long and technical article, but basically it finds that the vblank signals in the analog and digital outputs are not synchronized on most graphics cards; hence measuring the input lag difference between a crt monitor and an lcd monitor with the lcd monitor connected to a digital output isn't a great idea.
what I'm curious about is whether this is significant input lag in the digital-to-analog process in the graphics card. If there is, then CRT monitors may have more input lag overall than some lcd monitors.
