Getting the highest quality in screen sharing!
In the Screen Sharing View menu, there are two possibilities, "Adaptive Quality" or "Full Quality". I was on Adaptive Quality by default and I left it there for a while because it means that it is supposed to adapt to the quantity of bandwidth available. The quality of the image I was getting was far from perfect however. I assume it was because my network was not fast enough. After a while, I took the time of trying "Full Quality". The improvement was incredible. Best of all, on a fast wireless n network like I have, there was no lag! So if you are on a fast network, switching to Full Quality is a great improvement.
