DGODRT KS204V, four-computer VGA switch with a wired desk controller 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.

By Jean-Benoit Buisson

The bottom line 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 The unpublished refresh rate and the warning about keyboards are the two lines to read before ordering.

On the listing

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.

Four leads for four machines

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.

A resolution without its pair

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.

No external supply, and what that costs

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.

Before ordering

Look at the keyboard already on the desk. If it is illuminated and mechanical, this is the switch to ask about first.

Where it holds up, and where it stops

Strengths

Four combined leads for four computers, so the box contains what the switch needs rather than half of it
Two switching methods, one of which reaches the desk, so machines can be changed without leaning towards the unit
Stated as needing no driver and no external power supply, which removes two of the things that go wrong on a crowded desk

Compromises

No refresh rate is published, so the resolution figure stands alone and cannot be read as the pair it belongs to
The USB sockets are named as 2.0 with no rate quoted, so what a drive would do between machines is unstated
The fifth bullet advises against an illuminated mechanical keyboard because of the current it draws, which is a real limit on a switch with no external supply

Specifications

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
Amazon reference	B092Q2DVC2 (same reference on 6 Amazon marketplaces)
EAN	0751031441835

The questions that come up before an order

Why would a keyboard be too much for a KVM switch?

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.

What does a wired desk controller add over a button?

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.
