Answers: How can I turn an old TV and projector into a high-contrast display using a DIY rear-projection setup?

• DIY television modification
• Rear projection display
• LCD backlight replacement
• Projector brightness and contrast testing
• OBS Studio luma key filter setup

What it concludes

• An old LCD television panel combined with a projector backlight can achieve high-contrast image quality and deep black levels comparable to high-end displays.
• Removing the color wheel from a single-chip DLP projector produces a bright black-and-white image suitable for rear-projecting onto an LCD panel.
• Using OBS Studio with the Luma Key and Glow filters allows for the creation of an accurate luminance map to eliminate blooming on projector-backlit LCD panels.
• Using mirrors to fold the light path enables the use of long-throw projectors directly behind a wall-mounted TV setup.
