Not exactly.The only explanation I have is, that somehow the SCART norm expects low resolution RGB signal and cuts-off everything else - including part of my QL screen.
PAL TV (even connected via RGB) is intended to work in "TV" mode of the QL.So the first question is whether anyone has an explanation why is it so and more importantly if there is a workaround (modifying the Monitor / TV (I remember we were doing so with the CRTs, but can one do that also with LCD?
