It is a device from the range of Amazon Warehousedealz and the state has been called "very good". In fact, one could only recognize that the device had already been unpacked and the counter stood at 2 hours.
The installation worked flawlessly and smoothly. The projector was connected by a 5 meter long HDMI cable to a HTPC, so on a multimedia PC. The power cable made on me by the way not inferior sense of how it was to be read elsewhere. I had no abdominal pain to use it.
The commissioning was also done the same. The computer recognized the projector immediately after setting the correct screen size in Beamer (overscan) was equal to the first Bluray be tested.
It was Avatar by James Cameron and I was fascinated by the fantastic picture which is made wide on my canvas. Before I very random into raptures, let me say that I have next to Avatar, the Lord of the Rings (Part 3), Ratatouille and King Kong, I have fully tested yet seen other films of different formats.
It was visible to me and three other people, no rainbow effect. There were, even in fast action scenes no streaks or other unpleasant side effects visible, which can hold a DLP projector ready.
Tiny little criticism would be the fan noise in the normal mode. Sensitive people might be bothered by it. In Eco mode, the problem has disappeared, or the projector very quiet.
The build quality is good to very good, the remote controller responds immediately. The menu of the projector is very clearly structured and intuitive to use. In the instructions I will have to look only to the first filter cleaning.
The ceiling mount, the Amazon has recommended me for this projector, incidentally, does not fit and you should look for the specially designed for this device Deckenhalter.
The lack of HDMI cable I did not miss, but glad that there are today still transport bags in the standard specification.
Meanwhile the Acer H7531D 50 lamp hours under his belt. The longest continuous operation took about 15 hours without that the projector showed even the hint of fatigue or overheating.
From me an 99.9% term buy rating and 5 stars.
Addendum: Today there are 150 hours which is the projector in operation and I'm still very satisfied.
The rainbow effect is still no SEEN.
The projector is now hanging on a holder called B1, which is not offered on Amazon.
It offers a lot of setting and makes a high impression. They also cost just under 30 euros. The holder is also suitable for mounting on a pitched roof!
