Bill, When it comes to understanding/using professional video on LCD panels there's only one engineer, personally, that I turn to. His name is Mike Boland and his company Boland Communications, www.bolandcom.com, is on the forefront when it comes to working with video/LCD technology. If you need answers by tomorrow you could give him a call on his cellphone, (714) 747-9090. Tell him what you're working on and tell him that I recommended you give him a call. If anbody can provide answers (and solutions) it's Mike. Bart P.S. Tell him I said hi !! - - - - - - - - - - - - - - - Bart Harrison MPA - The HD Suite HD Editing Systems, Consulting, Production & Post, Exhibition & Distribution www.hdsuite.com 954-894-1221 At 09:48 PM 6/8/2004 +0000, you wrote: >I basically agree with you except this customer ( a major airplane maker) >is trying to put component inputs onto an a/c that uses CRT and composite >and will use LCD to replace the CRT and upgrade to component distribution >to the LCDS.
