Default recommended monitor switch for laptop or desktop selection

I recently upgraded my monitor and I would like to allow not only use of
my desktop, but my laptop as well. All have standard VGA ports. What
would be a decent, cheap switch to use? Once upon a time, I used a
mechanical switch that rotated 4 positions to enable use of any 4
computers with one monitor, but over time colors would change as there
started to be intermittents since it was mechanical, so hoping there's a
cheap electronic switch these days. Thanks.

Try a google search for KVM switch tom's hardware. There are several
threads on Tom's site, stuff there always seemed believeble to me.

Prices vary alot.

what you're looking for is a kvm, but don't waste your time or money.

you're just asking for problems, especially if you're going to use vga,
which has been obsolete for *years*. these days, it's all dvi, hdmi,
displayport and/or thunderbolt.

20" displays can be had for around $100 and you aren't likely to find a
quality digital kvm for much less than that, if you can at all.

some displays have multiple inputs, which would eliminate a kvm, but i
assume your display does not or you'd not be asking how to set it up.

another option is use screen sharing software, which can either be via
vnc or it can create a virtual screen to be used directly. vnc is free,
while virtual display software is relatively cheap.

Some time ago, I had two computers that I wanted to use with one set of
monitor, keyboard, and mouse. I used a KVM ("Keyboard, Video, Mouse")
switch with good results. In my case, one computer was running Win95,
the other Win98 (I did say "Some time ago"!).

The switch was activated by a key combination. You will want to make
sure that the required key combination is not something you already use.
IIRC, mine used CTRL-PrintScreen.

The system worked well, and the gadget cost around $40.

In your case, since you want to switch only a monitor between two
computers, I don't think a KVM switch would work. But anyone who sells a
KVM switch probably sells a monitor switch, so starting your search
there will probably work. Surely there is an electronic version of your
mechanical switch.

I've been sharing a monitor, keyboard and mouse between two computers
for many years.

The mechanical switch type gave ghosting so if they make such a thing
anymore don't get it.


The one I use is a Tripp-Lite

but at any rate, I would not "cheap out" on it

What I did with mine was to use the VGA output from one PC, and the DVI
output from another, and use the monitor input switching to select which
to display. Noted that both of your devices are VGA, but I see that
Amazon lists VGA-to-DVI adapters. I've not looked into the detail, but
perhaps that offers a solution?

One connecting directly, the other via the VGA-to-DVI adapter, and use
the electronic switching in the monitor?

those are expensive because it needs to create the digital signals from
the analog input and will obviously never be as good as digital
directly from the computer, which any computer made in the past 5 years
should have, probably even longer than that.

vga is obsolete. it dates back to the 1980s. time to move on.

Amazon lists several VGA switches. Mr Baxter mentions past bad
experience with mechanical switches, which can/will happen. But the
Amazon switches are in the $8-$15 range. I say, buy a couple of them and
consider them to be consumables.

Amazon also lists many VGA to DVI adapters, in similar price ranges.

that is a mechanical switch and it's junk.

the very first review states;
Unfortunately this VGA selector switch will not work
with modern computer video cards because it does not
switch the VGA Monitor identification signal lines.

another review:
I didn't look at previous reviews. The resolution data is not passed
on; worthless.

Amazon also lists many VGA to DVI adapters, in similar price ranges.


no they don't.

anything in that price range is a dvi-vga adapter, which is easy:

going the *other* way, vga-dvi, is not as simple and not as cheap. it
requires generating a proper dvi signal from the analog input and the
results don't look that good. it also requires external power for the
converter board.

the real question is why anyone is using vga in 2015. it's obsolete.

People are still using it because it is still available, it still fills
the needs of many people, and it will be around for quite some time.

I just treated myself to a new TV set, because the old 21" analog CRT TV
in my living room failed. The new 32" LCD LED set has among it's
connections... wait for it... VGA. Of course, I don't care that it has a
VGA input; I'm using the RF "F" barrel connection to hook up my antenna
on the roof.

I realize that in your world, everyone must do exactly as you say, but
one day, you may come to realize that it doesn't work that way. People
will do things that may not be in accordance with your way of thinking.

Get over it.
