* When you have a slightly bent edge of the upper half of the display area, you can correct the problem by slightly changing C21. I had the best result with 6.8nF, so you will probably have a good picture with it as well, if you used the same ICs. If the picture is slightly off, just experiment a little with C21. (in the 4.7-10nF area)
