sharpness, select Sharpness from the Picture menu and press ENTER. On your external test
pattern source, select a pattern like the one shown in
Figure 4-5. Adjust as needed, looking

“sweep” patterns at the top and bottom. Lower the sharpness setting to eliminate them.

selected. (The input position settings are saved for each input and
