These projectors are compact and light weight, produce high quality images, and help you get the most out of your presentations. Ultra short throw projectors are located very close to the screen, less than 2 feet from the screen to be precise. So, not only can you enjoy the big screen experience in a smaller room, but also helps avoid obstructions, like people walking in and out of the room. With an excellent design, great performance, easy installation, and low cost, these projectors work great. Plus, they offer optimum flexibility of use as they come with optional wireless networking options. If you require a brighter projector and have limited space, UST projectors are your best bet. Here are a few things to keep in mind when **[using ultra short throw projectors](https://www.c3itxperts.com/epson-ultra-short-throw-projectors)** - - **Diffuse reflectors** One of the most important things while choosing a screen for a UST projector is that the surface should be a “full diffusor”. This means that the light from the most distant angles is diffused to the viewer. Viewing surfaces which have mirror-like reflection will reflect a part of the projector light away from the viewer, and hence should not be used. - **Prevent hot-spotting** “Hot spot” is an area on the screen which shines much brighter than the rest of the screen. A hot spot will create a shiny part like a ball of light on the screen. It is caused due to reflection of light from the projector lens, and can cause a big problem as UST projectors are installed very close to the viewing surface. In order to prevent hot-spotting, avoid using high gain viewing surfaces with UST projectors. To prevent hot-spotting, it is best to use a surface with a gain value of 1.0 or lower. - **Flat is best** When using ultra short throw projectors, flatness is even more important than usual. As the projector is so close to the screen, even the smallest waves or wrinkles are enough to create greater distortion, because the angle is much wider. Plus, the lenses used in smaller UST projectors don’t have good focus uniformity, and so they don’t always have the best geometry. Due to this, it is advised that you use only tab-tension or fixed frame screens with UST projectors. - **Screen surface uniformity** Another important factor to consider when using UST projection is the screen surface uniformity. Again, the proximity of the projector to the viewing surface makes it easy to spot the differences in performance from one part of the screen to another. Hence, in order to get the best performance out of your projector, use premium surfaces designed for maximum uniformity. [Ultra short throw projectors](https://www.c3itxperts.com/blog/the-latest-ultra-short-throw-projectors-launched-in-india/) are ideal for interactive presentations, in classrooms and small meeting rooms, as these projectors are ideal for pairing with digital whiteboards. But, when you install UST projectors, keep these points in mind to get the most out of your projector. - [UST projectors](https://www.c3itxperts.com/blog/tag/ust-projectors), - [ultra short throw projector](https://www.c3itxperts.com/blog/tag/ultra-short-throw-projector), - [Business](https://www.c3itxperts.com/blog/tag/business) ##### [← Boosting Sales with Interactive Flat Panel Displays in Retail and More](https://www.c3itxperts.com/blog/ways-to-use-interactive-flat-panel-displays-to-boost-sales) ##### [Guide to the 3 Best Printers for Daily Use →](https://www.c3itxperts.com/blog/guide-to-the-3-best-printers-for-daily-use) 🚨 Free Resource for School Leaders ### The SMART Classroom Reset Guide A practical blueprint to eliminate daily friction and help teachers actually use interactive panels in class.
