Over VGA (using an adaptor on the GPU's DVI port), it works well. But when I switch over to the monitor's DVI port (on the same GPU DVI port as above), the monitor says 'Cannot display this video mode'. What gives?

Additionally, I have another 1280x1024 monitor running well at 1440x1152 over DVI-I. When I use the DVI-D port, it gives an permanent 'input signal out of range' message, while displaying the image just fine behind it. Any ideas why?

LCD monitors are only designed to display the native resolution. Anything beyond that is up to the scaler and firmware in the monitor. Monitors will usually accept lower resolutions, but many will not accept higher resolutions. The results can vary depending on the model and even different ports on the same monitor.
