Information processing apparatus including rotatable display device, and image forming apparatus

An information processing apparatus comprising:

• a display device that has a rectangular shape and has long sides and short sides;
• a rotation mechanism that allows the display device to rotate between a landscape orientation in which the long sides are a top and a bottom and a portrait orientation in which the short sides are a top and a bottom;
• a detection sensor that detects whether the display device is in a landscape-oriented state or a portrait oriented state;
• and
• a control device that includes a processor and causes the processor to execute a control program to function as a controller that causes the display device to perform display according to a posture in the landscape-oriented state or the portrait oriented state of the display device based on a detection result obtained by the detection sensor, wherein
• when the controller determines that the posture of the display device has switched between the landscape-oriented state and the portrait oriented state at a predetermined frequency or more based on the detection result obtained by the detection sensor, the controller causes the display device to display a message indicating occurrence of a problem related to a rotational operation of the display device.
