This projector could do that, it even has built-in speakers and can do 4K:

Acer H6816ABD (4K, 4000 lm, 1.5 - 1.66:1)

Too bad he is out of the question

Does anyone have a device recommendation: 4k beamer, suitable for daylight, bluetooth or wifi boxes must be connectable. Price up to max. 1300 fr.
Merci and greetings marcel

According to the manufacturer, the projector unfortunately has no WLAN and Bluetooth function and can therefore not be connected to other devices.
