Changing Default Monitor when none is connected?

by eatlas / February 14, 2008 10:04 AM PST

I use VPN to talk to a computer running Windows XP. Remote display is fine if the source computer is booted with monitor connected. If the computer is booted with monitor disconnected (this needs to be the default case), the remote display shows a 640 x 480 resolution that apparently is related to some default setting in WinXP. I need to get back to the 1280 x 1024 or similar resolution when the computer is booted without monitor. Can this be done??? Thanks.

Win XP defaults to a generic setting

for the video setting until the drivers for the monitor are loaded. You do not mention the flavor of XP the remote system is running. If you booted the remote with a monitor and then shut the monitor off, I would think it would still hold the setting. Windows OS for a server would be a better choice for the system acting as a server. Just what are the circumstances on this? More info please.

Monitor display resolution problems
by eatlas / February 14, 2008 9:25 PM PST

You are correct that when the computer acting as server is booted with a monitor attached, and then it is removed, the resolution is unaffected. The remote computer viewer connects to a screen with good resolution. However, the situation is often the case that the server computer needs to be booted without a monitor. In this case, I can only view the generic 640 x 480 setting and cannot change it remotely. Display properties are locked. All I see in device settings are "Default" and "Plug and Play" monitor, but am not sure about messing with these settings. The computer acting as server runs LabView to control an instrument aboard a research aircraft. The VNC connection is to another computer onboard the aircraft. Both server and remote computer run WinXP Pro, and run TightVNC for communication. Thanks!
