As well, when you are scanning too close to the edges of the tubes screen, the scanning becomes non linear. the rectangle of the picture then gets the shape of a pillow or a barrel. This is also called "pillow distortion" and "barrel distortion".
So it is not unwise that the corners of the picture are free of the edges of the picture tube.
On the Grant Dixon test picture you might use a ruler to make the circle a true circle..... Grant calculated it to be a circle.
You will see that this picture has a vertical grey scale at the left and at the right. This grey scale is two lines at both sides. If your frame sync is delayed you will see a wider grey scale at the left side (two lines) and a narrower (one line) at the right side.
Good luck..... It is amazing
HI Klaas
i tried this size i think this is about tops before the bending would happen as you and Steve mentioned in hes post also ...I will try your ruler a compass for making circles also do the trick careful not touching the screen with the pointy bit ! the eyes pretty good noticing how off it is but yes a correct measurements do need a tool. Heres a few gos i had this afternoon for fun trying the maximum size i think is usable for the 3BP1.
