On reflection, I think that BBC trial I mentioned, may have been about colour on 405 lines [which I do agree was a very durable b+w standard]. You only have to look at the [properly set up] 405 line sets Mike Barker exhibits regularly at Golborne to see how really very good it can be. The erudite comments about loss of definition when a larger screen is used [ie beyond the regular CRT sizes] perhaps go a long way towards answering my frequent question-Why didn't we just go ahead into colour with 405? On the other hand, apart from the international compatibility issue, there would have been no real concept of what future screen sizes might be, at the time, despite Baird's work back in the thirties.
