Universal Projector
Alignment Tool

Because film content hides the errors you are trying to find. A grid shows geometry, focus and edge sharpness immediately; a moving picture disguises all three.

Alignment is also easy to get subtly wrong. A projector can look square while the image is trapezoidal, or look sharp in the middle while the corners are soft, and neither is obvious until there is a straight line to check it against.

The patterns here cover the checks worth making in order: geometry first, then focus, then uniformity.

Only as a last resort. Keystone correction squares the picture by throwing away pixels — it scales the image digitally, so you lose resolution and gain softness, particularly at the edges.

The better fix is physical: move or tilt the projector so the lens is square to the screen, then use lens shift, which moves the image optically at no cost to the picture. A projector with generous lens shift is far easier to place well for this reason.

If the geometry cannot be fixed physically, a small amount of correction is better than a crooked image. But treat it as compensation for a mounting problem rather than a normal step.

Focus on fine detail rather than on the picture, and check the corners as well as the center.

A grid or text pattern at the middle of the screen sets the baseline, but almost every lens is slightly softer at the edges, so the useful adjustment is the one that balances center and corner rather than optimizing either. Focus at the screen you actually have, from the distance the projector actually sits.

Give the projector twenty minutes to warm up first. Optics and chassis move as they reach temperature, and a projector focused cold usually drifts.

The one the screen is, not the one the projector defaults to.

A 16:9 screen is aligned to a 16:9 pattern. A 2.35:1 scope screen is aligned to the image the projector actually produces on it, which depends on whether you are using an anamorphic lens or simply zooming the image wider — those need different setups.

The tool supports 4:3, 16:9, 21:9 and custom ratios so the pattern can match the screen rather than the other way round.

Once after installation, once after the projector has been running a few weeks, and then whenever something changes.

Mounts settle, buildings move seasonally, and lamps or lasers shift slightly as they age. A projector that was perfect at commissioning can drift enough over a year to be visibly off at the screen edges.

It is a five-minute check with a grid pattern, and much easier to notice with one than without.

No, and the two are often confused. Alignment is geometry and focus — getting the image square, sharp and correctly sized on the screen. Calibration is color, grayscale and gamma, measured with instruments.

TekScene includes configuration and optimization with every installation: lens shift, zoom and focus, picture modes set for the room, and HDR matched to the screen size and gain. Full instrumented calibration is a separate service, priced by scope.

This tool covers the alignment half, which is the part you can genuinely do yourself with a good pattern and some patience.
