IOGEAR does not sell one KVM line but six, and the right pick depends less on port count than on how many displays you run and what feeds them. Two switches with near-identical names can sit two generations apart, which is why the general KVM buying guide only gets you so far.
Four variables decide it. Display count, one, two or three. Video generation, Full HD, 4K30 or 4K60. Peripheral bandwidth, USB 2.0 against USB 3.x at 5Gbps. And whether a USB-C laptop needs the switch itself to charge it. IOGEAR answers the first three thoroughly and the fourth only on a few dock-style models.
The catalog also keeps legacy and current side by side. VGA, DVI and older HDMI platforms remain listed long after a faster platform replaces them, and the "-UN" suffix marks a kit with bundled conversion hardware rather than a newer video engine. Reading the model number tells you the family, not the specification.
What IOGEAR's KVM Range Is Built Around
The range reads like an enterprise supplier's catalog, not a gaming brand's. The desktop collection tracks dozens of listings, plus separate cable, rackmount, secure and LCD-console catalogs.
Three themes run through it. The first is IT-channel depth: the four-port desktop KVMPs, the rack switches and the secure units carry TAA compliance, and the rack line cascades to hundreds of systems through daisy-chaining. The second is an HDMI-first desktop focus, with DisplayPort fully covered but never the lead story. The third is a narrow high-refresh footprint, essentially one gaming model, with everything else centered on 4K60 productivity.
Two naming traps catch buyers. Model numbers do not count displays: the GCS1932H and GCS1932 are single-display switches, and the "2" says nothing about monitor support. And where an older unit and a newer one overlap, IOGEAR rarely discontinues the old one, so "still sold" and "current generation" mean different things.
Fixed-Cable and Basic Desktop Switches
This is the budget tier: a switch, a fixed cable bundle, and shared keyboard and mouse. Video tops out low, and none of these models provides laptop charging.
GCS32HU. A two-port HDMI switch with fixed host cables, sharing one USB keyboard and mouse across two computers. It stops at 1920×1200, so it belongs on a Full HD desk, not a 4K one. Still active and positioned as IOGEAR's basic HDMI staple.
GCS62HU. An older two-port HDMI cable KVM, also Full HD-class, still listed in the 2026 cable catalog. It is the clearest illustration of the brand's habit of keeping legacy hardware on the shelf. A new 4K desk should skip it.
GCS92HU. The current budget 4K HDMI switch and the natural starting point. Two HDMI host inputs, one HDMI output at 4096×2160 @ 60 Hz, plus 2560×1440 @ 144 Hz. USB 2.0 keyboard and mouse, shared analog speaker and microphone jacks, a wired remote pushbutton, and fixed 48-inch host cables. Firmware v1.2.114, three-year warranty, Windows 10/11, macOS 10.13+ and Linux.
GCS52DP. A two-port DisplayPort cable KVM on DisplayPort 1.2 with HDCP, 4096×2160 @ 60 Hz, and 7.1/2.1 digital audio carried over DisplayPort. Bus-powered. One caveat: older documentation for this SKU listed 4096×2160 @ 30 Hz, and IOGEAR has not published a hardware revision that maps the change, so a used or new-old-stock unit should not be assumed to reach 4K60.
GCS62DP. An older DisplayPort cable KVM, still active but best described as legacy-current. Its four-port track record sits behind the GCS1932 in every meaningful spec, so it only makes sense when a deployment already standardizes on it.
GCS82DPC. The hybrid worth knowing about. Computer 1 connects by DisplayPort and USB-A, computer 2 by USB-C with DisplayPort Alt Mode, and both share one DisplayPort console output at 4096×2160 @ 60 Hz. Analog audio and microphone, a wired remote, four-foot host cabling and a six-foot remote. There is no Power Delivery passthrough, so treat it as a switch, not a charging dock.
