LG CineBeam S PU615U compact ultra short throw 4K projector with RGB laser
Product description
What to know before you buy
The LG CineBeam S PU615U is a compact ultra short throw 4K projector designed for people who want a big, cinematic image without needing a long throw distance. In practical terms, that means you can often get a proper screen size by placing the unit close to the wall and letting the ultra-short throw lens do the work.
On paper it leans into a “cinema-at-home” feel: 4K UHD resolution, RGB Laser, and LG’s mention of a wide colour gamut (DCI-P3 154% Overall) plus a high contrast ratio rating of 450,000:1. It’s also built to be easy to live with thanks to auto screen adjustment, plus smart connectivity via LG webOS and both Wi‑Fi and Bluetooth.
That all sounds promising, but it’s worth keeping one limitation in mind: projector brightness and image performance can be heavily affected by room lighting. With 500 ANSI lumens specified, it’s a good match for controlled lighting rather than bright, daytime rooms.
The essentials
This is an ultra short throw projector aimed at creating a large display in limited spaces. LG states it can project a screen range from 40 inches up to 100 inches, using an ultra-short throw lens that’s meant to work even when your room is tight.
If you’re setting up a TV replacement in a lounge (or a secondary “watch anything” screen in a bedroom), the placement convenience is the headline. For example, you could mount or place it near your wall, then adjust until you’re getting the size you want—something that’s usually less fiddly than setups that need a longer projection distance.
The specification also targets image quality and colour. LG references vibrant colour and deep blacks using the DCI‑P3 154% colour gamut and the 450,000:1 contrast ratio claim. Whether you’ll see the full difference versus simpler projectors depends a lot on calibration and your viewing conditions, but the direction is clear: this model isn’t just about “getting an image”, it’s about getting one that looks rich.
Key features that matter day to day
The real-world appeal of the CineBeam S PU615U is how many viewing and setup tasks it tries to handle for you.
Auto screen adjustment is designed to reduce the “messing about” stage when you change position or set it up in a new spot. And with LG TV webOS included, it’s meant to feel closer to a TV experience than a bare projector box.
Connectivity is also fairly modern for everyday use: Wi‑Fi and Bluetooth are available, with USB‑C and HDMI for wired options. That gives you flexibility for streaming devices, consoles or other sources—depending on what you already own.
One more practical note: it’s described as a compact unit. In UK homes where space is often the limiting factor, that matters as much as the resolution.

Who it suits, and where it may fall short
It’s a solid fit if you want a large screen in a room where a long throw distance isn’t realistic, and you care about colour richness and contrast on a 4K UHD projection.
It may not be a great match if your priority is bright, high-ambient daytime viewing. With 500 ANSI lumens, the image will likely work best when you can control light—think evenings, dimmed curtains, and dedicated movie/game sessions.
Also, if you’re the type of buyer who expects the easiest “set it anywhere and forget it” experience, do consider the reality of projector placement and screen sizing: ultra short throw helps, but you still need to position it well for the cleanest results.
Final verdict
When it makes sense
Buy the LG CineBeam S PU615U if you’re trying to create a 40–100 inch cinema-style setup in a compact space, and you want the combination of 4K UHD, RGB Laser, and LG webOS for day-to-day streaming. The ultra short throw approach should reduce the hassle of layout planning.
It’s not for you if
Skip it if your room is often bright or you regularly watch in strong daylight conditions, since 500 ANSI lumens may not deliver the punch you’re expecting.
