Question: can you set up dual monitors with one vga port?
Answer: If it's a laptop with only a VGA output, you might want to consider getting a newer one, as it's probably pretty old. As others have stated, you can use a VGA splitter (which will give the same image on both monitors) or use a USB to HDMI, or USB to DP, or USB to DVI (or even to VGA) to get a second video output.
