TESmart's KVM range reads like a serial number, and the number is the spec sheet: the model code names the video inputs, how many computers and monitors the switch serves, and which tier it belongs to. A two-computer, two-monitor desk running HDMI-only machines starts at the HKS202-E23; the same desk with a Thunderbolt laptop and a desktop lands on the HDC202-X24. If you are choosing between brands rather than within one, our best KVM switches for two computers roundup covers the wider field.

Two things narrow the choice before any spec comparison is useful. The first is a rule Tesmart's own listings sometimes bury: a dual-monitor KVM needs two video outputs per computer, one for each monitor, and it cannot manufacture a second display from a single port. The second is the host hardware. A base Apple silicon laptop drives one external display natively, a laptop whose USB-C port lacks DisplayPort Alt Mode cannot feed a USB-C KVM at all, and refresh rates above 4K60 depend on DisplayPort stream compression being available at every link in the chain.

Across the range Tesmart documents a broad ladder, from a 4K60 HDMI starter to a four-computer DisplayPort 1.4 switch and a pre-order Thunderbolt 4 model. Its own pages are not always consistent: the same product can be listed as USB 3.0 in one table and USB 3.2 Gen 1 in another, and a few refresh-rate figures conflict between a product page and the lineup article. The model code printed on the retail box is the more dependable reference.

How TESmart's Model Codes Work

Every Tesmart KVM name is assembled from three blocks: video inputs, computer and monitor counts, then a tier suffix. Read left to right and the product is fully described.

A few traps sit inside the pattern. The "KS" pair in the middle is constant. The digits after it describe computers and monitors, not ports: a 202 is two computers and two monitors, a 203 is two computers and three monitors. The suffix sets the USB generation and the video ceiling, so an E23 and a P23 with identical video differ mainly in the shared USB hub. The M23 and M24 codes are not interchangeable across families either: confirm the model number on the listing rather than assuming it from the series name.

The Core Rule: One Video Output Per Monitor, Per Computer

A dual-monitor KVM does not split one video signal into two displays. It needs a separate video path for each monitor, on each computer, which is why the HDK202 and DKS202 families ask for two video cables per machine and the triple-monitor DKS203-M24 asks for three. The switch selects between two complete sets of signals; it does not multiply them. The distinction matters most for anyone new to switch topology, which our explainer on what a KVM switch is and how it works covers in full.

Tesmart's dual-monitor HDMI models also ship with two display modes. Display Mode 1 puts one computer across both monitors. Display Mode 2 gives each computer its own monitor. EDID emulation, the feature that keeps a monitor's identity alive so window and icon layouts survive a switch, is active on the HKS202 pair only in Display Mode 1. A desk that runs one computer per monitor therefore loses that protection, and it is the single most common surprise with this class of switch, as our dual monitor KVM roundup notes.

Entry Tier: HKS202-E23 and HKS202-P23

These are the two-HDMI, two-monitor switches, and they share their video section entirely.

What separates the two is the shared hub. The E23 shares USB 2.0; the P23 shares USB 3.0 at 5 Gbps, adds a front USB-A charging port and supports hot-plug. Check the HKS202-E23 on Amazon Check the HKS202-P23 on Amazon

Neither model provides PD charging to a laptop, so a laptop on this switch keeps its own power supply, and neither has shared Ethernet. The E23 switches by front button, infrared remote or hotkeys (Scroll Lock by default, or Right Ctrl), and Right Alt twice moves keyboard and mouse focus in Display Mode 2. The P23 adds mouse-wheel switching. Both boxes include two KVM cables, two HDMI cables, an infrared remote and a 12 V adapter; monitor cables are not included, and Tesmart recommends keeping them at 3 m or shorter. The E23 documents a five-year warranty with registration and a 30-day return window.

USB 2.0 is the practical limit to weigh here. A webcam, a capture card or an external DAC on the E23's shared hub runs into the 480 Mbps ceiling, so the P23's 5 Gbps hub is the version to take if those peripherals matter.

HDMI + DisplayPort: The HDK202 Tier

For desktops whose graphics card exposes one HDMI and one DisplayPort, the HDK202 family feeds each computer with one of each and drives two HDMI monitors. Check the HDK202-P23 on Amazon

The E23 variant shares USB 2.0; the P23 shares USB 3.0. Both run 3840 × 2160 at 60 Hz with 4:4:4 colour, HDR10 and HDCP 2.2, and the specs also list 3440 × 1440 at 100 Hz. The point of this tier is cable economy: it avoids stacking a DisplayPort-to-HDMI adapter on one input. Our HDMI KVM roundup covers the adapter angle in more detail.

