I’m sure most technicians have experienced the challenges of hooking up external display devices to laptops, media servers, projectors, plasma / LCD screens, scalars, matrix switchers, and other devices which have video cards. You know are certain beyond doubt the output of your video source works. Yet, the display isn’t recognized by the video card. This is not uncommon and becomes very frustrating especially when timelines and pressures mount just before a show.
So why does this happen? Simply put, the computer graphics card must be able to see the device that it is hooked up to. Unless there is communication between the two devices the display will not engage.
The solution for ColossoVision was purchasing DVI Parrot EDID ( Extended Display Identification Data ) emulators designed by Carallon. Parrots are now a part of our standard component/accessories for all of our LED display rentals. They are simple to use and blessing to have at a show. One of the key features we like is the “Trainer Software” which can be used on Macs and Windows operating systems. A totally user friendly and configureable EDID management tool. “The Trainer software allows the capture, editing, and saving of EDID data for multiple Parrots, making it ideal for systems with numerous graphics cards connected to various DVI devices. The custom settings, once captured, can be permanently saved, e-mailed as attachments, etc. The Parrot Trainer Software allows adjustment of all EDID settings, including resolution, video timing, etc.”
The best part of going to a venue / show is telling our clients we’re also bringing some trainable parrots with us.
