Resolution and refresh rate are one figure, and the switching method is the other · review
A four-computer switch whose inputs are of three different kinds, quoting its resolutions and refresh rates as pairs and never listing what is in the box.
Amazon.com listed it on October 26, 2026, but no current offer passed our price check, so no price is quoted. The Amazon.com page exists, but nobody was selling the unit; a listing in that state is often a third-party import.
Models on this shelf that Amazon.com did sell on that date:
A switch connecting four computers, one laptop and three desktop machines, to a single HDMI screen, controlled by one keyboard and mouse; HDMI 2.0 with 4K at 60 Hz, 2K at 100 Hz and 4:4:4 color subsampling, backwards compatible, with connectable inputs given as one DisplayPort, one USB-C and two HDMI; an EDID function that can be turned on or off, holding the screen settings and leaving the window arrangement undisturbed when machines are changed; four USB 3.0 sockets at 5 Gbps, compatible with USB 2.0 and 1.1, recognizing mice, keyboards, printers, drives, scanners and cameras; and two switching methods, a select button on the unit and a wired remote of 1.5 m (5 ft).
4K at 60 Hz. 2K at 100 Hz. Two ceilings, each with its rate attached. That is how the figures belong on the page, because a resolution quoted without a rate can be met at a rate nobody wants. Both remain limits of the switch: whatever the machine sends and whatever the screen accepts still apply on top.
One DisplayPort, one USB-C and two HDMI. This is a switch for a desk whose machines do not match, and it means the leads do not match either. Each computer needs the one its own socket takes.
A screen that vanishes when the switch moves elsewhere is the reason windows rearrange themselves. Holding its identity stops that, and this unit lets the behavior be turned off as well as on, which matters when a machine refuses to cooperate with it.
The box. A power supply and a remote are named in the title; the bullets name grades of lead to use and never say which of them, if any, is included.
Write down which socket each machine will use, then ask the seller which of those leads comes in the box. On a switch with three kinds of input, that list is the purchase.
| Port count | Four — stated in the title and in the first bullet as four computers, given as one laptop and three desktop machines |
|---|---|
| Maximum resolution | 4K — stated in the title and in the second bullet, quoted as 4K at 60 Hz with 2K at 100 Hz also named, and described as backwards compatible. It is the ceiling of the switch alone; the computers and the screen each impose their own |
| Refresh rate | 60 Hz at 4K and 100 Hz at 2K — stated in the title and in the second bullet as pairs, which is the form in which the two figures can be read together |
| Video connector type | Mixed inputs — one DisplayPort, one USB-C and two HDMI, stated in the second bullet, with HDMI 2.0 named for the switch and an HDMI screen given at the output in the first bullet |
| Screens per computer | One — stated in the title and in the first bullet, where four machines share a single screen |
| USB port count | Four — stated in the fourth bullet as four USB 3.0 sockets |
| USB generation | USB 3.0, quoted at 5 Gbps and compatible with USB 2.0 and USB 1.1 — stated in the fourth bullet, which names mice, keyboards, printers, drives, scanners and cameras as being recognized automatically |
| Switching method | Two — a select button on the unit and a wired remote of 1.5 m (5 ft), stated in the fifth bullet, with plug and play and no driver required |
| Audio support | Not published on the listing — no audio socket, no channel count and no audio format is named in the title or in any of the five bullets |
| Cables supplied | Not published on the listing as a list — the title names a power supply and a wired remote, while the second and fourth bullets tell the buyer which grades of lead to use without saying whether any of them is in the box |
| Amazon reference | B0GH7PMBP8 |
| EAN | 0740122798811 |
| On Amazon.com | Amazon.com listed it on October 26, 2026, but no current offer passed our price check, so no price is quoted. |
It holds the identity of the screen so that each computer keeps seeing one even when the switch is pointed elsewhere. Without it, machines are told the screen has gone and rearrange their windows accordingly. This listing states that the function can be turned on or off and that the window layout survives a change of machine.
They change what has to be bought. One DisplayPort, one USB-C and two HDMI inputs means each machine needs a lead matching its own socket, rather than four identical ones. It is an advantage where the machines genuinely differ and an inconvenience where they do not, and this page states the arrangement clearly enough to plan around.
7.8/ 10
The most flexible input arrangement here and the clearest way of quoting a video ceiling, held back by a page that never says what arrives in the box. Four different leads is a shopping list worth writing before ordering.
A desk where the four machines do not share a video socket between them, and where a drive has to follow whichever one is in use.

two laptops · two HDMI screens each · 4K over USB-C · seven USB sockets · Ethernet, SD and headset · 60 W charging each
A docking station that switches as well, carrying two screens, Ethernet, an SD slot, a headset jack and 60 W of charging for each laptop, and publishing no refresh rate at all.

two computers · one screen · 4K at 60 Hz · HDMI · two USB 2.0 at 480 Mbps · button or desk controller · no hotkey
The cheapest American listing on this shelf, publishing its resolution and rate as a pair and stating outright the three things it will not do: hotkeys, Mac machines, and an HDMI lead in the box.
Best for: Two Windows machines on one HDMI screen, where the switch should cost less than the cable and stay out of sight.
