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

Watched the video and he seems to be working with what he calls, an "Ami-ger.". Second his Ami-ger has an AGA MKII flicker fixer, so it will appear his Ami-ger has no flicker in the interlaced modes with 400 - 512 vertical resolution.  If you have flicker on your 1080 monitor, you can not de-flicker either an Amiga nor one of those Ami-gers with a 15.7 kHz monitors.  You need a monitor that accepts 31 kHz input.  Then with an AGA MKII flicker fixer, you can have a high resolution screen without flicker.  Actually there are other devices to achieve this, but in summary an A1080/1084 shows a standard screen with no higher resolution than an old TV (200 TO 256 lines of resolution); when the resolution is doubled, the lines alternate in being displayed and flicker.  This would happen on a LED/LCD/plasma flat-screen if the input is 15.7 kHz.  So you need a monitor that accepts at least 31 kHz input and a way of getting said output from an A1200 (which normally only outputs 15.7 kHz.  It also helps to pronounce "Amiga" the way is is spelled, even if you are dyslexic -- it is like the dyslexic Satan worshiper who sold his soul to Santa.
