Is 7,000 lumens enough for a lit room?

Yes. That output is well above typical home projectors and is meant for rooms with ambient light, such as auditoriums and classrooms.

Does it need a special screen?

No, but a matte white or gray screen suited to high-output projectors gives the best contrast. The 12V trigger can drive a motorized screen.

Only partly. It has vertical lens shift but no horizontal shift, so the projector should sit close to the screen's horizontal center.

Optoma rates it up to 10,000 hours in eco mode, far longer than a lamp and with no replacement needed.

Yes. It accepts 4K UHD signals at 3840x2160 and supports HDR, plus 3D playback.

HDMI, RS-232, USB-A, a 3.5mm audio out and a 12V trigger, with a remote included.
