The A9S LCD Projector
a9s LCD projector offers high brightness and improved ergonomic design, making it ideal for educational and business environments. It has a number of user-friendly features and is fairly inexpensive for its class.
Colors look incredibly rich and natural in Cinema mode. Skin tones have a slight rosiness that adds realism.
Colors
The colors available on an a9s LCD projector are vibrant and detailed, making it perfect for watching movies or playing video games. It also supports 4K resolution, so you can enjoy the latest high-definition content. The projector’s premium HD LCD screen features P3 wide color scale and OriTone perfect color representation, so you can see vivid images with accurate colors. The a9s has a higher contrast ratio than most other projectors, so it can display blacker blacks with stunning clarity.
Unlike most TVs, the a9s can show PC gaming content with low input lag when using either the ‘Game’ or ‘Graphics’ picture mode. It also supports HDMI Enhanced Format, which displays Chroma 4:4:4, so you can see accurate text.
The a9s uses liquid-crystal technology (LCD), which is a popular choice for home and business use. Two technologies have been vying for the home projection market – micromirrors and liquid-crystal displays (LCD). Both have their strengths and weaknesses, but both can deliver excellent image quality. In addition to the resolution and brightness of an LCD projector, its contrast ratio is also important.
Brightness
The brightness of an LCD projector is measured in candela per square meter (cd/m2). Higher cd/m2 levels allow for a larger image size and a brighter image. HDR (High Dynamic Range) is a standard that increases the contrast ratio and color palette, resulting in deeper and more detailed images.
An a9s LCD projector can be used for a variety of applications including business & education, home theater setup and more. Its high resolution of 1080P and LCD LED technology deliver a crystal-clear picture, even on a large screen.
With native 1920×1080 resolution and 4K support plus 800 ANSI lumens of bright image, you can enjoy your favorite a9s LCD projector movies on a big screen in daylight without the fear of light interference. The premium HD LCD screen with P3 wide color scale and OriTone perfect color representation delivers brilliant and rich picture quality, while the MEMC technology eliminates jittery playback for clear and smooth image. The inorganic imaging engine is optimized for long term use and the self-advancing cartridge air filter reduces maintenance. It also supports most professional input configurations including DVI-D, component and S-Video, with assignable audio inputs for “audio follows video” switching.
Contrast
The contrast of a projector measures how much white and black it can put on the screen at the same time. Higher contrast means better blacks and more detail in the image. Look for a projector with a high contrast ratio to get the most detailed, crystal-clear images.
You should also avoid being swayed by inflated native contrast ratios, which aren’t accurate measurements of the projector’s actual contrast capabilities. Instead, look for a projector with an ANSI (ANSi Contrast) rating, which is an actual measurement of the projector’s ability to show BOTH black and white on the screen at the same time considering internal lens light loss/scatter.
The ANSI contrast is the only true measure of a projector’s contrast span during a movie. Those inflated “sequential” contrast numbers referenced by manufacturers measure the screen’s ability to show a 100% IRE white screen pattern first and then the 100% IRE black screen pattern second, not both at the same time as the ANSI value does. These high home theater projector sequential numbers don’t even come close to a projector’s real capability in a room theatre environment with ambient light.
Viewing Angles
With a standard resolution of 1080p and LCD LED technology, this projector delivers crisp and vibrant images for your business presentation, classroom presentation or home theater setup. With a high contrast ratio of 5000:1, the image will remain sharp and clear even when viewed from a distance.
Viewing angles are a crucial consideration when choosing a home theater screen or seating arrangement. The optimal viewing angle converges around the center of the screen where SMPTE, THX and 20th Century Fox recommendations meet with CEDIA guidelines at 43 degrees for 2.4:1 Cinemascope content. This puts the viewers eyes at 1/3rd to 1/6th of screen height which is close to the recommendation of new cinemas built with THX spec at 38 degrees. As screen size and seating arrangements change the viewing angle will move angularly rather than horizontally, so it is important to take this into account when planning your home theater system.
Sound
The dual 5 watt speakers in the A9S are quite good. They play loud without distortion and sound very natural with no timbre changes as volume increases, which isn’t always the case with TVs that claim to be able to act as center speakers in an AVR-based home theater system.
The A9S is also a big step up from the CX in terms of audio quality. This is probably due to the fact that it uses Sony’s Sound Field Optimization feature, which calibrates the soundfield by using built-in microphones to measure the room’s height, speaker distance and location and then synthesizes a surround sound field from real and phantom sounds.
When it comes to gaming, the A9S is a strong contender thanks to its low input lag and support for HDMI Enhanced Format. It can be used with a PC as long as you choose the ‘Game,’ or ‘Graphics’ picture mode and set the video output to ‘PC’ instead of ‘TV’. This will avoid tearing and artifacts that can sometimes occur with some projectors when they are set to ‘TV’ mode.
