How to deal with vertical black lines

[GeoMan]

Some games when run at a higher resolution produce thin vertical black lines on screen due to scaling.

After some experiment with different values i discovered some Custom res values that remove the vertical lines (they depend on the initial game resolution).

Try the following Custom res:

1365x1365 or 1260x1260

So far, one of these values worked with the games i tried. Probably other values will work too if you want to experiment...

you can add 1200*1600 (inverted)
