This topic explains exactly my current problem. I have both an XPS15-9550 and an XPS15-9570. When I connect an external monitor through a HDMI to DVI cable, the XPS 9550 works fine. When connecting the 9570 to exactly the same setup, the message 'no signal input' appears.
The mentioned topic does not really provide a solution.
@Wordpad the thread above does touch on the point. Put simply, DVI has been superseded by HDMI and DisplayPort technologies. Intel, AMD and multiple other companies have reduced support for the technology as a result of this with them. This is why the older XPS supports the technology but move through a few years of development to the 9570 and it no longer works.
How old are your monitors and do they have other video connector options?
Thank you for your response. The monitors are indeed quite old, but are used extensively on the customer's site. They cannot replace them all at once because there are too many of them, but if they want to use them, they wouldn't be able to use new XPS'¿
The monitors provide a DVI and VGA connection.
I understand your argument, but I don't find DVI 'that old'. And especially for the price of an XPS, I don't really want to be limited in choice of connections or peripherals.
This is indeed a strange issue because single-link DVI (up to 1920x1200) is supposed to be 100% identical to HDMI at an electrical signaling level, so I was actually surprised to discover that it was even possible for an HDMI output to work properly with HDMI but not with DVI. But I too have read the threads about this issue on the XPS 15 9570.
It would be nice if Dell could offer a better explanation about this in a KB article somewhere -- or better yet, an actual fix -- but unfortunately I'm not holding my breath. Recently it was discovered that on the XPS 13 9350 and XPS 15 9550, their USB-C outputs didn't provide a video signal when they were connected to certain Dell USB-C displays using a USB-C cable. That was the case even though those systems could send video over regular USB-C cables to other USB-C displays just fine, and those Dell displays could accept video over USB-C from other devices just fine. In fact, those systems could even send video to those displays from their USB-C ports if the user had something like a USB-C to DisplayPort adapter/cable, although that wasn't ideal because in that setup, your connection no longer carries USB and power. So the problem condition was very narrow and therefore strange. Dell responded with a KB article about this (which only mentions the XPS 13 because the discovery relating to the XPS 15 model of the same generation didn't occur until later), but the KB article basically just acknowledges the issue and then says that the issue won't be fixed because the XPS 13 model in question is end-of-life, but that users can work around this by placing a docking station between the system and the display. There was no indication of any sort of fix or even an explanation of the underlying cause.
Hi Alan, You might be right, but I still find it strange that the tech is available on an older model and you wouldn't/couldn't implement that on the newer model. I understand there are plenty of factors to consider, but now it doesn't live up to my expectations. As a customer I'd like to replace my older XPS with a newer XPS (from the same series) without any change in peripherals or other hardware and end up in a working situation. The screen is replaced for a different one in the meantime (now a EliteDisplay E231) which does have a DisplayPort, but now both the 9550 and the 9570 give no screen output. The 9550 does give output via the previously used HDMI - DVI cable, but the 9570 does not. I'll see if it's the displayport cable or anything else, but it'll take time. I've also ordered some aftermarket gadgets and docks to try out, to see how this goes.

@Wordpad it's the industry that has defined the technology as old, not us. Windows 10 has stopped supporting VGA for years however we still provide a VGA port on the majority of the wireless docking station solutions.
For DVI, its a technology that has been superseded and you will struggle to get new kit which supports it, especially notebooks and docking stations. The industry has adopted HDMI, Display Port and now USB-C as an improved video standard.
For your XPS there are plenty of video options via a dock apart from DVI.
@Wordpad how are you connecting to your new DisplayPort-equipped display? If you're using a DisplayPort to HDMI cable, that won't work because those cables are only designed to allow a DisplayPort source to send a signal to an HDMI display, not the other way around. The reason is that most DisplayPort outputs support "Dual Mode DisplayPort", sometimes written DP++, which allows them to fall back to HDMI signalling for compatibility, but HDMI sources can't send a DisplayPort signal (and displays can't accept a native HDMI signal on their DisplayPort inputs.) You'd need a USB-C to DisplayPort cable to use newer XPS systems with a DisplayPort display, or a USB-C to DisplayPort dongle plus a regular DisplayPort cable if you prefer.
@Francis M HDMI to HDMI should work without issue on the notebook. There is an HDMI port on the left hand side of the laptop.
