Correcting Trapezoidal Distortion

Note
•The Keystone Correction can be adjusted up to an angle of approximately ±13 degrees and the screen can also be set up to an angle of approximately ±13 degrees (when the resize mode is set to “NORMAL” (see page 32)).

Info
•While adjusting the image using Keystone Correction, straight lines and the edges of the image may appear jagged.
Note
•Automatic Keystone Correction may not work well in some cases, such as when the screen is leaning, temperature is extremely high or low, or zoom is at maximum or mini- mum. In these cases, fine adjust the Keystone Correction following steps 1 to 3.
•You can select “On” or “Off” for the Auto Keystone Correc- tion mode. (See page 41.)
