Hi all.
Looking for some advice/assistance. I've revitalised my A4000D, and in the process I've added in my old Picasso IV card. It is fitted to the bottom-most slot (aligning with the A4K video slot) and its integrated flicker fixer which has been separated from the main board (since the time it was used with my old A2K) is fitted to the inline video slot and attached to the PIV via its original ribbon cables... so far, all appears to be working well... however:
It's displaying RTG screens fine through its VGA socket on my Thinkvision LCD (1152x980 res, unfortunately other resolutions are out of range for my monitor it appears).
However I'm having issues when I switch screen modes to any of the native Amiga modes (eg Pal or NTSC low-, high- or interlaced high-res modes).
The resultant output via the PIV's VGA has a decidedly "green" flavour, and also displays distinct vertical "bars" on the screen.
The native modes display fine on my 1084 monitor which is concurrently connected to the A4K's 23 pin RGB output. Obviously I would like all modes to work correctly (if possible) via the PIV's VGA output.
I've attached some images showing the "faulty" native mode output via VGA , the equivalent 1084 display (pardon the shadowing caused by the photography, the output here is perfect, even if the photo isn't), and thirdly the VGA output in all its 1152x980 24 bit glory!
Any advice or help here would be much appreciated.
The A4K is a 68040 with 128Mb of Z3 ram +2Mb chip and no onboard fast ram simms...
