- Hi Freaks,
-
- I am using a Multivision Flickerfixer card in my Amiga 2000.
- It supports both PAL and NTSC Mode (I have installed a switch on
- the J102 jumper of my motherboard), but on a Multisync-Monitor
- which is used to operate with 70 Hz or more the Amiga's 60 Hz are
- still to less to build a real flicker-free picture.
- Sold with the card was a programm "SyncMaster II" which programs
- the ECS-Agnus to work with higher Picture Frequency by reducing the
- number of vertical lines. Using full overscan it is possible to have
- 70 Hz with a remaining resolution of 720x400. So far, so good.
-
- My problem: When running with frequencies greater than 60 Hz,
- sometimes the card fails. The effects range from snowstorms on the
- screen to the Amiga-Videosignal displayed twice on the screen with
- interlace-like flickering. These crashes specially occur when I
- open, close, or click-to-front/back screens. At least sometimes
- it's only the card that crashes, for the system continues to run.
- In a few cases I was even able to reset the display by starting
- SyncMaster-program with hotkey.
-
- This seems to be a general problem of the Multivision card, for
- the exchange of the card did not help, or the reason is to be found
- in my motherboard.
-
- - Is there anybody who has the same problem ?
- - Does someone have a Multivision that operates with 70Hz o.k. ?
- - What could be the cause of it ?
- - Are there other Programs that do similar thing to the Agnus on PD ?
- - Is Multivision able to operate with the 2.1-Videomode Euro72 ?
-
- I would be glad if someone could help me to make my Amiga really
- flickerfree.
