LattePanda Alpha USB-C to HDMI Display issue


#1

Hi there,

This is not a Hackintosh issue but I’d like to ask fellow users of LP Alpha if they’re having the same issue.
I have USB-C hubs that have several USB-A ports, an HDMI port, and a power input USB-C port.
So, basically, if you just connect a single wire(USB-C), the powering and displaying in addition to transferring data are all enabled at once.

The issues I’m having,
(1) Flickering pixels at random location
(2) Jiggling of the bottom half of the screen

I tested on two monitors(4k, FHD) and two USB-C hubs(different models).
I also observed the above problems in the boot logo screen, so I think it’s a hardware problem.

I’m wondering it’s just mine that is faulty or it’s an inherent problem by mal-design.

Thanks.

Maybe just use the HDMI port? It just works for my setup.

Sounds like a dodgy USB c port

It was some kind of a hardware issue. I sent my LPA for RMA and got a replacement unit. Everything works fine.

Connecting my LP Alpha via the USB C port to a screen works under mac mojave when the LP alpha starts up, but as soon as the login screen appears, it seems to crash the Panda, at least the screen goes blank. HDMI works fine (with the original power supply). I dont think its a power supply issue as the USB C on this screen can charge a macbookpro whilst running.
Anyone have any suggestions what I can do about this?

It’s a bit late reply but hopes this helps.
Try running different OSes to check the hardware is sane.
Especially Windows since it’s kind of an official OS that LattePanda is advertising.

My LP experienced the same problem in every OS(Windows, macOS, Linux)
