If the Amiga dictate the clockrate it will be cycle exact, because the Amiga defines it.
And most TV sets use HDMI, better get started with it. Or the video output options might be as limited as trying to read 5,25" floppys.


simpler get a TV with SCART, or convert RGB to YPbPr (think EAB has such project).
iirc, the HDMI thing wouldn't work because Amiga does D/A conversion inside a chip.
so you'd need to do a A/D conversion for HDMI, and that sux, and most TVs can do that with component signal already.
Better sorry than worry.

@kvasir
better look for RGB->HDMI

@frekmax
right, and if you had thoroughly read the thread, you'd know how to build one yourself (by now) :P

I have a SCART Adaptor where i can put the Red-White-Yellow cable from the Amiga into, and then i can put it in the SCART on my TV. Will that give me better picture quality or is it still not real SCART?


you need to check if that SCART connector on TV can take RGB signal. some TVs have more than one SCART. look in the manual. there is pinout for making 'RGB cable' on EAB.
Better sorry than worry.

I have 2 SCART to Amiga RGB Cables but when i use them on my 43 inch plasma screen, i get worse picture than when i use Composite cable. I find that very strange


are you sure TV is in 'RGB' mode? I suggest you build this one:

Hi do you mean there are something i need to change in my TV settings?


well, it depends. some old TVs let you select RGB/S-Video/Composite on the remote with AV button. but nowadays, you probably need good cable that supplies enough voltage on (infamous) pin 16 of SCART connector ( http://en.wikipedia.org/wiki/Scart ) so that TV automagically switches to RGB. other than that, you might need some resistors in signal lines. check out that thread.
Better sorry than worry.
