![]() Low contrast ratios can cause images to look flat, ill-defined and lifeless. Higher contrast ratios allow an image to have greater detail, atmosphere and realism. A contrast ratio of 3000:1 means that the brightest whites of an image are 3000 times brighter than the darkest blacks. The contrast ratio measures the ratio between the brightest elements of an image and the darkest. However, when coupled with enough lumens and a deep enough contrast, 720p can still produce an immersive and engaging image quality. While full-HD 1080p and 4K UHD devices are available, budget projectors are typically limited to 720p. The more there are, the more precise an image will be. Resolution refers to the number of pixels a projector can display. Some lumens reported on budget projectors are not tested to the ANSI standard and may be inaccurate - we’ve highlighted any instances of this in our selection below. Standardised by the American National Standards Institute, the acronym 'ANSI' should follow any lumen measurement: for example, 1000 ANSI lumens. Larger rooms and brightly lit areas require upwards of 2000 lumens ANSI. A bright sunny day is 100,000 lumens.Ī projector with between 200-500 lumens ANSI will be right for living rooms and smaller spaces with limited ambient lighting. As a point of reference, ViewSonic report that a candle sits around 14 lumens, while a sunset comes in at 400 lumens. What we look for in the best budget projectors: LumensĪ lumen is a measurement of light, indicating the brightness of a light source.
