SOURCE: No live picture on Benq digital projector

seems to me like your acer laptop's display is configured " extend my desktop to this monitor", that's why you can only see the desktop background. Go to your display properties and change it to clone display or uncheck the extend display option.

SOURCE: "No signal detected" when LCD connected with DVI-D Cable

Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement

How to connect lp540 projector to hp computer


If using an laptop press and hold the FN key then press F4 or F8 and you may need to try this more then once to get it to the proper setting you need. If you are using a desk top with only one VGA output then should be just the cable and good to go, but if you are using two VGA outputs then you may have to configure the setting in control panel-display properties, for the 2nd monitor (projector).

Connecting an External Monitor or Data Projector
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

How can I connect BENQ MP510 multimedia projector with Acer Aspire one D255E notebook using windows 7? Do I need installation of extra driver for that?


Hi!


No you don't need a driver, connect it using a VGA Cable, then press FN Key at the same time with Fkeys that has a monitor screen Icon on your keyboard.

Hope this helps.

I have connected my Toshiba laptop to a benq PB6210 beamer but cannot get presentation on the screen. I need help


Hi there,

1) Turn off the BenQ power, before connecting your VGA cable to the Toshiba laptop.

2) Once your laptop recognises the BenQ unit, you then need to tell your laptop to send an output signal to the BenQ - you do this by pressing your 'screen output' button (this is usually one of the function keys and you may need to hold the key for 1sec). The output function key can choose either single VGA output, or both laptop screen + VGA output.

No LCD connectivity


Hello, I am using a Viewsonic lcd projector with my new Acer Aspire One. I did not have connectivity off the bat. Here's what I did: 1. Downloaded driver (unsigned, not the signed version worked - ie not os-specific) for the lcd projector to the Acer. Restart Acer. 2. With lcd projector connected to Acer, toggle function key & F5. But then, continue holding down the function key. A screen pops up with icons for laptop, laptop/monitor, dual monitor, and lcd projector. You continue to hold down the function key and then press the F5 key to move to the desired device. I had to repeat the same process to restore my Acer screen to the original proportion when not using lcd projector. I'm not sure if both steps 1 and 2 are necessary, but I did it simultaneously, so I'm not sure of the origin of success.

I just checked the specs on your Benq PB 6110, which has a native resolution of 800X600 and will simulate 1280X1024. When you connect it to your computer, the computer goes to 800X600, right? That is the resolution of the BenQ. How high a resolution do you want? THe highest I have seen in projectors is 1024X760, which is not that much higher. Projectors seem to lag behind monitors and Plasma/LCD/LED TVs for resolution. They must have a very small market share therefore low developement.

Philips DLP front view projector will not display my presentation


Most modern computers don't care which is plugged in first and/or turned on first... But, it can't hurt to have them both plugged in, then turn on the projector - then the computer. If the computer doesn't send a signal automatically on bootup, then you will need to tell it to...

On the function keys at the top of your laptop keyboard, there are some indications (most computer brands are different from one another so it might be one of several indications). Look for something that either looks like a small monitor or two, or label that says "crt/lcd" - this will be in a highlighted color that matches the color of your Fn key to the left of the spacebar. Fress "Fn" and the corresponding key at the top at the same time and you should get some changes from the computer. Depending on your video card, you might need to press it several times to cycle through the various settings of 1)computer screen, 2)display output only, 3)both computer screen & display output, and in some cases 4)no display sent.

Hope this helps! If not, I would check/try new or different cables from the computer to the projector in case you might just have a bad one.

Cannot see computer displyed on output of infocus screen shot


Many laptop computers do not automatically turn on their external
video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.

Try the Function Key with the Icon of a monitor to enable the external video port.

If that does work, look at the settings on the projector using the buttons on the top.

Check the "Default Source"

Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the
projector checks first for active video during power-up. Highlight
Default Source and click the left or right mouse button to toggle
among the options.

No signal for my lcd projector


You have to "Toggle" your PC to output the signal to the projector.

On which "F" key do you see "CRT/LCD" or a pictute that looks like a monitor?
