My 1200 tower is hooked up to my flat screen through RGB on Amiga side and Scart lead on the other end. Works ok for games - not very good for applications because I haven't got a flickerfixer on it.
My 4000D is hooked up to a PC flatscreen monitor for applications through a graphics card and to a portable tv for games in the same way as my 1200 tower.
Not the best way of doing things but it works for me :lol:
