its hard to see in a picture…ive tried to capture it via my mobile phone…but its not east to see…1.9seconds into this video…

Hi, I see what you mean. It seems to appear when your harddisk or other storage is active? I think it is electromagnetic interference from your storage hardware. What do you use? A harddisk or some kind of SD card adapter?

yes…there is a lot of upgrades…I was using a TF536 with updated firmware…still the same effect…I`m now using a Relocated PiStorm…both of these use a SD card…maybe its the cable from the Denice Adapter thats long(A2000…?)

Guess there is no fix for this as it`s been 9 days since the first post…?

looks like i will have to use a Duel monitor setup and a RGBtoHDMI adapter.

I have not tried the Denise adapter in A2000. The system is designed to use the videoslot adapter in A2000. Does that behave differently? Also, what if you remove all but the bare minimum of upgrades? It is hard for me to diagnose problems like this remotely, because everybody’s setup is unique. You will have to do some research and testing yourself. Some people had success with a ferrite clamps for the flat cable, but I’m not sure if they would help in your case. If you’re interested, i can post the product name/model numbers.

I dont know as i dont own a A2000…the sparkle effect is the same with…the 68000 cpu…TF536…Pistorm

Ah, I’m very sorry, I misunderstood the Amiga model you have. Do you have another A500 to compare maybe?
