Frequently Asked Questions about Optoma EW531 Projector

Our support team searches for useful product information and answers to frequently asked questions. If you find an inaccuracy in our frequently asked questions, please let us know by using our contact form.

Can I power off my projector immediately after use? Verified

After using the projector the lamp is still very hot. It is best to leave the projector on after use, giving the internal fan time to do it's work and cool the lamp. This will extend the lifetime of the lamp.

What is keystone correction? Verified

A projector can often not be placed straight in front of a screen or wall. The projected image can become distorted because of this. This is the keystone effect. Keystone correction is a feature that addresses this distortion. Not all projectors offer keystone correction.

What is the contrast ratio? Verified

The contrast ratio tells how far the whitest white is from the blackest black. A contrast ratio of for example 400:1 means that the blackest black on screen is 400 times darker than the whitest white. A high contrast ratio contributes to the sharpness of the image.
