Corner Fit and 2D Keystone Adjustment Notice
The corner fit function is closely related to the 2D keystone function as both make 
adjustments to correct picture distortion. Therefore, when correcting picture distortion, 
both corner fit and 2D keystone functions should be used in conjunction to achieve the 
best picture shape.
To achieve the best picture shape:
•  When installing the projector, align the projector to the screen so they are as 
perpendicular to each other as possible in order to minimize picture distortion.
•  When making corner fit adjustments, if the desired effect cannot be achieved, adjust 
the 2D keystone value and try again.
•  When making 2D keystone adjustments, if the desired effect cannot be achieved, adjust 
the corner fit value and try again.

Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only 
display one full screen at a time. When starting up, the projector automatically searches for 
the available signals.
Be sure the Quick Auto Search function in the SOURCE menu is On if you want the 
projector to automatically search for the signals.
To select the source:
1. Press SOURCE on the projector or remote 
control. A source selection bar displays. 
2. Press / until your desired signal is selected and 
press MODE/ENTER.
Once detected, the selected source information will 
display at the corner of the screen for seconds. If 
there is multiple equipment connected to the 
projector, repeat steps 1-2 to search for another 
signal.
•  The brightness level of the projected image will change accordingly 
when you switch between different input signals. Data (graphic) 
PC presentations using mostly static images are generally 
brighter than Video using mostly moving images (movies).
•  The native display resolution of this projector is in a 4:3 
(MX882UST)/16:10 (MW883UST) aspect ratio. For best display 
picture results, you should select and use an input signal which 
outputs at this resolution. Any other resolutions will be scaled by 
the projector depending upon the “aspect ratio” setting, which 
may cause some image distortion or loss of picture clarity. See 
Selecting the aspect ratio on page 29 for details.
•  Firewall in the PC must be switched off to allow USB Display to work. 
						

							Operation 29
Changing Color Space

Selecting the aspect ratio
The “aspect ratio” is the ratio of the image width to the image height. Most analog TV and 
some computers are in 4:3 ratio, and digital TV and DVDs are usually in 16:9 ratio.
With the advent of digital signal processing, digital display devices like this projector can 
dynamically stretch and scale the image output to a different aspect than that of the image 
input signal.
To change the projected picture ratio (no matter what aspect the source is):
•  Using the remote control
1. Press ASPECT to show the current setting. 
						

							Operation 302. Press ASPECT repeatedly to select an aspect ratio to suit the format of the video 
signal and your display requirements.
•  Using the OSD menu
1.
Press MENU/EXIT and then press / until the DISPLAY menu is highlighted.
2. Press  to highlight Aspect Ratio.
3. Press  /  to select an aspect ratio to suit the format of the video signal and your 
display requirements.
