[. . . ] · Although the projector can display signals with resolution up to UXGA (1600x1200), the signal will be converted to the projector's panel resolution before being displayed. The best display performance will be achieved if the resolutions of the input signal and projector panel are identical. · Automatically adjustment may not function correctly with some input signals. [. . . ] The signal timing of some computer models may be different. In such case, adjust the items V POSITION and H POSITION in the IMAGE menu. Back porch (B) Data H.

(2) The projector in creases the setting value on the above setting code. (3) The projector returns the response code `06H' to the computer. Decreasing the projector setting value (Decrement command) (1) The computer sends the decrement code Header + Command data (`05H'+ `00H'+ type (2 bytes) +`00H' + `00H') to the projector. (2) The projector decreases the setting value on the above setting code. (3) The projector returns the response code `06H' to the computer. When the projector cannot understand the received command When the projector cannot understand the received command, the error code `15H' is sent back to the computer. Sometimes the projector cannot properly receive the command. In such a case, the command is not executed and the error code `15H' is sent back to the computer. If this error code is returned, send the same command again. [. . . ] If this error code is returned, send the same command again. When the projector cannot execute the received command. When the projector cannot execute the received command, the error code `1cH' + `xxxxH' is sent back to the computer. [. . . ]
