Rotating Monitor - Convergence / Purity changes?
« on: May 01, 2006, 12:09:49 am »
Just curious what the peanut gallery has to say about it - I had thought that if you rotated a monitor that you may need to turn the yoke 90 degrees to compensate if you had purity issues.

I didn't have purity issues after I rotated a betson multisync but something that bothered me afterward was that the convergence seemed more off than before it had been rotated.  Would turning the yoke 90 degrees also be applicable to setting the accuracy back to before they had been rotated, or is this something that just happens when rotating a monitor that you don't have any control over?  I certainly can't complain about the image being horrible with the convergence being off a bit more on it's side, but it's not as clear as before I had rotated it.

if you rotate a tube you don't touch the yoke,that should remain at factory setting.you should put your yoke back to its original position,if you still have purity issues then first make sure the tube is degaussed then if you still have a problem you need to get a grid test pattern on your tube and then starting with green adjust the purity rings one by one(warning this is a big,time consuming job not to be taken lightly and remember you have to loosen the lock ring at the base first)

Hmm, I have a rotating monitor and haven't noticed this.  Although I am using a PC monitor...
