It's me again.
Look for a CRT TV or arcade monitor. It is the correct shape for an arcade cabinet and it has superb viewing angles. It also has the added bonus of displaying the games the way they were meant to be displayed. Oh, and I will jump off the top of my warehouse onto the pavement headfirst if you use an LCD.
It is a win, win, win situation. Of course if you choose the LCD and I jump, then I can't bother you anymore. So I guess that would also be a win.
