The image from my computer appears stretched when it's projected. What should I do?
Try the following solutions:
Press the Aspect button on the remote control to select a different image aspect ratio.
Check your computer display settings to disable dual display and set the resolution within the projector's limits. (See your computer manual for details.)
Set the projector's Resolution setting to Auto so the projector automatically identifies the resolution of the input signal. If necessary, select Wide (for widescreen images) or Normal (for 4:3 ratio images).
Check the resolution assigned to your presentation files to see if they are created for a different resolution than you are projecting in. (See your software help for details.)
