For a premium large image with strong built-in sound, consider the Hisense L9Q. This shortlist synthesizes published reviews and manufacturer specifications; it is not a standardized head-to-head test, and the prices and bundles available in your market may differ.
How to choose a 4K ultra short throw projector
Ultra short throw (UST) projectors sit close to the wall while projecting a large image. That placement does not eliminate installation constraints: check the exact model’s throw geometry, supported image size, and compatibility with your screen before buying. Ambient light, screen type, furniture height, and the projector’s required distance from the wall all affect whether the setup works in your room.

- For a bright room: Prioritize usable brightness, but compare figures only when their measurement standards match.
- For a dark room: Contrast and color performance may matter more than maximum brightness.
- For a large image: Confirm the supported size and installation range, and check whether a screen is included.
- For gaming or streaming: Check the specific refresh mode, smart-TV platform, and connectivity you need rather than assuming every 4K projector supports the same features.
This selection draws on the current TechRadar roundup and reviews, RTINGS’ comparison of the LS800 and PX3-PRO, Epson and Hisense product information, and a 2026 What Hi-Fi? review. The figures below retain their source and measurement qualifications where stated. TechRadar’s 2026 roundup and the individual sources are useful for checking details before purchase.

| Model | Best fit | Brightness or size information | Key trade-off |
|---|---|---|---|
| Epson EpiqVision Ultra LS800 | Brighter rooms | Epson specifies 4,000 lumens color brightness under IDMS and 4,000 lumens white brightness under ISO; TechRadar lists projection up to 150 inches. | RTINGS finds it brighter than the PX3-PRO, but the PX3-PRO has better contrast and color. |
| Hisense PX3-PRO | Darker rooms and contrast | Hisense claims 110% BT.2020 coverage and 3000:1 native contrast, with support for screens up to 150 inches. | Its quoted color and contrast figures are manufacturer claims, not independent measurements in the cited material. |
| Hisense L9Q | Premium large-image setup and built-in sound | TechRadar lists 5,000 lumens and an 80–200-inch projection range. | It is expensive, and TechRadar’s review says no screen is included. |
| Hisense PX4 Pro | A recent 2026 option with high-refresh gaming | What Hi-Fi? reports Hisense’s claim of 3,500 lumens peak brightness and notes a 1080p/240Hz mode. | Pixel shifting is used for 4K; the cited review does not establish an independently measured brightness result. |

Epson EpiqVision Ultra LS800: the bright-room choice
The LS800 is the clearest pick in this group when the room is not fully light-controlled. RTINGS says it is noticeably brighter than the PX3-PRO and better suited to rooms that are not light-controlled. That is a comparative review finding, not a guarantee that the picture will remain unaffected by daylight or room lighting.

Epson describes the LS800 as a three-chip 3LCD UST laser projector. Its stated 4,000 lumens of color brightness use the IDMS standard, while its 4,000 lumens of white brightness use ISO. Those two figures are not interchangeable with each other or with a brightness number that uses a different standard. TechRadar’s 2026 roundup describes it as a 4K model with projection up to 150 inches. Epson’s LS800 product specifications identify the manufacturer’s brightness ratings; RTINGS’ LS800 and PX3-PRO comparison provides the cited room-brightness comparison.
Hisense PX3-PRO: contrast and color for darker rooms
RTINGS says the PX3-PRO has better contrast and color than the LS800, making it a stronger fit when you can control room light and value darker-scene performance. Hisense advertises 110% BT.2020 color-gamut coverage and 3000:1 native contrast, and says the projector supports a screen size up to 150 inches. Treat the numerical color and contrast values as Hisense claims, not independent test results. The manufacturer also lists Dolby Vision support. Hisense’s PX3-PRO product page gives its specifications and claims.

Hisense L9Q: large projection and a substantial sound system
The L9Q suits buyers seeking a premium, large-image setup with integrated streaming and sound. TechRadar’s 2026 roundup lists 5,000 lumens and an 80–200-inch projection range. Its review reports Google TV, a ten-speaker system, 4K at 60 Hz, and 1080p at 240 Hz. The review also says the projector is expensive and does not include a screen, so account for a compatible screen if your setup requires one.

Hisense PX4 Pro: a newer option for high-refresh gaming
What Hi-Fi?’s September 2026 review says the PX4 Pro uses pixel shifting to produce 4K and supports a 1080p/240Hz mode. It reports Hisense’s claim of 3,500 lumens peak brightness. The cited material does not establish that figure as an independently measured result, so it should not be used as a direct brightness comparison with the LS800’s IDMS and ISO ratings. Check the projector’s exact input and connectivity requirements if high-refresh gaming is a priority. What Hi-Fi?’s PX4 Pro review discusses the model and its stated brightness.
LG CineBeam HU915QE: a picture-quality contender
TechRadar names the HU915QE its best UST projector for picture quality in its 2026 roundup. It lists 4K, up to 3,700 ANSI lumens, and a 90–120-inch picture size. The same roundup flags its high price and some tedious settings as drawbacks. ANSI lumens are the figure TechRadar reports for this model; do not assume it is directly comparable with manufacturers’ ratings measured under other standards. TechRadar’s roundup provides the cited rating and size range.
Rank #4

Brightness numbers and prices need context
Brightness figures from different standards cannot be treated as a single ranked scale. Epson specifies the LS800’s color brightness under IDMS and white brightness under ISO; TechRadar lists the HU915QE’s figure in ANSI lumens. Hisense’s 3,500-lumen PX4 Pro figure is reported as a manufacturer claim, while the L9Q roundup figure is presented by TechRadar without a measurement standard in the cited material. A larger number alone does not prove a better picture in your room.
Likewise, launch prices do not tell you what a projector costs today. The L9Q’s $5,999 / £3,999 figures are its reported initial US and UK MSRP, not a current cross-market price comparison. Check current local pricing, included screens, and bundle contents before deciding; the available sources do not establish a standardized current-price table for these five models.

Check the screen and installation before ordering
UST projectors are particularly sensitive to placement and screen alignment. Confirm the manufacturer’s placement guidance and the projector’s supported image size for your chosen wall or screen. A compatible UST screen may be useful when ambient light or the projection surface is a concern, but it is not a universal requirement. Verify compatibility and size for the exact projector, and note that TechRadar says the L9Q does not include a screen.
- Measure the cabinet or console and the available distance between the projector and wall.
- Confirm that your intended screen size falls within the model’s stated range.
- Check whether the projector’s ports and supported signal modes meet your gaming or media-player needs.
- Verify what is included in the specific regional package rather than assuming a screen or accessory is bundled.
Which one should you choose?
Choose the LS800 if the room is relatively bright and the cited brightness comparison is your priority. Choose the PX3-PRO if you can darken the room and place more weight on contrast and color. The L9Q is the premium large-image and built-in-sound option, with screen cost and local availability worth checking. The PX4 Pro merits a look for a recent pixel-shifting 4K model with a 1080p/240Hz mode, while the HU915QE is the picture-quality-focused alternative in TechRadar’s 2026 roundup. None is a universal winner: match the projector to room light, image size, installation, and the price and package currently offered where you live.
