Question about Dell Office Equipment & Supplies

1 Answer

Using a Dell projector, is there a way to get it to project white without any inputs, versus the standard blank blue screen? It goes white when searching for inputs, but switches back within seconds when no input detected. I'm trying to use this white light for a non traditional application at work.

Since you did not provide the make and model, you will have to pull out the manual and check the settings. It may provide you with a setting change for the background color. Perhaps you can connect it to a computer, open an new blank document and project the blank image to get your white light.

-toggle the laptop display using the FN keys and F5 I believe. -lower laptop resolution to 800 x 600 -look in laptop display properties for lcd or external display settings, see if it (external crt) has to be enabled on the laptop first.

Hi mrus821

If the signal won't go through you will have to either have your Mainboard Repaired or Replaced.

This is unfortunatelly a common Mainbaord problem , and the above is the only way to get it fixed.

SOURCE: Infocus X1 picture freezes and dissapears and then comes on again

your display settings may be off, so change settings to factory reset and you may have to drop the resolution on your computer. you may also have a bad cable, so try a different cable.

green is ok.

red flashing in sequence:

3 times- lamp failure. replace lamp.
4 times- fans not working. remove obstruction or replace fan.
5 times- temp too high. clean thoroughly.
solid red- undiagnosed error by projector. possible power supply or ballast.

also make sure the lamp door switch is working.

Is there any way that I can connect my new WONDERWALL projector to my laptop computer


The wonderwall does NOT have the proper inputs for use with a computer for good reason.

A wonderwall projector is NOT a projector that is good enough to be used for movies or games and it would be embarrassing to make a presentation on one. It has WAY less resolution than even old fashioned standard definition TV. Standard def Tv is 720x 480 pixels at 30 cycles. A wonderwall is 480x 240 pixels which is appx. the resolution of a screen on your phone. That's 345,600 for STANDARD def versus only 115,200 pixels for a wonderwall. When you blow that up to 3 feet wide, it'll look pretty mediocre. We have one just like it and we use it to project VHS onto our garage during Halloween and Christmas.

It IS perfect for fun and might be ok to watch old VHS tapes but watching a dvd on one is horrible.

Your 1440 has VGA outputs. A wonderwall has AV (red, white yellow) inputs. You can buy a vga to AV adapter for less than 10 dollars almost anywhere. You don't even need to go to a specialty electronics store.

I have a VT465 and the projection back ground is yellow and I can't get it to be white


If you are talking about the actual image that is coming from a laptop being yellow instead of white, then this is caused usually by a bad signal cable running between the computer and the projector.
To be more specific: All colours in a projector get made up in some way between red, green and blue. White is all of these colours at maximum, yellow is made by red and green at maximum but no blue. If your image is Yellow when it should be white, then the blue signal information is not reaching the projector. This can also happen within the projector or computer itself but is less likely. If your using a VGA cable (15 pin cable) then blue is run through pins 3 & 7 (positive and negative respectively), see if your cable is either missing these pins on either end or if they are bent, although it's more than likely within the cable itself. You can test this theory easily by trying to put something blue on screen, if the blue signal isn't getting through then it'll appear black.
If changing the cable doesn't solve the problem try testing the computer by trying to use a different one, and test the projector by plugging in a monitor or another projector.

If you are getting a yellow screen without sending signal and just trying to get the "no signal" or "no input" screen white, then this won't be the case.

I'm noticed white spots on the screen and from the past two days its getting worse. kindly suggest me and give me step to step cleaning process if i can do it myself.


check if the white spots are well defined square pixels on the screen. If they are then you may have pixel failure.

  • After turning on the projector, press "+" and "-" buttons on the control panel simultaneously and release the buttons when screen goes blank.
  • Press "+" and "-" buttons again to exit the diagnostic mode.
  • 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.

  • If you believe it's dirt then disconnect from the power and undo the screws underneath the unit. lift the cover over the front of the machine and carefully remove the pcb to get at the optics. don't touch and glass bits with your bare fingers. clean the optics bits as necessary with a camera dust blower bellows. best of luck.

    VT45 Projector: Blue pixels throughout screen


    If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

    So, the problem is in the cable - solution is replace cable.
