The Optoma HD803 has its control panel laid out in a straight line, on the top, along the back edge. This means that the menu keys are not laid out in the traditional diamond shape, which is unfortunate. That said of course, you would normally be using the remote control regardless, so it's not a big deal. The buttons have very bright blue LEDs that can partially light your room up, but they turn themselves off automatically when the projector is showing content. When you power down, they flash while the Optoma HD803 projector is cooling down, and it's almost an impressive light show.
The Optoma HD803's control panel runs along the back of the top of the projector. On the far left is the power switch (once for on, twice for off). Moving to the right, next is the Menu button, followed by the up and down arrows, then the left and right, and finally, the Enter key. The left arrow doubles as the Source select button when the menus aren't in use, and the right arrow, doubles as the re-sync button, primarily for locking on to a PC analog source.
