Thanks Invizm for your quick and clear reply. I can certainly act as the lowest common denominator - if i understand it, it means everyone will . That is good news and cannot wait for this. Will order as soon as they are available.If you think this, then probably a lot of other people do too - so thanks for feedback, I should probably put an explanation somewhere somehow.Invzim - thanks for the update. Looks great and cannot wait to order a few (maybe in time for Christmas?). One question : it looks like the sync output is TTL, i understood this to be bad for LCD monitors. Is there an option to attenuate this to bring it down to safe levels so i can use a LCD monitor (would be connecting via VGA port on the monitor).... Or have i misunderstood (perfectly possible)? ThanksBatsugun is un-fixable, unfortunately - and was a bit of a curve-ball so I had to re-write a lot of the code. On the plus side, the refactor made things a bit simpler and more stable.
I made a page on what the scaler does with a few details here, which will hopefully make things a little clearer what the scaler is and what it's not:

VGA has 5V sync, which is often called TTL - so this is 100% standard VGA sync and will pose no issues with LCD's.
