Best KVM Switches for Two Computers in 2026

The UGREEN HDMI KVM Switch for 2 monitors and 2 computers is the KVM to buy for most desks: at $64.99 it shares two 4K 60Hz monitors and four USB 3.0 ports between two machines, and it ships with every cable. If your monitor runs above 60Hz at 4K or you game on a high-refresh 1440p panel, get the Cable Matters DisplayPort 1.4 KVM instead.

• Best overall: UGREEN HDMI KVM Switch 2 Monitors 2 Computers: two 4K 60Hz screens, four USB 3.0 ports and four HDMI cables in the box for $64.99.
• Best for high-refresh gaming monitors: Cable Matters USB 3.0 KVM Switch, DisplayPort 1.4: listed for 4K at 240Hz and 8K at 60Hz, with an RF remote, at $95.99.
• Best for multi-monitor work that switches all day: TESmart HDMI KVM Switch 2 Monitors 2 Computers: EDID emulators keep your window layout put when you flip machines, at $199.99.

Prices as of October 16, 2026.

At $64.99, the dual-monitor UGREEN is priced low enough that a one-screen switch rarely makes sense. Two familiar names are missing: the single-monitor UGREEN and the Cable Matters HDMI switch with the RF remote, because neither had a buyable Amazon offer today.

Quick comparison

UGREEN HDMI KVM Switch 2 Monitors 2 Computers: the one to buy

Here's the odd thing about this category. A dual-monitor switch with every cable in the box is $64.99, and at that price there's very little reason to buy a one-screen KVM unless you are certain you'll never add a second display.

The box is the other argument. Four HDMI cables, two USB cables, a power brick and the little desktop controller. A dual-monitor KVM needs six cables before it does anything, and switches that ship bare leave you buying four HDMI 2.0 cables on top.

Per UGREEN's spec sheet, the four USB 3.0 ports (three USB-A, one USB-C) run at 5Gbps, so a shared portable SSD actually moves at SSD speeds. Supported modes include 4K 60Hz, 1440p at 120Hz and 1080p at 240Hz.

Two limits, both from the listing and retailer spec sheets. First, there's no hotkey switching, only the button and the controller. Second, both monitors always show the same computer. You can't put PC1 on the left screen and PC2 on the right.

Skip it if you run a tightly arranged multi-monitor layout and switch machines ten times a day. Without advertised EDID emulation, the machine you leave can think its monitors were unplugged, and Windows tends to pile your windows onto one screen when you come back. That's the TESmart's job.

Cable Matters DisplayPort 1.4 KVM: for high-refresh monitors

Every HDMI KVM on this page tops out at 4K 60Hz. That's fine for an office monitor and a waste on a $500 high-refresh gaming panel. This Cable Matters switch is the cheapest way around it on Amazon today: $95.99 for a DisplayPort 1.4 KVM that Cable Matters lists for 4K at 240Hz (with DSC), 1440p at 244Hz and 8K at 60Hz.

FreeSync and G-SYNC pass through, per the listing. That matters more than it sounds. Plenty of cheap DP switches pass the picture and quietly break variable refresh.

The RF remote is the nice extra. It's radio, not infrared, so it works when the switch is tucked behind a monitor arm. Cable Matters' HDMI version of this switch had the same remote, and it was the main reason people bought it. That one isn't buyable on Amazon today, which is why this DP model replaced it here.

Honestly, the real gate is your hardware. Both computers need DisplayPort out. Most desktop graphics cards have three DP ports, so a gaming PC is easy. A work laptop usually means a USB-C to DisplayPort cable, and only if its USB-C port supports DisplayPort Alt Mode.

Skip it if you have two monitors to share. It's a one-screen switch, and stacking two of them for two monitors gets messy fast.

TESmart Dual Monitor HDMI KVM: for heavy multi-monitor work

Most people should not pay $199.99 for a KVM. This one earns it for a specific person: somebody running two monitors with apps pinned to exact positions, flipping between a work laptop and a home PC all day.

The reason is EDID emulation, which TESmart lists right in the product title. EDID is the handshake where a monitor tells a computer what it is. Without emulation, switching away looks like an unplug to the computer you left, so it rearranges your desktop. With it, both machines think their monitors never left. That's the whole product, really.

TESmart also lists two display modes: both screens follow one computer, or each computer keeps one monitor. The second mode is handy if you want a work machine on one screen and a personal one on the other while sharing a single keyboard. UGREEN's switch can't do that.

