Welcome Robertino.

Don't worry too much about your English, if you promise me the Italian won't laugh too hard in my face when I try and speak Italian when I'm over next summer. ;-)

Now to your question. Don't worry too much about the screen being off-center. It's not your Amiga at fault. Your TV-sets should be okay too.

While in workbench, you can try and resolve the problem by playing about with the overscan settings (Sys:/prefs/overscan). It gives the possibility to move the screen around a bit and it also allows you to stretch it a bit to make it fit your tv. Unfortunately, this won't work with the games that don't run from the Workbench. If the picture is off just a few pixels then don't worry about it, while playing games it shouldn't be a big problem.

Well, that's my few cents. If someone has a fix for the non-workbench games I'd love to read it ;-)

Oh... you have already checked for adjustments on the tv?

One comment:  If you move the screen closer than 72 pixels from the left, you will lose some of the sprite graphics capabilities of the chipset.  You shouldn't move the screen to values of less than 72 (48 hexadecimal) with overscan preferences.  Also, don't increase the vertical overscan to a nonstandard value.  640x256 or 640x512 interlaced is normal.

How you do to make the connection? Internal RF modulator? Composite? A520? Other external modulator?:-?

Try the other choices, too.

If everything fails: buy a multisync monitor, or an external scandoubler/flickerfixer (and a VGA monitor), or a VGAbox......:-?

So many options, no money enough for all....... :boohoo:

Do you have a digital camera? It would be easier to understand the problem if you took a picture of it. I know that some games are not centered and is not using the whole tv screen.
