The first of images in the player above shows a wide shot of my screen with the P700 in front on a small tripod, projecting a 72" diagonal image. That's followed by two more photos showing the amount of light in the room from partially open shutters, rear lights, and coming in from a skylight in the adjacent room.
So, in summary, the P700 is still extremely impressively bright for a projector that can run on batteries. And, when running on AC, you can choose that mode, or one of two much brighter modes.
Keep in mind that 741 lumens is impressive. While todays basic lamp based projectors are mostly 2000 to 3000 lumens, 750 lumens is enough to do a respectable job in a classroom or small conference room. For many years, 800 to 1000 lumen projectors ruled those environments, and many, if not most of those are still in use today!
Now if you are taking this projector home, consider the brightness this way. In a fully darkened cave or home theater, with a normal screen of 1.1 to 1.3 gain (figure a white (not off-white) wall to be about 1.0 gain), you need less than 450 lumens to properly fill a 100" diagonal screen. With 741 lumens that technically means you have enough brightness for that room for a 150" diagonal screen.
Seriously, until 3D became a standard feature on higher end home theater projectors almost all of them produced calibrated output of between 500 and 900 lumens. Of course if you are going to use the projector in less ideal circumstances you'll probably want to keep image size to 100" diagonal maximum when plugged in, and to about 50" diagonal on battery (about 72" diagonal in a dark room).
Overall, sharpness, which I've mentioned previously, is rather good for a pocket or pico projector. Expectations aren't as high for these projectors as lamp based ones, as there's more tendency to be sharper in the center, rolling off to the corners.
The P700 however, was pretty good in that regard, as you can see from the photo I just took, of this paragraph. And there's a closeup above showing the small menu type as well.
There is one issue however. The P700 tends to de-focus a bit in the first 5-10 minutes of use. That is, if you immediately focus it, you'll notice a bit later on that the image is a bit softer. This too, is not an uncommon issue with these small projectors, and some large ones.
Just figure that you'll probably want to quickly readjust the focus after those first 5-10 minutes, for best picture. Or, if you are routinely using the P700 from the same distance each time, Wait 10 minutes before you first focus it. Then when you power up in the future, it will be a little soft, but sharpen up.
All considered, this is a WXGA projector - 1280x800, just slightly higher than 720p. That means it's using the most popular resolution these days for business, but not as high as most over $700 home projectors, which tend to now all be 1080p: 1920x1080. In that regard, a lamp based projector for your home, if you are spending the extra, will provide a real difference in detail. At this time, there are a couple of 1080p resolution pocket projectors, but they are all in the $1000+ price range, so over twice as expensive.
For a DLP, the amount of basic background mosquito noise seems reasonable to low, more comparable to LCD projectors - that's a good thing. No real issues in terms of image noise. I did not notice any particular issues in terms of motion artifacts either.
