KVM switch + Windows 7 creates monitor switching nightmare

I have been having a similar problem. I have various XP/Vista computers plugged into my 4-port KVM, and I put Windows 7 on one of these. Now whenever I switch to it, my monitor simply says "No signal". Every other computer works fine.

I happen to be poor, and use whatever junk computers I can get my hands on. This KVM was another cost cutting measure, to not require multiple displays and keyboards. I bought a cheap computer, and it had the windows 7 free upgrade offer. I took advantage of it with much glee.

I now cannot use my main computer with my other 3.

I hope this issue can get resolved, because as a student, it is really interfering with my life.

I don't know if it's related, but my windows 7 box has started to reboot without warning when switching from my other machine. It started right after the "reliability" update was installed. Anyone else seeing that?

Besides changing the title, maybe we should spread the word and inform people from different channels by creating a website dedicated to this problem. Included in this site can be the current status of the problem, actions taken to resolve the problem and their results aswell.

I thought Microsoft Answers was the best place to start this thread at first, but now I see that even with 8,248 views and 180 replies, no one from Microsoft is even interacting with it. I am also worried about this thread being closed or deleted somehow, all people having this problem might lose all this information shared here. But we can also start a new thread with a more appropriate title in case of that.

Anyway, I suggest a website which doesn't belongs to Microsoft so that all these people on this thread can keep in contact even if something happens to this thread at Microsoft Answers. Though I don't have enough time to form that website, maybe someone volunteered could do that.

I'm hoping that MS is working on this - and that it will be in an upcoming patch or SP-1.

However - I see that there have been 8,046 views, and 173 (now 174) replies to this thread - yet only 52 people have taken the time to mark it as they need an answer.

PLEASE MARK THAT YOU NEED THIS ANSWERED.  The more votes that are put towards this - the better the chances that MS will do something about it.

I am also interested in verifying what pin for DVI needs to be removed.  I wouldn't mind trying it if it solves the problems...

This is a good idea Joseph. Unfortunately I also think the message title misleads people into thinking this is a problem isolated to the niche kvm market whereas these EDID auto resolution adjustments are effecting multiple display and even single display users as well.

Perhaps modrais (if he's still here?) can amend the title?

A new issue would be good, but I dont want to lose the momentum behind this thead either.

Sorry eris667

I was gona post saying that it worked cause it seemed to for a while but now its not again :( i removed the pin from the vga cable - - -  *http://nookkin.com/content/allowing-any-screen-resolution-on-vista.php*- - - it intermittently works for me which is strange, i know the kvm can support res of up to 2048x1536. I have had a look on atens website and they say to do this - - - http://support.aten.com/sr\_detail\_p.asp?SR\_Number=K081200085

• • • it doesnt always work. Im at a workplace and i got a g41 chipset but my mates g31 does it aswell. Works fine on my old xp pro machine. Just annoying as it is randomly does or doesnt work.

DELL optiplex 380 using G41 chipset onboard graphics - tried updating

Win 7 enterprise

Dell EH2210H LCD

Aten CS1734B USB/VGA KVM - -  that says - - Video DynaSync™ - stores the console monitor's EDID (Extended Display Identification Data) to optimize display resolution

Like i said xp pro works fine.
