Browse categoriesBefore choosing a model
Choose image width, then multiply it by the 1.5–1.7 throw ratio to estimate lens distance. Add clearance for the projector body and connected leads.
Use large slide text and a dimmed room. A 4K source does not increase the native panel resolution, and no screen or mounting bracket is included.
What distance makes a 2 m-wide image?
About 3–3.4 m from lens to screen, followed by manual focus adjustment. Leave extra space behind the projector for its body and leads.
Is the lumen figure independently tested?
No. It is a fictional specification for this example catalog. Actual room suitability has not been measured or certified.
