Acer C20 Pocket Projector Review

After viewing that, that is, in our online stores, I bought myself this miracle
Attention, traffic!

I got an idea to hang a large plasma in front of the bed in front of the bed, but looking at the cost and the idea died in the bud. As a result, I looked towards the projectors - and there is a bummer, my room is small and there is no place where this is a miracle story, put . And then at work one of the clients ordered a pico projector, remembering about this miracle, walked through the reviews and what was available from us and took the Acer C20.

Let us turn now to those data, and puppy delight will continue further

I brought this toy home and started playing ...
The first thing that struck was that there was no adequate paper instruction, as it turned out that it was not necessary, since everything is simple. The following was pleasantly surprised by the fact that this huge number of various cables included. However, there will be no HDMI cable included .
Also, the manufacturer did not forget about the case of some leatherette.

In general, on the way home, I of course dropped a couple of files and it was fun to display a picture of the whole house and scare people on the subway, but the main games were at home.
Connecting to a laptop, I quickly installed it on a tripod, by the way it was not included either, and I watched a movie for half a night, then turned it off and got burned. I did not expect that such a kid is capable of such. In general, I was pleased with the picture quality. The day has come and I took it with me. Disappointment befell me immediately. In daylight, the picture is not visible at all ...

But I am not depressed, since I am friends with a soldering iron and I understand electronics very well.
Having come to work first thing I disassembled it.
In the inside, I really did not find anything interesting, only a small fee and a vast number of radiators. Having closed the projector, I decided to google the names of the chips from the projector. And the very first link got to the service manual for the animal. My surprise was no chapel.
In general, for those who swing laziness, in the course of the service: Menu - Menu - Menu-Left-Left-Menu
All the actions that you will do there you do at your own peril and risk, but I can say with confidence that by tweaking the settings I improved the picture quality but also reduced the life of the diodes in the same way, so be careful.

To summarize:
For home use (watching movies in the evenings) is ideal for your money.
