3. Is the video input signal properly terminated? Set in Image settings – Video
Options menu.
4. The screen size may be too large. As screen size increases, magnification
increases, reducing brightness and clarity. See lens specifications in Section 5.
5. The source input signal may be of low quality. Try another source.
Colors in the display are inaccurate...
1. The color, tint, gamma, color space and/or color temperature settings may require
adjustment. Review all settings. See also Section 3 for descriptions and
instructions.
2. Check cable connections. Make sure Red is red, etc.
Turning White Boost ON appears to dim image...
1. For all new sources, perform Auto Setup (accessible in Main menu) and enable
Auto Input Levels (Input Levels) before applying White Boost. Note: Auto
Setup should automatically optimize your input levels for the most common
sources. Only trained technicians should adjust input levels, if further adjustment
is required.
The display is not rectangular...
1. Check leveling of the projector. If necessary, try relocating the projector or
screen so that the lens surface and screen are approximately parallel.
2. The adjuster mechanism may need tweaking in one of its axes.
3. The Vertical Stretch option may need adjustment. Also check pixel tracking.
4. Turn keystone to 50.0.
The display is "noisy"...
1. Display adjustment may be required. Adjust pixel tracking, phase and filter.
Noise is particularly common on YPbPr signals from a DVD player.
2. The video input may not be terminated. Make sure the video input is terminated
(75Ω). If it is the last connection in a loop-through chain, the video input should
be terminated at the last projector only.
3. The signal cables carrying the input signal may be of poor quality. Use only good
quality signal cables.
4. Switching between analog and digital sources (both connected to EM at the same
time) – disconnect the source that is not being used.
5. The distance between the input source device and the projector may be too great.
If the distance between the input source device and the projector is greater than
25 feet, signal amplification/conditioning may be required.
6. The input signal may be of poor quality.
7. If the source is a VCR or off-air broadcast, detail may be set too high. Keep near
4 for most sources. (Check defaults - may be different for other sources.)
The display suddenly went dim...
1. Lamp operation mode switched from Dual Lamp to Single Lamp – check Lamp
menu to confirm. Lamp may require replacement.
