refresh 4K or genuine 8K claims. - **USB-C laptop plus HDMI desktop.** Only the Ouluoa handles this without adapters, and only the Ouluoa charges the laptop while it switches. - **Mixed HDMI and DisplayPort machines.** None of the seven mix these two directly. Buy the switch that matches the machine you use more, and add an adapter to the other. The reason this ordering matters: EDID handshakes fail more often across active adapters than across native cables, and a KVM that keeps losing your monitor is worse than no KVM at all. ## How small is small enough for a two-monitor desk? Compact is a soft word, so here is the hard version. The seven picks span two clear sizes. The **flat category** contains the Hearvo at 0.8 x 5 x 2.4 in and the Ouluoa at 1.3 x 5.24 x 2.52 in. Both slide under a monitor stand, both hide behind a laptop lid on a shared desk, and neither adds visible cable bulk to a clean setup. The **mid category** contains four picks with near-identical footprints. JCYMELE at 5.91 x 2.68 x 1.5 in, CMSTEDCD and TIGKTING at 1.42 x 5.91 x 2.56 in, and the two UGREEN units at 1.18 x 6.18 x 2.83 in. All four sit behind a 24- to 27-inch monitor and disappear from view. The UGREEN chassis is the widest at 6.18 in, and the tallest at 2.83 in, which matters only if you cable-tie it to a thin monitor arm. None of the seven is a rack-mount unit, and none has fan noise documented on the listing. If the KVM is going on the desk in front of you, pick the flat category. If it lives behind the monitor, size matters less than port layout. ## What the listings do not tell you Three details never appear in a compact dual monitor KVM switch listing, and all three affect the buying decision more than headline resolution. 1. **Which USB ports on the hub are wired to which computer.** Most of these switches route all four USB ports to whichever machine has focus, so a webcam plugged into the switch follows the active PC. Confirm from your seller if you need one port pinned to one machine. 2. **How the switch handles a monitor waking from sleep.** Adaptive EDID is a claim on the Hearvo listing and implied on others. In practice, cheaper switches sometimes lose one of the two displays on a cold boot until you cycle the input. External 12V power, which every pick here has, reduces the frequency, but does not eliminate it. 3. **What "USB-C" means in the port label.** On the Ouluoa it means video-in from a laptop with 100W PD passthrough claim. On the JCYMELE, CMSTEDCD, TIGKTING, Hearvo, UGREEN AK500 and UGREEN 55851 it means a USB-C data port on the hub, not a video path. Read the port list twice. None of these is a reason to avoid a compact dual monitor KVM switch. All three are reasons to check the exact listing before you buy, because the specifications page and the reality of a signal chain are two different documents. ## The verdict The Ouluoa USB C KVM Switch is the best compact dual monitor KVM switch for the most common modern desk: one laptop, one desktop, two HDMI monitors, and a demand that the laptop charge from the same cable it uses to switch. Nothing else in the set does that job. It is the most expensive pick here, and the brand is the smallest, but the port layout is unique and the manufacturer claim of 4K@60Hz across two HDMI outputs is enough for almost any office monitor sold today. Two conditions flip the pick. First, if both of your machines are towers with HDMI outputs and you want a stated warranty, the TIGKTING HDMI KVM Switch is the better buy: two years of published cover, extended and duplicate modes documented, and an entry-tier price position. Second, if both machines carry DisplayPort and you push 4K@120Hz or higher on your monitors, the UGREEN 8K DisplayPort KVM Switch is the correct upgrade, with a published backward compatibility ladder no other pick matches and the highest offer count in the set. The CMSTEDCD wins the same job on HDMI. Everything else in the shortlist earns its place for a specific desk, not for every desk. ## FAQ ### What does a compact dual monitor KVM switch actually do? A compact dual monitor KVM switch lets one keyboard, one mouse and a small stack of USB devices control two computers running side by side on two shared monitors. You press a button or tap a desktop remote, and the video, keyboard and mouse jump to the other machine while your peripherals stay put. The compact part matters because the box sits on a desk, not in a rack. ### Is a compact dual monitor KVM switch worth it over software like Synergy? A compact dual monitor KVM switch is worth it when you need the second machine's video on your own monitors, not just its mouse cursor. Software like Synergy shares input between two computers that each already have their own displays. A hardware KVM shares the displays too, plus USB drives, webcams and printers, and it works before either operating system finishes booting. ### Will 4K@144Hz or 8K@60Hz on these listings actually reach my monitor? Refresh rate claims like 4K@144Hz on the JCYMELE and 8K@60Hz on the UGREEN 55851 assume the whole cable chain supports the bandwidth: certified DisplayPort 1.4 cables, a GPU output rated for the mode, and a monitor input rated to receive it. If any link in that chain is older or unrated, the switch will negotiate down to whichever mode all three components agree on. ### CMSTEDCD versus UGREEN AK500 for a family HDMI desk? CMSTEDCD versus UGREEN AK500 comes down to refresh headroom against brand depth. CMSTEDCD publishes an 8K@60Hz and 4K@120Hz HDMI claim, sits mid-tier on price, and has one seller. UGREEN AK500 publishes a 4K@60Hz HDMI claim, sits premium on price, has two sellers and a longer public catalogue. Families rarely need above 4K@60Hz, so AK500 usually wins the shared-desk brief. ### What is the biggest mistake people make buying a compact dual monitor KVM switch? The biggest mistake people make is buying a switch by resolution number instead of by port match. An 8K@60Hz DisplayPort switch is useless on a desk with two HDMI PCs, and a 4K HDMI switch is useless on a laptop that only outputs USB-C. Check the port on the back of each machine first, then filter the shortlist by which switches accept that port natively. Two monitors, two computers, one keyboard, one desk that finally makes sense. Start by looking at the back of the machine you use most, and match the switch to the cable that is already there.
