splitter I purchased this VGA Splitterto drive multiple monitors from the VGA output of a 16-channel security DVR. It’s a small, flat black box with all connections on the rear, nothing on the front but a single red LED indicating it is powered up.

At this point, I’ve set it up with two monitors on outputs one and two, each on a 100 foot standard VGA cable. Fidelity is good; no hum or other interference is visible, and the resulting display is very sharp. However, my application is not as demanding in terms of sharpness as normal computer output is; I’m only using 640×400 resolution. Other reviews agree that output is sharp for computer use, and the claim in the marketing materials is that it is good up to 1920 horizontally. Odds are excellent that it will provide a sharp display in your application, but again, I can’t vouch for that, only for what I have seen.

The splitter is powered by a wall wart, so make allowance for a fat plug where the splitter is to be installed. The power supply I received has most of its bulk lengthwise, and so may fit on a power strip with other units, depending on plug orientation.

The power input jack on the splitter is a barrel type plug, so it can be easily pulled out, there is no positive lock for power. The VGA connections, both in and out, do provide standard screw-type fittings so you can securely attach all the VGA cables. So watch the power supply cable run during install for anywhere it might be subject to snags and pulls.

Gotcha #1: The splitter does not pass through or otherwise handle handle plug-n-play, so if you’re thinking about using this with Windows… there may be some issues, particularly with multi-screen monitor setups.

back Gotcha #2: The splitter’s input does not take a standard VGA cable, and does not include the cable or connector you actually need. So if you’re thinking you can use just any old VGA cable you have lying around to connect the splitter to your VGA source… no. You need a cable with a male VGA connector on one end, and a female VGA connector on the other end. These cables are not generally found just lying around; you can obtain them on Amazon under the description “VGA Extension Cables.” Another option is a VGA female-to-female gender changer tacked onto the end of a standard VGA cable (I don’t recommend this, by the way… an extension cable will provide higher signal quality and connection reliability due to the fewer number of connections.) Remember to order one or the other, and have it available at install time.

Gotcha #3: The splitter is, physically speaking, a very light device. VGA cables, on the other hand, tend to be very heavy and stiff. Consequently, the device doesn’t really want to lie on the shelf so much as just hang off the end of the cables that are plugged into it at a point in midair where the VGA cable stresses even out. I’m seeing this effect with three cables (one in, two out) so if you load it up with all five (one in, four out), I think you’d have quite a bit of stress. I used four strips of “super” Velcro, screwed to the shelf, which are holding everything where I want it very well — but keep in mind, I’m only using three of five connections.

In the end, once you work around the gotchas, the unit does the job it is supposed to do very well. I think there’s still plenty of room for improvement in ease of use, connectivity (it should really use a standard VGA cable for input), and physical stability.
