— Projector Throw · Ultra-short-throw laser TV
Hisense PX3-PRO throw distance & placement
Problem. A 100-inch image from an ultra-short-throw laser TV lives or dies on centimetres, not metres: the Hisense PX3-PRO has to sit almost flush against the wall below the screen, so the placement question is cabinet clearance and screen alignment rather than a ceiling mount position. This preset opens the calculator on the PX3-PRO's fixed 0.22:1 throw ratio so that geometry is visible before any furniture or wall-unit decision is made.
Answer. At a 100-inch 16:9 screen, the Hisense PX3-PRO sits 0.49-0.49 m from the wall, which the calculator reads as the distance from the projector's lens to the screen surface, not the depth of a media console. That places the unit essentially on a low cabinet directly beneath the screen, so the room decision becomes cabinet height and screen-wall flatness rather than ceiling throw or zoom range.
02 / In depth
How this preset reads — the engineering view.
The PX3-PRO uses a fixed ust (ultra-short-throw) lens with a 0.22:1 ratio, so at a 100-inch 16:9 image the calculator returns a 0.49-0.49 m throw distance. There is no zoom to adjust that number: moving the cabinet a few centimetres closer or further changes the image size directly, which is why UST placement is measured in centimetres rather than the metres typical of ceiling-mounted projectors.
3000 lumens is a modest output for this native 3840x2160 panel, so the PX3-PRO reads best in a room where ambient light at the screen can be controlled, not a bright daytime space with windows facing the screen. The tri-laser-rgb light source gives wide, stable colour coverage at that lumen level, which suits an evening living-room or media-room setup more than a naturally lit family room used through the day.
From here, drag the screen-size slider to see throw distance move in step with image size, since the 0.22:1 ratio scales linearly with any screen width. Because this is a UST cabinet rather than a ceiling mount, also check the physical cabinet depth against available console space, and treat an ambient-light-rejecting (ALR) screen as a paired decision alongside the throw number, not an afterthought.
The calculator does not decide screen gain, how much ambient light a given ALR screen actually rejects, cabinet or wall-unit mounting details, or audio system pairing. The PX3-PRO also does not carry an interchangeable lens, so there is no lens-selection step to reconcile here, unlike large-venue projectors where the exact lens changes the throw math.
What this preset deliberately does not solve
- The 0.22:1 ratio is fixed: there is no zoom or lens-shift to correct minor placement errors, so cabinet position must be accurate before installation.
- 3000 lumens against native 4K resolution means picture quality is more ambient-light-sensitive than higher-lumen laser TVs in the same category.
- Throw distance alone does not confirm image quality: screen material, ALR performance and room light control affect the result as much as geometry.
How this preset differs from its siblings
Ultra-short-throw laser TVs vary meaningfully in throw ratio, lumen output and native resolution, and those differences change both the cabinet-to-wall distance and how forgiving the unit is of ambient light. The PX3-PRO's 0.22:1 ratio and 3000-lumen tri-laser-rgb engine define a specific placement and viewing-condition profile at native 3840x2160 that is not identical to other UST laser TVs in the catalogue, which is why this model has its own preset rather than sharing the general UST living-room entry.
