An ultra-short-throw projector sits close to the projection surface, but that common form factor does not make the devices interchangeable. Different throw ratios change the depth required by the cabinet. Different light technologies respond differently to colour, motion and individual perception. Integrated speakers may be sufficient in a simple living-room setup, while an existing audio system calls for other connections. The supported picture size is not just a number either: as the surface grows, luminance falls, unevenness becomes more visible and the seating position matters more.
Method: room questions instead of a winners’ list
The five models were chosen because they represent different technical profiles. We compare only information documented on official manufacturer or support pages. There is no weighted score because any weighting would be arbitrary without a specific room. A compact enclosure does not help if the projection surface is rippled; a high light-output figure does not solve direct sunlight; and a low-latency game mode is irrelevant when the only sources are films.
Before reading further, it helps to write down six questions. How wide is the clear wall? How deep can the cabinet be? Which ambient lights will actually remain on? Will the integrated sound be used? What resolution and refresh rate does the source provide? Can the projection surface be installed permanently flat? The answers create a personal set of criteria against which the following profiles can be assessed.
Brightness, contrast, latency and picture-size range are stated as manufacturer specifications. Where measurement methods or signal conditions differ, we do not construct a direct ranking.
Five profiles at a glance
| Example | Optics and light | Picture range | Sound and signal | Planning profile |
|---|---|---|---|---|
| Epson EH-LS800B | 3LCD, laser; 4,000 lumens white and colour light output | 80–150 inches | 20 W Yamaha system; HDMI ARC | Very short placement, high light requirement |
| Hisense PX3-PRO | TriChroma laser; 3,000 ANSI lumens | 80–150 inches | 50 W Harman Kardon; eARC | Broad all-round profile with a gaming focus |
| Samsung The Premiere 9 LPU9D | Triple-laser DLP; 3,450 ISO lumens | 100–130 inches | 40 W, 2.2.2 channels; eARC | Narrower size range with integrated media interface |
| LG CineBeam HU915QE | Laser; 3,700 ANSI lumens | 90–120 inches | 40 W, 2.2 channels; three HDMI inputs | Living-room profile with brightness sensor |
| AWOL Aetherion Max | RGB triple-laser DLP; 3,300 ISO lumens | 80–200 inches | Integrated multichannel sound; eARC and S/PDIF | Wide size range and fast signal modes |
The light-output figures deliberately appear without an overall placing. Epson states white light output under ISO 21118:2020 and colour light output under IDMS 15.4, while other examples use ISO or ANSI lumens. These figures provide orientation within each specification sheet, but they do not constitute a complete visual comparison without identical test conditions. Dynamic and native contrast figures cannot be merged into one scale either.
Putting the five models in context
Epson EH-LS800B: short distance and a 3LCD profile
Epson states 4,000 lumens for both white and colour light output and a picture range of 80 to 150 inches. The 3LCD system does not produce the primary colours through one colour wheel split over time. That can matter to viewers who perceive coloured flash artefacts with certain DLP systems. Epson documents a very small gap between the enclosure and wall for an 80-inch picture; the full enclosure depth, connectors and ventilation must still be included in the furniture plan.
This profile suits a brighter living room in which short placement and an integrated audio system are important. The manufacturer states less than 20 milliseconds in game mode, while also noting that there is no single official standard for input-lag measurement. That qualification shows why individual figures should always be read together with the signal format and measurement route.
Hisense PX3-PRO: an all-round profile with clearly identified gaming functions
The PX3-PRO is described with an 80-to-150-inch range, a 0.22:1 throw ratio and 3,000 ANSI lumens. Its integrated 50 W Harman Kardon system may initially remove the need for separate audio equipment in a simple setup. Hisense also lists a low-latency mode and High Speed Refresh up to 240 Hz. The underlying resolution needs to be checked: a high refresh rate at a reduced signal format is not the same as 4K at that rate.
This profile is relevant where films, sport and games have equal importance. The familiar UST planning rules still apply: the surface must be flat, the enclosure needs a stable position, and light arriving from the side is easier to control than light falling directly on the picture.
Samsung The Premiere 9: a defined picture-size range
Samsung states a range of 100 to 130 inches, 3,450 ISO lumens and a 0.189:1 throw ratio for the LPU9D. Three HDMI inputs, eARC and an integrated 2.2.2-channel system make a compact signal path possible. The narrower size range can be a useful planning boundary: furniture, viewing distance and frame can be designed around a clear target instead of pursuing a theoretical maximum diagonal.
