Maximize Image Quality (and ROI) with Projection

Posted on 8/25/2019 7:00:00 PM by Da-Lite Team



Every type of display technology has special concerns: Glare from flat panels diminish image quality in high ambient light areas, LED panels are costly and heavy. Two-piece projection has its own unique considerations; however, there are easy ways to maximize image quality. We’ll cover a few as we continue exploring how to correctly pair projectors and projection screens. If you missed part one, you can find it here.

Tension

In projection, tension plays a very important and positive role in producing the best image possible. A tensioned screen will keep the projection surface under constant vertical and horizontal tensioning for a perfectly flat viewing area. The new TruGuide™ Electric Screen Tensioning System will keep the surface flat and prevents waves, edge-curling and ripples that allow pixels to disappear and degrade image quality.

Controlling Color & Brightness

Improperly paired projectors and screens can also sometimes introduce artifacts into an image. Two such examples are hotspots and color shifts. Hotspots occur when images are brighter in the middle of the screen than at the sides. This usually occurs when the gain of the screen, the amount of light projected off the screen to the viewer, isn’t well-matched to the projector. Color shifts, when colors look different depending on where the viewer is seated, happen for similar reasons.

Da-Lite high-resolution surfaces, like HD Progressive, ensure an even distribution of projected light for ideal image uniformity. The projected light will look evenly bright on any area of the projection screen to create a well-illuminated and detailed image for the audience. Da-Lite surfaces are also tested and color measured to preserve the true color of the projector.

Important Intangibles

Complete happiness with image quality sometimes comes with a bit of sticker shock. We often forget that price includes essential services beyond the screen itself, like assurances in long-term support and contributing to healthier work and living spaces.