8K and High Refresh: The M24 Tier

The M24 suffix marks Tesmart's master tier: HDMI 2.1 or DisplayPort 1.4 inputs and headline figures of 8K60 and 4K144 and above. Three models sit here and they serve different desks.

The HKS202-M24 is the HDMI-only version, with USB 3.0 and an 8K60 listing. Check the model number on the page before buying. Check the HKS202-M24 on Amazon

The HDK202-M24 takes one HDMI 2.1 and one DisplayPort 1.4 per computer and outputs to two HDMI 2.1 ports.

The DKS202-M24 is the all-DisplayPort equivalent, aimed at desktop graphics cards.

Two caveats apply across the M24 tier. The 8K60 and 4K144 figures depend on DisplayPort stream compression being available at every link: the graphics card, the cable, the monitor and the switch all have to support it, and Tesmart's own blog concedes that dual 8K60 is not guaranteed. The DKS202-M24 is listed at both 4K144 and 4K165 with DSC, and on the HDK202-M24 an unusual monitor EDID or an AUX failure can cause a misread. The DKS202-M24 is also positioned for desktops, with a laptop plus desktop setup directed to a direct USB-C-to-DisplayPort connection instead. Our 4K KVM switch roundup compares this tier against other brands.

Triple Monitor and Four-Computer Models

The top of the range splits between three-monitor dual-PC switches and four-computer units.

The four-computer DisplayPort models are the ones worth singling out: the USB and audio focus lock keeps a headset and a set of peripherals on one computer while the video focus moves to another, and the auto-sensing Gigabit Ethernet shares one uplink. The DKS203-M24 is desktop-oriented in the same way as the DKS202-M24, so a laptop-driven triple-monitor desk belongs in the HDC family instead. On the HKS401 series, Tesmart's own comparison tables do not always separate the M23 and M24 codes, so match the model number on the listing.

Laptop-Facing Models: HDC202, CKS202 and HDC203

This is the tier most people need, and the one where the host hardware, not the switch, sets the ceiling.

The HDC202-P23 pairs a USB-C laptop on PC 1 with a desktop on HDMI and DisplayPort on PC 2, and drives two monitors. It shares USB 3.0, charges the laptop at 60 W, carries Gigabit Ethernet and supports EDID. The laptop port uses DisplayPort Alt Mode and MST, so the laptop has to expose video over USB-C. Check the HDC202-P23 on Amazon

The CKS202-P23 is the two-laptop equivalent: two USB-C computers sharing two monitors over MST, with dual 4K60 output, EDID, 60 W charging per laptop, Gigabit Ethernet and USB 3.0. Both USB-C ports must be Thunderbolt or DisplayPort Alt Mode.

The HDC203 range uses DisplayLink instead of MST, and it targets exactly the case that breaks elsewhere: a base-chip MacBook that needs two or three external displays. It offers 4K60 on three outputs, MST and EDID, 100 W USB-C power delivery, Gigabit Ethernet and USB 3.0. The trade-off is the DisplayLink transport itself, which needs a driver on each computer and adds a small amount of latency. Check the HDC203 on Amazon

The HDC202-X24 is the Thunderbolt 4 version for one Thunderbolt laptop plus one desktop. PC 1 runs Thunderbolt 4 at 40 Gbps with 60 W charging; PC 2 uses HDMI and DisplayPort. It carries EDID, Gigabit Ethernet, four USB 3.0 ports plus USB-A and USB-C 3.2 Gen 2 ports, fan cooling and an aluminium chassis. Its dedicated Thunderbolt expansion port works only with PC 1, and EDID keeps window layouts intact when switching. Check the HDC202-X24 on Amazon

Apple silicon decides this tier more than any specification. Base M1 and M2 MacBooks drive one external display natively, and macOS does not use MST to split a single stream into two extended desktops, so an MST-based dual-monitor switch will mirror on those machines. A Pro or Max chip, or the DisplayLink route, is what produces independent displays. Our KVM roundup for Mac and Mac Mini works through the chip-by-chip limits.

Thunderbolt 4 Models: TKS202-X4 and THK401-X4

Tesmart's Thunderbolt entry is two models, and both come with a caveat worth stating plainly.

