Living room walls actually have plenty of idle time to spare. Place the HORIZON 20 Pro and turn it on.
That alone creates a sensation where the imagery smoothly spills past the boundaries of a traditional television. Whether it’s a lazy afternoon where closing the curtains sparks a family debate, or a movie night, you can easily lean into a “lifestyle with a large screen” without drastically altering your room’s layout.
A design that isn’t fussy about placement helps alleviate much of the usual hassle associated with projectors.

Design and Placement


The strength of this model is its ease of placement.
It supports “lens shift,” which allows you to move only the projected image vertically and horizontally without moving the main unit itself. Because the vertical adjustment range is wide and the horizontal range is also quite broad, it is easy to align the center of the screen even when placed on a shelf near a wall. Furthermore, “optical zoom” allows you to change the screen size without sacrificing image quality, making it easy to adapt to the depth of your room.
It weighs 4.9kg. While somewhat heavy for carrying around, it sits securely and stably as a result. The primary expectation is for stationary use.
Ms. GadgetIs it okay if the center is misaligned?
Mr. GadgetYes. First align the center using the lens shift, and keep keystone correction to a minimum to help maintain image clarity.
| Pros | Cons |
|---|---|
| Allows large adjustments to screen position without moving the unit (Lens Shift) Can resize while maintaining image quality (Optical Zoom) Auto keystone correction and AF provide fast startup-to-display times | At 4.9kg, it is unsuitable for portability HDMI has only 2 ports, requiring switching if you have many devices |
Picture Quality and Brightness (Including Color and Contrast)


Brightness is rated at 4,100 ISO lumens. It is at a level where it is “clearly visible” even in a daytime living room. In locations exposed to direct sunlight, it naturally looks washed out, but drawing the curtains slightly makes it dramatically easier to view. At night or under blackout curtains, colors emerge vividly, resulting in crisp and dynamic imagery.
Furthermore, because the reproducible color gamut is wide (BT.2020 110%), the vibrant colors of anime and games are rendered beautifully. In addition, a mechanism that adjusts light output according to the scene (DBLE) is effective, allowing blacks in dark scenes to sink deeply while bright scenes appear luminous. In short, it delivers imagery with easily perceptible light-and-dark contrast.
| Pros | Cons |
|---|---|
| Brightness makes subtitles easy to read even in daytime rooms Wide color expression makes anime and games look vivid Deep blacks in dark scenes make movies easy to watch | Not an ultra-short-throw projector |
Sound Quality (Built-in + eARC)
The built-in speakers (Harman/Kardon 12W x 2) feature dialogue in news and anime that is very clear and easy to hear. For everyday use, this alone is more than sufficient. Because it supports eARC, you can easily upgrade your audio using a single HDMI cable.
| Pros | Cons |
|---|---|
| Dialogue is clear and easy to hear even with built-in audio alone eARC support makes adding a soundbar effortless Can also connect to existing equipment via optical digital / 3.5mm |
HDR and Streaming Service Compatibility

It supports Dolby Vision and HDR10+. For most apps, if the title supports the format, it automatically switches to the optimal mode. If it does not switch properly, check the title’s page within the app to see if “Dolby Vision” or “HDR” is indicated.
When using UHD Blu-ray players or external streaming devices (such as Fire TV), reviewing the device-side output settings (such as turning video output to “Dolby Vision/HDR On,” and adjusting deep color/color gamut settings) tends to improve stability. Audio can be easily split by using eARC to send video to the projector and sound to a soundbar.
| Pros | Cons |
|---|---|
| Supports major HDR formats, making it easy to benefit from streaming Easy to expand with external streamer + eARC |
Quietness, Heat Dissipation, and Power
28dB is comparable to the quietness of a library. At normal viewing distances, the noise is hardly noticeable. On the other hand, raising the brightness tends to cause the fan to spin more actively and increases electricity consumption. Creating and switching between two modes—such as “Standard” for daytime and “Slightly Dimmer” for movies—makes it easy to keep both noise and power consumption down.
| Pros | Cons |
|---|---|
| Quiet and unobtrusive at standard brightness Standby power consumption is relatively low (general tendency) | The unit becomes warm when used at high brightness for extended periods |
Gaming Use (Smooth Display and Low Latency)

