Can't update Dreamcolor Z27x firmware

[Kilrag]

Hello everyone,

I have an issue with a Dreamcolor Z27x (this one https://support.hp.com/us-en/product/hp-dreamcolor-z27x-studio-display/6644016/model/6644017?sku=D7R... ). The firmware is in Z7X220 and I need to upgrade it to be able to calibrate it with an xrite pro.

I did exactly what is write in the user guide :

- I copyed the .tar.gz file at the root of an empty and formated fat32 USB stick (tried in fat and NTFS too)

- Enabled the internal processor of the monitor

- Waited few minutes

- Inserted the usb stick into the monitor (the usb 2.0 dreamcolor ports)

But then, nothing happens.

Already tried another USB stick, tried a reset factory too.

In the menu i saw it is possible to update the monitor via network, but nothing is write about it in the user guide.

Any solutions are welcome,
Thanks helping me.

Hello and thanks for your help,

Indeed this is the driver I want to install !

I did everyting until step 4 : Insert the USB flash drive with the latest firmware file into one of the dedicated USB DreamColor ports. The Z27x will automatically detect the firmware file and display on-screen instructions on how to install the firmware.

But the Z27x does not detect the firmware file....

ok, but you don't tell me
you mention having a previous version unless I'm mistaken
it is advisable to make the update that I gave, before going to the last one ..
there too it does not work?

[Kilrag]

Sorry if I was not clear 🙂

My monitor is in 220 version. I tried to update to 230; 240; 250 but none of them are working. I don't have any "display on screen instructions" as I am supposed to have when I insert the USB flash drive.

[Prométhée]

No problem
So, from what I saw, you did everything right
there is nothing more in the manual!

User Guide

you have tried all usb ports?

[edit]

You may be better at English than I am
I just read something that might make the difference, but I'm not sure
in the update document it is written:
This firmware update only functions correctly with the HP DreamColor Z27x Professional Display.

except you indicate to have the version
HP DreamColor Z27x Studio Display
there is another vesrion which is the pro

Sorry if that's not it then I can't see what might be wrong

[Kilrag]

Yes I tried all usb ports 😞

Strange fact about the "studio" and "professional", different names but both names are used in the same product page (and I see no difference between them). I think it is probably a commercial different name (maybe the name is not the same in different countries) but I think it's the same product.

Indeed
so unfortunately in this case I am of no help
I have covered the question I think
apart from rechecking with a small usb key by following step by step what is indicated, I have no other ideas
