FYI 30kHz is not the refresh rate - it's the sync rate.

The refresh rate in PAL modes is (IIRC) 50Hz, 60Hz for NTSC. If 50Hz is too painful, switch to NTSC (though it's a slightly lower res).

For an A1200 you would require Zorro & Video Slots (ZorroIV for example). Ive heard that people used Towered A1200s with PicassoIV but I don't know anyone in person. It will depend a lot on the VideoSlot implementation, it's the first time I've heard that Picasso4 flicker fixer has problems with A1200 Zorro video slots...

I'm afraid you won't be able to find much better flickerfixer's than AmiKit ones (at least for A1200). It depends on taste... I was used to an Arxxon Scandoubler and they first time I saw a CV3D Scandoubler it felt horrible because it was not a true 24bit one... I hope AmigaKit ones are true 24bit ones and are not as crappy as phase5/DCE ones.

I agree with you, 50Hz or 60Hz harms my eyes too. We are lucky nowadays most of stuff is RTG... but a FlickerFixer is a must if you want to see games/demos or simply the early boot menu.

If you don't like AmigaKit scandoublers you can always buy an A4000+Picasso4 ;-P

Crumb, of course if someone still use aga, 50 or 60hz is good for they, but for me (i have Micronic Scandy 1200) - it is really suck :) If look at white screen over this device, it just killing think :)

Also, on my voodoo3 i have 110hz for 1024x768 resolution, and of course, after it, 'just doubled' aga singnal it is pain. I agree, that >60hz is good for eyes, but lower is pain.


So. amikit, PLZ , give to ppls FULL TECH. INFO about this device :) thanks.

You could also use the TV Card to capture AGA output, so you would see it a little blurry, but at 110Hz

It doesn't work with all demos/games and of course you won't be able to see the early boot menu...

200hz! Sweet!

ps: theese days i have a 23inch eizo monitor with 200hz 1024x768 .. not good for my eyes either really but its sharp as hell ;)

1024x768 on a 23"? What? You could start counting pixels with that resolution! Why don't you select a better mode? More desktop space...

That's what Vesalia says (EUR 132.90):
"Indivision - External Flickerfixer for Amiga

Indivision is an external Flickerfixer (aka De-Interlacer) for Amiga computers. Just connect it to the RGB port of your Amiga and put the monitor plug into Indivision, and you're ready to go, no additional hardware or software installation is required.
Indivision doubles the line (horizontal) frequency of all 15 kHz modes, enabling the use of PAL modes with VGA monitors or TFT displays (scandoubler functionality). Furthermore, since Indivision is not only a scandoubler but a flickerfixer, the flickers of interlaced modes such as PAL Interlaced or NTSC Interlaced are removed (also often referred to as "De-Interlacing".
Screen modes with higher horizontal frequencies such as DblPAL or Multiscan Productivity are passed to the monitor unchanged."

Yes 30khz is absolutely fine with me, you got super-sensitive eyes or something??? My PC displays are always set to vert. 60hz as well - cos I like as big a resolution as my monitors allow and that's usually all they'll manage! And my monitors are usually cheap ones too!

30khz is the horisontal frequency, not really what Kas1e means.
He's talking about the vertical frequency update which has been proven that most
people need atleast 72Hz to get a comfortable screen which have no flickering at
all. Setting the screen mode to about 75-85Hz usually works for everyone.

Some people do actually have more sensitive eyes. I can actually feel flickering
when setting a screen mode to 75Hz but none at 85Hz.

50Hz or 60Hz is horrible to sit in front of, even with a flicker fixer (deinterlacer), if
you're doing stuff like programming, office stuff, reading. Really anything that you'll
have concentrate on details for. Games on lower frequency's are not a problem as
you usually never notice any flickering because of the high speed movement on the
screen.
Although a flicker fixer greatly helps the use of Workbench/utils/programs for those
without graphics cards for the classics. I would strongly recommend any user to
get a graphics card instead for any serious work.

Just try using a PAL 640x512 50Hz (with a flicker fixer) for one hour and than switch
to 640x480 85Hz and you'll notice the difference for sure.

Nuts!

I've just gone and bought a TFT with TV input and 1280x1024 screens capability to sort out my dual display problem for £200!

So, amikit, where you ?:) tell us technical information about vertical frequency ? 30? 50-60hz ? more ?

I actually need 85hz to not be bothered by the flicker on a crt monitor. Anything under 75hz makes my eyes feel like they are burning.

I totally agree with Tomas. Anythink lover 85hz is unusable. Maybe 75 can be good .. but 60,50 and lower it is pain as i said. And 'work' it not except. I was try to play in old game 'Walker' on my mirconic scandy scandoubler, and it is SUXX. after 10 minuts my head start to boring and eyes crash up :) but i do not have any 'senless' eyes and i do not have problems with it too :)

We have tested the Indivision on a Philips 190B4 TFT screen here with the
following specs:

Vertical refresh rate: 56Hz-76Hz
Horizontal Frequency: 30kHz-82kHz

What specific tests do you want me to conduct and I'll post back here?

@amigakit

this is specs of monitor ? i mean need tech. specs of scandoubler. What do it exactly this device? How much of horizontal freq is output by this scandoubler ? For example i run any AGA game, and output in horizontal freq. will be ? ( i mean scandoubler output, not monitor features). In other case, any scandoubler device work with signals and double it, any flikerfixer must fix the 'fliks', but what about output values in end ?

Hey is it me or is this a CRT only problem???

To my recalling a TFT does not know what interlace is..
And because it handles the drawing of pixels differently a higher frequency is not
needed on those monitors. Often TFT's won't allow more than 70-75HZ because
of this.
