Question about Optoma EP719 XGA DLP PROJECTOR 2000L 2500:1 CONT DVI-D WITH HDCP Multimedia Projector

Cannot get the projector to pick up signal from the computer

This projector was purchased for an association to use twice a year. It has less than 100 hours of use. Sometimes, we have a very difficult time getting this projector to pick up the signal and sometimes we do not.
As of right now, I'm trying to hook this projector to a new Dell Inspiron 1720. I follow the directions by first turning the projector on, then turn the computer on and it will pick it up, but it is not picking up the signal and it says, no signal. I've tried using the USB cable and I've tried using the VGA Cable.
I've tried pushing buttons on the projector to try to get it to run through the source settings again and I cannot get it to do anything!
So, I put the User disk in my computer to go through the manual. This computer reads Adobe 8, it would not read it. It wants Adobe 6. I put it in my other computer that has XP and Abobe Reader 7, still won't read it. I put it in an old computer with windows 98, Reader unknown and I cannot get it to work on there either.
I thought with these projectors, you just plug them in and they should automatically pick the signal up. I've had friends help when we've had problems and they've pushed F? something keys and eventually got it to read. I do not know what those keys are.
I'm very frustrated with this projector and wish I could get a manual to read to figure out the kinks every time we want to use it. Most of all, I have 1 week to get these 2 machines talking to each other.
Could it be a cable?
Any help would sure be appreciated.
Carla

PS I should have known. I would have problems with this question too. The projector is an Optoma EP745, but I had to enter another to get it to go through. It is also a XGA, 2500L projector that is discontinued

You need to press Fn+F8 repeatedly until you highlight "Both Display and Projector". See this: http://support.dell.com/support/edocs/systems/ins1720/en/om_en/html/keyboard.htm#wp1056315 in the owners manual.

The Fn key is between the left ctrl key and the windows logo key. The F8 is at the top of the keyboard and will have the words "CRT/LCD" on it in grey.

I don't beleive the projector is at fault here.

BTW you need the VGA cable to get a picture and the usb cable to be able to move the mouse and keyboard with the projector's remote control.

Yep projectors are just dummy devices but still you have to select the source setting and the type of cable when you connect it to a computer specially laptops, there is a setting on the menu in which you set source to AUTO/or computer on some. For the keys to press on the laptop, press the FN key and hold it down then look for F5 or F4 then press on it it will depend on the brand of laptop but on the F# keys just select the one that has the LCD icon or a monitor icon. Whats your email add so that i can send you lists of these keys to press on different laptop brands

Hey, the solution is very simple the laptop is not set to use the vga output. All you need to do is to turn the vga output on.

Yeah its the FN (function key) and f1-f12 .. On my laptop its F7. so FN + f7 should do it.

Il post more detailed instructions if needed.

  • Ekse Apr 10, 2008

    check what the buttons f1-f12 read. one of them should read LCD/VGA thats the one.

  • Ekse Apr 10, 2008

How to connect optoma pk100 projector to a computer (15 pin). I got an adapter (15 pin to AV) but it doesn't work.


Let me start off by saying that the adapter that you picked up only works on select video cards. If your computer has an s-video connection, plug your video into that (use an s-video to composite adapter if you need to). If your computer does not have an s-video connection, your best bet is to pick up a VGA converter box. Search " PC to AV TV Signal " to find one.

Hi 1ivans

I would suggest that you should firstly try another DVI cable.

If this doesn't work , then the comms board will most probably need replacement.

LCD projector no signal message


Usually means that the computer is not sending a signal out the the projector via the monitor cable. Most Windows based laptop computers allow you to connect to a second monitor by pressing the Fn + F7 or F8 key, once to allow just the projector, twice to allow both the projector and laptop screen and three times back to only the laptop.

MITSUBISHI HC 100 PROJECTOR


Hi there

First try to bypass the box and put signal directly into the Projector from the source - i.e. DVD Player

If the signal still doesn't pick up , try using a different cable.

If the problem is solved , then your Converter Box is faulty.

If the problem still occurs then you might have a faulty Mainboard - as all the inputs on this Projector is situated directly on the Mainboard.

Hope this will help you !
