An article giving some background to LCD monitors appeared in Acorn Publisher magazine (volume 9 issue 1 - Autumn 2002).

The monitors described below are supplied by ExpLAN and the information here, and for the Acorn Publisher article, was supplied by Paul Richardson of ExpLAN. This is not intended as an advert solely for ExpLAN. We want to hear from other suppliers who can confirm their LCD monitors work with RISC OS machines and can supply appropriate MDFs with the monitors. Details of suppliers and prices will be added to the specifications in due course.
