Before diving into maintenance and accessories, let's examine the core specifications of the Optoma HD20 LV. Understanding these specifications is crucial for gauging its performance and suitability for your needs. While precise figures may vary slightly depending on the source, the key specifications typically include:
* Resolution: 1280 x 720 (720p) – This native resolution provides a high-definition picture, suitable for most home theater applications. While not as sharp as 1080p, 720p still offers a significant upgrade over standard definition.
* Brightness: Typically around 2000 lumens – This brightness rating determines how well the projector performs in various ambient light conditions. The HD20 LV is best suited for darkened rooms, as its brightness might be insufficient for brightly lit environments.
* Contrast Ratio: A crucial factor in image quality, the contrast ratio of the HD20 LV usually falls within the range of 1500:1 to 2000:1. This indicates the difference in brightness between the brightest white and the darkest black. Higher contrast ratios generally lead to more vibrant and detailed images.
* Lamp Life: The lifespan of the lamp is a significant consideration for long-term ownership. The Optoma HD20 LV typically boasts a lamp life of approximately 3000-4000 hours in normal mode and even longer in eco mode. This translates to several years of use before requiring a replacement.
* Throw Ratio: This specification determines the projector's placement distance relative to the screen size. The HD20 LV's throw ratio allows for flexible placement options, accommodating various room sizes and screen dimensions. Refer to your Optoma HD20 manual for precise throw ratio details.
* Connectivity: The projector usually features a range of connectivity options including HDMI, VGA, and component video inputs. This allows for connection to various sources such as Blu-ray players, gaming consoles, and computers.
