No signal Displayport Dell Precision M4700

Hello:

1) I recently bought a  Dell Precision M4700 that has a Displayport, HDMI and VGA ports.

2) I also bought a Dell monitor U3011 that also has Displayport, HDMI and VGA port.

When I use VGA cable with VGA ports I am able to use dual (laptop screen and U3011).

But I would like to use Displayport to connect the U3011 to laptop. This setup used to work fine until yesterday.

Today I am not able to view/use my U3011 when I connect via Displayport (works fine with VGA).

How can I make laptop detect the U3011? The monitor says "there is no signal".

 

I don't have another laptop or monitor to troubleshoot the issues.

Here is what I did:

1) Upgraded the BIOS to A08

2) Upgraded NVIDIA Quadro K2000M Driver to version 9.18.13.1150

3) Upgrade other device drivers to latest releases.

 

Your help is much appreciated.

Hi katari,

If the monitor has driver’s disc, please install the drivers for the monitor.

If you do not have the disk please use this link to install the drivers for the U3011 monitor: http://dell.to/146JzDi

Click the above link, select the operating system, click Download file and install the drivers listed by following the onscreen instructions.

Try changing the input source to DVI by using the monitors “Onscreen display menu”. Refer this link: http://bit.ly/ZLAcno

Also please try a different Display cable to check if the problem is with the cable itself.

Kindly let me now the results.

 

Thanks & Regards,

Re: No signal Displayport Dell Precision M4700

Hello Nikhil:

Thank you for answering my post.

As you suggested I installed the Dell Monitor drivers. But that did not help.

In addition, Dell technician replaced the mother board on laptop (to eliminate the possibility of ports gone bad).

In addition, we also found out that HDMI is also not working out. VGA is working fine.

I don't think both HDMI and Dispalyport cables are bad.

The two possible problems:

1) Some kind of software configuration on laptop.

Since the configuration was working until last week, I am not sure what could have been changed.

I double checked various settings, etc.

When we plug in the cables monitor wakes up searches and says no signal found. No activity is detected on the laptop.

2) Ports on the monitor have gone bad.

I was able to use Dell Allienware (older laptop) and connect to the monitor using HDMI. The Displayport does not work with the Allienware.

The same monitor does not work with Dell Precision M 4700, as described in earlier posts.

This makes me think some kind of driver combination or configuration is causing conflicts.

Re: No signal Displayport Dell Precision M4700

Hi katari,

As the monitor is not working on both the systems, the problem could be with the ports on the monitor.

I would like to know if you have changed the ‘Input source’ on the monitor to DVI or HDMI before connecting the cables.

Please check and reply.

Thanks & Regards,

Re: No signal Displayport Dell Precision M4700

Hello Nikhil:

1) I did change the "input Source" to appropriate input source every time I changed connectivity.

2) The HDMI works fine with both Allienware and M4700

If the HDMI did not work on Allienware, I would have though the ports are bad on the monitor. The monitor is only couple of months old.

3) DisplayPort does not work for both. I am guessing since Allienware is about 4 year old laptop, DisplayPort specs may have changed.
