So I was wondering if they could have swapped the output to the DisplayPort and
hence why I can't see anything
Now I've never come across DisplayPort before but I was thinking of giving one
of these boxes to our daughter and she was taking about running two displays (OU
work) so I would probably need an adaptor or lead of some sort anyway but I see
mention of passive and active solutions and would like some guidance as to what's what please?
From a physical POV, a short DisplayPort to HDMI female sounds the most flexible but an all-in-one lead would also work.
You can get dongles to convert DP->HDMI, you might need to be careful of what spec level of DP and HDMI, for HD probably not an issue, but for 4K it can be.

HDMI and Displayport are different protocols, kinda a bit like speaking English and French.
AIUI some Displayport outputs are bilingual and can speak HDMI, and so a passive dongle or cable is just to tell the port to switch to HDMI mode. However other DPs can't speak HDMI, and that's when you need an active translator.
In particular, USB-C only supports DP natively, so if you want HDMI you need a dongle with a USB-C plug configured to tell the laptop to emit DP and then a DP to HDMI converter chip.
Ok, that makes sense. So from the overview:
"HDMI x1 + DisplayPort x1 Support dual display
4K playback (Dual channel memory recommanded)"
I'm guessing that doesn't tell us enough about the capabilities of that particular DP?
From what has been said so far and after finding noting of use in what
they offer as a manual I did find on their site:
"DH110SE HDMI V1.4b and DP V 1.2" (In case that says anything) and ...
"The DisplayPort output can be converted to HDMI or DVI by an
additional, passive adapter cable. For example:
DELOCK 82590: 1 m, DisplayPort (male, 20p) to HDMI-A (male, 19p)
DELOCK 82435: 5 m, DisplayPort (male, 20p) to DVI-D (male, 24p)"
So the good news is it suggests a 'passive' solution.
"The integrated graphics automatically detects the connected display and
puts out the appropriate electric signal - either through DisplayPort (without an adapter) or HDMI/DVI (with an adapter).
I'm not sure I follow that bit? Ok, we probably know both ports would
output the right stuff to native matching monitors and that we could
probably use an adaptor in either to convert to a range of others and
would need an 'active' adaptor where the sense and output support aren't available?
"However, a monitor with a DisplayPort connector cannot be connected to
the HDMI port with a simple, passive adapter."
Ok, so it's covering at least one combo that can't be passive but is
that suggesting that all overs (minus VGA probably) can be done passive?
I have a PC (an i7 mini tower used as a TV box that might be replaced by
one of these Shuttle PC's) where I have used 'a cable' from the DVI out
port on the PC graphics card to the HDMI in socket on my Panasonic TV
... and that 'works' because (either) it's an 'active lead' or the TV is willing to take DVI over HDMI over a 'passive lead'?
I've ordered a couple of DP > HDMA F adaptors off Amazon for delivery
today and I have two HDMA monitors (TV's in this case) within reach of
two HDMA cables and the Shuttle so hope to see how it all goes later. ;-)

Not here, it's just saying the connector shapes.
A DP output can of course always do DP, so it tells us that.

Those are relatively old/lower end standards (~2014). You might have troubles with 4K, although it can probably be done with some limitations/tweaking.

Yes.

I think that bit is just saying that the port can do DP, HDMI and DVI and an appropriate cable or passive adapter will switch it into the right mode.

DP can sometimes output HDMI, but HDMI can never output DP.
So, as your
thing has 1x DP and 1x HDMI sockets, you could use two HDMI monitors but not two DP monitors. If you wanted to have two DP monitors you'd need an active converter from HDMI to DP.
(The situation with DVI is similar: DVI ports can't output HDMI signals, but some HDMI ports can switch into a mode compatible with DVI.
So if a DP
output can do HDMI, it may also do that in a way that's suitable for DVI
with a passive cable)

Yes, I think so. Likely the TV sees the DVI signal and knows what to do
with it. I doubt there is any conversion going on.

I think that should probably work.
