TESmart makes KVM switches, the boxes that let you run two or more computers from one keyboard, mouse and set of monitors, along with docks, extenders and rack-mount units for IT rooms. This TESmart review draws on hands-on reviews of four different switches, a brand overview and the company's Amazon seller record to cover what works, what to watch for, prices, warranty and support. The short version: TESmart switches are reliable, well equipped and widely praised for clean, lag-free switching, but you need to pick the right model for your monitor's resolution and refresh rate, and the flagship units are expensive.

TESmart review: our verdict in brief
TESmart is a strong choice if you switch between a work laptop and a desktop, run several machines at one desk, or need a dependable switch for a studio or server rack. Reviewers consistently found switching fast and clean, with EDID emulation keeping window layouts in place. Check the specs carefully before you buy, though: some models limit the refresh rate at high resolutions, which matters for gaming monitors, and the most advanced units cost several hundred dollars.
How we researched this review
We read hands-on reviews from The Gadgeteer, The Phonograph, FunkyKit and Media Realm, each covering a different TESmart switch, a brand overview from WisePicked, and CherryPicks' profile of TESmart's Amazon store, and checked TESmart's site for current prices and support details. Two reviewers received free samples, which we note. We did not use TESmart switches ourselves, so every finding is credited to the reviewer who reported it.
What TESmart is
TESmart builds KVM switches for home offices, gamers, creators and IT departments, from simple two-computer HDMI boxes to dual- and triple-monitor DisplayPort models, Thunderbolt docks and large rack-mount units. WisePicked says the company started in 2004 and highlights its own switching technology, including a True 8K60 HDMI 2.1 engine developed with ADI that carries 48Gbps of bandwidth with variable refresh rate intact. It rated TESmart 8.8 out of 10, while noting premium pricing and setup documentation that assumes some technical knowledge.
On Amazon, CherryPicks lists 83 TESmart products with an average rating of 4.8 out of 5 from 632 feedback ratings in the past year.
The switches reviewers tried
TESmart Thunderbolt KVM Switch
This dual-monitor switch pairs a Thunderbolt 4 laptop with a second computer. The Gadgeteer priced it at $699 and found it worked flawlessly for weeks, with a well thought-out USB layout, gigabit Ethernet and EDID emulation that keeps window positions when you switch. The catch was its HDMI outputs: on a 3440 x 1440 ultrawide gaming monitor it topped out at 60 FPS, and the reviewer wished for a DisplayPort option with higher refresh rates. The review unit was a free sample.
TESmart 4K KVM Switch Type-C HDMI
This four-computer switch earned near-perfect marks. The Phonograph connected two high-end desktops, a MacBook Pro and a Surface Laptop Studio, and saw flawless 4K 60Hz output at full 4:4:4 color, no added input lag and correct resolutions when switching between machines with different displays. Its only design niggle was LED indicators that are hard to read from steep angles.
TESmart Dual-Monitor HDMI and DisplayPort KVM Switch
This compact two-computer, two-monitor switch accepts both HDMI and DisplayPort inputs. FunkyKit scored it 8.4, praising its small 599g body, support for 4K at 60Hz or 1080p at 240Hz, EDID emulation and three ways to switch (front button, remote and keyboard hotkeys). Its main drawback was the lack of USB 3.0.
TESmart HDMI KVM Switch HKS0201A2U
The basic two-computer HDMI switch is the most mixed review. Media Realm, which received a free unit, found it sturdy and responsive for switching between a Windows mini PC and a MacBook, but switching back to the Mac took almost a minute before the picture returned, and the Scroll Lock hotkeys dimmed the Mac's screen. It still considered TESmart good at hitting the sweet spot of price and features at the lower end.
The four switches side by side

| TESmart Dual-Monitor HDMI and DisplayPort KVM Switch | Two computers, two monitors; 4K@60Hz or 1080p@240Hz (FunkyKit) | HDMI and DisplayPort inputs, audio jack | Dual-monitor desks on a budget |
| TESmart HDMI KVM Switch HKS0201A2U | Two computers, one monitor; HDMI and USB-A, about US$110 (Media Realm) | Audio out, keyboard hotkeys | Simple two-PC sharing |

- High-end models support very high resolutions and refresh rates with variable refresh rate
- Generous accessories and cables included

Who should buy TESmart, and who should skip it
Buy TESmart if you share monitors between a work laptop and a personal PC, run several computers in a studio or home lab, or want a switch that keeps your windows where you left them. Use TESmart's compatibility check before buying anything expensive, and match the switch to your monitor's refresh rate.
Skip the premium lines if you only need to share one basic monitor between two computers occasionally; a cheaper switch will do. For other desk tech, our HiBy review covers audio gear, and our Meshnology review looks at radio kits for tinkerers.
Alternatives
None of our sources names specific rival brands, but WisePicked points out that cheaper KVM brands cover basic two-PC, single-monitor needs. Consider these routes instead of TESmart:
- A budget two-port KVM from another brand: choose this if you only share one monitor between two computers and do not need high refresh rates.
- A USB switch plus your monitor's own input button: choose this if your monitors already have multiple inputs and you just need to move a keyboard and mouse.
- Software that shares a mouse and keyboard across computers: choose this if each computer keeps its own screen and you only want one set of controls.
Our ratings
Overall: 4/5, because The Phonograph and The Gadgeteer found TESmart switches reliable and lag-free, while refresh-rate limits on some models and premium flagship pricing hold the brand back.
TESmart Thunderbolt KVM Switch: 4/5, since The Gadgeteer found it flawless in daily use but limited to 60 FPS on a high-resolution gaming monitor, at a high price.
TESmart 4K KVM Switch Type-C HDMI: 4.5/5, as The Phonograph measured flawless 4K output, full color and no added lag across four computers.
TESmart Dual-Monitor HDMI and DisplayPort KVM Switch: 4/5, because FunkyKit praised its flexibility and compact size but missed USB 3.0.
TESmart HDMI KVM Switch HKS0201A2U: 3.5/5, since Media Realm found it sturdy and good value but slow to restore a Mac's display.
