Life at home will be more enjoyable if you have a COOAU projector. Why do we need to purchase a projector? The projector can easily project a 100-inch screen, and it can be adjusted if you need it bigger. A TV of the same size will be much more expensive. The projector can be used without a screen, you can project it onto any flat white wall, and it can easily be moved to places like your living room, garage, or patio. Using a projector saves you the trouble of installing it on the wall and saves space. This way you can use it anywhere without having to be fixed somewhere. A bigger screen brings you a better viewing experience! More cost-effective, larger eye protection screens and multi-functional advantages make projectors a better buy than TVs. Next, let's learn more about the COOAU YG431 video projector. Easier way to connect. Using a projector can project images or videos onto a screen or wall. First, you need to connect to our mobile phone, computer, DVD and other devices to enlarge the image on the small screen. Our YG431 projector is equipped with 2 USB sockets, 1 HDMI socket, 1 3.5mm audio cable socket, and 1 AV socket, which is convenient for you to connect to any device you want to use. (One of the USB sockets supports the use of the original iOS data cable to directly connect the iOS phone for screen mirroring without an additional HDMI converter. Android phone needs to use HDMI converter.) But we need to use the projector more conveniently and save the trouble of connecting multiple data cables. Our YG431 projector supports 5G/2.4G WiFi and 5.1 Bluetooth , which means no need to plug in the data cable, You can connect iPhone, Android phone, laptop, ipad and other wireless devices through WiFi. You can connect bluetooth speakers and bluetooth headphones via bluetooth. This can meet your different playback needs and can be easily moved to any place. You can build a home theater by connecting WiFi and Bluetooth. High Quality Experience. When choosing a projector, the parameters to pay attention to are resolution and brightness. Our YG431 has a real resolution of 1920*1080p. Most of other projectors are 720p or support 1080p. The higher the resolution, the clearer the projected picture under the same picture size. The brightness of our YG431 is 220ANSI which is more professional. (ANSI lumens is a method of measuring projector luminous flux developed by the American National Standards Institute). The higher the brightness of the projector, the brighter the projected picture will be under the same picture size. Among projectors of the same size, our YG431 will perform better. The precision parts inside are also very important: * In the design, we used a compact shell, which has a more refined appearance and a better overall texture. * The high-speed cooling fan can cool down more quickly while meeting the requirement of mute, and the machine can also maintain a stable state during long-term playback, so that movie enjoyment will not be disturbed. * The three-layer lens doubles the clarity of the projected image, and the casing is sealed to prevent dust from entering the projected image. * Excellent LED bulbs, improve the brightness of the projection, and at the same time have a longer service life and will not be easily damaged. If you encounter some problems, let us know and we will deal with them quickly. The thoughtful design is much more than that. Large Focus Button As we all know, the clarity of the projector screen is very important. This design is more convenient to operate than other small buttons in order to adjust the focus accurately. Height Adjustable Height can be adjusted. If you need it, you can adjust this position, adjust the image to a height that is comfortable for you. It can be hidden when not needed. Support Ceiling Installation There is a 1/4" hole on the bottom of the projector. It will be used if you need to fix the projector to a tripod or install it on the ceiling. Support Dolby Audio The projector supports decoding Dolby audio. If you have higher sound quality requirements, you can connect a Dolby speaker to experience the auditory enjoyment like a theater.
