@XPSinCapeTown Happy to help, and thanks for that link! Between the two, I would personally get the U2421E, for three reasons:
The 90W output might be useful with other laptops.
USB 3.x Gen 2 (10 Gbps) support
The P2421DC uses 2560x1440 resolution on a 24” display. That results in a pixel density that is higher than most people can use comfortably without enabling scaling, and if you have to enable scaling, then you lose some of the benefit of the additional workspace that would normally come with having more resolution. Plus some Windows application still don’t support display scaling very well. So at that point, I’d probably just enjoy the fact that the U2421E uses 1920x1200 resolution rather than the more common 1920x1080. The extra 120 vertical pixels might not sound like a lot, but I’ve used both and definitely prefer the latter if I can’t get 2560x1400 on a 27” display where that extra resolution can be put to good use.
I would say if you’re getting a 24” display, go with 1920x1200, or even just 1920x1080 if the savings is significant over the U2421E.
@XPSinCapeTown There are quite a few aspects to your plan here, so I'll address them in turn. But settle in.
Daisy chaining only works with DisplayPort, not HDMI (with one special case exception where HDMI can be used for the last display in the chain). So you couldn't use your DA100 as the source of a daisy chain setup, because that would mean you're starting with HDMI. And even Dell's DA300 that has a DisplayPort output is confirmed not to support DisplayPort MST, which is required for daisy chaining. It only supports a single display, so it can't be the source of a daisy chain either.
If you want to run multiple displays, Ethernet, and USB all through a single port on your system, one option you may want to consider if you'll be buying a new display anyway is what Dell calls a "USB-C hub display", which is essentially a display with a built-in docking station. Dell has 24" FHD and 27" QHD displays that include Ethernet and support daisy chaining, for example. The current models of each are the U2422HE and the U2722DE. Each can supply up to 90W of power (the XPS 13 only requires 45W, but you'll have some futureproofing) and support Ethernet, 3.5 mm audio output, USB 3.x Gen 2 (10 Gbps) and a daisy chain output. And since your existing P2717H has a DisplayPort input, you can just connect it to the first display using a regular DP cable, which is included with the two new displays I just mentioned.
But there is one catch to the above. The XPS 13 9360 only supports DisplayPort 1.2/HBR2 over USB-C. And due to the way USB-C works, if you want USB 3.x data speeds available, video bandwidth gets cut in half. A half-bandwidth HBR2 link is only enough for dual displays up to 1920x1200 each. So if you went dual FHD, you could run that and USB 3.x simultaneously without any issues. But if you want to run QHD + FHD, it's a bit different. The new displays I mentioned above can be configured to set up the USB-C link to maximize video bandwidth, which allows them to tap into enough bandwidth to run up to dual QHD, but the catch is that you'll be limited to USB 2.0 data speeds for anything connected to the display's USB ports -- and since the built-in Ethernet runs over USB between the display and system, you'll bottleneck a Gigabit Ethernet connection this way as well. A slightly messier setup would be to run a QHD+FHD daisy chain in USB 2.0 mode and then get a separate USB 3.0 hub to connect directly to the XPS 13's USB-A "regular USB" port. You could plug a Gigabit Ethernet to USB adapter into that if you wanted. They're not that expensive.
Otherwise, if you don't want a display with a built-in dock and/or you want to be able to run QHD+FHD and USB 3.x all while maintaining single cable connectivity to your system, your only option with that system is a Thunderbolt 3 dock. Dell's current TB3 dock is the WD19TBS.
@XPSinCapeTown I forgot to address your last question. The Intel GPU built into the XPS 13 9360 only supports three simultaneous independent displays, regardless of resolution or how they're connected. This limitation is separate from and in addition to any other constraints that might prevent a specific display setup, such as available ports, available bandwidth, etc. If you had a Thunderbolt 3 dock, you could run triple displays up to QHD each (or I believe 4K 60 Hz + dual QHD), but you'd have to disable the built-in display to do that. If you want to run a daisy chain, you'd be limited to triple FHD even in the "USB 2.0 mode" I described above. The reason for the difference is that TB3 with your system can tap into two full DP 1.2 interfaces and still have enough bandwidth for other things like USB 3.x data, while a regular USB-C video output on your system only has either a full DP 1.2 interface or half of a DP 1.2 interface, depending on whether you want to run USB 3.x simultaneously.
The only way you would be able to add more displays would be with solutions that relied on "indirect display" technology such as DisplayLink -- not to be confused with DisplayPort. Since those displays are driven indirectly, they don't count toward the GPU's maximum display count. There are single display USB dongles and even entire docks built using DisplayLink technology, but the way DisplayLink works has some drawbacks that I've written about in the post marked as the answer in this thread.
I do not mind to continue to use the DA100 to enable the USB hub of the P2717H - and for Ethernet. So - if I buy a monitor like the P2419HC and then daisy chain from it to the P2717H - will that give me video? The HDMI on the DA100 will then not be used.
The challenge is that the monitors you mentioned is not available in South Africa - and it seems the docks are the price of a screen - so I am thinking to buy smaller (24 inch) so that FHD is enough and then try and link them up without the need for a dock
Sorry - I forgot to mention that what I hope will work is to get a Thunderbolt (or would it actually be a USB-C) to DisplayPort cable to connect the laptop to the P2419HC - and then another cable (DP to DP) to connect the second screen. Will that work?
@XPSinCapeTown Happy to help. And apologies, when writing my original reply, I forgot that the DA100 connects to a USB-A "regular USB" port rather than a USB-C port like the DA200, DA300, and DA310. That actually makes the DA100 a bad choice for video output in at least some cases because its reliance on DisplayLink "indirect display" technology can create some drawbacks, but that's not really worth getting into at this stage. It's also limited to 1080p output.
But I now understand the scenario you're envisioning. And actually you've got an improvement you can make even today. The DA100's USB port is limited to USB 2.0, whereas your existing P2717H has some ports that support USB 3.0, so your DA100 is currently bottlenecking your USB performance. The better cabling solution would be to connect the display's USB interface directly to your system and then plug the DA100 into a USB 3.0 port on the display. You could do that right now, even while using the HDMI output of the DA100. It would look a bit strange to have a DA100 plugged into a display's USB port and then having an HDMI cable running from that DA100's output to the HDMI input of that same display, but it would absolutely work, and it would remove the USB 2.0 bottleneck you've got right now.
