I have bought Philips GoPix 1 pocket projector. If I connect to computer via HDMI that works fine. If I connect it to my Honor Magic 4 Lite or Huawei Nova 9 SE phones via USB-C to USB-C, the projector says "No imput source".

In the "Use USB To" menu is no option to project view and if I choose any other option, it always back to "Reverse Charge".

I think I am missing something in the phone options. Could you help me to properly setup phone to project view?
 
You can only connect a phone that supports USB-C alt mode for display output. Basically out of all modern phones it's only the ones from Samsung that support Dex, and maybe few niche "gaming" phones.
Xiaomi's desktop mode never came to be. Huawei had something in the works, but I haven't yet had a chance to try it with my own hands.
Google promised native "desktop mode", but so far it's only available if you root a Pixel 8.

According to specs of your projector it might have support for MHL alt mode, which means you can also try an older phone with MHL. Though it may not work over Type-C cable and require an additional micro-USB to HDMI cable/dongle (as far as I remember there were quite a few phones and tablets with MHL back in a day, including my 'ole shitty Chinese THL phone).

But your best bet is Dex. Even something as old as Galaxy S9 should do.
