I have just got the M83 but I am unable to get the dual display working.
I have one monitor plugged into the onboard slot and the other ino the Nvidia slot. I have tried changing the bios to the onboard card with multi monitors enabled but it still wont work.
I have also tried to update the drivers for both cards but I am told that they are up to date.
Both monitors work when the bios is set to the relevant card.

I have the same issue. I've tried every combination of VGA/Display Port, updated drivers and BIOS. I've tried leaving the display set to auto in the BIOS as well as manually setting it to IDG with dual-monitor support enabled. I've verified that both monitors are functioning properly.
I see that the last post on this was 7 months ago and received no response. Do Lenovo techs actually participate in these forums?

Can we revive this thread because I have issue very identical to this?
No concrete answer yet. Please confirm if we can't really use vga out of GT620 (nvidia) together with vga out of integrated gpu (intel). I tried everything as the original author stated.

Should be possible with the correct BIOS settings, I have used it on a M91p:

You do have "Multi-monitor support" enabled?

Still no resolution to this problem.
We have multiple M83s with onboard Intel HD 4600 graphics. BIOS is up to date and set to IDG with multiple monitor support enabled. We've updated all drivers and even reinstalled the video and chipset drivers. I also tried installing video drivers directly from Intel. Nothing seems to work; we cannot get any video out of the displayports.

Just to be clear, your M83 machines DO NOT ALSO HAVE A GRAPHICS EXPANSION CARD in them? They only have onboard Intel HD graphics, and you're trying to use one or two of the DP connectors (4) shown below in the schematic?
Or do they also have a graphics expansion card in the PCIe x16 expansion slot (13) in the schematic?

That is correct: there is NO graphics expansion card, ONLY onboard Intel HD graphics. We have tried a number of connector variations, VGA and DP1, VGA and DP2, DP1 and DP2. We can't seem to get any output from the DP ports. If we disconnect and reconnect the DP cable, the monitor is able to detect that something has been attached but the monitors go to sleep becuase there's no signal. And in case someone asks, the monitors work fine on VGA and we have tested with multiple monitors as well. The issue is not with the monitors.
