KVM switch + Windows 7 creates monitor switching nightmare

I have a problem with Windows 7 and my KVM switch (Iogear model# gcs1764) which is makes switching via KVM an absolute nightmare.  The iogear KVM does not use drivers nor are any available on their website.

Here's what happens:

I switch from Win 7 (2 monitors) to XP (1 monitor) via KVM.  When I switch back to Win 7 (2 monitors) sometimes Win 7 will throw my desktop to the 2nd monitor (1st monitor goes blank) and opening up display settings only shows the 2nd monitor as existing.  It's as if the 1st monitor is now unplugged which it isn't.  At this point I have to go into display settings, click Detect, and then it re-detects my 1st monitor and "extends" my desktop back out over 2 monitors.  All windows have now been thrown to my 1st monitor and i have to rearrange all my work back across 2 monitors.  This is why KVM switching in Win 7 makes my work life a living nightmare.  This isn't all of it either...

When everything gets thrown to my first monitor, it takes any windows that were maximized and resizes them to about 1/4 my screen size.  Due to compatibility issues between Win 7 and SQL Server Management Studio, Management Studio has a redraw bug that doesn't "re-size" the query window correctly.  So even though I maximize the app, when I start typing in the query window my text disappears about 1/4 the way across the whole window.  The only way to fix this is to save all my work, close the app, and then re-open the app with all my work.  So basically every time I switch computers there's about a 1/5 chance I have rinse and repeat everything I just typed above.  Fun times.

So are there any future fixes planned for this?  I have tried everything and nothing fixes this problem.  I have all the latest Nvidia drivers (my card: Nvidia GTS 250).

    I'm sorry Afzal but these answers are not very helpful at all.  I think most people on this forum know where to change their monitor resolution.  The point is we don't want to buy expensive new hardware to use Windows 7 or have to go through a bunch of hoops every time we use our KVM switch.

    Hopefully the requests to fix this will encourage Microsoft to release a fix within Windows 7 or allow us to disable monitor polling in Windows 7.  Other OS's don't have this problem so there's no reason that Windows 7 should.  Until then, I encourage anyone with this problem to click the "I need an answer too" button and post your issue here in the hopes that Microsoft will hear us.

    OK just quickly so I don't come across as a total Microsoft hater.

    Windows 7 is by far superior to Vista and is a landmark release along the lines of XP.  Apart from this one minor issue I am more than impressed by it, and enjoy using it.

    However - it's the little day-to-day things like this that end up leaving a real bad taste in the mouth and can really spoil everything, so I'd encourage Microsoft (and their driver partners as necessary) to fix issues like this so we're not all left hanging.

    Afzal - this response is much less than helpful and is a regurgitation of rubbish I have seen elsewhere.

    Apologies but if your only suggestion is 'buy new hardware' then I have an alternative suggestion - use OS X.

    Again I'd like to re-iterate that this problem _did not occur under Vista_ with _exactly_ the same hardware.

    @Truth Telling Fool - I found another super crummy but slightly less inconvenient workaround as well.  Minimise all windows to desktop (Windows-D) prior to switching on the KVM.  When you return to Windows 7 simply hit Windows-D to restore all windows (size and location) as they were before you dared to try and use your KVM.

    How great is Windows 7.  How much better is Microsoft Support.  Count them on one finger.

    Hi ,

    Thank you for visiting Microsoft Answers.

    The resolution you can use depends on the resolutions your monitor supports. CRT monitors generally display a resolution of 800 × 600 or 1024 × 768 pixels and can work well at different resolutions. LCD monitors, also called flat-panel displays, and laptop screens often support higher resolutions and work best at a specific resolution.

    The larger the monitor, usually the higher the resolution it supports. Whether you can increase your screen resolution depends on the size and capability of your monitor and the type of video card you have.

    Refer this link for more information on how to change the screen resolution in Windows 7:

    Additional information about Display Guidelines for KVM Switches in Windows 7:

    To optimize a better user experience with display devices that are connected to a KVM switch, this document discusses all applicable KVM scenarios, tests, and specifications. This information specifies how a KVM switch and the Windows 7 operating system can work together to enhance the user experience with display devices.

    Please download the document and read it for better understanding.

    All, I found a workaroundfor my situation.  It is a crummy workaround, but it works for me.  When I switch back to Windows 7 I reach back and pull the power cord on my KVM.  When I plug it back in Windows 7 picks up the change and switches the display resolution back to my full resolution.