Once connected to the monitor, ensure the monitor input is set to HDMI. Once done the only changes you will want to make is for your screen properties to ensure Windows recognises the external monitor and runs at the correct resolution for the monitor. Then you can choose whether you want to extended the laptop display or duplicate it.
To do this, right click on the desktop and select Display settings
Then configure your display using the options presented
Would I be able to use this to connect my HDMI to DVI monitor to my XPS 9570? I also want to connect another monitor via the display port & use this dock with a mac book pro 2019
Or is that not an option, and I'd have to buy a proper dock this.
@CallmeJimmy95 I haven't personally tested the DA300 with an HDMI to DVI cable, but my bet would be that it would work. There seems to be something going on with the system's own HDMI output that prevents HDMI to DVI cables/adapters from working, but the DA300 would involve the system sending a DisplayPort signal from its USB-C port and then it would have a converter built to switch that to HDMI. So at that point the ability to use DVI would depend on the particulars of the DA300, not the XPS 15. And since HDMI to DVI cables/adapters work in the overwhelming majority of scenarios -- the XPS 15 9570's built-in HDMI output still remains the only situation I'm aware of where that isn't the case -- I suspect that it would work.
But if you were to get a WD19 dock, you'd want the version that came with the 180W adapter since you would be powering an XPS 15. You linked the 130W version. The 130W version can only pass 90W to attached systems, whereas the 180W version can pass 130W to attached Dell systems, and systems like the XPS 15 that are designed for 130W are the reason that the 180W version exists at all.
@CallmeJimmy95 the DA300 only supports one display at a time. I'm pretty sure that's mentioned in the documentation and that a sticky label attached to the DA300 from the factory has a graphic that spans all display outputs and has a "1" in the middle of it. Sorry, when you said you also wanted to use it with a DisplayPort display and with a Mac, I didn't realize that you meant you wanted to use those displays simultaneously.
I don't know of any "mini-dock" like the DA300 that supports multiple displays AND these various connectors. There are things like USB-C DisplayPort MST hubs and Thunderbolt 3 to Dual DisplayPort adapters that will run multiple displays but don't have other ports, and then there are mini-docks that provide a variety of ports but don't support multiple simultaneously displays. My guess is that the cost of a device that combined those capabilities would be too high and too close to a dock, and most people who need those capabilities would probably prefer a dock anyway since it would also charge their system. Mini-docks are meant to allow you to connect to a TV, projector, or some other single-display setup on the go -- or possibly to use for a basic home setup. Most people don't need to plug into dual display setups on the go (or the dual display setup might also have a dock already there), and if they're plugging into their own home dual display setup, then a dock would typically be a viable and preferable choice.
As for the WD19, since you're using the XPS 15 you'd need to get either the WD19 w/ 180W power adapter (not the 130W version it's also available with) or the WD19TB (comes standard with a 180W adapter). The 180W version is necessary because that's the only way the dock can pass up to 130W through to the attached system, which is what the XPS 15 is designed to have available. The 130W version can only pass 90W through, and if you use it with the XPS 15, you're likely to see slower battery charging and/or performance throttling due to the undersized power source.
The difference between the WD19 and WD19TB is that the former is regular USB-C, whereas the latter is Thunderbolt 3. This has two main implications. When used with the XPS 15 9570:
- The WD19 would be limited to dual displays up to 1920x1200 each or a single 2560x1600 display (or 4K but only at 30 Hz). The WD19TB can do dual displays up to 4K 60 Hz each and even some triple display setups because the fact that the WD19TB uses Thunderbolt 3 means it can tap into 4x more display bandwidth than the regular WD19.
- The WD19TB includes an "upstream" Thunderbolt 3 port if you want to connect another Thunderbolt peripheral, such as a Thunderbolt-based SSD or even an external GPU enclosure.
The DA300 works when connecting a single monitor, but it does not allow for 2 extended monitors simultaneously.. I've tried connecting my HDMI -> DVI cable to the HDMI port on my XPS and using the display port on the DA300; but only 1 monitor will work at any 1 time. Can you offer any advice to this?
If not, then I'll be forced to return that (If amazon allows it) and hopefully instead get the WD19 (180W) instead. The WD19 has 2 display ports & a HDMI. With this, I should be able to connect one of my monitors via the display port, and another through my HDMI-> DVI connection, correct? I don't intend to mirror any of my displays, I want both my connected monitors to be an extension.
