[. . . ] · Depending on the input signal, full-size display may not be possible in some cases. · Although the projector can display signals with resolution up to UXGA (600x200), 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. [. . . ] · Automatic adjustment may not function correctly with some input signals. · The image may not be displayed correctly when the input sync signal is a composite sync or a sync on G. Initial set signals Initial set signals The following signals are used for the initial settings. In such case, adjust the items V POSITION and H POSITION in IMAGE menu. Back porch (B) Data H.

Increasing the projector setting value (Increment command) () The PC sends the following increment code to the projector. Header+Commanddata(`04H'+`00H'+type(2bytes)+`00H'+`00H') (2) The projector increases the setting value on the above setting code. Decreasing the projector setting value (Decrement command) () The PC sends the following decrement code to the projector. Header+Commanddata(`05H'+`00H'+type(2bytes)+`00H'+`00H') (2) The projector decreases the setting value on the above setting code. 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 PC. In such a case, the command is not executed and the error code `15H'is sent back to the PC. When the projector cannot execute the received command, the error code `1CH'+ `xxxxH' is sent back to the PC. When the data length is greater than indicated by the data length code, the projector ignore the excess data code. [. . . ] When the projector cannot execute the received command, the error code `1CH'+ `xxxxH' is sent back to the PC. When the data length is greater than indicated by the data length code, the projector ignore the excess data code. Conversely when the data length is shorter than indicated by the data length code, an error code will be returned to the PC. NOTE · Operation cannot be guaranteed when the projector receives an undefined command or data. [. . . ]
