The playing angle is more important to me than the reading angle. I could never play a board that was not the correct, comfortable height and angle. As for reading ... I only glance at the display now and then anyway, so it's a second issue for me. If your eyes are looking down, the crowd can't see your smily face !

My "On Stage Stand" has height adjustments on all four legs. Could solve the screen viewing problem.

What could fix the viewing problem is that Yamaha either installs a manual tilt screen...or fixed angle with brightness adjustment after the designers actually test it at all playing positions sitting & standing. Then they can stat working on another Usable NEW quality Vocalizer too.