The 4K60 Single-Display KVMP Line
The KVMP label is where IOGEAR adds a shared USB peripheral hub and audio routing to the switch. This is the core of the range, and it is where the 4K30-versus-4K60 distinction matters most.
| Model | Hosts | Video | Peripherals | Notes |
|---|---|---|---|---|
| GCS1902 | 2 x DisplayPort | 3840×2160 @ 30 Hz | USB 3.x hub, audio | TAA, 4K30 tier |
| GCS1904 | 4 x DisplayPort | not listed | USB 3.x hub, audio | TAA, support files updated 2025 |
| GCS1902-UN | 2 x DP/HDMI (universal) | 3840×2160 @ 30 Hz, 2560×1600 @ 60 Hz | USB 3.x hub | Bundled conversion hardware |
| GCS1932 | 2 x DP 1.2 | 4096×2160 @ 60 Hz | USB 3.1 Gen 1 (5Gbps), audio and mic | Firmware 1.1.107 (2025) |
| GCS1934 | 4 x DP 1.2 | 4096×2160 @ 60 Hz | USB 3.1 Gen 1 (5Gbps), audio | TAA |
| GCS1932H | 2 x HDMI | 4096×2160 @ 60 Hz | USB 3.0 (5Gbps), dedicated K/M, analog audio | HDMI 2.0-class |
| GCS1934H | 4 x HDMI | 4096×2160 @ 60 Hz | USB 3.x (5Gbps), EDID retention, RS-232 | TAA |
The GCS1902 is the trap in this table. It carries a current price tag and a KVMP feature set, but its DisplayPort ceiling is 4K30, which is why the GCS1932 is the better step-up for a modern single-display workstation. The "-UN" version of the GCS1902 does not change that: the suffix adds DisplayPort-to-HDMI conversion hardware for connector mismatch, and the base switch keeps its 4K30 ceiling.
Between the two 4K60 generations, the choice is peripheral bandwidth and control rather than resolution. The GCS1932 and GCS1934 share two 5Gbps USB 3.x ports and add microphone support, while the newer GCS1904H and GCS1922H sit below them with USB 2.0 sharing. The H-suffixed GCS1932H and GCS1934H bring the same workstation feature set to HDMI desks, and the GCS1934H adds EDID retention and RS-232 control for rack-adjacent installs.
One operational note applies across the DisplayPort family. Switching the keyboard and mouse is near-instant; reacquiring the display is not. Reports around these models describe slow transitions, monitors failing to wake, resolution changes and moved windows after a switch. That behavior traces to the whole chain, the KVM, GPU driver, monitor firmware, link training, adapters and cable quality, but it recurs often enough that it should shape expectations. IoGear's Video DynaSync, present on the H-series and several workstation models, stores monitor identification so the inactive computer still sees a display, but it is not the same as the full-time EDID retention that specialist brands market.

Dual-View and Triple-View Workstation KVMs
This is where installation mistakes are made. A dual-view KVM routes two video signals per computer; it does not manufacture a second display stream from a laptop that supplies only one. Every model below requires two independent video outputs, or a dock that provides them, from each connected machine.
| Model | Hosts | Displays | Per display | Peripherals |
|---|---|---|---|---|
| GCS1922H | 2 | 2 x HDMI | 4096×2160 @ 60 Hz (also 5120×1440 @ 60 Hz) | USB 2.0, analog audio, Video DynaSync |
| GCS1904H | 4 | 1 x HDMI | 4096×2160 @ 60 Hz (also 5120×1440 @ 60 Hz) | USB 2.0, audio, Video DynaSync |
| GCS1942H | 2 | 2 x HDMI | 4096×2160 @ 60 Hz | USB 3.x hub |
| GCS1944H | 4 | 2 x HDMI | 4096×2160 @ 60 Hz | USB 3.x hub |
| GCS1942 | 2 | 2 x DisplayPort | 4096×2160 @ 60 Hz | USB 3.x, MST, DP++, independent KVM/USB/audio focus |
| GCS1944 | 4 | 2 x DisplayPort | 4096×2160 @ 60 Hz | USB 3.x |
| GCS1964 | 4 | 3 (DP host, HDMI console) | 4096×2160 @ 60 Hz | USB 3.x, 7.1 audio, Video DynaSync |
| GCMS1922 | 2 | 2 x HDMI out (DP in) | 4096×2160 @ 60 Hz | USB 3.1 (5Gbps), audio mixer |
The GCS1922H and GCS1904H are the value entry points, both carrying USB 2.0 sharing and Video DynaSync at a 4K60 ceiling. The GCS1942H and GCS1944H keep the same video specification but add a USB 3.x hub, which is the upgrade that matters if shared SSDs or capture devices ride on the switch. The DisplayPort GCS1942 and GCS1944 add MST, DP++ conversion support and independent KVM, USB and audio focus, so you can move the video to one machine while the keyboard stays on another.
