An excellent DLP projector with very good colour rendition and with the available range of presets or user settings you are able to configure just hohw you like it. It has 2 lamp brightness settings but we found the longer lamp life theater setting good for viewing in all conditions. It suffers like all DLP projectors from slightly washed-out blacks (hence 4-stars) that can make some very dark scenes loose detail, but this doesn't detract from what is a good overall package. Use with a matt grey screen to improve the contrast. Very easy to set up. Needs M6 bolts if ceiling mounted. Everyone who has seen it has been very impressed and turns watching movies into a cinema like experience - great for kids and adults.
We have a 72" screen (any larger can be too big for the average UK sitting room) and the furthest away the projector can be sited is ~3m because that is the limit of the zoom lens. Projecting onto a larger screen (or mounting closer) would not be a problem. So if you have a larger screen then the projector might have to be in the middle of the room - it is black and may be conspicuous. Before deciding on the samsung, I checked the other similar cost projector and they all suffer similar limitations - check your room size and where you want the projector to go. It's very quiet, we sit right underneath it and can't hear it. All functions can be accessed from the remote control or from the buttons on unit itself.
Connectivity is good but most DVD/Blu-ray players only have one HDMI out so to avoid disconnecting cables everytime you use it, you'll need an HDMI splitter (about £30 from Amazon). The 2 HDMI+SVideo+composite inputs allow you to connect TV/Sat/Games console system to the other inputs as required.
