Sync issues over Component video output?

Unread post by redsteakraw »

So I recently went to try some of the NES homebrew / demos and ran the fireworks demo. When the fireworks burst and there is a white flash my TV loses sync and the screen rolls. I am using the IO Board and have a dsub to component adapter hooked up to a late model consumer CRT tv with component input. I did notice this also on the NeoGeo core with king of fighters when the screen flashes white. Is this something anyone else noticed? I am trying to figure out if is my TV, adaptor, core or hardware problem. I am not using any CRT effects or scaling. Can anyone replicate this with the fireworks demo?

Sounds like your sync level is too high for your CRT. Does it do this with any other input?

A bright white screen will be the highest the voltage will get so that's why it's probably going out of range but otherwise ok.

Another console or DVD or something that does the same would help to narrow it down to the MiSTer output or not.

So far I haven't found a good alternate test case.
