Taotaole Projector User Manual How To Make Image Brighter In Photoshop

While just about every projector generates a bright, crisp image in a perfectly dark room, business projectors frequently need to do it in a conference room setting with the lights on. Doing this requires a projector with a high light output, or lumen, rating. However, this is only the first step. To get the most output from the projector, presenters need to choose the correct settings and keep the projector in good condition. At the same time, they can make better use of the projector's maximum output through intelligently positioning it and making good choices about how they configure the room and its lighting.

Getting More Lumens

Window Projection- Projector should be set up within 4’ to 8’ from the window you will be using. Use the included Projection Screen with two-sided tape to attach to your window. Stretch it tight to minimize creases in the fabric. Be sure to place the Projector on a stable surface and use the tripod for improved viewing angles.

You can use the elevator feet to make adjustments if the surface on which you need to set the projector is uneven or if you otherwise need to adjust the angle of projection. The adjustment range of the elevator feet is 0 to 9 degrees. Big easy driver user manual raspberry pi. Press and hold in the elevator buttons. Raise or lower the projector to the desired height.

Step 1

Clean your projector's lens. Smudges, fingerprints and dust all block the light coming out of your lens and prevent it from getting to the screen.

Step 2

Set your projector's lamp to its highest setting. Some projectors have a lamp button that you can press to increase its light output. Others will require you to go into the menu to do this. Bear in mind that your lamp may burn out more quickly when you use it in its brightest setting.

Step 3

Choose the presentation mode that gives you the greatest light output. Generally speaking, modes like 'Eco,' 'Cinema,' and 'Movie' will dim your projector to provide energy savings or better performance in the darker parts of an image. If brightness if your greatest concern, look for modes like 'Normal,' 'Bright,' or 'Presentation.' Because projectors are different, you will need to look at every option to see which is best for your particular device.

Step 4

Replace your bulb if it is getting old. Many projector bulbs dim as they age, with some losing as much as one-half of their brightness. If your bulb is nearing the end of its life, putting in a new one could make a significant difference in your projector's perfomance.

Step 1

Control the lighting in your room. While it might be impractical to completely dim your room, doing basic things like turning off lights that shine on your screen or covering the windows near your screen can make a big difference.

Step 2

Project a smaller image. The larger the image is, the more spread out the projector's light gets. If you can shrink the image a little bit, it will appear to be brighter and sharper.

Step 3

Keep your projector as close to the screen as you can. Using your projector's zoom lens to project a large image from a distance can reduce your projector's effective brightness by up to 40 percent. If you can, put the projector as close to the screen as you can while still achieving a sharp image of the correct size.

Step 4

Position your projector flat and on-center. Tilting your projector will give you a trapezoidal image. Using image correction to fix this also reduces your projector's effective light output. In the same vein, using a lens shift function to let you position your projector off-center ends up using a less efficient part of the lens and also reduces light output.

Tip

Keep your projector's vents clean. When you run it at maximum brightness, more heat can build up. This makes good air flow even more important.

Color Brightness and White Brightness (Lumens)

Projectors come in a wide range of brightness which are measured in lumens. The brighter the projector the higher the lumen rating, and, all else being equal the more it will likely cost.

When shopping for a projector, be sure to look for two lumen specifications: One for color brightness and one for white brightness. There can be major differences among different projectors and brands, so color should be measured and listed separately to provide accurate information. If the information provided only gives you one lumen rating, it is typically referring only to the white brightness of the projector. The actual brightness of color may be as little as one-third of the lumens stated.

The amount of brightness you need is determined by the room you project in. Projector brightness is measured in lumens. For home theater projectors where ambient light is kept to a minimum, you'll need a minimum of 1500 lumens. For classrooms, conference rooms or rooms with windows, a projector with a minimum of 2500 lumens is best. For large auditoriums or lecture halls, you'll need more lumens.
