Psone screen inputting luma instead of c-sync.

I already posted this along with another question in another thread. But I think it deserved it's own thread in a proper forum. So ya.

I heard you can input luma instead of c-sync on a psone screen. Is this true.

Thanks,

Jeroen

no i think the alternate sync would be to use composite, if you used luma you might get a reddish tint i think

It should work fine. Luma contains c-sync and brightness information. The PSone LCD has a LM1881 sync separator which will just leave the c-sync. I tried it myself with a N64, worked fine.

If it has a sync seperator.....would composite work to?
(not sure if this particular sync seperator can handle the extra info (it should))

edit: phantom you realise what you said doesn't make a lot of sense. Do you?

for some reason i thought luma was red + sync so then if you had rgb+rc then youd have 2r... i iz stupidz sometimez
