For anyone who sees rainbow artifacts easily and considers them annoying, the EF12 is a prime candidate for a 1080p room-to-room portable projector, and even preferable to any current portable 4K model, none of which is guaranteed to be rainbow-free. In our tests, the EF12 delivered good image quality, and although it didn't deliver as high a maximum brightness as some competitors did, it had a brighter image for the picture modes that you'll actually want to use. The UHD40 is also still available with certain vendors too, here at Bax, for example - https://www.bax-shop.co.uk/projection/optoma-uhd40-4k-ultra-hd-projector That said, if you're looking for a big picture then the price differences start to disappear. 4K TVs become very expensive at their largest sizes, and projectors effortlessly deliver bigger images than even the biggest mainstream TVs.

Most such models use four sets of 1,920 by 1,080 to put a full 3,840 by 2,160 matrix on screen. The majority of Epson's pixel-shifting models use two sets, which puts only half as many pixels on screen. But largely thanks to the limits of human visual acuity, the image using Epson's approach is impossible to distinguish from a full 3,840-by-2,160-pixel image, unless you're far closer to the screen than normal seating distances.The GV30 also offers a built in rechargeable battery, an unusual extra for a room-to-room portable, and a drop-proof rating of up to 27.6 inches—the distance from hand to floor when you're carrying it or tabletop to floor when you're not—which is unusual for any projector. Who It's For

The disks are 'chunky' so easy to hold, and robust so they won't break if dropped by a playful child (Image credit: Lorna Jordan)Then there are portable projectors, which are ideal of taking on the go or using outside to create a grab-and-go cinema experience. They might not match up with the performance of dedicated home cinema projectors – the fact that none have made our list should tell you that – but you're paying for the experience and versatility here. You can't beat an open-air cinema experience under the starry night sky after all.

Although projector categories change from one manufacturer to another and evolve over time, the application categories are consistent, if somewhat overlapping. Here's a brief look at the most common categories and subcategories of applications, and which features are most important for each. The Xgimi Halo+ belongs on the short list for anyone who wants a smart (streaming-capable) portable home entertainment projector that's easy to carry and set up, delivers robust enough audio so you don't need to lug an external sound system, and has its own battery so you can use it without needing a power outlet. What the Halo+ stands out for, however, is its well-balanced constellation of features, with high brightness chief among them.It’s a different story when you start looking at ultra-short throw models (UST), though. These are designed for smaller spaces and can sit right close up to the wall (on your TV stand or cabinet) and many can display a massive image from around 40cm away from the surface you’re projecting onto. For minimal home decor, you may consider USTs as a replacement for a traditional flatscreen TV – they’re just as versatile. All-in-One Projectors We test using a wide range of content from 4K Blu-rays, to streaming services, video games and standard definition DVDs to make sure all kinds of content are put through these projectors. This helps us find the strengths and weaknesses of each projector. With its 4,000 lumens brightness spec, this Epson ultra short throw is a perfect option for viewing sports in a well-lit room, and it also has a Yamaha-designed built-in speaker system that creates a strong virtual surround sound effect.
