Problem with HDMI connection in Larkbox

Hi. I have purchased a CHUWI LarkBox.
I’m trying to connect HDMI to TV but any TVs in my home doesn’t recognize LarkBox that shows no signal.
I could successfully connect with my Mac. So I think TV is not the problem.

Is there any tips for fixing the problem? I would appreciate your help.


No support from CHUWI?

Same problem here: fine on monito but no signal on TV. Does anybody know how to get support from Chuwi?

No support from Chuwi at all. Defect products.

Similar issue.
The larkbox Pro works fine on a PC LCD, also works fine if I directly connect it to my 4K TV (Hisense 55H9F). However, running it through my receiver (Sony STR-DH590) it will not passthrough. I’ve tried new HDMI HDCP 2.3 cables and others. I’ve set the receivers FMT settings back and forth. Nothing. So it’s an incompatibility with chuwi/sony.
I can plug in an old crappy laptop and the passthrough works just fine. So for CHUWI, I will have to return as it’s not going to work as my HTPC.

I am experiencing the same connection issues what is the fix CHUWI

Bumping it up as I’m experiencing same problem…

Bump! The same problem! Where is CHUWI officials?

Hi. In 21-January-2021 I have purchased a CHUWI LarkBox .
I’m trying to connect HDMI to TV but any TVs in my home doesn’t recognize LarkBox that shows no signal.
I could successfully connect with my outher pc. So I think TV is not the problem.

Same here. No HDMI output no matter what. Tried removing the battery, removing the battery for several hours (held power button afterwards to drain each time), then reinstalling OS image (via keyboard only, which was tricky since there’s no display). Chuwi support has been slow, repetitive, and unhelpful.

HDMI Out monitor no signal. I tried a HDMI to USB converter. Everything works in the OBS Studio program. Larkbox no brick. :slight_smile: Unfortunately, I also need another computer on which OBS goes.

Hi guys, since CHUWI continues to ignore us without even trying to solve the problem or provide an answer why don’t we all join together and file a class action against him? It’s not fair to be treated like this after spending our money! They must pay!

The larkbox doesn’t work with any of my latest generation TVs or monitors, it only worked on a very old Saba LCD TV. If you write me a direct email I can send you a video
