Vertical/horizontal keystone setting
Format
VKS=<Vertical keystone distortion value:Number>
HKS=<Horizontal keystone distortion value:Number>
Parameter
<Vertical keystone distortion value:Number>
<Horizontal keystone distortion value:Number>
The RANGE command can be used to obtain the parameter range that can be set at that time.
For details, refer to the RANGE command.
Response
"i:OK" is returned if the parameter was set properly.
For details on other responses, refer to the "Error List".
Description
This sets the vertical and horizontal keystones.
(1) For models other than SX7 Mark II: It can be executed when the projector is in both the remote mode and
power-on status at the same time.
For SX7 Mark II: It can be executed whenever the projector is in the power-on status.
(2) A “busy” response is given while the zoom or focus lens is being driven.
(Refer to the ZCONTDRV command and FCONTDRV command.)
(3) This command is identical to pressing the “KEYSTONE” button on the remote control or front panel.
(4) The settable keystone range varies depending on the input signal, screen size, number of horizontal and
vertical dots, and other factors.
(5) Changing the vertical keystone value modifies the setting range of the horizontal keystone value, and
changing the horizontal keystone value modifies the setting range of the vertical keystone value.
(6) Use the “RANGE” command to obtain the range of settable values immediately before setting the
vertical value and horizontal value.
(7) The keystone setting can be set when screen aspect is set to other than “16:9_DIS”.
When screen aspect is “16:9_DIS”, "e:1008 INVALID_SCREEN_ASPECT" is returned.
(8) The GET command can be used to retrieve the current vertical/horizontal keystone value.
For details, refer to the GET command.
Example
Setting
> VKS=-23 This sets the vertical keystone to –23.
< i:OK
> HKS=10 This sets the vertical keystone to 10.
< i:OK
Reference
> GET VKS or ?VKS This retrieves the vertical keystone.
< g:VKS=-23
> GET HKS or ?HKS This retrieves the horizontal keystone.
< g:HKS=-23
Obtain settable parameter range (Min, Max)
> RANGE HKS
< r:HKS=N, -30, 30 Any value from -30 to 30 can be set for the horizontal keystone.
