We cannot alter the red green blue numbers in color setting. currently we are using the projector for a home theater and the projector does not come close to true color. is there a way to unlock the color settings? the cursor only allows you to exit that screen... we cannot change the rgb numbers which are all set at 50. we tried calling dell tech support but the rep (in india) was not able to help. thanks.

If you mean the red light is displaying offset from the blue and green then the red LCD panel inside the projector needs to be physically adjusted. If you take the projector apart you'll notice that the light source is split into red, green and blue light by passing through an optical splitter. Each color then passes through it's own LCD panel. Next, each color is joined back together by another light splitter to be projected to your screen. The red LCD panel is misaligned.
If you are using a component video cable (Red, Green, Blue) you may simply be missing the Red cable. It may not be fully plugged in.
You can verify that this is the case by:
1. Unplugging all video cables
2. Plug in the green cable, you should see a black and white image.
3. Plug in the blue cable, you should see some colours coming through.
4. Plug in the red cable, you should see all colours properly.
If not, unplug the blue and red cables and plug the blue cable into the red port. The colours will look incorrect, skin tones will be blue.
If the colour comes through the problem is the cable.
If the colour does not come through, the problem may be the projector.
You should check the projector's settings to make sure you haven't accidentally altered the colors. Most computers allow for color distortion to be implemented on your display devices.
Go to Control panel, select personalization, and then click on Color Management. A number of profiles will emerge, and you will have to go through to make sure your color settings are correct. You should also go to your driver suite, which is provided by whomever manufactures your graphics card (ATI, Nvidia, or Intel), and check the color settings there, as they may have taken over the color control on your computer.
Using the on screen menu, check the hue or wall color settings.
Varies the color level from +/- green to +/-blue. The red level is used as reference. This adjustment is only valid for
Video, Component and TV standard inputs (not valid for RGB and DVI digital).
Using the Wall Color Correction [Wall Color]
This function allows for quick adaptive color correction in applications where the screen material is not white.
The following nine options are available.
• OFF • Blackboard
• Blackboard (Gray) • Light yellow
• Light green • Light blue
• Sky blue • Light rose
Have you tried using the video inputs, Is it able to show red then ?
If not & you have reset the factory settings the prisim or mirror's may have gotten out of alignment in shipping, Or it may have a bad lcd panel or the red lcd may have a bad connection or driver circuit.
In short If the reds show as red, The greens show as green & Blue shows as blue. I would say thats as good as it can project. It's hard to judge color without seeing it for ones self but usually DLP projectors that use a colorwheel do not have perfect color.
