Question about Lenco LPJ-500

No

only use DVDs and USB stick with mp4 films/ have no tv stick, no Netflix MfG cubu

usb stick works for mp4, everything else I don't know, don't have a TV stick, watch everything via internet and LED screen, only need projector for DVDs. Movies, because no Netflix

The projector is crap. Poor lighting and rotten resolution. The only advantage is the CD player and Bluetooth sound on an external box.
But if you've got a computer with HDMI, you can connect it to Netflix.

No, that does not work

I don't remember that too long ago. But the projector is very weak and therefore no good. No lighting