And in terms of South Africa availability, Dell has older 24" FHD and 27" QHD displays that have USB-C inputs and daisy chaining support. There's the P2419HC, U2421E (1920x1200 rather than 1920x1080), U2719DC, and U2721DE. The ones with an "E" have built-in Ethernet, but you can already use your DA100 plugged into the display's USB port for that. And some only supply 65W of power rather than 90W like the latest displays, but that's still enough for your XPS 13. And I deliberately did not mention any P Series 27" displays, like the P2720DC, since they don't offer the option to set up "USB 2.0 mode", which you'll need in your setup from that system if you go with a QHD display. The U Series 27" displays have it -- but here again you'll have a USB 2.0 bottleneck that will affect built-in Ethernet or the DA100 running through the display in that case.
But if you can't get any of those either, then yes you could get a USB-C to DisplayPort cable to connect to one display and then daisy chain from there to another one. I've used that setup myself. And since in that case you won't be running any USB data at all over that cable, you can run up to dual QHD that way. But here again, I'd connect the DA100 to a USB port on the display, not run the display's upstream USB connection through the DA100.
In terms of the P2419HC product page saying "Daisy Chain Availability: No", that's just an error. The Overview section of that same product page says "Connect to productivity: Easily daisy chain up to two FHD monitors with DisplayPort 1.2 output." When researching products, I often find that just reading the manual is a much more reliable way to learn about its capabilities than reading product pages.
@XPSinCapeTown I just checked the P2717H specs and it seems only the USB ports on the left side are USB 3.0, whereas the bottom ports are USB 2.0. In that case, to avoid a bottleneck you'd have to connect your DA100 on the left side where it would be dangling off the side of the display, which may or may not be acceptable to you. But if not, if you got a new display that had USB 3.x ports even along the bottom edge, which newer displays typically will, then you could connect your DA100 there and probably keep it out of sight.
Great this is all very cool info. I need to make sure I understand. After you list the monitors that will work you wrote "But if you can't get any of those either, then yes you could get a USB-C to DisplayPort cable to connect to one display and then daisy chain from there to another one"
Even if I get hold of a HC screen I would still need a USB-C to DisplayPort cable - right? How would I connect the new screen to the XPS? Am I missing something?
And - the USB C will plug in to the Thunderbolt slot of the XPS?
And - will I plug the power in to the new screen - and it will provide power to the XPS? Not very familiar with what can happen over USB - C
Last one - I think I have read somewhere in one of your other answers that you do not recommend closing the XPS and using two external monitors. Did you write that? Maybe I read it somewhere else. If yes - why?
The Dell display models that end with a "C" have an actual USB-C input on the display itself. The ones that end with an "E" have that plus built-in Ethernet. If you get a display like that, you will not need a USB-C to DisplayPort cable, because you will instead use a USB-C to USB-C cable -- and that cable will send video to the display, receive power from the display, and carry USB data between the system and display's USB devices (and built-in Ethernet if available), all over that single USB-C to USB-C cable. So instead of needing a USB-C to DP cable for video, a USB 3.0 cable for USB data, and a power cable, you'll be down to a single cable. And if you have currently have external speakers that you plug into the XPS's 3.5 mm audio jack and you get a U Series display that has a USB-C input, you can even connect your speakers to the audio output jack on the display instead, which will eliminate yet another cable connection you'll have to deal with on your XPS.
You only need a USB-C to DP cable if you get a display that does not have a USB-C input. But then you'll need to use separate, additional cables for power, USB data, Ethernet, audio if applicable, etc.
But either way, you would use a regular DP cable to connect the DisplayPort output of the first display to the DisplayPort input of the second display. And either way, you would plug the first display into the XPS through its USB-C/TB3 port.
I don't think I was the one who recommended against closing the XPS lid and using dual external displays, especially given that I personally used an XPS 15 9530 for about 6 years and during the vast majority of its time, it was sitting on my desk with its lid closed and two external displays attached. I have however recommended against the opposite setup, i.e. trying to use the XPS built-in display and external displays simultaneously. The reason has to do with the pixel densities of the various displays involved and limitations around Windows display scaling, especially when you can't use the same scale factor on all active displays. But that's a longer discussion.
I got the new U2421E yesterday. What would be the best way to connect the USB hub of the P2717H? I have connected the U2421E with my laptop through the USB-C Cable (C to C) - but there does not seem to be a way to connect my laptop to the U2421E using USB A - is that a problem? I plugged the USB A cable that was plugged in to my laptop from the P2717H in to one of the U2421E's SUB A ports - but now the data for that is flowing over the C to C cable - is that a problem? There is a USB A to C cable that came in the box left over - is that supposed to be used when HDMI or DP is used for video?
@XPSinCapeTown If your laptop is connected to the U2421E via USB-C to USB-C cable, as it should be, then the most convenient way to use the USB ports built into your other P2717H would be to use a USB-B to USB-A cable, also known as a "regular USB 3.0 cable" to connect the upstream USB 3.0 port of the P2717H to any of the USB-A ports on the U2421E. That will be functionally identical to connecting one USB hub (built into the P2717H) to another USB hub (built into the U2421E). And yes, in that case the USB data will flow over the USB-C connection between your laptop and the U2421E, but that isn't a problem at all. In fact if your laptop only has a single USB host controller chipset for all of its ports, which is typically the case on laptops, then connecting the P2717H directly to your laptop won't improve performance at all because the bandwidth limitation is the single chipset controlling all of the laptop's USB ports anyway. The only case it might be helpful to connect the P2717H directly would be if you encounter some issue running peripherals through two USB hubs, but those issues are fairly rare.
Yes, the USB-C to USB-A cable is meant for scenarios where you're using a different input for video, possibly because your system doesn't have a USB-C port that supports video output -- such as many desktop systems.
I have a XPS 13 7390 and now 3 P2422 HE monitors. And no dock station.
After disabling my laptop's screen I have connected my laptop to the first monitor using USB-C and the other two serially using Daisy with HDMI cables. The third monitor has a resolution limitation, as you may imagine.
Is there a solution here without having to buy a dock station?

