My Dell just installed a new driver for the graphics card and once that was done I can only get 2 of my 3 monitors to be recognized. I tried going to the device manager and rolling back the driver to the previous version that was working without any problems but its not showing that option now. Any suggestions?
Win 10, 64 bit, CPU, 1 monitor on VGA, 2 monitors on display ports.

What is the model number of your processor, and what is the model number of your laptop/desktop?

Your processor does support 3 monitors. How Dell has implemented this with their latest driver is a question you should ask dell.

Were you ever able to figure this out? I am having the same exact issue.

I answered you in the other conversation. Unless you have get MST to work, Dell's design limits you to two monitors.

MST means Multi-Stream Transport. It is a capability that allows a single DisplayPort stream (port) to support more than one connected monitor. It can be used two ways:
- You can purchase MST Hub devices that provide you with two or more downstream DisplayPort ports. There are even some that include the converter chips and give you HDMI ports instead!
- You can also purchase monitors that have support for MST built in. You connect the first monitor to the system's DisplayPort port and the second monitor to the first monitor's DisplayPort output port. A third monitor can similarly be connected. This is also called DisplayPort Daisy-Chaining.
For either case, the limit is three monitors total; that is all that Intel HD/UHD Graphics engines can support. As well, understand that the monitors are sharing the bandwidth of the one DisplayPort channel. While this is no issue for 2K monitors, 4K monitors will have resolution and/or refresh limitations.
Now, all that said, the issue is whether the system - including its BIOS - has support for MST included. If it doesn't, this doesn't work. In the original conversation, the OP purchased a device but it didn't work. You could try doing this yourself with your system, but Dell doesn't have a great track record here.
Hope this helps,

your the man N_Scott. While I'm still in the same spot I was yesterday, trying every possible thing, at least I have some closure now.
