Hi all,
i thought this might help Scrappysphinx, as you can see on the borders there are the "bandind" issues people talk about, but the main image is great, i know people say this is not an aga scandoubler but this picture is AB3D2 and i can't see anything wrong with it :D (lol where's Alexh to tell me i'm wrong? lol)

cheers all, JuvUK

Hey Juv, to be honest i've been using the scandoubler for 2 or 3 days now with a crt monitor and i find it to be as good as my CM8833 monitor.
I have now offered it to imnogeek and am awaiting his reply.
Thanks for the pics though.
Thats what i love about this site, everyone is always so friendly and always there to lend a hand!

Thanks again

@ JuvUK

Those borders are the TFT sizing the Amiga's output. Chain is right about using Copper Gradients. This will show you the real banding issues, but........

....Chuck a CRT on the thing & the Banding will be Gone! - Then come back & ask me why! :wink:

not always my friend, not always.

there are two type of bandings :)
one is color banding on rich color transitions,
and second one (which you probably refer to) is a vertical banding, which occurs with some internal scandoublers and its/occurs probably like moire effect

cheers, JuvUK

it can be also game with copper background, sont know which, just try to figure it out ( it will probably no happen as you cannot compare it with original image)

once you will see it, its like nightmare, be prepared to cool your emotions, really
