Mini HDMI Display Port adaptors

Feb 17, 2025 Last reply: 1 year ago 34 Replies

I'm tring to get a decent monitor organised for a Rpi V5. It has two mini HDMI ports. I bought a mini HDMI to HDMI lead, that works with an old TV. I then bought a HDMI to Display Port adaptor, but got nothing on the known working Display Port monitor - this one.

It describes itself as 'The DisplayPort to HDMI 4K Adapter is designed for connecting DisplayPort1.1 and 1.2 equipped computer systems to HDMI equipped monitors, '



So probably the wrong thing anyway.



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


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

I have no idea what a "Rpi V5" is but thses converters are always directional in my experience.

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

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

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

Err, what was I saying about needing to be careful? Why are search engines *so* crap at matching stuff ...

Unless I'm miss reading it - That seems to be, what I already have.

Thanks anyway.

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:

It's almost as though Currys would prefer to sell you the wrong thing, rather than nothing!

Yes. Google strikes again

rPi5 is mini-HDMI, AIUI those are HDMI.

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 my first choice.

So I'm another vote for a different monitor.

DP => HDMI are two a penny, but I couldn't find any HDMI=> DP adapters in a casual search.. Again recommend an HDMI monitor. They are not the most expensive things in the world

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:

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

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

They are - however that is easy to fix, just a passive adaptor. You

*might* be able to find a suitable adaptor with micro HDMI, but it is not a show stopper if you can't

Indeed - as will be the case with any active adaptor that has electronics to power.

They ought to be a fairly light load, but only trying it will find out.

Seems rather an expensive way to do it - especially since if it is a native DP monitor, it is probably a fairly decent one.

I just use a lead with a mini HDMI plug at the R Pi 4 ( in my case) end and normal HDMI at the TV end.

I assume it will work on the R Pi 5, they both have two mini HDMI ports.

From memory, I bought the lead of Amazon but it may have been EBay.

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 prejudice, that my experience is that anything outside the norm can be problematic.

My latest failure is a NVME/USB enclosure, seems to work but at only 30 MB/s.

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.

Someone doesn't know what Display Port is...
