The UGREEN HDMI KVM Switch is a true HDMI KVM: it routes one HDMI monitor at 4K@60Hz, four USB 3.0 peripherals and a 3.5mm audio path between two computers, with switching by front-panel button, hot-key, or an external wired remote. After five USB-only switches and two legacy VGA KVMs in this list, this is the first model that does the full KVM job on a modern HDMI desk. This UGREEN HDMI KVM Switch review covers the switching performance, display compatibility, USB and audio pass-through, build and value at around $90.

Switching Performance & Latency
The UGREEN HDMI KVM offers three switching methods: the front-panel button, a Scroll Lock hot-key sequence on the shared keyboard, and a small wired remote that sits on the desk and toggles the active host with one press. The wired remote is the standout addition — it lets the KVM hardware live under the desk where its cabling lives, with a single small selector pad on top of the desk for the user. As a true HDMI KVM the changeover routes the keyboard, the mouse, the HDMI video and the audio to the newly selected host in a single action. Expect one to two seconds for the monitor to lock to the new HDMI sync (this is the HDMI handshake, not a flaw of the switch) and the USB devices to re-enumerate. The HDMI handshake is the dominant component of the latency; the USB side is faster.
Reliability across HDMI sources is the key practical question on any HDMI KVM, and UGREEN’s design is one of the strongest in the price range. HDCP is supported transparently for protected content, EDID emulation prevents the host from losing its monitor profile during a switch, and the firmware handles modern HDMI 2.0 sources cleanly.
Display Compatibility — Single / Dual / Triple
The KVM supports a single shared HDMI monitor at up to 4K (3840×2160) and 60Hz, which requires HDMI 2.0-class hardware on the switch, the cables, and the source. The two HDMI 2.0 cables supplied in the box meet that spec, which matters because using HDMI 1.4 cables on a 4K@60Hz KVM would silently downgrade the link to 4K@30Hz. For 1080p high-refresh gaming the same HDMI 2.0 link comfortably carries 1080p@144Hz or 1440p@120Hz. This is a single-monitor KVM — there is one HDMI out, period. Buyers who need to share two or three monitors should look at the multi-monitor HDMI KVMs further down our list. For the cables themselves, see our best HDMI cables guide.
USB Pass-Through & Peripherals
Four USB 3.0 Type-A downstream ports at 5 Gbps each is generous for a KVM and is the practical advantage over the budget HDMI KVMs that ship with only USB 2.0 pass-through. The four ports handle the full modern peripheral pool — mechanical keyboard, gaming mouse, 4K webcam and a fast external SSD — without bandwidth compromises. USB device re-enumeration is the limiting factor on switch speed; with four ports active expect about a second for everything to settle on the new host, which is normal. There is also a 3.5mm audio jack on the rear for analogue speakers or a headset, routed alongside the USB and video.
Build Quality & Switching Method
The chassis is a metal-cased rectangular unit with HDMI inputs and USB-B uplinks on the rear, the four USB-A downstream ports and audio jack on the front, and the front-panel selector button alongside the active-host LEDs. The wired remote is a small pad on a 1.5m cable and uses a 3.5mm-style jack into the rear of the main unit, so the remote can be repositioned freely on the desktop. All the cables you need are in the box — two HDMI 2.0 cables, two USB 3.0 uplinks and the wired remote — which removes the typical multi-purchase headache of building out an HDMI KVM setup. UGREEN’s metal-cased build is a step up from the all-plastic chassis of the cheaper switches reviewed earlier in the list.
Use Cases — Gaming + Streaming, Home Office
This is the right KVM for the modern gaming or streaming desk where one high-quality HDMI monitor must serve two computers — a gaming PC and a work laptop, or a gaming PC and a dedicated streaming rig. The 4K@60Hz spec covers both the productivity case (one 4K monitor shared between two computers) and the gaming case (1440p high-refresh on the same hardware). The four USB 3.0 ports cover the gaming peripheral pool comfortably, and the wired remote means the switch hardware can live tidily out of sight while a small selector pad sits on the desk. For the gaming hardware on the other side, our best RTX 5070 gaming laptops guide covers the typical kit, and our Intel Core Ultra laptop guide guide covers Intel Core Ultra desktops.
Verdict
The UGREEN HDMI KVM Switch is the first true modern KVM in this list and is the right choice for two-PC HDMI desks where one shared monitor must follow the keyboard and mouse. The 4K@60Hz support is what most buyers will pay for, the four USB 3.0 ports add generous peripheral capacity, and the wired remote is a genuinely thoughtful inclusion. Every cable you need is in the box, and UGREEN’s metal build is reassuringly solid. At roughly $90 it is materially more expensive than the USB-only switches reviewed above, but the price buys the full KVM functionality — video, USB, audio — for a modern HDMI desk. It is the easy recommendation in its price tier.
Frequently Asked Questions
Does it support 4K@60Hz on the shared monitor?
Yes — the KVM and the bundled HDMI 2.0 cables support 4K (3840×2160) at 60Hz on the shared HDMI monitor. The source PCs must be capable of HDMI 2.0 output.
Does it have hot-key switching?
Yes — Scroll Lock + Scroll Lock + 1 or 2 on the shared keyboard switches to host 1 or host 2. A wired desktop remote is also included as an alternative switching method alongside the front-panel button.
How many USB peripherals can I share?
Four USB-A 3.0 ports at 5 Gbps each. That is enough for keyboard, mouse, a 4K webcam and a fast external SSD with bandwidth to spare.
Are HDMI cables included?
Yes — two HDMI 2.0 cables, two USB 3.0 uplink cables, and the wired remote are all in the box. No separate cable purchase is needed.
