You should be able to, but it is something that doesn't always work for
reasons I do not have access to.

I'd be tempted to save a lot of hassle and get an HDMI equipped monitor

yes you need to search for "mini hdmi source" to "displayport sink" and
check the results haven't reversed what you actually searched for.

So can I get from HDMI output from a Rpi, to Display Port monitor?

Yes, but you need an active cable (or adapter) not passive
e.g

<https://www.currys.co.uk/products/esl-gaming-mini-displayport-to-hdmi-cable-3-m-10209865.html>

I'd stick with a cable, rather than adapter or they're more likely to
fall/pull out.

Display port to HDMI is easy, however the other direction is not as easy...

For DP to HDMI there are two routes - passive cable - works when the DP
end can do the required conversion (usually flagged as DP++), and active conversion extra box of tricks does it externally.

To go the other way you will need an active converter of some kind. Note
I have not tried these, so can't say if they are any good, but perhaps:

RPi5 is *micro* HDMI. Micro HDMI to HDMI is just a mechanical adapter. Mini-HDMI is (yet) another connector, as found on the Pi Zero.

I'd favour a known-good active adapter over one that doesn't work very well
but has the right plug on it.

I bought a micro HDMI to HDMI adapter t'other day, works fine on a Pi 4: https://www.amazon.co.uk/dp/B007NVZA72

And they appear to need USB, presumably for power. I have had problems/instability powering stuff off my rPi5 USB, so it wouldn't be

Yes it's just for power. If you're worried about that power them from a separate power supply.

So I'm another vote for a different monitor.

If such is available, that would avoid active adapter shenanigans.

Yes, I know, it seems cheaper to use an adapter that should work, but...
Maybe it doesn't, or maybe it has performance problems, or maybe it
crashes occasionally, or maybe it needs another power supply.

If it doesn't work, you are left with junk. If you buy a standard
screen, you have a spare screen to use somewhere else.

I don't want to put him off, because I don't know enough, just a

Video signal converters work well in my experience but they are
directional and whatever you search for the search engine will throw up
both directions. I have VGA to HDMI (has a USB plug for power),
Displayport to HDMI and vice versa (one way was expensive because it
needed electronics) and DVI to HDMI plus, I think, DVI to Displayport.

Displayport was all the rage when I bought my monitors, my latest Dell is
HDMI only and I have a USB/HDMI switch.

Yup all that is fine, and will work. The problem comes when there is no

The R Pi has a (mini) HDMI output ( actually 2 of them).

Display Port adapters typically have a DP input and an HDMI output - to
allow, for example, a laptop with a DP output to use an HDMI display.

The adapters don’t work ‘in reverse’, at least in general.

DisplayPort is a packetised protocol and is similar to Ethernet. However
most forms of DP sources will detect an HDMI sink where the signals are
mapped from DP connector pins to HDMI connector pins.

In this case the DP source outputs HDMI signals and not DP signals.

A DP monitor requires a DP source, and the only way of driving a DP
monitor with HDMI signals is with an active adaptor that produces the
clocks and TMDS data.

The safest solution is to get a monitor with an HDMI input.

most forms of DP sources will detect an HDMI sink where the signals are mapped from DP connector pins to HDMI connector pins.

In this case the DP source outputs HDMI signals and not DP signals.

A DP monitor requires a DP source, and the only way of driving a DP
monitor with HDMI signals is with an active adaptor that produces the
clocks and TMDS data.

Nice explanation :)

The safest solution is to get a monitor with an HDMI input.

Or DVI - which is a simple passive adaptor to HDMI (both ways)

I see many ex-office monitors in Charity shops featuring all sorts of connectors. They are often less than a fiver.

DVI and HDMI are pretty much interchangeable though worth remembering
that a compliant DVI doesn't carry audio. But some aren't and do
actually carry audio.

The monitor, by default, is used with my desktop. What I have done, is
install RealVNC on the desktop, which now enables me to take control of
the Rpi, and it's display, on the desktop.

yup, and moreover there are also HDCP issues if attempting to display TV
style video from HDMI, which also the monitor may or may not support -
though probably not an issue with the OP's Raspberry Pi usage.

Usually the prices here are too high. I use the site
for an "existence" check, to see if an item is made.

"Active HDMI to DisplayPort 1.2"

https://www.startech.com/en-ca/display-video-adapters/128-hdmi-displayport

Chipset ID Lontium - LT6711A

*******

This looks like a cheap one. Helpfully, they labeled "source" and "display"
so you know which direction of conversion it supports.

Active HDMI to DisplayPort Adapter (4K@60Hz),
Uni-Directional HDMI Source to Display Port Converter Cable HDMI Male to DP Female

https://www.amazon.co.uk/HDMI-Adapter-Uni-Directional-Male-Female-Grey/dp/B0DHXFKZGM

There are some Club3D branded ones, and that "branding" (which used to be
a video card company at one time), makes a few different models. Some with better specs than others.

The USB +5V supply is "optional". It can be thrown in as a cable, when
the chipset manufacturer refuses to bound power consumption, and the
USB cable is the "auxiliary supply" in case it does not work. By using
the USB cable, it should stop drawing +5V from the HDMI source device,
and instead draw it from whatever provides the USB power.

Generally speaking, the higher the resolution requested, the warmer it is
going to get. Run at 1920x1080 @ 60FPS, it's possible you could leave the
USB cable dangling. The display resolution and refresh determines the datarate on the cable.

The EDID from the monitor, should flow back to the source device,
and the source device defines the resolution and refresh. I use several adapters here for monitors, but the type you are getting, I have
zero stock of those. If for any reason, the EDID signal did not
go back from the monitor to the source device, the source device
will select 1024x768. If circles look like ellipses or such,
then it's an EDID issue. An EDID dumper program can be used
to see what resolutions the monitor supports (the "native" res
giving the best picture).

That is a very sane solution.

I have loads of pi's and no screens on ANY of them. And no GUIS either...

I've got three LCD monitors sitting on the floor here because they are
too good to skip.

One flickers a bit. None are HDMI - only VGA

They may end up trashed if I spring clean...

You can get a NEW 22" full HD monitor for less than £70.

Less than £60 from Argos.

The DVI standard doesn't but most DVI ports are driven by HDMI
compatible ICs, such they inadvertently do carry video. However it's not
a certainty.

I use a USB HDMI (input) adapter and the default camera "app" on the desktop

A small USB keyboard connected to the Pi if necessary. Usually only for
initial setup, or if I've B*lloxed it up somehow.

Ive got a huge HDMI screen for another project that gets used as a
monitor for the pi if i have as you say B*lloxed it up somehow.

Otherwise remote access keeps the box count down.

I tried to get pis up without an HDMI screen and mostly it works, but
when it doesnt there is no better alternative really.
