Story tells that it is cheaper to make monitors (and TeeVees) that have the both scan rates. Anyway, I think it is sufficient that the line frequency is the same 15625 Hz. ECSTest tests the "TEST" signal which is grounded for NTSC machines, it doesn't check for video modes. -- Pekka Pessi ppessi@niksula.hut.fi Puh. (90) 455 4757 JT 11E122, 02150 Espoo