@XPSinCapeTown Ok, I see the confusion now.
The Dell display models that end with a "C" have an actual USB-C input on the display itself. The ones that end with an "E" have that plus built-in Ethernet. If you get a display like that, you will not need a USB-C to DisplayPort cable, because you will instead use a USB-C to USB-C cable -- and that cable will send video to the display, receive power from the display, and carry USB data between the system and display's USB devices (and built-in Ethernet if available), all over that single USB-C to USB-C cable.

Thank you so much for all the help again jphughan
I am planning to get the P2421DC (the 27 inch monitors that use USB C and can daisy chain with DP is just to expensive)
To say thank you I thought you would like this site https://designcompaniesranked.com/resources/is-this-retina/

Hi jphughan
I got the new U2421E yesterday. What would be the best way to connect the USB hub of the P2717H? I have connected the U2421E with my laptop through the USB-C Cable (C to C) - but there does not seem to be a way to connect my laptop to the U2421E using USB A - is that a problem? I plugged the USB A cable that was plugged in to my laptop from the P2717H in to one of the U2421E's SUB A ports - but now the data for that is flowing over the C to C cable - is that a problem? There is a USB A to C cable that came in the box left over - is that supposed to be used when HDMI or DP is used for video?

@XPSinCapeTown If your laptop is connected to the U2421E via USB-C to USB-C cable, as it should be, then the most convenient way to use the USB ports built into your other P2717H would be to use a USB-B to USB-A cable, also known as a "regular USB 3.0 cable" to connect the upstream USB 3.0 port of the P2717H to any of the USB-A ports on the U2421E. That will be functionally identical to connecting one USB hub (built into the P2717H) to another USB hub (built into the U2421E). And yes, in that case the USB data will flow over the USB-C connection between your laptop and the U2421E, but that isn't a problem at all. In fact if your laptop only has a single USB host controller chipset for all of its ports, which is typically the case on laptops, then connecting the P2717H directly to your laptop won't improve performance at all because the bandwidth limitation is the single chipset controlling all of the laptop's USB ports anyway. The only case it might be helpful to connect the P2717H directly would be if you encounter some issue running peripherals through two USB hubs, but those issues are fairly rare.
Yes, the USB-C to USB-A cable is meant for scenarios where you're using a different input for video, possibly because your system doesn't have a USB-C port that supports video output -- such as many desktop systems.

@jphughan ,
If you could also help me...
I have a XPS 13 7390 and now 3 P2422 HE monitors. And no dock station.
After disabling my laptop's screen I have connected my laptop to the first monitor using USB-C and the other two serially using Daisy with HDMI cables. The third monitor has a resolution limitation, as you may imagine.
Is there a solution here without having to buy a dock station?
Thanks
