LG CineBeam S PU615U
For people in small spaces, this is the rare projector that gives you a 100-inch screen without turning the room into a science project.
If you want a **4K projector** that works in a cramped living room, bedroom, or apartment without a ceiling mount, the CineBeam S is built for that exact problem. It throws a huge image from absurdly close to the wall, then layers in LG’s smart-TV-style webOS so streaming feels familiar instead of fiddly. ## What makes it worth it The headline feature is the **ultra-short-throw lens**: LG says it can do a **40-inch image from 8.1cm** and a **100-inch image from 39.3cm**. That makes it far easier to live with than a normal projector. The **triple RGB laser** system covers **154% of DCI-P3** and the claimed **450,000:1 contrast ratio** give it the kind of colour and depth you usually don’t associate with a compact projector. And because it runs **webOS**, you get built-in streaming apps, plus **Wi-Fi, Bluetooth, USB-C and HDMI** for easy setup. ## Where it falls short Brightness is the obvious compromise. At **500 ANSI lumens**, this is not the projector you buy for a bright room or casual daytime viewing with the blinds open. Reviewers also note that keystone and auto-alignment work best when the placement is already close to ideal, and gaming input lag is only fine for casual play. Buy this if you want a space-saving **home cinema projector** for controlled-lighting movie nights and easy streaming. Skip it if you need a bright-room projector or you plan to use it mainly for fast gaming.
