You should read this first: Frequently Asked Questions for Multiple Displays
The cables used will depend on what connectors the displays have and what connectors the docking port has.
Your processor supports up to 3 displays: Intel® Core™ i5-6300U Processor (3M Cache, up to 3.00 GHz) Product Specifications
The use of adaptors is not supported or recommended.
There are plenty of cables out there that do not require adapters. For example:
mini-DP to DP
DVI to HDMI
You can find such cables on Newegg or amazon, for example.
You should enlist the help of your IT/Service Desk department or a computer support shop, or even DELL (who also sells such cables).
You should also check with dell for their laptop and BIOS support of 3 monitors.
I have not found useful info in that article.
I do know that the laptops can support three monitors with HD Graphics 520.
We are the IT for our organization and have now tried several cables.
We can get 2 monitors working with 1 VGA connected to main display, an HDMI>VGA adapter connected to HDMI port of dock to VGA on 2nd monitor. That said as soon as I connect a mini display port to display port cable for my third monitor it will ONLY display in 680x450 resolution. The other 2 stay at 1680x1050.
Can you advise why the third monitor will only put out 680x450?
With the port info listed in the post, can you advise a specific setup that will work, as to not lose any more time with mixing and matching and buying cables?
Thanks for your time.
DELL's guide tells pretty much the same as Al_Hill
Monitor Resolution Issues
Another issue that you may come across is that your monitors may not display at their maximum or native resolution. These steps can assist you with this issue.
Verify the optimal resolution of your monitors. Again, for Dell monitors, you can verify this by reading the Monitor's manual: www.dell.com/support/manuals
Also, verify that your video card or video chipset can output at the optimal resolution for your monitors. To do this, please visit your video card or video chipset manufacturer for further information.
Updating the video drivers can resolve any resolution issues that you may experience. To do this, follow step 7 from the section above.
Adapters that are used in your multiple monitor configuration can cause resolution problems (for example, using a single link DVI adapter when your monitor may have a native resolution higher than that provided by single link DVI). If you are able to, try removing adapters and only use the cables to connect your monitor and system.

found the issue its a limitation with the dock itself. I would recommend manually lowering the resolution and adjusting the refresh rates in Windows the best you can to get it working.
Supported Display Resolution
Passive Cable or Universal Cable without Thunderbolt™ System Single Display (maximum resolution) Dual Display (maximum resolution) Triple Display (maximum resolution)
- miniDP (DisplayPort): 2560 x 1600 @ 60Hz
- HDMI: 1920 x 1200 @ 60Hz
- VGA: 1920 x 1200 @ 60Hz
FHD (1920 x 1080) or WUXGA (1920 x 1200) @ 60Hz SXGA (1280 x 1024) @ 60 Hz
Table 3: Display Resolutions supported by the docking station using a Passive Cable or Universal Cable without Thunderbolt™ system.
Note: For dual or triple display, you may use mDP, HDMI or VGA to connect your monitor. The maximum resolution will depend on the resolution supported by the monitor and the maximum resolution that is supported by Dell Dock WD15 in dual or triple display configuration.
Note: Quad Displays are not supported by the Dell Dock WD15.
Note: Some resolutions may not be supported and hence will be removed from the Intel Graphics Control Panel. Resolution support is also dependent on the monitor's Extended Display Identification Data (EDID) resolution.
