&lt;p&gt;The Evanesce Tab-Tension is a versatile in-ceiling projection screen that conveniently disappears from view when not in use. It can be installed from within the above-ceiling airspace or from below thanks to its removable base panels that were originally designed for the European market. Its award-winning CineWhite? 1.1 gain matte white tensioned-material provides superb color temperature with wide diffusion uniformity. The screen is moved by a strong fast-acting tubular motor and comes with a full IR/RF wireless 12-volt trigger and Ethernet control package.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt; Screen Material &lt;/strong&gt;&lt;br /&gt;&amp;bull; CineWhite? 1.1 Gain black backed matte white screen material&lt;br /&gt;&amp;bull; 180? wide-viewing angle&lt;br /&gt;&amp;bull; 4K Ultra HD Active 3D and HDR Ready&lt;br /&gt;&amp;bull; Tab-tension cords provide uniform flatness on entire projection surface&lt;br /&gt;&lt;br /&gt;&lt;strong&gt; Design and installation &lt;/strong&gt;&lt;br /&gt;&amp;bull; Disappearing recessed in-ceiling design for non-dedicated media rooms&lt;br /&gt;&amp;bull; Aluminum housing with white finish (RAL9003) is strong and moisture resistant&lt;br /&gt;&amp;bull; Integrated ceiling projection screen ships fully assembled ready to install&lt;br /&gt;&amp;bull; Installation kit included for above or below ceiling&lt;br /&gt;&lt;br /&gt;&lt;strong&gt; Control system &lt;/strong&gt;&lt;br /&gt;&amp;bull; Internal Radio Frequency/Infrared receivers with IR RF remotes included&lt;br /&gt;&amp;bull; Low voltage 3-way wall switch and in-wall RJ45 module included&lt;br /&gt;&amp;bull; Standard 5-12 volt trigger to synchronize screen operation with the projector&amp;#039;s power cycle&lt;/p&gt;&lt;table class=features&gt;&lt;thead&gt;&lt;tr&gt;&lt;th colspan=2&gt;Features&lt;/th&gt;&lt;/tr&gt;&lt;/thead&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td class=feature&gt;Screen Type&lt;/td&gt;&lt;td&gt;Electric Tab Tensioned  &lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=feature&gt;Diagonal Screen Size (inch)&lt;/td&gt;&lt;td&gt;108  &lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=feature&gt;Viewing Area (WxH) cm&lt;/td&gt;&lt;td&gt;235 x 147  &lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=feature&gt;Format&lt;/td&gt;&lt;td&gt;16:10  &lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;
