T530 multiple display configuration

I have the T530 with the NVIDIA Optimus option that should allow a triple display configuration (two external displays and the laptop LCD). 

 

I have been able to get a working configuration with the laptop LCD and two external displays over DisplayPort through the docking station. 

 

I have found that upon some boot cycles, I am either stuck with just the laptop LCD as the only display or I am able to turn on only one external display. Sometimes a reboot will change it, sometimes it will not.

 

What's strange is that the NVIDIA control panel and the Windows display settings show all three LCDs, I am just not able to turn on one or both of the external displays (even if I turn off the laptop LCD).

 

Has anyone found a solution to this problem?

 

Thank you!

Re: T530 multiple display configuration

Hi, admarsha

 

There are updates available for both your BIOS and Optimus that may help this issue. The BIOS update can be found here and the Optimus update can be found here. Looking over the ReadMe for the Nvidia update, part of the update does help with issues connected to multiple displays through docking stations so it may help.

 

Best,

Adam

Re: T530 multiple display configuration

Hi Adam,

 

Things have been stable for about a week but after a reboot today, this occurred again. 

 

I am able to enable one display on the NVS 5400M but not the other. I've tried both the NVIDIA control panel and the Windows Screen Resolution dialog. 

 

I'll try rebooting again later to see if that resolves the issue but that's not a workable long-term solution.

Re: T530 multiple display configuration

I wanted to update this post. The problem has come back and is back consistently. I am using driver 311.00 and I am still unable to turn on a 3rd display (LCD + 1 DisplayPort work and 1 DisplayPort does not work).

Re: T530 multiple display configuration

Hi again, admarsha

 

Sorry to hear this issue has resurfaced. Have you attempted to hook up external monitors to your machine without the docking station, i.e., one monitor with VGA and one with DisplayPort? If you have the ability to do so, I would recommend giving this a shot to see if this is possible. The issue could be with the GPU or the docking station, so determining which one is the issue would be best. Do you have the ability to do this?

 

Thanks in advance,

Adam

Re: T530 multiple display configuration

Hi Adam,

 

Thanks for the tip. I've identified two things:

1) connecting the non-working display to the laptop DisplayPort output works

2) disconnecting and reconnecting the working display to the dock will activate the non-working display

 

It seems like your idea is correct - there's something in the communication between the display and the dock that is causing a problem.

Re: T530 multiple display configuration

Hi again, admarsha

 

If you enter the BIOS and check the options under Config ► Display, what is the current setting of the graphics device you are using? I would definitely make sure that this is set to Nvidia Optimus if it is not already. Even if it is, switch it to Integrated Graphics and then give the docking station set up a try. I'm not expecting it to work the way that it should, but I would like to see how it behaves, i.e., if it works like it should with two independent displays, or if it is also having issues somewhere. In most docking station cases, the issue lies either with the systemboard or the dock. So, now we must find out which (if either) is experiencing a problem.

 

Thanks in advance,

Adam

Re: T530 multiple display configuration

Hi Adam,

 

I was finally able to try this.

 

 

The setting was set to Nvidia Optimus. 

 

When set to Integrated Graphics, only the built-in laptop LCD was functioning. I could not enable any other displays.

 

After resetting to Nvidia Optimus again, I am only able to use one of the two DisplayPort outputs again through the dock.

Re: T530 multiple display configuration

Hi again, admarsha

 

I believe that this is an issue with the connection between the motherboard and the docking station. You should be able to get at least one external display using the integrated graphics device. The fact that you cannot enable any others leads me to believe that the motherboard is not functioning quite right. This leads into issues with the docking station, since the dock connects directly to the motherboard. If one thing is not quite right on the motherboard, issues like the docking station with external displays often follow. I would recommend giving Lenovo Support a call at 1-800-426-7378 and discuss the issue with them, as well as your options.

 

Hope it helps,

Adam

Re: T530 multiple display configuration

I have the exact same problem. I've been using the T530 with docking an two external monitors and Windows 8 without problem. Today I upgraded to Windows 10 and started experiencing the problem described in this thread. Since my setup has worked flawlessly with Windows 8 I refuse to believe that this is a hardware problem. Any suggestions?
