Floor-rising tension screen recommendation for Valerion VisionMaster Pro 2 (Altbau apartment / No wall mounting)

Hey everyone,

I’m planning to get the **Valerion VisionMaster Pro 2**. Since I live in an old European building (*Altbau*) with delicate plaster walls, I strictly want to avoid wall or ceiling mounting.

I'm looking for a **motorized floor-rising tab-tension screen** (100" to 120").

My main priority is "**0%" laser speckle** (glittering) and no hotspotting, so I’m steering clear of ALR/CLR gray screens and looking at **Matt White (Cinema White)** surfaces right now.

Currently considering:

* **Vividstorm S White Cinema** * **NothingProjector Matte White** * **LeApex Soft Matte White**

Has anyone used the Valerion (or a similar RGB triple-laser standard throw) with one of these floor-rising matt white screens? Any experiences regarding motor noise, screen flatness (tension), or alternate recommendations for a speckle-free floor setup?

Thanks!
