When selecting a home theater projector, it's essential to consider various factors, including resolution, contrast ratio, connectivity options, and lumens. Higher resolution projectors offer sharper and more detailed images, while a higher contrast ratio enhances the difference between dark and light areas of the image. Additionally, connectivity options such as HDMI and wireless capabilities allow for easy integration with other devices. You can find the perfect home theater projector for your needs by considering these factors alongside lumens.
