Hi, I’m getting glicthes on the video sometimes. Games seem to be OK, but its quite bad on demos.

I’ve checked previous posts of similar issues but they were with different model Amigas and looked to be Denise related.

Any suggestions please?

Can you please run a SysInfo screen if glitches are even more persistent ?
At least I found that in my (A500++) setup. Denise under heavy suspicion, too.

Hi,

I’ve tried Sysinfo and there are no glitches. I’ve tried a few more games and they are glitch free too.

It seems just a few demos cause these glitches when viewed via the ZZ9000. If I view the same demos through the RGB port, they are glitch free.

Thnx. Hope you get clues from others, too.
