Multiple external monitors with Dell Precision M4700

I just got a Precision M4700 with Windows 8 64bit and an AMD FirePro M4000 graphics card. According to the Dell website and to other articles I have read, in addition to the laptop's built-in display I should be able to connect to two other displays without the docking station or five other displays with a docking station. However, so far I have only been able to get one external display to work even if I use the docking station. If I use certain ports I can get two external displays to work, but only if I disable the built-in display.

Without the docking station, the laptop has one HDMI, one VGA, and one DisplayPort. I have tried connecting my two external monitors to these ports in every possible combination. Every time I connect the second external monitor it is detected in the Windows "Screen Resolution" dialog but defaults to disabled. If I try to enable the display and click "Apply" then I get this message:

"The display settings could not be saved. Please try a different combination of display settings."

After I first had this issue with the default drivers pre-installed by Dell, I tried updating to the most recent driver available from the AMD website and I still get the same issue.

Any ideas are much appreciated.

I fixed the problem. AMD Eyefinity cards require that you use DisplayPort but it supports up to two "legacy" displays (DVI, VGA, etc). The built-in laptop display counts as one legacy screen, so it only allows for one other non-DP monitor. I was using DisplayPort but I was connecting to a DVI monitor using a PASSIVE adapter. If the adapter is passive then the video card still outputs a DVI signal and that causes it to count as one of the legacy displays. I got two ACTIVE DP to DVI converters and now I have three monitors + built-in display and it works fine.

So I realize the last post here was from Feb 2015 (almost a year ago), but I wanted to offer up my two cents in the event someone comes across this as I did.

I have a Dell Precision M4700 with the nVidia Quadro K1000M AND Intel HD Graphics 4000. I have a docking station at my desk and due to space limitations, do not open the lid of my laptop anymore. What I did was just ran 2 DVI cables directly from the docking station to 2 external monitors, and then as a test, took a 3rd monitor out of our server room and connected it to the VGA port on the docking station. All three work great with no issues. Obviously I'm not getting as high of resolution out of the VGA connected monitor as with the two connected via DVI, but the VGA one (being a spare) is slightly bigger anyway (24" vs my (2) 21.5" bezel-less monitors).

Either way, just thought I'd mention that if you have a docking station for your Precision, you should be able to use 3 external monitors.

***Side note: as I was typing this, I decided to be thorough and open the lid of my laptop. I do have 4 active monitors working with this configuration. 3 external monitors AND my laptop screen are all lined up (had to enable them all in the Display Settings) and working just fine. Desk space will keep me from using this configuration at the moment, but now that I know I can achieve this, I will probably rearrange my office/desk to take full advantage of using 4 monitors...sweet...

Where did you buy your adapters?

I used two of these: www.newegg.ca/.../Product.aspx

AMD lists officially supported adapters: support.amd.com/.../eyefinity-dongles.aspx

Fantastic thanks! Picking up two tomorrow. CEO will be pleased!

It was very easy to add 3 external monitors in my M4700. Please note that No 1 is the laptop's screen. The last monitor is in Portrait mode.

No 2 is a Dell 24 IPS monitor (notice that that the vertical resolution is 1200 - not 1080 - that's why image extends further down than other 23 inch monitors)

A multiple monitor setup is quite productive for Excel VBA development

We got the 4 monitors + 1 laptop screen working great after ordering Active DVI adapters for the computer
