Question about NEC VT470 Multimedia Projector

1 Answer

I am using a NEC data projector for the past 5 years. Recently I have problems in displaying a video(DVD)using directX/WindowsMediaPlayer or any other plugin. The video is displayed perfectly on the laptop; however on the projectered image, only the outer layer of the plug-in is visible and not the actual video- this area is black- with no picture. Please help.

Its a common problem of the video hardware in the laptop - it hasnt the ability to split the video "overlay" (often its decoded by something in the video chip, or at least a seperate bit of software and output seperate from the usual, slower windows & images data stream) off to the second screen & you just see the frame of the player.
if you set the external output to be the main/primary, or sometimes only active screen, it should work. you might also have a chance if you make it an extended desktop rather than a cloned one, then moving the player window entirely onto the projector's "screen"

    Addendum to this: If you can make the player START on the external display - or even launch it WITHOUT a video playing or loaded on the internal screen, and move it across to the external before loading or playing anything (make sure all parts are fully transferred, nothing remaining on the internal display), then it MIGHT then work. I do know Windows really hates moving active video windows between physical screens, and flat out refuses to "split" video between them in most cases, especially with mobile chipsets.

URGENT: How can I connect my tv to my NEC VT695 projector?


Do you want to duplicate the image going from the source to the projector on your TV? If so, then if your TV has a VGA port, just use the monitor Out on the projector. If your TV doesn't have a VGA port, you'll need an appropriate converter. (Avoid a VGA to component video or VGA to composite cable.) If you add a comment with more information on the inputs for the TV (or the model of the TV), then I will try to point you to the correct converter.

If you want to get your TV signal to the projector, you would need a set-top box (cable, satellite, digital tuner) as the source. Most TVs do not have a video output. You can connect a computer or DVD player to the projector.

The manual and quick guide for the VT695 are available from NEC here: http://www.nec-display.com/dl/en/pj_manual/vt695_491.html . The direct link to the English language version of the manual is http://www.support.nec-display.com/dl_service/data/manual/english/vt695_491_manual_e.pdf .

I hope this helps.

Como desarmar un mini split carrier


You tried three notebooks, but did they have the same video adapters? Try a notebook with a different video adapter. i would say your video adapter isn't good enough to put out a dual display. you might need to get a laptop with a better video card

There is a blue glow in the bottom left hand corner of the image


I have had this problem with projectors unfortunately can't quite remember the exact problem. It will get worse though as it is wear and tear. Its either a polarising lens or the lcd panel is burnt out. I have had them repaied in the past but could cost at least £300. You can buy very good spec NEC projectors for just over £200. That is new and including the lamp. I recently bought 7x NEC NP115. They are great value for money, 3000hor lamp life and new lamps are abought £120.

Hope that is helpful to you

Pink tint when usig the RGB component cable


Check the green signal lead - if one of the RGB leads doesn't make good contact, the picture will take on an odd tint that doesn't always look like it's missing one of those colours. For some reason, the green is always the most common one to fail.

No input detected on projector


it sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

Problem with NEC Multisync MT830


Check to see if the fan is running on the bottom of the unit. If it senses no rpm from the fan, if will shut down to protect the unit.
