Auto Adjust:
When “Auto Adjust” is set to “On”, the projector automatically determines the best resolution for the current RGB input signal to project an image using NEC’s Advanced AccuBlend Intelli- gent Pixel Blending Technology.
The image can be automatically adjusted for geometry and sta- bility; “Horizontal Position”, “Vertical Position” and “Pixel Ad- just.”
On:
Off:
Horizontal/Vertical Position (when Auto Adjust is off): Adjusts the image location from left to right.
This adjustment is made automatically when the Auto Adjust is turned on.
Pixel Adjust (when Auto Adjust is off):
Displays the Clock and Phase adjustments.
Clock: Use this item with the “Auto Adjust on” to fine tune the computer image or to remove any vertical banding that might appear. This function adjusts the clock frequen- cies that eliminate the horizontal banding in the image. Press the ◀ and ▶ buttons until the banding disappears. This adjustment may be necessary when you connect your computer for the first time. This adjustment is made au- tomatically when the Auto Adjust is turned on.
Phase: Use this item to adjust the clock phase or to reduce video noise, dot interference or cross talk. (This is evident when part of your image appears to be shimmering.) Use the
◀and ▶ buttons to adjust the image.
Use “Phase” only after the “Clock” is complete.
This adjustment is made automatically when the Auto Adjust is turned on.
Resolution (when Auto Adjust is off):
This allows you to activate or deactivate the Advanced AccuBlend feature.
Auto: Turns on the Advanced AccuBlend feature. The projec- tor automatically reduces or enlarges the current image to fit the full screen.
Native: Turns off the Advanced AccuBlend feature. The projec- tor displays the current image in its true resolution.
NOTE: While you are displaying an image with higher resolu- tion than the projector's native resolution, even when you are in the Native mode, the image is displayed full screen using the Advanced AccuBlend feature.
Color Temperature
This feature adjusts the color temperature using the slide bar.
Move the slide bar to the right to increase the color temperature for a bluish image; to the left to decrease it for a reddish image.

Keystone
This feature corrects the keystone (trapezoidal) distortion to make the top of the screen longer or shorter to be the same as the bottom. Use the ◀ or ▶ buttons on the slide bar to correct the keystone (trapezoidal) distortion.
NOTE: The maximum keystone angle that can be corrected is 15 degrees upward and downward with the projector placed horizon- tally. However, a picture will be blurred if you correct the keystone angle beyond +12 degrees or more for SXGA signal on MT840.
