BloodyHell619 This is an interesting and rather sad post. It makes it clear that none of the dithering disabling tweaks and apps will disable it. This is probably why NVIDIA refuses to admit the card is doing dithering. It could be that it's not even fixable with a driver.
I have seen that post before, and I don't think that simplification is entirely accurate, but it's more complex than a simple "yes/no" question.