At Full HD (1080p), it supports up to 240Hz/120Hz for exceptionally smooth motion. It also features automatic switching (VRR/ALLM) that adapts to game content to suppress stuttering and reduce input lag.
For competitive or rhythm-based games, you can prioritize motion at Full HD. For single-player games where you want to enjoy scenery and visual beauty, you can prioritize clarity at 4K. The ease of switching between these modes is a major strength.
It also provides a brightness adjustment feature (Black Equalizer) to make enemies easier to spot in dark areas, as well as a function to display a targeting reticle in the center of the screen.
Ms. GadgetIs latency noticeable during 4K output? Is 1080p better for competitive play?
Mr. GadgetFor competitive focus, high refresh rate 1080p (120/240Hz) is recommended. For solo play or scenery-focused titles, prioritizing 4K visual beauty is great—switching based on the title makes for a very comfortable experience!
Ms. GadgetCan 120Hz be used with the PS5?
Mr. GadgetYes. It can be used with compatible games. Enable 120Hz (or Performance Priority) in the PS5 settings and use a 120Hz-compatible HDMI cable.
| Pros | Cons |
|---|---|
| Smooth display up to 240Hz/120Hz at 1080p Automatic switching to low-latency settings (ALLM) Improved visibility in dark areas and convenient crosshair display |
Smart Features and Operability (Google TV)

With Google TV, you can install and use necessary apps (Netflix, Prime Video, etc.) directly on the unit. You can jump straight to your desired streaming service from the home screen, and searches can be quickly initiated using remote voice control.
Mr. GadgetThis is genuinely convenient!
You can operate everything easily as long as you have a smartphone!
Turning on the power activates autofocus and auto keystone correction, making it convenient how quickly you can get ready for playback.
| Pros | Cons |
|---|---|
| Major VOD services can be used directly on the unit Straightforward initial setup Fast time-to-playback thanks to AF/auto-correction | Logins and permission settings are required |
Ms. GadgetAre app additions and updates difficult?
Mr. GadgetYou can operate it just like a regular smart TV via the Google TV store. Voice search is supported, and initial setup is simple by following the guide.
Ports, Expandability, and Wiring

There are 2 HDMI ports for video input. If you want to connect game consoles, external streamers, and recorders all at once, inserting a switcher (4K/8K compatible) in between makes things seamless.
- Cabling Tip: An HDMI 2.1-compatible cable is recommended if you are using long runs of wiring or 4K/120Hz. Quality variations tend to show over long distances.
| Pros | Cons |
|---|---|
| Sufficient port configuration for everyday use Local video and photo playback possible via USB Simple audio enhancement via eARC support | Only 2 HDMI systems, requiring some ingenuity for simultaneous multi-device connection |

A bright unit for the living room that lets you “place it and watch immediately”
The ‘HORIZON 20 Pro‘ is a stationary projector equipped with 4K (3840×2160) x RGB triple-laser light source, a rated 4,100 ISO lumens of brightness, Harman/Kardon 12W x 2 speakers, and Google TV. Its appeal lies in how easily it creates an experience where you can “place it, point it, and watch right away” thanks to lens shift (vertical ±120% / horizontal ±45%) + optical zoom offering high installation flexibility.
Brightness is in a class where subtitles remain easy to read even in a daytime living room. The color gamut is wide at BT.2020 110%, and DBLE gives the impression of successfully balancing deep shadow details with sharp highlights. In environments exposed to direct sunlight, using curtains is realistic, and please note that contrast tends to soften under direct midday sunlight.
Initial setup is swift with autofocus + auto keystone correction. Following the procedure of prioritizing lens shift to align the screen position and keeping keystone correction to a minimum helps preserve high resolution. While the unit has a solid weight of approx. 4.9kg, making it well-suited for stable placement, it is not designed for portability.
Video format support includes Dolby Vision / HDR10+ / IMAX Enhanced. For gaming, it supports 1080p at up to 240Hz/120Hz (rated 1ms) and VRR/ALLM, making it easy to switch between motion-focused and image-quality-focused modes. Audio is eARC-compatible, making enhancements via a soundbar straightforward.
With Google TV, major VOD services like Netflix and Prime Video can be utilized entirely on the unit. Voice search and shortcut launches from the home screen made operation snappy and responsive!
Mr. GadgetIf you are aiming for a setup where things are “properly visible” even in a bright living room, this class provides great peace of mind. The high installation flexibility is also a huge help!
