    DLPs with "Diamond Pixels" will have issues as Paul's projector showed. But DLP without Diamond Pixel and LCOS devices with the true native resolution will have no problem with the test pattern. Let's see how it looks with LBS.

    It is a darn simple and straight forward test pattern designed to show if a given projector supports the stated resolution.

    BTW, where is LBS "ruling" in picoprojectors? I think its market share is sub 1%.

    Paul Anderson's post reminded me that I came up with a better test pattern later. This one will catch some issues the other test pattern would not. Below is the test pattern Paul used:

    NOTE, the pattern is specific to the TRUE resolution if the device actually has that resolution. A device that actually supports the resolution should have no problems with the pattern.

    How about objectively checking out the resolution of the projector?

    Below is a simple test pattern I generated to objectively test resolution

    The article associated with the test pattern explains about how to measure resolution with a particularly focused on laser scanning issues is linked to below (the shooting instructions at the bottom are hopefully helpful):

    LIPA

    That is precisely what it means. LIPA was organize to support making very large projectors with laser ILLUMINATION and use the word "illuminated" to distinguish themselves from laser "scanning" per slide 19. LIPA contentions (I think correct) is that once you spread the light over a panel, laser light can be even safer that the equivalent lumens of light from a lamp because there is no IR radiation in the light.
