Is it possible to use a high-res screenmode on a pal tv without flickering and without flickerfixer?

[leirbag28]

oops!  I forgot to mention...on top of Everything I just said.....if you want even less flickering....add a genlock (I guess a PAL one for you) like the SuperGen SX and click the notch filter.....it adds some anti aliasing so it now might look a little blurry....so I definitely recommend using bigger and thicker fonts like FuturaB 12 or Workbench 12...................I use my Amiga on an NTSC S-Video TV  full time! and its excellent!

... greatly against the one pixel thick white lines........ Solution? get ...

a high resolution monitor and GFX card :-P
Sorry, I can't help it when people still want to use such old crappy technology. I'll try to behave in the future, honetly I will. :crazy:

Ok then. That program helped a little. It would´ve been nice to see the ham version of it. However, Ill get a flickerfixer...

[Ilwrath]

You remeber that program too? You must be old like me

Yeah, I'm old enough to remember it, too...  Of course, I also remembered it didn't do me any more good than a nice low-contrast palatte did, plus it made stuff harder to read, IMHO.  ;-)

I stand by my advice, though, perhaps the sunglasses are also helpful.  :-D

There was a patch years ago that ran PAL resolution in NTSC refresh. It was pretty stable, combined with editting the gadget widths/colours as above, and I got a pretty stable WB- without having to resort to 16colour. Your TV had to support both PAL and NTSC though.

The original question concerned pal tv sets and as Karlos said, the 100Hz will do this because they use double-buffering like a Flicker-Fixer does!

I recall that Lowe and other German sets had models with this feature.

Standard tv sets use a 50Hz refresh rate that allows only HALF the scan-lines to be written each go. Interlacing allows the between scan-lines to be written.

clariSSA was an Amiga animation application that allowed animation-frames to vary at EACH half-frame, and thus produced SMOOTH movement at 640x512/640x400 formats.

Ah, a flicker-free 640x512 screen on my 1084S, that
has been my dream for many years. Using the
euro36 driver the flicker was much more acceptable( it won't work on a normal TV set, btw).
I kept using an interlaced screen until a summer, when I had some type of light epilepsy attack, or this is what I think it was. At that time, after one week I haven't touched my Amiga, I saw some sort of flashes appear in front of me, even if it was daytime and the people around me didn't noticed any flash. I was quite surprised. After this  I decided to borrow a VGA adaptor and to buy an expensive 17" vga monitor. A wise choice, as I never ever had this type of problems again.

The irony of all this is that interlacing was originally invented to *reduce* flicker!

I used to use interlaced mode but only using low brightness and very low contrast.

If you want to sit in front of a computer for a long time get a monitor which can handle 85Hz.
Alternately get an LCD screen which doesn't flicker at all (at least not noticably) ...but they do effect your eyes.

Also don't use fluorescent lights as they can interact with the screen (TV and monitors) and cause yet more flicker...

Hi-res interlace will always flicker on a TV.  However, there are tricks that you could reduce it.

1. use related colors and no thin horizontal black & white lines
2. turn down your contrast on your TV
3. if you are familiar with art programs and you use graphics that flicker in your background, you can reduce the sharpness.  Reducing sharpness allows other colors to blend in a little and help reduce the flicker like a slightly out-of-focus camera.

To eliminate the flicker, simply select a screenmode that does not have the interlace feature.

Yup, no flicker on an LCD-tv either, I have tried with an handheld Casio.
MagicTV worked fine on CRTs good enough for DOpus but not for reading or editing text.

Interesting, how did the tv identify it as PAL or NTSC?
What was the name of it?

That's because LCDs don't have a refresh signal like CRT. Trouble is, one is likely to cost as much as a SVGA monitor and graphics card together.

I know.
Couldn´t read much at a 4 inch screen anyway.