The tradeoff is USB 2.0 on the shared ports, 480Mbps. Keyboards, mice, webcams and printers don't care. A shared external SSD crawls. If you move files between machines a lot, the UGREEN's USB 3.0 ports are the better fit.

Skip it if you switch once or twice a day. The window shuffle is a minor annoyance at that rate, and the UGREEN does everything else for $135 less.

The one people see first, and why it's not here

The single-monitor UGREEN USB 3.0 HDMI KVM is the one most people find first. It's still a good little switch, but it isn't available to buy on Amazon today. Given the dual UGREEN sells for $64.99, I wouldn't chase the single-screen one even when it comes back: a second video output is worth having, and most desks grow a second monitor eventually.

How to choose a KVM switch

Count monitors before anything else

One monitor shared between two computers is the simple case, and any switch here handles it. Two monitors is where most buying mistakes happen: people buy a one-screen switch and plug the second monitor straight into one PC, then switch the second screen by hand from the monitor's menu forever. If both screens should follow you, buy a dual-monitor KVM from day one. At $64.99 for the UGREEN, there's not much savings in going single.

Match the port to your monitor's refresh rate

HDMI 2.0 KVMs carry 4K at 60Hz. For an office monitor, that's the full spec. For a 4K 144Hz or 240Hz gaming monitor, it throws away most of what you paid for. The rule:

• 4K 60Hz or 1440p at 120Hz or less: an HDMI KVM is fine.
• 4K above 60Hz, or 1440p at 165Hz and up: get DisplayPort 1.4 with DSC, like the Cable Matters.

Decide whether EDID emulation is worth $135

If you only use one monitor, EDID matters a lot less. With two or more screens and frequent switching, it's the difference between a desk that works and one that rearranges itself. Most budget KVMs don't advertise it. The TESmart does, in writing, and that's the one feature you're paying extra for.

USB 3.0 vs USB 2.0 ports

USB 2.0 (480Mbps) is plenty for keyboards, mice, headsets and webcams. Go USB 3.0 (5Gbps) if you'll share an external drive or a fast card reader. Gaming mice at 1000Hz polling only need a tiny fraction of USB 2.0 bandwidth, so speed isn't the issue there. The KVM's emulation layer is (see the FAQ).

How you'll switch

A button on the unit is the most reliable. Hotkeys (usually a double-tap of Scroll Lock or Ctrl) are fastest once you remember them, and the TESmart supports them. A desk controller like UGREEN's puck is a good middle ground. An RF remote, like the Cable Matters one, is the best option when the switch lives behind or under the desk.

Frequently asked questions

What is the best KVM switch for two computers and two monitors?

The UGREEN HDMI KVM Switch 2 Monitors 2 Computers is the best pick for most people at $64.99. It handles two 4K 60Hz monitors and four USB 3.0 devices and ships with all the cables. Pay up for the TESmart at $199.99 only if you switch many times a day and need EDID emulation to keep your windows in place.

Will a KVM switch work with a 144Hz or 240Hz gaming monitor?

Only a DisplayPort KVM will run 4K above 60Hz. HDMI 2.0 switches like the UGREEN and TESmart cap 4K at 60Hz. The Cable Matters DisplayPort 1.4 KVM is listed for 4K at 240Hz with DSC and passes FreeSync and G-SYNC, as long as both computers have DisplayPort outputs.

Does a KVM switch add input lag for gaming?

Not to the video signal in any way you'd notice, but some KVMs can affect the mouse. Many switches emulate the keyboard and mouse so they can catch hotkeys, and that layer can drop extra mouse buttons or polling rate. For competitive play, plug your gaming mouse directly into the gaming PC and share a second mouse through the KVM.

Why do my windows move when I switch computers on my KVM?

Your KVM probably lacks EDID emulation. Without it, the computer you switch away from thinks its monitors were disconnected and rearranges your desktop. A switch with EDID emulators, like the TESmart dual-monitor KVM, keeps both computers seeing their monitors the whole time.

Can I use a KVM switch between a Mac and a Windows PC?

Yes, all three switches here are plug-and-play on macOS and Windows. Hotkeys can behave a little differently because Macs map Command and Option differently, but button, controller and remote switching work the same on both.

Bottom line

Buy the UGREEN HDMI KVM Switch 2 Monitors 2 Computers. At $64.99 it covers one or two 4K 60Hz monitors, shares a fast external drive over USB 3.0, and comes with every cable, which makes it the right switch for nearly every two-computer desk. The two exceptions are narrow: a high-refresh gaming monitor needs the Cable Matters DisplayPort 1.4 KVM, and a dual-monitor desk that switches all day is worth the TESmart's EDID emulation.
