Indivision and non-interlace PAL question

[larsef]

Hi.
I have an Amiga 1200 which is connected to my SVGA screen (using MultiScan mode), and this is working fine but I'm getting tired of the screen going off-sync everytime I start a program which wants to open a non-interlace PAL screen. This of course includes most games and demos. Thus, I've been looking at a scan-doubler such as the Indivision. I read somewhere that the image is not perfect for non-interlace PAL-mode, but I would like to know in what way. I have a CRT screen which can go down as low as 50 Hz/31 KHz.

Anyone here that has any experience in using the Indivision in non-interlace PAL-mode (i.e. native screen mode when starting an Amiga from Europe)? I understand that it is easier to get good quality in NTSC mode, but I'm only interested in PAL. Is the quality bad and in what way?

Thanks,
Lars

There is no difference between interlaced and non-interlaced regarding quality from the Indivision's point of view. In non-interlaced simply every row is displayed twice, in interlace mode one picture is stored and when the second picture is transmitted, the lines from the first picture are put in between the lines of the second picture, just like it should be.

However, the overall quality of the Indivision is worse than a direct connection using MultiScan screen mode.

Bye,

In what way is the quality worse? Bad colours, bad contrast, blurred image? The Indivision is suppose to just pass the signal through without doing anything if the signal is already MultiScan. Do you mean that the MultiScan signal gets worse than passed through Indivision?

Thanks,
