It may not work consistently in landscape, but in general, if you look at an LCD with polarized glasses and can't see anything, try rotating the display (or your head) 90 degrees. Or just take the glasses off. This works because of the way LCDs function. An LCD actually uses polarization to turn pixels on and off, so introducing polarized optics at an angle perpendicular to the orientation of the LCD polarization means you see nothing.