The TKS202-X4 handles two computers and two displays with a Thunderbolt 4-compatible link built on dual Intel JHL8440 controllers, 40 Gbps per link, 60 W charging to each computer, USB sharing at 10 and 5 Gbps, Gigabit Ethernet, microphone and L/R audio, and an infrared remote. Tesmart lists it as not yet Intel-certified for Thunderbolt, and it sits on pre-order with shipping quoted for the end of October. Its display figures also conflict: the collection page lists up to 5K120 or dual 6K60, while a product listing says up to 5K60 for an Apple Studio Display, and no EDID behaviour is stated. Check the TKS202-X4 on Amazon

The THK401-X4 is the four-input, one-display variant, with one Thunderbolt 4 input and the rest HDMI, 40 Gbps and 60 W power delivery. It is also uncertified. Check the THK401-X4 on Amazon

EDID, Hotkeys and USB: What to Expect Across the Line

A few behaviours repeat across the whole catalogue and are worth knowing before the first switch press.

EDID emulation and wake behaviour are different things. EDID keeps a monitor's identity alive so windows and icons stay put when you switch, but it is not a wake signal. When a monitor stays dark after a switch, Tesmart traces it to hot-plug detect, DisplayPort link training or a monitor's deep-sleep mode rather than EDID, and names the DKS202-M24 and DKS402-M24 as EDID helpers that do not fix a link-training or hot-plug failure upstream. Disabling a monitor's automatic source detection and power-saving mode, then re-plugging the display, is the usual first fix.

Flicker and dropped refresh rates trace back to bandwidth. The documented causes are a resolution or refresh rate beyond what the chain supports, G-Sync or FreeSync running alongside HDR, a cable that is too long, and hot-plugging an input after a switch. Turning off HDR and variable refresh to test, and shortening the cable, isolates the cause quickly.

Hotkeys need a wired keyboard on the dedicated console port. The M24 models and the DKS family use Right Ctrl twice followed by a command, mouse-wheel switching is off by default, and Bluetooth keyboards are not supported at all. The E23-class HDMI models default to Scroll Lock or Right Ctrl, with Right Alt twice moving keyboard and mouse focus in Display Mode 2. When a mechanical keyboard repeats or drops input on the console port, Tesmart provides a legacy emulation mode for exactly that. Our guide to KVM keyboard shortcuts lists the common hotkey sets by vendor.

USB topology is the last shared constraint. A KVM plus a hub plus a dock can exceed the USB hub-depth limit, a failure reported specifically on Apple silicon, so removing an intermediate hub and testing the dock directly against the monitor is the first diagnostic. The KVM installation and topology guide walks through the same order of checks.

TESmart vs the Alternatives

Against the wider KVM and docking market, two things stand out.

The code-driven naming is genuinely useful, the lineup reaches 8K60 and 4K144 tiers, and the four-computer DisplayPort switches add USB and audio focus lock for a multi-computer desk.

The gaps are certification and consistency. The Thunderbolt 4 models have not completed Intel certification, and the macOS story leans on DisplayLink, which needs a driver and adds latency.

If a driverless dock-plus-KVM is the priority, the answer sits outside this brand. Our IOGEAR KVM guide, Plugable dock guide and CalDigit dock guide cover the nearby alternatives, and the best KVM switches roundup compares the field. If a four-computer, three-monitor DisplayPort switch with focus lock is what the desk needs, Tesmart is one of the few brands that builds one.

Frequently Asked Questions

Conclusion

Tesmart's range rewards a five-minute read of the model code before anything else. Work out how many video outputs each computer can produce and whether the laptop carries DisplayPort Alt Mode or Thunderbolt, and the tier follows: HDMI 4K60 for two HDMI desktops, HDMI plus DisplayPort for mixed graphics outputs, M24 for high refresh, DKS for DisplayPort desktops, and HDC or CKS for laptops.

Two limits run across the catalogue. A base M1 or M2 MacBook will not drive two external displays through an MST-based switch, which is why the DisplayLink HDC203 models exist. And the Thunderbolt 4 models have not completed Intel certification, which matters for a certified Thunderbolt workflow.

For a two-desk, two-monitor setup, the HKS202-P23 is the balanced starting point: the same 4K60 video as the entry model with a 5 Gbps USB hub instead of USB 2.0. → Check the current price of the HKS202-P23 on Amazon
