目前DTS公司已经发布2017年第21版DTS演示碟，内含数量众多的DTS X演示片段，并且首次提供了普通BD版本和4K UHD版本两张盘片。下面就为大家介绍最新的第21版DTS演示碟。
图中左边蓝色是单面单层的 BD-25 Blu-ray 碟，而另一只红色丝印的就是单面双层的 4K UHD BD-66
DTS 每一年都会出一版DTS最新音效的测试碟，制作本系列光盘的目的是在全球推广和使用 dts技术，并不对外发售。所以市场上是无法买到该系列光盘的。2017年版本很特别，大手笔制作了4K UHD BD+BD双版本，UHD BD部分收录了12段电影精彩片段，全都以dts:X 音效收录制作。BD部分除了电影片段之外，也加入了不少音乐测试片段。
在DTS演示碟当中，除了精选的电影音效部分都非常具有展示火力效果之外，更特别的是，电影展示片段的画面部分全都带有HDR，影像与声音都非常完美，根本就是令玩家们疯狂的一部完美影音测试光盘。
▲《X战警：天启》这碟一共在 X-Men: Apocalypse 有两个选段，第二段是尾场的打斗场面，这里可有激列的战斗场面可以感受到，发挥DTS-HD MA 7.1 效果
▲《绝地孤军》则属 4K UHD BD 版独有片段，环绕声着重呈现军机上空盘旋及子弹扫射效果，能突显 DTS:X 这种三维物件导向环绕声的优点
▲ 同样是以内容吸引我，这是一段讲述配音的内容，有会心微笑的效果，同样是播这碟时不要错过播出的片段之一
▲ 其他非电影片段，《Nightlight》集合了常见电影中的声音特效，可以体验到 DTS:X 的三维效果及声音移向
