Is the VisionMaster Pro2 a true 4K projector?

Yes. It outputs 3840x2160, so it accepts and displays native 4K content.

How far from the wall does it need to sit?

It is ultra-short throw, so it sits close to the wall, typically on a console beneath the screen. Exact distance depends on the screen size you want.

Do I need a special screen?

An ultra-short-throw or ambient-light-rejecting screen gives the best contrast and reduces speckle. A plain white wall works but looks flatter.

Does the laser need replacing?

No lamp swaps are needed. The laser light source is rated for years of normal viewing, though brightness slowly declines over its life.

Can I stream without a separate box?

It has Wi-Fi, so it can connect to your network for streaming apps and firmware updates. A separate streaming stick is still an option if you prefer one interface.

How does it compare with single-laser UST projectors?

Triple-laser light gives wider color coverage and steadier brightness than single-laser designs, at a higher cost. Single-laser models are simpler and cheaper but less vivid.
