The images below show our computer-based, audio/video hardware and software evaluators. A description of our home-based evaluator system is here.
Audio system comprised of:
Other equipment and accessories used with the PC-based system:
All monitors' gray scale, among other parameters, were calibrated to D6500 using the ColorVision SpyderPRO color analyzer and the Digital Video Essentials and Avia DVDs.
The self-built computer is our main video-quality-assessing evaluator. Why did we build it ourselves? Quite simply, there was nothing available on the market that could come anywhere near the performance level we wanted...well, nothing less than $5,000. High-performance is a critical issue when it comes to playing back PC-based high-definition programming, such as Microsoft's WMV-HD in 1080p mode. On this PC, we have deliberately installed a minimum of software -- i.e. only the essentials -- to keep the video applications (software DVD players) running smooth. This includes the non-usage of virus protection (the unit is almost always "un-networked").
The PC drives are defragmented regularly, and all components' drivers and firmware are updated when a new/improved versions become available. This PC is almost exclusively used for audio and video tests.

On the right: Dell Inspirion 5100, coupled to an EIZO 14" LCD monitor (the laptop's own display panel is not used).
