Unfortunately, according to the owner's manual:

	Horizontal Deflection:        31 KHz to 40 KHz

So, the A500's sync rate is way out of the ballpark - I don't think that
there is any way except via a flicker fixer type thing.

BTW - it's a very nice monitor (I'm using it on my A3000) but you can't use
	  SuperHires mode effectively - you can't turn off the de-interlacer due
	  to the above problem...

Just a (mostly) satisfied customer...