According to the manufacturer, a flat, pale wall can serve as the surface in principle; Samsung points to a UST-compatible projection surface for an optimised result. Gaming Hub and Game Mode are documented, but the German product page does not provide a specific latency figure. We therefore add no estimate or inferred comparison figure here.
LG CineBeam HU915QE: brightness adaptation in a living room
LG lists 3,700 ANSI lumens, 90 to 120 inches and a 0.19 throw ratio. An ambient-light sensor and Brightness Optimizer II are intended for changing light conditions. Automation of this kind cannot replace sensible light control, but it can simplify day-to-day use between afternoon and evening. The integrated 2.2-channel, 40 W system and three HDMI inputs also support a setup with fewer devices.
This profile suits a living room where the projector regularly operates under changing conditions and the picture remains within the documented size range. The stated wall distances differ substantially by diagonal. Planning should therefore use the installation drawing for the actual surface selected, rather than a single generic distance.
AWOL Aetherion Max: one example with a wide picture range
The AWOL Aetherion Max is one of five technical examples in this comparison. The manufacturer states a range of 80 to 200 inches, a 0.2:1 throw ratio, 3,300 ISO lumens and an RGB triple-laser light source. Different latency figures are documented for gaming according to the signal: 2 milliseconds at 4K/60 Hz, 4 milliseconds at 1080p/120 Hz and 1 millisecond at 1080p/240 Hz. The shortened claim “1 ms” therefore does not apply to every output format.
Search forms such as awol.de, awol de and awol aetherion max often lead straight to one model. A more useful selection question is whether the documented size range suits the actual wall, whether the surface remains flat at the target size and whether the whole signal chain supports the intended mode. The official German-language presence of AWOL is documented at awolvision.de; its inclusion here is neither special emphasis nor a quality judgement.
Reading light output and contrast without false precision
A lumen figure does not directly describe how bright a specific picture will appear from the seat. The surface spreads the light output, so a larger diagonal reduces luminance at the same output. Screen gain and directionality change how much light reaches viewers. Ambient light and pale walls also raise the perceived black floor. A smaller picture in a controlled room can consequently look much more dimensional than a maximum diagonal under direct daylight.
The unit and measurement method belong with the figure. ANSI and ISO values follow defined but not identical procedures, while colour light output under IDMS addresses an additional question. Dynamic contrast figures often use control that varies over time, whereas native contrast describes a different state. A fair comparison identifies the type of figure instead of arranging every number in a superficially precise ranking.
Which emphasis suits each room profile?
| Room profile | Priority criteria | Less useful shortcut |
|---|---|---|
| Bright living room | Light control, UST-compatible surface, real target size, quiet daytime mode | Choosing only the highest light-output figure |
| Compact media wall | Throw ratio, enclosure depth, connectors, ventilation, defined picture range | Considering only the wall gap |
| Evening film room | Black-level appearance, reflection control, restrained processing, acoustics | Directly equating dynamic contrast figures |
| Mixed use | Separate profiles, operation, audio route, source switching, stable HDMI path | Enabling every automatic function at once |
| Gaming focus | Signal-dependent latency, refresh rate, VRR/ALLM, direct connection | Generalising from a single millisecond figure |
The table shows why the same device can make different amounts of sense in two rooms. Anyone who moves frequently or changes furniture should leave extra depth, picture-size and cable-routing capacity. A permanent media wall can be planned more closely around one diagonal. Where daylight changes, controlling the surroundings is often more effective than adding another picture mode.
Checklist before deciding
- Draw the wall and cabinet in centimetres. Include the enclosure, distance, connectors, airflow and frame in one plan.
- Choose a target size, not the maximum. Simulate subtitles and menus from the real seating position.
- Map the light sources. Assess direct, lateral and reflected light separately.
- Define the projection surface. Settle flatness, viewing area, installation and UST suitability before picture adjustment.
- Decide the audio route. Integrated speakers, eARC or an AV system determine the wiring.
- List the source signals. Note resolution, refresh rate, HDR and game mode for every source.
- Check the manufacturer’s installation drawing. General calculators do not replace the documentation for a specific model.
