The picture directly below is of my main trading machine display.  I have 4 -23″ monitors.  Each of the windows is labeled.  This is by no means an ideal setup, I think it is quirky but it works for me.  I have another computer where I have stocktwits desktop, our chat and another browser window.  I also have a TV in the office which if it is on CNBC it is usually muted.  There is also a laptop which I rarely turn on, but use for travel.

For those who might be wondering, the software is REALTICK

Below are the specs for the computer which drives the screens above, it is about one and 1/2 years old.  The link to where I purchased it can be seen at the top of the picture.   There are probably better machines available for less money, I am not an expert in hardware.
