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.
Thank you very much for taking the time to reach the Intel® Communities Team.
I understand you are having some issues when setting up a third monitor to your Lenovo™ system. I will be more than glad to assist you further.
In this case, for me to provide you better assistance, I would like to gather more information about the configuration you have on the computer.

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.
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.
Again, you are responding to a very old conversation about a very old - and long discontinued - product. Intel Customer Support is not going to involve themselves in the resolution of this issue, so it's just us riffraff.
There have been a number of cases where attempts to simultaneously connect three monitors using 2500 graphics did not succeed. Dell platforms seemed to come up in most of these cases. I have only seen tripple monitor configurations be successful when using 3rd gen processors with 4000 graphics. Still, the specs say that this should be possible. If it is, I believe it may only be possible using just the DisplayPort ports.
You can connect two (or even three) monitors to a single DisplayPort port using daisy-chaining, but this is only possible if at least one (or two) of the monitors provides built-in support for DisplayPort daisy-chaining. The other, simpler way is to use an MST Hub device. Here is an example of a DP-to-2xDP MST Hub device: https://www.amazon.com/dp/B09NCQC3V4. If you want a DP-to-2xHDMI MST Hub device, here is an example of one of these as well: https://www.amazon.com/dp/B09JL3QT2S.
Hope this helps,
