Dell Projector 4100MP - Manual (Page 34)

l If your graphic card output signal is "Sync on Green", and you would like to display VGA at 60Hz signal, please go into
"OSD--> Management --> Signal Type" and select "RGB".
l Run "Self-diagnostic test" (see " Self-diagnostic for video ") for preliminary diagnostic on image color problem. Ensure that
the colors of the test pattern are correct.
Image is out of focus
l Adjust the focus ring on the projector lens.
l Ensure that the projection screen is within the required distance from the projector (3.9ft [1.2m] to 39.4ft [12m]).
The image is stretched when displaying 16:9 DVD
The projector automatically detects 16:9 DVD and adjusts the aspect ratio to full screen with a 4:3 (letter-box) default setting.
If the image is still stretched, adjust the aspect ratio as follows:
l If you are playing a 16:9 DVD, select 4:3 aspect ratio type on your DVD player if capable.
l If you cannot select 4:3 aspect ratio type on your DVD player, select 4:3 aspect ratio in the "All Images" menu within the
OSD function.
Image is reversed
l Select Management from the OSD and adjust the projection mode.
Lamp is burned out or makes a popping sound
l When the lamp reaches its end of life, it may burn out and may make a loud popping sound. If this occurs, the projector will
not turn back on, and will display "Lamp Failure" in the LCD display until the lamp is replaced. To replace the lamp, see
"
Changing the Lamp ".
Self-diagnostic for video
l Dell 4100MP Projector provides self-diagnostic test of the projector video display (for Video, S-video, and Component-i). Use
this advanced feature for preliminary self-diagnostic on your projector when encountering the display problem for video.
l After turning on the projector, press "+" and "-" buttons on the control panel simultaneously and release the buttons when
screen goes blank.
l Press "+" and "-" buttons again to exit the diagnostic mode.
l While in Self-diagnostic mode, the screen will run a seven-color-cycle test as following: "Red--> Green--> Blue--> White-->
Watchet Blue--> Dark Green--> Yellow." Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.
The remote control is not operating smoothly or operating in very limited range
When the remote projector control is not smooth or operating in very limited range, please follow below procedures for
troubleshooting.
1. Battery low? Check if the laser beam transmitted from the remote is too dim. If it is, replace it with 2 new AA batteries.
2. If the batteries are not low, the projector may be operating in very "noisy" RF environment with the interference from other wireless
devices. Use "
RF Learning " to solve the interference problem.
