Intel HD Graphics 2500 - enable multi-monitor (3 screens)

Okay, so I've been all over the internet trying to figure out how to extend my screen to a third monitor.

In the native Display Properties I receive this error every time I try to extend

But in the Intel Graphics Options, I'm never given the option to include the third monitor.

In each section, I can choose from the three monitors but can never detect or add the third monitor, even though everything from Intel and Lenovo state that it should be possible.

I have the devices connected via 2 Display Port and 1 VGA.

Hello Antony,

Thank you for your reply. I've attached the system scan you requested, and am anxious to hear if it's just something simple that I'm missing to extend a third monitor.

Hello, TheBaileyBrew.

 

 

Thank you very much for your reply and the report provided.

 

 

Using the report provided I can see that thehttps://ark.intel.com/products/65703/Intel-Core-i5-3470T-Processor-3M-Cache-up-to-3_60-GHz Intel® Core™ i5-3470T that your https://support.lenovo.com/us/en/solutions/pd024438 Lenovo™ system has will allow 3 monitors to be connected simultaneously nonetheless, there are some things that we need to take into consideration when setting up a multi-display set up.

 

First, I see that your computer is having one VGA port and one Display Port connector so you should be using a dongle in order to achieve the 3 displays connection. Please verify the compatibility between dongle, the computer, and the monitors or, if this dongle is completely functional.

 

Then, please check the bandwidth used connecting these two first monitors since the Intel® HD Graphics controller will not identify the third monitor if the bandwidth exceeds the maximum allowable limit.

 

And, please find the following link with a guide of how enable extended desktop mode with multiple displays: https://www.intel.com/content/www/us/en/support/articles/000005599/graphics-drivers.html https://www.intel.com/content/www/us/en/support/articles/000005599/graphics-drivers.html

Hello again Antony,

I've gone as far as taking my screens down to 1280x768 to try and cut bandwidth even though Intel's Max resolution documentation states that 1920x1080 should be sufficient, but I still see the same errors and no ability to add a third screen.

The Graphics Control panel shows all three monitors in each of the drop downs, but I can't find anywhere to actually allow for a third to be selected.

Hello, TheBaileyBrew.

 

 

Thank you very much for your reply.

 

 

Allow me to share with you that the graphics controller installed on your system will definitely allow 3 monitors be connected to it nonetheless, there might be a physical restriction which will not allow this in your Lenovo™ machine. The Intel® Graphics controllers features can be manipulated by the manufacturer of the mainboard. I will highly recommend you to get in touch with https://support.lenovo.com/us/en/ Lenovo™ Support directly so you can confirm if there is another method to achieve this or if it is not possible.

Hello, 

 

Same problem for me. I have 2 digital monitors connected to the DisplayPorts and one in the VGA and it is impossible to have the three working at the same time.
