I'm reading this thread while playing micros... But I usually just listen to music or observe other players live. Depends on how serious the game I'm playing is to be honest.
Usually I just like listening to music. Sometimes I watch poker streamers while playing. But, i found that when I watch something while playing i find it distracting and I make more mistakes. So usually I just listen to music and play so that I can focus entirely on my game.
When I'm playing just one table specially turbo mtts, I like to watch a movie so I can play just with good hands, when i'm not doing anyhing I can't wait and so I play with 72o. ¬¬
I tend to watch the forex/commodities or the stock markets on a side screen if its during trading hours( habit my father got me into) and quiet music. In person I usually don't do anything but focus on whats going on.
i have 3 computer monters set up a 51 inch and two 20 inch so i play games and watch movies some times and on the other monters helps past long hours of cards playing
