Resolution and refresh rate are one figure, and the switching method is the other · review
A four-computer VGA switch supplied with four combined leads and a desk controller, quoting a resolution above the usual 1080p ceiling and no refresh rate at all.
A four-computer VGA switch letting four machines share one screen and three USB 2.0 devices such as a keyboard, mouse, printer, scanner and drives; a resolution of up to 1920 by 1440 with support for a very wide screen, DDC support and automatic identification, plug and play with no driver and no external power supply; compatibility given as Windows, macOS and Linux; two switching methods, a wired desk controller and a panel button, with an indicator light showing the machine under control; and four combined leads joining VGA and USB in one, with a warning against illuminated mechanical keyboards on account of the current they draw.
That single line separates this from most of the shelf. A combined lead serves one computer, and a page that supplies as many leads as it accepts computers is a page that has thought about the first evening.
1920 by 1440 is quoted and no rate in Hz is. The two figures belong together, because a ceiling stated at one resolution and an unstated rate can be met in more ways than one. What the page does say is that the switch is the limit and not the source: the machine and the screen impose theirs on top.
The unit draws what it needs from the computers, which is why there is no brick to find room for and why the page warns against a keyboard that lights up. Both facts come from the same design decision, and the listing states them both.
Look at the keyboard already on the desk. If it is illuminated and mechanical, this is the switch to ask about first.
| Port count | Four — stated in the title and in the first bullet as four computers or laptops managed from one place |
|---|---|
| Maximum resolution | 1920 by 1440 — stated in the second bullet, which adds that a very wide screen is also supported. It is the ceiling of the switch alone; the computers and the screen each impose their own |
| Refresh rate | Not published on the listing — no figure in Hz appears in the title or in any of the five bullets, so the resolution stands without the second half of the pair |
| Video connector type | VGA — stated in the title and in the first bullet, with one screen at the output |
| Screens per computer | One — stated in the title as four computers sharing one screen |
| USB port count | Three — stated in the first bullet as three USB 2.0 devices, named as a keyboard, a mouse, a printer, a scanner and drives |
| USB generation | USB 2.0 — stated in the first bullet; no transfer rate is quoted alongside it |
| Switching method | Two — a wired desk controller and a button on the front panel, stated in the fourth bullet, with an indicator light showing which computer is under control |
| Audio support | Not published on the listing — no audio socket and no speaker or microphone connection appears in the title or in any of the five bullets |
| Cables supplied | Four combined leads, each carrying VGA and USB in one — stated in the title and described in the fifth bullet as keeping the desk tidy |

Because a switch drawing its own power from the computers has a limited amount to pass on, and an illuminated mechanical keyboard can ask for more than a plain one. The fifth bullet on this page says so directly. It is the trade that comes with a unit needing no external supply, and it is better read before ordering than discovered afterwards.
Reach. The switch can go behind the machines where the leads are short and tidy, while the control sits by the hand. On a desk with four computers that is the difference between a small movement and a stretch, and this listing supplies both methods rather than one.
7.8/ 10
The best-equipped of the VGA switches here: four leads in the box, two ways to switch and no power brick. The unpublished refresh rate and the warning about keyboards are the two lines to read before ordering.
This network and storage gear share the category and the price bracket. Only what each one states is shown; an incomplete column would mislead.
| Model | Price | Port count | Maximum resolution | Refresh rate | Video connector type |
|---|---|---|---|---|---|
| DGODRT KS204V, four-computer VGA switch with a wired desk controller | $33 | Four — stated in the title and in the first bullet as four computers or laptops managed from one place | 1920 by 1440 — stated in the second bullet, which adds that a very wide screen is also supported. It is the ceiling of the switch alone; the computers and the screen each impose their own | Not published on the listing — no figure in Hz appears in the title or in any of the five bullets, so the resolution stands without the second half of the pair | VGA — stated in the title and in the first bullet, with one screen at the output |
| CMSTEDCD GMXUS-SW219S | $17 | Two — stated in the title and in the first bullet as two computers sharing one monitor and one keyboard and mouse set | 4K — stated in the title and in the second bullet as up to 4K at 60 Hz, backwards compatible with 3840 by 2160 at 30 Hz, 1920 by 1080 at 60 Hz and 1920 by 1080 at 30 Hz. The same bullet requires that the computers and the screen support 4K themselves | 60 Hz at 4K — stated in the second bullet as a pair, which is the form in which the two figures can be read together, with 30 Hz named at the same resolution as the fallback | HDMI — stated in the title and in the first bullet, which requires an HDMI port on each computer and on the monitor and warns that conversion cables or adapters may give an unstable or flickering picture. The second bullet asks for an HDMI 2.0 lead no longer than 3.3 feet |
| DXchip KVM302DP-02 | $86 | Three — stated in the title and in the first bullet as three computers sharing two DisplayPort monitors and four USB 3.0 devices. It is the only three-computer unit on this shelf | 8K, given as 7680 by 4320 — stated in the title and in the second bullet at 30 Hz, with 3840 by 2160 at 144 Hz also named and lower resolutions supported. The same bullet states that the sources, the monitors and the DisplayPort leads must all support the figure to reach it | 30 Hz at 8K and 144 Hz at 4K — stated in the second bullet as pairs, which is the form in which the two figures can be read together. The same maker’s HDMI 2.1 unit on this shelf publishes 60 Hz at 8K and the same 144 Hz at 4K | DisplayPort 1.4 — stated in the title and in the second bullet, with two DisplayPort inputs required from each machine and two DisplayPort outputs to the screens |
| UGREEN AK700, two-computer DisplayPort switch driving two screens | $90 | Two — stated in the title and in the first bullet as two desktop computers | 8K — stated in the title and in the second bullet as up to 8K at 60 Hz, backwards compatible with 8K at 30 Hz, 4K, 1080p, 720p and 480p. It is the ceiling of the switch alone; the computers and the screens each impose their own | 60 Hz at 8K, with 8K at 30 Hz also named — stated in the second bullet as pairs, which is the form in which the two figures can be read together | DisplayPort 1.4 — stated in the second bullet; the first bullet states in as many words that this switch has no HDMI socket |
A desk running three or four machines on one screen where the switching should happen from the hand rather than from the unit, and where the keyboard is a plain one.
