#189103 - I've been using 'em too ...

The discussion on 'real' PS2 keyboards and VGA connectors reminded me of the depth of knowledge on this forum!

I've been using KVM (Keyboard - Video - Mouse) switches for years as I just don't have enough office space to put a screen on every PC I have, and because it annoys me when I think the mouse doesn't work but it's only because I've picked up the wrong mouse. My latest KVM switch provides PS2 connectors for keyboard and mouse and DVI for video. If a PC doesn't have a PS2 port, I use an adaptor, which works well enough.

The gripe with my current setup is tha on one PC, when you switch away from it, it disables it's DVI output and doesn't re-enable it when you reconnect. I think this is a 'bug' in the video card driver, but don't know what to do about it. Does anyone have any experience they could share about such gripes?

It also strikes me that it would be really, really handy if there was a KVM switch that also included an Ethernet hub and audio. Again, any thoughts?

I can't imagine anything that would work better for the ethernet segment of this problem than a switch. They're cheap, require little cabling (and that has been somewhat of a hassle with the KVM switches).

The ones I use are from Zonet. I've had little trouble with 'em ... and they're cheap. The main cost, of course, is the cabling. I think I'd be happier with something that simply talked to the PC's through a module that interfaces via ethernet or something very similar, and kept the cable length down under 40 cm. My lab is crawiling with cabling, and, though it often is neatly accommodated, each time I rearrange the internals, or externals, of a PC, the cables are a mess again. Unfortunately, this often happens when I need to "do something" and that means that the mess has to be dealt-with later, which, I assure you, is not a good thing.

The KVM switch is convenient because the need for multiple monitors, keyboards, and mice is essentially eliminated. These switches even allow my UNIX-based logic analyzer, and LINUX boxes, to share the same comfortable mouse and large monitor, yet enable me to monitor processes running on various machines without disturbing the hookups. Further, they allow me to switch between Windows versions, thereby allowing me to use software that actually works, as opposed to much of the stuff that's been sold in the last decade. It even works with DOS, and supports different monitor pixel densities on the same large-screen monitor.
