Hi Community 
I have the S6 ‘triple screen’ (it is 2 screens that flip out either side of the laptop screen.
They are a ‘portable’ screen in that they fold up and pack away for travel, and IMPORTANTLY, run off USB-C without separate power.
My Lattitude 7440 laptop runs them both well from the 2x USB-C ports, but, you need 3x USB-C in order to power the laptop!
I have tried the screens on other laptops and docks, and the results are inconsistent, so hoping someone may have direct experience or tips.
Thanks in advance
Links in case they are of interest
Ok, here is link to the product. Two thirds of the way down the screen is a fairly descriptive graphic

your first link seems to have become subject to link rot
when you connect them, do you get any signs of life from the monitor (i.e. is the laptop providing enough power?)
also, what os are you running? windows or linux?
im presuming that the monitors are dp alt mode instead of displaylink given that they use type-c and mention displayport and full-function interfaces in the second link
if you are on linux, have you ever seen graphical artifacts such as coloured (ive heard of or personally experienced pink, green, white, white/grey bars, and black, covering various areas of the screen) flashes on the main screen of your laptop? im guessing you probably have since this seems to be a specific problem with the 7040 series. if so, do you know what the resolution and refresh rates of the monitors are? (note, graphical corruption such as technicolour static, possibly combined with a tiled translation of the image on other hi-res/high refresh rate displays also counts for this one. if you get such artifacts on your external monitors, try turning down the resolution and/or refresh rate to see if that helps - its not a solution but it is a workaround and helps isolate the issue)
Also, what ports on the laptop are you connecting the monitors to? Not all can provide display output.
Thank you COBSOD
I have not yet bought my Framework laptop. I have asked this question in advance of taking the risk.
Yes, it appears the screens I have are now superseded. But, the key point is they work directly in the 2x USB-C ports on a HP laptop and a Surface 8 Pro, but not via any docks we have tried yet.
The challenge I have is that the reference is ‘fully featured USB-C’. However, the docks we tried say that they are this, but then do not run the screens. I sense that it is the single USB-C connection from laptop to dock, that does not then allow the 2x USB-C screens to run.
Maybe I just have to bite the bullet and buy the framework and find out, or I will take the safe route and buy a HP or something ¯\(ツ)/¯

yep, i suspect that would be the case
in theory, it would be possible to hack together a dock that connects over one type c port and can run multiple monitors (namely, by integrating a displayport multi-stream transport hub into the dock and then reinjecting its signal into the type c ports), but its such a niche use-case that its more practical for dock manufacturers to just provide more traditional video outputs (usually hdmi, possibly displayport, and possibly something like dvi or vga) on the dock itself. i wouldnt say its worth the effort for the amount of custom design you would have to do.
i reckon it would work off the type c ports in the framework 16 directly (since iirc three of them can output video, not counting the one on the dgpu) - but you have two potential issues
1 is the igpu lacking the bandwidth, which seems to be exacerbated by the linux drivers (although its not a framework specific thing - its something that has been an issue with mesa+amdgpu for a while now on the 7040 igpu, and i dont think its a thing on the igpu on the higher-end cpu available for the framework if you shell out the extra 200 quid or whatever it was, but im not certain since i only have the worse cpu to test) - if you get the dgpu as well you could likely use the output on there to drive one of the monitors. ive personally once ran two 2k 144hz monitors in addition to the internal monitor off my laptop (one external monitor in the dgpu output), and the only issue i noticed at the time was that the 2k monitor running off the igpu seemed to have a lower refresh rate than it should (mouse cursor had jittery movement like it was 60hz), but that was ages ago before the bug in mesa that caused graphical glitching was first introduced. i reckon if you stick to windows you would be absolutely fine, and on linux you could in theory install an old distribution (iirc early fedora 40 didnt have this problem, although finding the old packages would likely involve compiling them yourself) and pin mesa at whatever version was before the glitching became a thing.
2 is getting power to them, although they say that they can run off a type a to type c cable plugged into the laptop (one for each monitor i guess) so i imagine they dont draw that much and you would be able to get by even on the fw16 (which has some rather low-amperage fuses on the usb ports from what ive read, but given that i know from accidentally blowing one that they do 3 ports each (1 fuse per side of the laptop) then you would probably still be fine. even if you trip them, they self-reset after a while of leaving the laptop off and unplugged so you dont have to worry about killing the laptop)
tldr: i reckon it would be possible to make them work, especially if you got the better cpu and/or the dgpu (or just stuck to windows)
Dual screens with built in mst are apparently a thing, this one probably isn’t one of them though.
