1084s monitor is flickering with Classic W.bench

[petercli]

Hi,
 
 I installed Classic Workbench on my NTSC  A1200 following these instructions (https://www.youtube.com/watch?v=Zd42RsKHm5Y&noredirect=1)
 
 I have a 1084s monitor.
 
 I am seeing a lot of flicker . Before, with regular Amiga W.bench 3.1 I don't recalling having so much flicker.  Any idea how to fix this ?
 Should I   move to a LCD monitor ?
 
 Thanks, Peter

I switched from 'PAL HI Res Laced' to 'NTSC HI res' , and it looks a lot better.  
 
 The Indivision 1200 AGA MK2cr (which replaces the Indivision AGA MkII) looks interesting.
 
 Thanks for the tips.
 Peter
