Why the Horizon 20 Pro is our house-front pick

A house front is the hardest common mapping surface. It's big, it competes with porch lights and streetlights, and the projector has to sit out in the yard. Based on XGIMI's published specifications, the Horizon 20 Pro covers the three things that matter most for that job. It is rated at 4,100 ISO lumens (ISO 21118, measured much like ANSI lumens). Its 1.2–1.5:1 optical zoom lets you fill the surface without finding one exact spot on the lawn. And its lens shift, which XGIMI lists as ±120% vertical and ±45% horizontal, lets it sit low or off to one side of the driveway without digital keystone, which throws away pixels and light.

It also runs Google TV, which matters if you map from a phone: a Google TV projector can run receiver apps from the Play Store, so the phone can connect over Wi-Fi instead of trailing an HDMI cable across the lawn. Its two HDMI inputs cover the wired route.

We have not tested a Horizon 20 Pro ourselves; everything here comes from XGIMI's spec sheet. One detail worth knowing: XGIMI lists 3840 × 2160 on a 0.47-inch DMD, which means 4K by pixel shifting rather than a native 4K chip. That's fine for house mapping, where brightness and contrast matter far more than resolution at street distance.

Is it bright enough for your house?

Projector light spreads across the image, so the answer depends on what you are lighting. At 4,100 ISO lumens, the Horizon 20 Pro is comfortable on a garage door and at the low end of the range for a whole house front. Expect a good result on a light-colored, single-story front with the porch lights off. Expect a disappointing one if you stretch it across dark brick or two stories: brick absorbs light, and a second story roughly doubles the area, which halves the light reaching every square foot.

Rough targets after full darkness:

• Windows projected from inside, and porch props: about 300+ ANSI lumens (1,000+ if the window faces a bright street or you start at dusk)
• Garage door or a single outside wall: about 3,000+
• Pale single-story house front: 4,000–5,000+
• Dark brick or a two-story front: more than one 4,000-lumen projector can convincingly light

When even the Horizon 20 Pro isn't enough

If you need the whole surface lit, step up rather than stretch. The Horizon 20 Max is rated at 5,700 ISO lumens with the same 1.2–1.5:1 lens, lens shift and 40–300-inch image range, so every distance in this guide still applies. Beyond that, two projectors each covering a section, or a rented 5,000+ lumen installation projector, are the realistic routes for a large facade. Two projectors also mean twice the alignment, power and weather protection.

To keep a single Horizon 20 Pro, change the plan to suit the house:

• Dark brick or stone: map the brightest section, such as the garage door, the area around the front door, or a pale gable, and leave the rest dark.
• Two stories: map one story or one vertical section rather than the whole front.
• A front wider than about 22 ft (6.6 m): that is past the largest image XGIMI lists (300 inches diagonal), so one projector can't cover it at any brightness.

Throw distance: how far back it sits

Throw distance is image width × throw ratio, measured from the lens to the wall. With a 1.2–1.5:1 zoom, the Horizon 20 Pro needs 1.2 to 1.5 feet of distance for every foot of image width. For tall surfaces such as a single garage door, size the image to the height: a 16:9 picture is only 56% as tall as it is wide, and you mask off the sides in the mapping app.

Add room behind the lens for the projector, cables and stand, and keep it off the sidewalk and out of the street. Our throw-distance calculator does the same math for any projector, and the throw-distance guide has a chart for windows, walls and props. For the Horizon 20 Pro:

Power: plan the cord before the projector

The Horizon 20 Pro runs on mains power only; XGIMI lists consumption of up to 230 W (280 W for the Max). That is roughly 2 amps at 120 V, so cord capacity isn't the problem. Safety is:

• Use an outdoor-rated extension cord. In the US, the jacket rating includes a W, such as SJTW.
• Plug into a GFCI-protected outlet.
• Keep plugs and connections off wet ground, ideally inside a covered connection box.
• Route cords where nobody walks, or cover the crossing with a cable protector.
• Keep the phone charging too, through a USB-C hub with power pass-through or the charging port on Apple's Lightning adapter. Our cables and adapters guide covers which phones can output video.

Weather, wind and condensation

XGIMI lists an operating range of 32–104°F (0–40°C) and no water-resistance rating, so treat the Horizon 20 Pro as indoor electronics that you use outside on dry nights. Halloween evenings are usually inside that range; plenty of December nights are not.

Shelter it from rain, sprinklers and dew with an open-sided cover that leaves the vents clear, keep it off damp ground, and never run it in a sealed box: a projector that can't exhaust heat will throttle or shut down. Bring it inside afterwards, and let a cold projector warm up before you power it on, because condensation forms when cold electronics meet warm, humid air.

At 4.9 kg (10.8 lb), it is top-heavy on a lightweight photo tripod in a breeze. Use a sturdy table or platform, or a stand rated well above its weight. XGIMI's Floor Stand Ultra attaches with a standard 1/4-inch screw, lists the Horizon 20 series as compatible, and is rated to 10 kg. Whatever you use, weigh it down and mark its feet so it goes back in the same place tomorrow.

Placement checklist for show night

Set up before dusk, but only judge brightness once it is fully dark: an image that looks weak at twilight can look strong an hour later.

• Place and focus the projector, then switch off automatic keystone and focus adjustments in its settings. XGIMI advertises uninterrupted auto keystone, which can reshape the image under your mapped shapes.
• Use optical zoom and lens shift to land the image, not digital keystone.
• Mask light away from the road and from neighbors' windows.
• Turn off porch and garage lights that fall on the mapped surface.
• Watch the whole loop from the sidewalk, where the display is actually seen.

Windows and props: a small projector's job

Not every part of a house display needs 4,000 lumens. A window projected from inside the house needs about 300+ ANSI lumens in a dark room, and the projector stays warm and dry. The Nebula Capsule 3 Laser (300 ANSI lumens, 1.2:1 throw, about 2.5 hours of battery, tripod thread) is the one we use, and Lazy Lighting's Halloween setup guide covers hanging the fabric and mapping the window. A bright projector on the garage door plus a small one in an upstairs window is a common, effective combination.
