USB-C is not working with external monitors

Hello everyone! I recently purchased the Chuwi Minibook X N100 and received it yesterday.
I’m attempting to connect my new laptop to my Dell monitor (Dell P3222QE) using the USB-C port,
but unfortunately, nothing is appearing on the screen. I keep receiving the message ‘No USB-C signal from your device.’

I’ve tried both USB-C ports on the Chuwi, but nothing happens.
The only functionality I get is with the mouse and keyboard connected to the Dell monitor as a hub.

Could you please advise if this is normal, or if there’s something specific I should do?
Thank you in advance!"

Hello,
Have you checked if the cable you are using is compatible? Is it a cable that has all lines, for Video transmission?

Not all USB-C cables are the same. Some of them, most of those provided with smartphones, etc, are only data and power.

Have you tried another monitor or a projector? I have used the USB type C ports to connect an adapter with USB type A ports, ethernet port and HDMI output to connect via HDMI cable a projector. In this case it worked without issues.

Hi

I am currently able to connect my work laptop to my Dell monitor using a USB-C to USC-B connection.
This allows me to display in full 4K resolution on the Dell monitor. However, when I attempt the same setup with my Chuwi Minibook X, I encounter issues. The only successful connection involves using a hub through the USB-C port on the Chuwi and then connecting to the Dell monitor via HDMI. Unfortunately, this method limits the display resolution to 1920x1200 pixels on the monitor.

Or chuwi has no DisplayPort Alt Mode (DP Alt Mode) that allows a USB-C equipped computer to connect directly to a display or monitor?

The usb port closest to the back is for data and Chuwi 12 volts charging charging. Connecting my 4K screen that can deliver power over USB C as well to the other USB C port of the Minibook works fine. Both 4K resolution and battery charging. Tested with Windows 11 and Ubuntu 24.04. It could be an incompatibility issue while by using the hub you get display.

Hello again,
This is possible because these adapters have all the wires needed to provided data and video and convert the signal to HDMI.

From my understanding, you are trying to connect a USB-C monitor and for this, you need a cable compatible.

Is your USB-C port designed for video output (DisplayPort Alternate Mode or Thunderbolt 3)? Consult your device’s manual or manufacturer’s website.

if after all the help that these nice guys here are offering is not solved, just give me an @, so i will ask tech after holidays(we come back on 19th). But i have checked and Minibook USB C has full functions so it should work.

I just received a Chuwi MiniBook X with the N100 processor, and it does not connect to my Dell UltraSharp 24, U2419HC monitor(s). I have an Acer SF314-42 which connects with it/them perfectly. I’ve tried the Win11 the MiniBook X came with as well as linux (mint 22 and fedora 40), to no avail. Everything else, so far, seems to be working well.

Any ideas?

It’s quite a coincidence that two different Dell monitors don’t work. That could be a protocol negotiation issue.

It seems there is a firmware upgrade for your monitor. You could check the release notes to see if they mention such an issue. You may decide to update your monitor.

In addition, looking at the manual that comes with your monitor there are a number of settings related to USB c connectivity. You could try to toggle them back and forth, one by one.

Else you could try a USB c to HDMI cable. Pay attention to the desired resolution and refresh rate when purchasing such a cable. The Intel N100 can handle up to 4K @ 60 Hertz.

Yes, I know, it should all work out of the box…

Cheers, Jaap

There is nothing wrong with the monitors. I’m using them now with the Acer.

As I see it, it is either the case that the MiniBook is not configured correctly in some way, or it does not support these monitors somehow, or it is defective.

Where did I write there is something wrong with your monitor? Don’t ask for ideas if you already made up your mind.

Here:

I am open to any ideas, I will look at monitor firmware, but as the monitors are working with other computers (the Acer at this moment), it seems likely they are not the problem. I’m hoping it is some issue with configuration of the Minibook X or a protocol they do not support (which might be addressed by a port converter, etc.). I’m looking for solutions other than the Minibook X being defective. It seems fine otherwise (charges from the monitor’s USB-C, sees devices plugged in to the monitor’s USB-A ports, etc.).

Update:
I just checked and the monitor says it has firmware revision M3T107, and checking with Dell, that is the current/latest for that model, Dell U2419HC.

Agree, while I haven’t found any means of configuring the minibook, I suggested to look at the monitor settings, as well as to use another cable.

Both ideas are about issues with possible protocol negotiation between two devices. That is not uncommon in the industry. Per company, interpretation of standards may differ.

I work with a similar monitor, but from another brand. That one works fine with both the minibook and a Lenovo laptop. Like yours, my monitor also delivers power over USB to the laptop. Finally, I tested with Windows 11, Ubuntu 22.04 and Fedora Core 40.

Maybe I’m just lucky. :wink:
