Hi I'm Joel, hopefully I can assist you today. Sorry to hear your having trouble with the external display
Once you have connected the projector. Can you press the Fn+F7 key and make sure you have the external display selected. Let me know how you go.
What model is the projector your using? Is it a HD projector?
Its possible the laptop has a much higher resolution and so the output device cannot display. Would also depend on if you are trying to mirror (display on laptop and the same on the monitor/projector) or whether you just want to output to the monitor/projector only. Have to tried cycling through those options, by using Fn then pressing F7 multiple times? You can also trying going into the display preferences on the laptop and setting it to a lower resolution and then see if the monitor/projector takes the signal. I am assuming the cable your using is fine and has worked in the past. Let me know if you've tried the above with no luck
No worries. If everything works fine with the other laptop then it must be one of the above with your new Lenovo. If you have tried lowering the resolution on the Lenovo, cycling through the output sources with Fn+F7 to no avail I'm out of ideas. Do you have any other external display or monitors you can try with the Lenovo?
I have also checked the Lenox manual and found the following section, though it just suggest similar stuff to the above.
Problem: The external monitor is blank.
Solution: To bring up the image, press Fn+F7 and select the desired monitor. If the problem persists, do the following:
1. Connect the external monitor to another computer to make sure it works.
2. Reconnect the external monitor to your computer.
3. Refer to the manual shipped with the external monitor to check the resolutions and refresh rates that are supported.
– If the external monitor supports the same resolution as the computer display or a higher resolution, view output on the external monitor or on both the external monitor and the computer display.
– If the external monitor supports a lower resolution than the computer display, view output on the external monitor only. (If you view output on the both the computer display and the external monitor, the external monitor screen will be blank or distorted.)
I would also try rebooting the Lenovo while the monitor/projector is connected to see if you get any signal.
Rebooting would drop the signal and return it, least it may cause the monitor/projector to flicker suggesting the signal is present but the output is not being processed.
If its an older monitor/projector, and it's receiving a HD signal 1080 or higher resolution which it cannot display it may just show up black, so dropping the resolution on the monitor may resolve that
Not sure what you mean by right drive? The RS232 cable your using works for the other laptop and same monitor/projector?
Where you able to test using the Lenovo with a different monitor?
No worries, sorry I couldn't assist further. Ill opt out so others can assist.

Okay, hold down the Windows Logo key and P key. Do you get external display setting for Duplicating, Extending, Projector only etc. ?
Hi. I looked up the specs on that projector. A 15-pin VGA cable from the laptop to the PC port on the projector is required to display the laptop screen. The RS-232c port is for projector controls. Use the remote control to select PC as the input.
That's ok. So when you have the laptop and projector connected and hold down the Windows key and press P
and select either Duplicate or Extend what shows up on the projector screen?
The Winkey + P should work but there's more than one way to do this.
Click Start, open Control Panel
In the search box, type projector, and then click Connect to a projector.
You may want to try the Windows key + P again.
Pressing Ctrl + P opens the print dialog and those two keys are right next to each other.
Got it working?
Right click on the desktop and select Screen Resolution. On that page click Detect.
If you connect the other Projector to this laptop is it working ? Do you have another VGA cable ? If so please use it to connect the projector to the laptop. If the vable is broken projector will not get signal from computer. If your projector has an option to select the input, please make sure you selected VGA as input.
Hi. This is kind of crazy. That projector should be working. I do have a question or two.
Was the laptop upgraded from Vista to Windows 7 or did it originally come with Win 7?
Is the Lenovo Presentation Director software installed on the laptop?
Thanks. Just checking.
Sorry for the delay in reply. If you connect the other Projector to this laptop is it working ?
Go here and check this BIOS update: http://support.lenovo.com/us/en/downloads/ds018805
Take a look at the README part as well.
