Hmm. Interesting. Looks like I'll have to revise my screen setup. It's a Samsung LED device with HDMI input. This box outputs HDMI too, but the other boxes I use it on output DVI, so by piecemeal development I've ended up with a four-port DVI switch, all connected with adapter cables. It seems likely that EDID is getting lost, and I may now also have a reason for the washed-out appearance of the screen. Modern websites with their pale colours are hard to read. Even the green of KMail's quoted text is hard. The other boxes I mentioned can also output VGA, and the screen can accept VGA too and switch between inputs. So I just need a two-port VGA switch and some cables. I've not long since thrown out all the old VGA stuff - damn! I knew I should never throw anything away. Thanks for your help. -- Regards, Peter.
