Obviously you can't expect large projector quality or HD levels of sharpness from the H03, but nevertheless the image it produced was dynamic, engaging and detailed up to around 60 inches – and frankly had no right coming out of something this small and affordable.
In a darkened room, colours were vibrant but not too oversaturated, with fairly realistic skin tones and natural greens. A slight lack of sharpness due to the low resolution and relatively unsophisticated lens might even be considered to add to the cinematic feel. What's especially impressive is that, with lamp brightness set to normal and when projecting on a decent surface, blacks are black and dark detailing is surprisingly good, revealing detail that's lost on many TN-based LCD screens (like those you get on most laptops and cheap monitors). Just keep in mind that due to the H03's lack of optical zoom, you'll need a long throw distance to get a big picture.
Audio from the pico projector's tiny mono speaker was never going to be great but it's certainly adequate for presentations and – in a pinch – just about bearable for films. Of course you can always hook up external speakers using the headphone jack, and though in one instance it transmitted noise to a set of headphones we tested with, in general there were no problems.
The projector itself produces an audible hum as soon as you turn it on, which is slightly reduced in Eco mode. It's definitely noticeable in a quiet environment but is never intrusive enough to be annoying. After running at full brightness for a while, the H03 becomes warm but never hot to the touch.
One of the best things about this impressive little projector is its price, which at a mere £204 is considerably lower than its nearest rival, the Optoma PK301 (though this does offer HDMI out and a remote control). If you don't mind something considerably larger, the portable BenQ GP1 is also an option, but despite its superior specifications we feel the H03 is not only considerably cheaper but also more attractive and versatile. As long as you have access to a darkened room and a large, flat surface, you're essentially walking around with a 60in (albeit not HD ready) TV in your pocket.
Samsung's tiny H03 pico projector offers appealing looks and great presentation combined with decent battery life, above-average performance and more features than you can shake a long stick at (including native document viewing and video playback). Its only real flaws are awkward controls and a lack of any digital video input, but its bargain price makes that easy to forgive.
