Belkin KVM causes black screen

Well...after many years of popping into TH for info and sending others here for help , I'm now in need of some serious help myself.

I have a belkin 4 port KVM Model F1DS104U. It has been a fairly good little KVM for some time. I've been using it with an ADi E66 19" CRT for about 2 years. I also have an ADi PD-959 19" CRT w/ built-in USB hub. Both use VGA connectors.

Here's the problem: when I hook everything up and use the E66, all is well. If I remove the E66 and put in the PD-959, there is no display on the CRT. Its almost like the brightness is turned all the way dark....but its not. Now....to make things fun... If I take the PD-959 and plug it directly into each of the four PCs, the display comes up just fine. Plug it back into the KVM and darkness.

Belkin says its an incompatibility with my monitor. Well well well. What other monitors doesn't this KVM work with then??? They didn't have an answer.

I know there are a bunch of ground pins and a couple "not connected" pins. Did Belkin take a shortcut with their KVM that causes this problem????? I'd really like to solve this little mystery, but Belkin (after 3 emails and a phonecall) couldn't care less.

I'm going to try ADi next.

Does anyone have any insight????

I've always used this site for info. Its a wealth of knowledge that maybe I'll be able to contribute to.

Thanks,
Mike

I appreciate the info. I did a Google search, but I guess I didn't do one on the PD-959. Sometimes I'm just not all here.

Guess I'm going to have to investigate this one myself. I'm stuck since its the only monitor I have for the next couple months.

Well...there's more to it than just getting a new KVM. I have the curiousity that wants to understand why this is happening. In my gut I have this feeling that something is there that can be fixed. I'm a field tech and I love solving little mysteries like this. Ok..maybe I'm just sadistic.

I looked on Newegg. Nothing for me under $100. Besides...even $36 could be better used elsewhere.

I spent good money on this KVM and the more I talk with them (Belkin) the more angry I get. They really couldn't care less.

Guess I'll just have to keep looking for an answer.
