I am running a theatrical project with 6 Windows XP laptops, all 1440 x 900 resolution, connected to 6 Canon WX450ST projectors (also 1440 x 900). Four of these projectors are working great, but the other two are not reporting a 1440x900 signal, but instead are reporting an input signal of 960x1028 (shown in the projector's settings menu). I have checked the resolution settings on the two corresponding laptops, and they are correct. When I go to the NVidia control panel on the laptops, these two laptops are not recognizing the Canon projectors, but instead just a generic analog display of 1028x768. (The other four projectors actually report the Canon projectors, along with the correct model number, in the NVidia control panel.) I've tried everything I can think of - how do I get Windows XP (or the NVidia graphics card) to properly recognize the 1440x900 resolution of the Canon projectors?
