Projector Warmup / Run-In Cycle

Free fullscreen run-in / warmup cycle for new projectors. Auto-cycles solid colour fields (R/G/B/C/M/Y/W/K), grayscale ramps, scrolling checkerboards, sine-wave colour washes and (in aggressive mode) RGB strobing and pixel noise — designed to drive panels through their full operating range and equalise response over a multi-hour session. Three modes: standard (10 phases × 60 s), aggressive (12 phases × 30 s, includes strobe + noise), gentle (4 phases × 120 s, smoother).

How to use

1
Set duration

4 hours is a good first session for a new projector. Repeat over several days for full run-in (50–200 hours total).

2
Pick mode

Standard for most cases. Gentle if your projector's fan gets loud on aggressive content.

3
Start fullscreen

The browser asks for fullscreen — accept. Screen never sleeps because content updates each frame.

4
Walk away

Cycle runs unattended. Phase and remaining time appear briefly when you mouse over.

Unattended run-in cycle for new LCD and DLP panels

New 3LCD and DLP projectors benefit from 50–200 hours of varied content to equalise panel response. This cycle compresses that into an unattended overnight session. Run in a dim room with adequate ventilation. Press Esc to abort.

FAQ

Why run in a new projector?

3LCD panels and DLP DMD chips have small but measurable response variations across pixels when new. Running varied content for 50–200 hours equalises this — visible improvements in uniformity and colour stability are common.

Can I run this on a laser projector?

Lasers have no panels to equalise — a run-in is unnecessary. But the cycle is still useful for general dead-pixel checking or to verify all colour transitions render correctly on a fresh unit.

Will this damage my projector?

No. The cycle uses normal projection levels — same as watching content. Just ensure adequate ventilation; don't cover the projector.
