Optoma PK301

Zitat: Geringe Lichtstärke und geringe Auflösung, im Akku-Betrieb noch etwas dunkler als am Netz, deshalb nur für Bildbreite unter 80 cm zu empfehlen. Erträgliches Geräusch.

Zitat: The good: + The PK301 boasts one of the better resolutions in the pocket projector business. While it doesn’t stretch quite into the eye-popping world of HD, the 854 x 480 pixel count is native 16:9 widescreen, making this model more suitable for watching movies than most of its rivals, which are firmly mired in 4:3-sville. + At 50 lumens the image is also brighter than most, and while you won’t be able to enjoy a movie in a well-lit room, you can get a punchy picture if you dim the lights. + There’s a mini HDMI input for quickly hooking up all manner of sources, alongside mini USB and a micro SD slot (32GB compatible), and the built-in battery delivers 1.5 hours of on-the-go use. The bad: - Optoma hasn’t been able to iron out all the issues with pico projector performance, however, and the PK301 tends to get pretty noisy on the fan front once you crank up the brightness. It also struggles to provide a really sharp picture – very noticeable if you’re viewing a 50-inch or larger picture. Oh, and the built-in speakers can only muster 0.5W of power, leaving them tinnier than a tuna cannery. One of the better pico projectors around, undoubtedly – but you still have to trade off a lot in performance terms for that pocket-friendly size.

Zitat: Points forts: + 20 000 h de durée de vie de lampe + Très compact + Bonne visibilité des images dans une pièce noire + Extension de mémoire via micro SD jusqu´à 32 Go + Connectique mini HDMI Points faibles: - Si la lumière est allumée la zone de projection doit être fortement réduite - Plus le contenu vidéo est sombre, plus l´image doit être réduite - Mémoire interne très petite - Gamma faussé qui donne des images un peu brûlées dans les tons clairs - Autonomie de batterie interne 1h30 en mode éco Dans le noir, le PK301 s´en sort bien quel que soit le contenu vidéo proposé. Une fois la lumière allumée, il faut réduire la zone de projection pour voir les images, surtout si ces dernières sont sombres. En qualité vidéo, l´image est correcte. Toutefois, nous aurions préféré pouvoir ajuster plus de paramètres pour corriger, entre autres, le gamma et réduire l´effet brûlé des images les plus claires.

Zitat: The Optoma PK-301´s combination of aspect ratio and brightness put it in a unique class by itself. With a list price of $399 and very fine video and data images, it is well suited for those who do widescreen presentations, or want to watch movies at home or on the road. A variety of sources can be accommodated although some require optional adapter cables. The cost of the highly desirable remote and whatever optional cables you might want will add to the price. As with all pico projectors, ambient light must be controlled to keep the image from washing out and image controls are minimal. But for intimate presentations to just a few people, or movies anywhere at anytime, the PK-301 is well worth a close look.
