Hi,
I am running 2 x Server 2003 PCs and 4 x XP PCs all into a Daxten KVM. The resolution I need is 1440 x 900.
On power up the XP PCs are all set to 1440x 900 but only if one of the servers is selected at the KVM does it come up as 1440x900, the other is set to default monitor at 1280x768 and under Windows properties there is no option to select 1440x900. The only solution is to select the second server on the KVM and reboot the PC. This is not acceptable once we ship the system to our customers.
I have changed to an Avocent KVM with identical results. I also have a Belkin but I expect it will be the same.
Does anybody know a way of forcing the 2003 default monitor setting to 1440x900 or have another solution to this problem?Thanks

Is the screen resolution of 1440 x 900 supported by the graphics adapter of that server, you've got this problem?
Please check and let me know.

exactly right. You can't force a card to support a res setting it can't support.
I have a pretty high end video card and 1440x900 is NOT supported.
You should also review the kvm specs as some also have limits to supported resolutions.

Hi,
Yes I believe so but I will check. As I say if either PC is selected the PC has no problem in detecting it through the KVM and assigning it as "Plug & Play Monitor on ATI Radeon HD2400 Series". The other one (server 1 or server 2 whichever is not selected, detects a default coming from the KVM and the PC assigns it as "Default Monitor on ATI Radeon HD2400 Series".
If a PC is powered up with no monitor attached and then later a monitor is attached the screen stays blank. So the KVM must be supplying the default setting to the PC.
The same condition does not appear on the XP machines possibly because XP does not pick up the monitor configuration from the monitor itself.I'll go check the graphics settings.
cheers

Hi Wanderer,
Why does it work OK when the monitor is plugged direct into the Server PC or when it is the selected KVM channel on power up?
cheers

So the graphic card obviously supports the resolution.
If possible, switch of the DDC, which automatically checks the resolutions of the connected monitor at startup.
This should help.

The problem is the kvm issues a faux monitor signal to the system.
By some new lcd monitors for each system. The only other choice would b to re-flash KVM to send faux in that range if you can the kvm.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

I'm sure that the issue was caused by the KVM switches not supporting "active DDC" to those connected systems (connected to the KVM switch)when the user not select to it.
A full active DDC KVM switch will provide/remember the DDC setting even the connected systems are not selected/used.
