Preparatory work/about to start work
Before the projector size test, you need to prepare a projector, a computer or other video source, and a flat white background (wall or projection cloth).
Find the right position
Put the projector in a suitable position to ensure that the picture is centered and keep a proper distance from the wall. Find a clean white wall or prepare a projection cloth to ensure a clear picture.
Select a test image
Select a test image of 16:9 in the computer and copy it to the video source to open it.
Adjust projector parameters
Adjust various parameters of the projector, such as focal length, brightness and contrast, to achieve the best picture definition.
Resize the image
Resize the image to ensure that it is completely displayed on the screen and the size meets your needs.
Confirmation resolution
In the setup menu of the projector, find the option of "Resolution" or "Pixel Size" and confirm that it meets the requirements of the project.
Measure size
In order to be more accurate, you can measure the width and height of the image with a ruler or tape measure and compare it with the equipment specification table.
Complete the test
Don't worry, although the steps seem complicated, it is not difficult to test the projector size as long as you are careful. After completion, if the sizes are inconsistent, just adjust the projector settings.
