In order to perform motion pictures on the displays nowadays, the 2234 Video Pattern Generator has integrated the Multi-Media playback technology to provide versatile motion pictures for display quality evaluation test. It has high resolution test quality and multiple outputs support that can meet the requirements for multimedia video tests such as LCD Monitor / LCD TV / PDP / Projector of today and in the future.
This Video Pattern Generator provides both analog and digital signals, also supports multiple ports for independent output test and multimedia audio/video formats for play application. For the digital signal, the pixel rate of TMDS output is up to 330MHz and the test screen resolution is able to support beyond WQUXGA. Moreover, to cope with the higher frequency signal test for DVI Dual HDCP tests, it also supports dual link DVI test application.
Chroma 2234在最新的高分辨率多媒体数字视频传输界面HDMI V1.3中构建，以提供高速带宽和颜色深度。它支持24、30、36位（RGB或YCBCR）和新的颜色标准XVYCC以及SYCC，Adobe RGB和Adobe YCC（CEA-861E），以实现真实的自然色和高分辨率图像。
DisplayPort是由VESA定义的最新视频输出接口。信号传输主要由主通道，AUX CH和热塞（HPD）组成3种类型的信号。主通道由4个车道（1、2、4车道）形成，每个车道可以支持2.7Gbps或1.62Gbps的传输速率。高达10.8Gbps可以通过4个车道传输。Chroma 2234支持DisplayPort标准格式，具有以下关键功能：
DPCD（DisplayPort配置数据）是DisplayPort的主要功能，它充当源和接收器之间的通信桥。Chroma 2234能够自动或手动连接后自动或手动调整参数。由于在长距离传输期间可能会发生信号衰减以进行DisplayPort，因此还可以调整前重点和秋千电压。
In addition Chroma 2234 supports SSC (Spread Spectrum Clock, the technology to eliminate EMI) test that can significantly reduce the EMI problems occurred among displays and components, and simplify the product design.
For the application of multiple tests, Chroma 2234 supports a variety of audio/video and pattern file formats for play with the resolution up to 1080p. Meanwhile, to fulfill the test application for multi ports output, 3 HDMI and 2 DisplayPorts of which the output settings can be executed separately have been built in to reduce a great deal of test time and finish the tests in the fastest way possible.
用于操作，Chroma 2234采用了全彩色图形界面，并内置内存以存储储存，具有多元化的特殊测试模式，例如XVYCC，HDCP＆E-EDID，8/10/12bit深色，CEC，Lipsync，Lipsync和中国高清测试模式，用于使用。测试可以轻松，快速地执行，以节省时间并控制成本。
遥控器（可选）可用于替换直接面板编辑，以在大型测试区域进行灵活练习。它适用于生产线中的质量应用。此外，可以通过PC站点上的VPG主应用程序编辑各种定时参数和测试模式。Chroma 2234的易操作接口和完整的测试功能适用于R＆D，生产测试和质量保证的所有视频和相关行业。