The GCMS1922 is not simply an updated GCS1942. It is a matrix switch: one mode drives both monitors from a single computer, the other shows both computers side by side, with a crossover mouse that moves control across displays. That makes it relevant for trading desks, monitoring stations and test benches, where keeping two machines visible at once is the whole point.
The GCS1964 sits at the top with three monitor outputs from four hosts, DisplayPort on the host side and HDMI-compatible console outputs. Its included cable set covers only two of the four computers; a full build needs additional cables. Across this family, expect the longest display handshakes of any IOGEAR product. Some reports describe re-sync times measured in tens of seconds in complex triple-monitor setups, which is why the dual-monitor KVM roundup treats EDID behavior as a first-class selection criterion.
USB-C and Docking KVMs
"USB-C KVM" is not shorthand for "one-cable dock." Only two models in this family handle meaningful laptop charging, and their limits differ sharply.
| Model | Hosts | Video | USB | Power Delivery |
|---|---|---|---|---|
| GCS72CC | 2 x USB-C (DP Alt Mode) | DisplayPort output, 4096×2160 @ 60 Hz | Console K/M and peripheral share | None advertised |
| GCS1602CC | 2 x USB-C (DP Alt Mode or Thunderbolt) | DisplayPort 1.4 output, 4K60 | 4 x USB-A 3.2 Gen 1 (5Gbps) | Port 1 up to 100W, Port 2 up to 5V/3A |
| GCS1602CCKIT | 2 x USB-C | HDMI 4K60 via bundled DP-to-HDMI adapter | 4 x USB-A 3.2 Gen 1 (5Gbps) | Port 1 up to 100W, Port 2 up to 5V/3A |
| GUD3C04 | 2 x USB-C | HDMI 1.4b, 3840×2160 @ 30 Hz (1080p from tablets) | 2 x USB-A 3.1 Gen 1 (5Gbps) | Port 1 75W, Port 2 up to 10W |
| GCS1953 | 1 x USB-C + 2 x DisplayPort | DisplayPort output, 4096×2160 @ 60 Hz, DP 1.2 | 2 x USB 3.x (5Gbps) | Up to 45W, MST for a second DP display |
The GCS1602CC, sold as Access Pro+, is the clearest choice for two USB-C laptops that need shared peripherals and substantial charging. Host port 1 passes up to 100W, host port 2 tops out at 5V/3A, and both hosts need DisplayPort Alt Mode or a compatible Thunderbolt connection. It runs driverless on Windows 10/11, macOS, iPadOS and Android, lists MacBook Air and MacBook Pro including M1, M2 and M3 generations, and quotes a switching time around three seconds. One support caveat matters: IOGEAR's own guidance warns against arbitrary video conversion adapters on the base unit, yet the GCS1602CCKIT officially bundles IOGEAR's GDPHD4KA DisplayPort-to-HDMI adapter. The bundled adapter is presumably validated where third-party ones are not.
The GCS1953 is a different proposition, mixing one USB-C host with two DisplayPort hosts on a single DisplayPort monitor. Its USB-C Power Delivery tops out at 45W, which is modest for a large MacBook Pro, and its MST capability is far more useful on Windows than on macOS, where independent extended desktops over MST are not supported. A single USB-C connection through this switch does not guarantee two independent external Mac displays.
