XGIMI Horizon Ultra throw distance & placement
Problem. The XGIMI Horizon Ultra is a fixed-lens home cinema projector, so there is no zoom ring to absorb a mismeasured room - the placement distance has to be right before the unit is mounted or shelved. At a 120-inch 16:9 image this preset answers the one question that actually matters: how far back does the projector need to sit.
Answer. At a 120-inch 16:9 screen (2.66 m wide), the Horizon Ultra's fixed 1.2:1 throw ratio puts the projector at 3.19 m from the screen. That is a single, non-adjustable number - the room needs a shelf, ceiling point or rear surface at (or very close to) 3.19 m, not a range either side of it.

How this preset reads — the engineering view.
The Horizon Ultra uses a fixed lens at a 1.2:1 throw ratio, not a zoom lens. That means throw distance and screen size are locked to each other in a straight line: change one and the other must follow. For the 120-inch 16:9 screen this preset opens on, that works out to 3.19 m from lens to screen - plan the room around that distance rather than expecting the projector to adjust to the room.
Rated at 2300 lumens with a native 3840x2160 panel and an LED-laser-hybrid light source, the Horizon Ultra is built for a room where ambient light can be brought down - evening viewing, blackout curtains, or a dedicated media room - rather than a bright daytime lounge. It suits a 120-inch (or similarly sized) matte or ALR screen where the image doesn't have to fight strong daylight.
From here, drag the screen-size control in the calculator and watch the throw distance move in lockstep with it - because the lens is fixed, there is no separate zoom adjustment to unlock a range of distances at one screen size. Use this to find the one screen size that matches the distance actually available in your room, rather than the other way round.
The calculator settles throw distance and screen geometry only. It does not decide screen gain or material, how well the room rejects ambient light, ceiling or shelf mounting hardware, which lens ships on interchangeable-lens projector bodies (not applicable here, since this unit's lens is fixed), or the audio setup around the picture.
What this preset deliberately does not solve
- The 1.2:1 throw ratio is fixed - there is no zoom to correct for a mismeasured room; the 3.19 m figure is the placement distance, not a range.
- 2300 lumens is a bright-enough figure for controlled or evening light, not a substitute for a fully blacked-out room at very large screen sizes.
- Native 3840x2160 resolution and the LED-laser-hybrid light source are panel and illumination specs; they don't change the throw geometry calculated here.
How this preset differs from its siblings
Most other home cinema projectors on this calculator carry a zoom lens with a throw-ratio range, so the same screen size can be hit from several distances. The Horizon Ultra's fixed 1.2:1 lens removes that latitude - one screen size maps to exactly one throw distance, which changes the planning conversation from 'where roughly can I place it' to 'is there a surface at precisely 3.19 m'. That single-number constraint is specific enough to this model to warrant its own preset rather than folding it into a generic home-cinema entry.
