Using the Avia crosshatch patter (inverse mode) --- the vertical and horizontal lines that make up the "checkerboard" look should be entirely straight. Now, I know my overscan was corrected a bit --- as a result, the lines near the edges show more bending which is one of the flaws on my set. However, there is some slight bend in some of the lines around the ceenter of the crosshatch pattern. I don't notice any distortion when I watch movies, etc., but is this something I should try to correct. I've also been making convergence tweaks here and there every so often so this might be part of the problem. What are your thoughts about this?
