YOUR CHOICE IN THREE BUDGET TIERS
A projector is a later comfort upgrade. Screen, blackout, sound and mounting are all part of the overall budget.
Our recommendations by features and use case, not a complete market test. The tiers apply within the category; daily deals can change the price order. Source check: 15.10.2026.
Why this choice? Our high-end choice for a deliberately planned home cinema with 4K UHD projection and an LED light source.
Before buying: Setup and blackout remain decisive. The projector alone doesn't make a complete home cinema.

Why this choice? Our mid-range choice if flexible placement matters more than a particularly compact build.
Before buying: Lamp technology: factor in follow-up costs and ventilation clearance; check distance with the calculator.

Before buying: Not a 4K device. Throw ratio 1.49–1.64: for 100 inches you need a lens distance of roughly 3.30–3.63 m.

On small screens the table can be moved sideways. The linked data sheets state the exact variant.
Our assessment: The 1.0–1.3 throw ratio allows a large picture at a shorter distance. The LED light source and placement are the main buying arguments.
The trade-off: Only ±5% vertical lens shift. Check the mounting height; digital keystone correction is no substitute for proper placement.
Information checked on 12.10.2026. Not our own product test.
Our assessment: Horizontal and vertical lens shift help when the optical axis isn't exactly centred. For this, the larger projection distance needs to fit the room.
The trade-off: The lamp is a later cost item. Screen, blackout, mount and sound belong in the budget too.

WILL THE HOME CINEMA FIT YOUR ROOM?
Enter the desired 16:9 image diagonal and the available distance from lens to screen.
Calculated from 16:9 image width × throw ratio. Rounding differences from manufacturer tables are possible. The result only checks the horizontal projection geometry, not brightness, mounting height, lens shift or ventilation clearance.
