Sharpness setting has a pretty dramatic effect, especially on SD content
Today, after finally getting the 70" Visio up on the wall above my mantle, I changed the Directv HDMI cable from HDMI4 to HDMI1. Since I had not used the HDMI 1 connection before today, the settings were at defaults. I immediately noticed that there was a signicant degradation in picture quality vs the calibrated HDMI4 port.
What was surprising to me was how much the default sharpness setting appeared to break up the image.
The order in which I did the settings left the sharpness setting until last. While tweaking that setting, I took these before/after pics. There was a substantial difference between the default 50 sharpness setting and no sharpness as you can hopefully see below.
Here is the screenshot of CNN HD during the Erin Burnett program tonight:
And here is the same shot at 0 sharpness
The pics don't fully convey it (click to enlarge them for more detail) but to my eyes, the 50 sharpness begins to introduce significant artifacts into the image. For example, the image appears to break up beginning at settings as low as 20 and its very noticeable at 50 and above.
I've found that a setting of about 15 sharpness yields the best balance to introduce just the right amount of sharpness without introducing artifacts.
