External Display Delay

[dukebound85]

I have an external display I use. Every time I plug it in via mini-diplay port/dvi, I get a good 20seconds of a white noise looking screens but with all of the colors of the pixel

What causes this? Is there anyway to have my screen pop up right away and not have to wait for this? The internal screen on my mbp is fine, just the external needs some time to output the signal.

More info on the display, MBP model, etc might help people with opinions.
