Windows 7: KVM switch, Windows 7 & changing screen resolution

KVM switch, Windows 7 & changing screen resolution

Hi Everyone,

I am having an issue with screen resolution which is related to the use of a KVM switch - Wikipedia, the free encyclopedia with my Windows 7 computer.

When I boot into Windows 7 with the KVM switch set to my computer (e.g.: I watch the entire boot process from "white writing" to Windows loading) screen resolution remains at the setting that I chose (in my case 1280 x 1024).

However if I boot my Windows 7 computer and it is not active on my KVM (e.g.: I don't see the boot up) and then I later switch to the computer the resolution on my monitor is lower (1024 x 768).

This is an annoyance as all of my screen icons are moved around. Ideally I would like to be able to set Windows 7 to a screen resolution of 1280 x 768, and "lock it in" so that it loads with the desired screen resolution regardless of whether or not the Windows 7 computer is selected on my KVM.

If you have any advice it will be greatly appreciated.

Thanks

Davo

As far as I know there is no fix for this problem.
When you boot up a computer with a KVM switch that is not switched to on the KVM it does not know what monitor is attached and sets it to a default setting usually 1024x768.
Your KVM switch sets the resolution and not your PC.
The only way is to boot up one PC with the KVM switched to it then boot up the other one with the KVM switched to it (a real pain in the rear) that's why i did away with my KVM.

Kodi is correct. The PC will boot to the resolution of the PC it sees. You have to have the correct PC switched to while loading windows. Right up until the desktop starts to load. We all learned this the hard way

I have found a work around! :)

Hi Guys,

I have discovered a work around, it involves using a program called Carroll, http://www.softpedia.com/get/System/.../Carroll.shtml, to set the screen resolution. This program will restore the desired screen resolution on boot up. However it can only do so after the initial boot process, which typically occurs at a lower screen resolution. The result is a desktop at the right resolution but with icons in the wrong locations.

To overcome the movement of icons it is possible to use a program called Fences, Stardock.com - Your Edge In Software,which keeps icons in the same place regardless of the screen resolution. Fences is also very handy when working with a Virtual Desktop (e.g.: Windows XP in Windows 7) environment for keeping icons in the right place when switching into and out of full screen mode.

Cheers

I wrote a small application to fix that annoyance

The app is running in the background and listening for any "changed resolution" event.
When this event is triggerd by the system, The app will restore your resolution immediately.
You need to define your resolution in the config.cfg file (just open in notepad).
Cheers
