connect two monitors to XPS 15 laptop

Question

I have an XPS 15 laptop with thunderbolt and hdmi and usb ports. I want to connect it to two external monitors: 1. DELL P2715Q 2. LG 29UM68-P

the spec sheet for LG says:

HDMI 2 (ver1.4)

DisplayPort Yes (ver1.2)

there is a bit of instructions on how to do MST connections, but i am not sure if i can do it with this LG and how.

I am clueless on how to do it without any external adapters or whatsoever. Any tips or ideas?

Usually laptops only support two monitors at the same time. That means two external monitors work, but only of you disable the internal one. — confetti, Sep 01 '18 at 03:39

Run a HDMI cable to the LG and a Thunderbolt cable to the mini DisplayPort input on the Dell.

Am I missing something?

why thunderbolt to mDP and not DP ? any specific reason? – jacky Sep 01 '18 at 00:01
No specific reason other than your requirement to avoid adapters... Although these cables come in all flavors without separate adapters, some could be considered more "adapter like" than others :D – Your Computer Genius Sep 01 '18 at 00:10
so a USB C to DP to DELL and HDMI to HDMI on LG ? right? – jacky Sep 01 '18 at 00:13
Sure, you didn't link your laptop's ports spec, but if your Thunderbolt on there is USB C than yes. – Your Computer Genius Sep 01 '18 at 00:15
cool, yeah it is XPS 15 9560 and has hdmi and USB C, thanks – jacky Sep 01 '18 at 00:17
Great, have fun, you're welcome! – Your Computer Genius Sep 01 '18 at 00:18
it doesn't work, i attached a hdmi to LG and USB C to DELL monitor (USB C to DP) and it only shows on LG monitor. HDMI takes over the USB C. I am not sure if it is possible this way. – jacky Sep 02 '18 at 12:52

The following are the possible ways you could connect two displays on your laptop:

For DP MST, you can do this:
- Get a Thunderbolt-to-DP adapter and connect it to the Thunderbolt port of your laptop
- Connect the output of the adapter to DP-IN (port 4) of your DELL monitor
- DP-OUT (port 6) of the DELL monitor to the DP-IN of your LG monitor.
The next method is, connect one monitor via HDMI port and connect the other using Thunderbolt to any DP, HDMI, or a miniDP (for DELL-monitor only) adapter.
The easiest and most straight-forward solution might be to get a thunderbolt adapter with two DP outputs. Both of your monitors have DP-INs. Thunderbolt can support two dual 4K displays. So, you can easily find 1 thunderbolt adapter with two display outputs.
