I'm trying to hook up my laptop (Toshiba A105-S4384) up to my desktop monitor. It is hooked up through a KVM switch (some IOGear model, the video is standard D-Sub/VGA).

The native resolution of my laptop is 1280x800 on a Intel 945GM chipset.

My monitor (Acer AL1916W) has a native resolution of 1440x900 which my laptop should clearly handle.

When I plugged in the monitor, the resolution did not go to the monitor's native resolution and also recognized the monitor as a generic non-PnP monitor.

Anyone have any suggestions on how to get the laptop to run at the monitor's native resolution?

You've tried to change the display resolution on the laptop?

Some KVM switches limit the resolution. The documentation on "the some IOGear model" should say.

A lot of laptops come with a VGA external port for hooking up an external monitor. since you have a KVM switch connected to the laptop is there a reason you just do not hook up the monitor directly bypassing the KVM and probably eliminating the resolution situation?

@hamluis: Yes, I tried changing the resolution from the laptop. The closest resolution was 1400x1200 or something around that.

@ThunderZ: The KVM I have can go up to 1920x1080. Obviously the quality diminishes since it's running from Analog VGA. I can't hook it up directly because I have one other computer that is connected and cannot take it down when I need to use the laptop. My desktop (though a different computer) runs just fine at the default resolution of the monitor.

I tried installing that driver, but it would not install. It said it wasn't necessary.

I did notice a topic on the official Intel forums regarding this same exact problem Here, so it may be a problem with the specific laptop.

Who knows.
