Thanks so much for your help. I tried "nvidia-setting" to detect the display, it works and can detect the connected display.
But there is another issue about the resolution: My laptop (DELL D630) is 1280x800, the connected LCD monitor is 1024x768, thus only parts of laptop screen are shown on the LCD monitor. I wonder if there is a way to change the resolution of the connected LCD monitor or projector? I tried to use "xrandr --output VGA --mode 1280x1024", the xrandr seems doesn't work on my laptop because nothing happens after I ever execute the "xrandr" command to switch my screen.