The GCS72CC is bus-powered and advertises no significant laptop charging, so it fits two USB-C laptops that already have their own power arrangement. The GUD3C04 predates it and reflects an older generation: HDMI 1.4b output, 4K30 laptop video, and a documentation discrepancy between 75W and 85W that is safest read as 75W. For most modern buyers the GCS1602CC is the better target. If your goal is a single box that handles video, USB and charging together, the docking stations with built-in KVM roundup covers the tier directly above this one.

The Gaming KVM
IOGEAR sells exactly one high-refresh switch, and it is a deliberate outlier.
The GCS1337, part of the Nexus line, is a three-port HDMI gaming KVM built for PC and console switching. It handles 4K60, 1440p up to 144 Hz and 1080p up to 240 Hz, and its USB 3.2 Gen 1 hub runs at 5Gbps with dedicated controller ports. Keyboard and mouse handling is designed to preserve vendor software compatibility, and the unit supports high-DPI, 1000Hz-class gaming peripherals, RGB controls and game-audio EQ.
The dedicated controller ports are specialized rather than general-purpose USB, so do not assume a webcam or headset behaves the same way on them. If your priority is refresh rate rather than port count, the 4K and high-refresh KVM roundup is the better place to compare across brands, because IOGEAR's high-refresh catalog begins and ends here.
Rack, LCD-Console and Secure KVMs
These are local-console products, not KVM-over-IP. That distinction matters: nothing in this section gives you browser or network access, and a port count does not imply multiple simultaneous users. One local console controls many computers.
| Model | Form | Hosts | Video | Notes |
|---|---|---|---|---|
| GCS1808H | 8-port rack, 17-inch chassis | 8 direct, cascades to 512 | 1920×1200 / 1080p | USB 2.0, audio, TAA |
| GCS1808HKITU | Same plus cable bundle | 8 direct | 1920×1200 / 1080p | Includes 8 x 6-foot USB/HDMI cable sets |
| GCS1816H | 16-port rack | 16 direct | 1920×1200 / 1080p | USB 2.0, audio, TAA |
| GCS1816HKITU | Same plus full kit | 16 direct, cascades to 256 | 1920×1200 / 1080p | Full cable bundle |
| GCL1908W | 8-port LCD console | 8 direct, cascades to 128/256 | Panel 1366×768 @ 60 Hz | Integrated 18.5-inch LCD, keyboard and touchpad |
| GCS1418TAA4C | Secure, single view | 8 | 3840×2160 @ 30 Hz | NIAP PP4.0, TAA, CAC |
| GCS1428TAA4C | Secure, dual view | 8 | 3840×2160 @ 30 Hz | NIAP PP4.0, 16 host DP connectors |
The GCS1808H and GCS1816H are 1080p/1920×1200 devices, and that ceiling is intentional. Their purpose is local console access for BIOS work, provisioning, dead networks and emergency recovery, where resolution is not the constraint. The KITU variants cost more mainly because they include every host cable set, which for an IT buyer is often worth more than any specification bump. For real remote administration, these belong alongside iDRAC, iLO or IPMI, not instead of them.
The GCL1908W folds an 18.5-inch LCD, keyboard and touchpad into the same unit as an eight-port KVM, with an integrated panel at 1366×768. Its value is rack density and always-available console access, not image quality.
The secure family, GCS1418TAA4C and GCS1428TAA4C, is a separate category rather than a premium consumer option. Both carry NIAP Protection Profile for Peripheral Sharing Device v4.0 certification, TAA compliance, isolated per-host channels, unidirectional data-flow controls and dedicated CAC or biometric connections. Normal keyboard hotkeys and OSD switching are deliberately removed; selection happens by physical button or an approved remote. That absence is a security requirement, not a missing feature. The supporting families here are IOGEAR's direct peers to ATEN, Raritan, Avocent and StarTech, and the rack and server KVM roundup covers that broader field.

