A lot of pro turkers recommend using multiple monitors to increase your productivity. I have seen people using two, even 3 monitors in some cases. I personally use the second monitor to look for hits. I use two side by side windows, first one is a mturk window sorted by newest first and refreshing every 10 seconds, the second window is turkalert where I blocked all unwanted requesters and I use to catch any hits that I might have missed otherwise.
I am inviting all you guys who use multiple monitors for turking and share how use it to increase your productivity.
