These projectors usually have adjustments to align the panels in their menus.ĭepending on the projector, it's possible not every part of the image will be in focus at the same time - that's one downside to low-cost lenses. If the red panel is misaligned, each pixel might have a red edge. It could look like each pixel has an edge that's a specific color. This might appear like a focus issue, with an inability to distinguish individual pixels. If you have a three-chip projector, either LCD, LCOS, or very high-end DLP, it's also possible each chip isn't precisely aligned. I once used binoculars to get the focus correct on a particularly long-throw, high-resolution projector, but I doubt most of you will need to resort to this, not least because you'll look as ridiculous as I did. Some projectors have focus you can adjust with the remote, or in the case of the Viewsonic M2, autofocus. I believe this is the main reason people have children. If you can't make out the pixels at all from where you're standing, enlisting a hapless, well-sighted aide will work. The technical term for this is "annoying." The main issue with this type of focusing method is that you're standing at the projector, and the screen is on the other side of the room. I've reviewed a few projectors that have focus wheels that stick, or don't move smoothly.
#BEST OVERHEAD PROJECTOR MANUAL#
With analog, manual adjustments, you're actually more likely to get perfect focus as there are typically no "steps" to the adjustments, just a smooth analog rotation of the focus wheel. If your projector is on a stand, you could experiment with nudging it backward a fraction of an inch, if the focus is in between one of its steps. As long as you're close it should look fine when you're seated. Sometimes, even with high-end projectors, the adjustments will be too coarse to get perfect. Adjust the best you can, but ideally each pixel will be obvious when you're standing at the screen. You should be able to make out the darker outlines, however.
It's possible they'll be too small to see, depending on the size of your screen, the resolution of the projector, and your eyesight. With a motorized focus, stand up at the screen and slowly adjust until you can see the individual pixels. These will typically have bright lettering on a dark background, which should help. Barring that, you can bring up the user menu, and use that. With both options, I find it best to use a bright image, or the bright part of an image. There are pros and cons to each of the main types, and how best to achieve the sharpest focus possible. Once in a while you'll find one that has autofocus. Most projectors have manual focus adjustments, either using a wheel attached to the lens, or motorized. It's why most theaters have the area around the screen painted black. There's not much you can easily do about it, and it's quite common. With inexpensive projectors, this is often a squarish halo of light spilled around the screen.

#BEST OVERHEAD PROJECTOR MOVIE#
So for those occasional mid-day movie marathons, sporting events, etc, anything that cuts down the glare should work. If you're watching a lot of content during the day, a projector might not be the best primary option anyway. If your spouse doesn't like the look of blackout curtains, any heavy curtains or shades will help. In a few years, you're going to need to buy curtains to see anything, so you might as well get them now. Even if your projector does OK during the day when you buy it, the lamp is only going to get dimmer over time.
#BEST OVERHEAD PROJECTOR TV#
If you're planning on watching TV during the day, you're going to need to cut down the light in the room. Even if you have a fancy light-rejecting screen, ambient light is bad and you're going to want to do everything you can to reduce it. Lessen ambient lightĪny light in a room that's not created by the projector is going to reduce image quality. The exhaust from most projectors is hot enough that if it's blowing right in your face, it's a bit annoying.