IOGEAR vs the Competition
The picture changes by tier, and it is rarely a clean win.
| Tier | IOGEAR's strength | Where competitors press |
|---|---|---|
| Budget cable KVM | Predictable documentation and support | CKL and generic brands pack more ports and features per dollar |
| Mainstream 4K60 | Broad HDMI and DP selection, cables usually included | TESmart's dual-display line leads on EDID emulation |
| High refresh | One gaming model (GCS1337) | Level1Techs runs DP 1.4 at 4K120-class; TESmart sells 4K144 and 8K |
| EDID-critical desks | Video DynaSync on selected models | ConnectPRO markets full-time EDID and DDM explicitly |
| USB-C hybrid | GCS1602CC brings 100W PD and four USB-A ports | TESmart sells richer Thunderbolt and hybrid docks with Ethernet and dual displays |
| Rack and public sector | 8/16-port, LCD and TAA breadth | StarTech, ATEN, Raritan and Avocent at the very top end |
| Secure KVM | NIAP PP4.0, CAC and TAA models | Security specialists with deeper certification portfolios |
Two conclusions fall out of that table. First, IOGEAR's best value is support, firmware availability and the TAA, secure and rack breadth that budget KVM brands simply do not field. Second, where display state retention is the central requirement, IOGEAR is not the strongest choice; ConnectPRO's full-time EDID model and TESmart's EDID-equipped dual-display hardware both target that problem more directly. If you are weighing IOGEAR against the wider market, the general KVM switch guide and the two-computer setup guide place these models in context.
Which IOGEAR KVM Should You Buy?
Match the model to the workstation, not to the biggest spec sheet.
| Your setup | Pick | Why |
|---|---|---|
| Two HDMI computers, one 4K monitor, budget | GCS92HU | 4K60 HDMI with audio and a wired remote |
| Desktop plus USB-C laptop, mixed connectors | GCS82DPC | One DP host and one USB-C DP Alt Mode host share a display |
| Two DisplayPort computers, single 4K60 monitor | GCS1932 | DP 1.2, 4K60, 5Gbps USB and microphone |
| Four HDMI computers with shared fast peripherals | GCS1934H | 4K60, USB 3.x hub, EDID retention, RS-232 |
| Two computers, two monitors, HDMI | GCS1942H | Dual-view with a 5Gbps hub |
| Two computers, two monitors, DisplayPort | GCS1942 | Dual-view, MST, independent KVM/USB/audio focus |
| Two computers you want visible at once | GCMS1922 | Matrix mode shows both machines side by side |
| Four computers, three monitors | GCS1964 | Triple-view; budget for extra cables |
| Two USB-C laptops needing real charging | GCS1602CC | 100W on Port 1, four 5Gbps USB-A ports |
| PC and console, high refresh | GCS1337 | 4K60, 1440p144 and 1080p240 |
| Server room, local console | GCS1816HKITU | 16 ports with a full cable bundle |
| Classified or government desk | GCS1428TAA4C | NIAP PP4.0 dual-view secure switching |
Before buying any multi-monitor model, confirm that each computer can supply the required number of independent video signals. On macOS, check the exact chip's external display limit, because no KVM can override it, and normal DisplayPort MST does not deliver independent extended desktops on Apple hardware. The Mac dock guide covers those limits in detail.
Conclusion
IOGEAR's KVM range rewards careful reading rather than brand loyalty. The GCS92HU is the correct budget entry for a 4K HDMI desk, the GCS1932 and GCS1934 carry the single-display DisplayPort workstation, the GCS1942 and GCS1944 handle dual display, and the GCS1602CC is the one model in the family that combines USB-C switching with genuinely useful laptop charging. Above that, the rack, LCD-console and NIAP-certified secure units extend into territory most consumer KVM brands never enter.
Two limits should shape the decision. IOGEAR is a 4K60 productivity brand first, so high-refresh gaming buyers have a single option, the GCS1337, and should compare across brands before committing. And where zero desktop rearrangement across every switch is the top requirement, full-time EDID solutions from ConnectPRO and TESmart target that specific problem more directly than IOGEAR's Video DynaSync.
For a conventional office, IT or multi-system desk that needs predictable documentation, TAA options and a clear decision path, the range delivers. For everything around it, the 4K and high-refresh roundup, the dual-monitor guide and the rack KVM guide fill in the cross-brand picture.
