>256 colors with Indivision for A1200?

[Piru]

You installs Indivision Screen Modes in Devs:Monitors?

No.

Lets try again:

1. Indivision AGA isn't a graphics card
2. Indivision AGA doesn't give you any more colours
3. Indivision AGA does not give you 15, 16 or 24-bit modes

[Kronos]

Simplified:

AGA has 3 different (fixed) pixel-clocks:
LowRES,HighRES and SuperHighRES, each doubling to the one before.

SuperHighRES in 8Bit needs such a bandwidth that it uses up allmost all clock-cycles that would normally allow the CPU to access the ChipRAM. Thats why it feels so slow.
HighRES in 8Bit only uses the clock-cycles that are assigned to the chipset anyways.

All (AGA) screenmodes are based one of these, increase the pixel-count and you have to reduce the refreshrate and vice-versa.

One could in theory create a 1280x1024 screenmode based on LowRES, problem is that it would refresh only at about 3Hz. Same mode in HighRES 6Hz, SuperHighRES 12Hz ...

Actually one can get slightly better refrsh-rates by useing overscan.

[Thomas]

I've always found that an interlaced screen at the same res and colors is faster than a native dblscan or productivity.  I'm assuming then using the de-interlacing function of the indivision will in practice therefore give you faster display at the same res and color depth and refresh rate

Certainly interlace is faster than dbl because dbl has to transfer twice as much data in the same time as interlace. Therefore the CPU has only half of the cycles to access chip-ram.

@Thomas

Indivision is the only scandoubler which supports the HighGfx monitor driver which allows to use resolutions of 1024x768. So effectively the Indivision *does* allow to use higher resolutions.

It's not the only one. Compserv Flicker Fixer II was the first flicker fixer in supporting HighGfx:

BTW, there are 24bit scandoublers like Compserv Arxxon. Others are not 24bit (like cv3d scandoubler). PicassoIV is 24bit but doesn't support super-hires so some demos don't look perfect.
IMHO best Flickerfixers are Indivision 1200/4000/ECS.

[stefcep2]

so where can I get the Indivision 1200 from?  Amigakit's site takes you to indivision 4000/ECS only.

[AmigaHeretic]

It won't work. Indivision AGA isn't a graphics card.

I still think the marketing should be more clear about this. I am not so sure if you're the only one fooled by that "24 bit" clause.

I don't really think it is misleading.  It's "24bit" a lot of scan doublers are not 24bit.  It's actually really hard to find true 24bit ones.  A lot do that 6bit 7 bit 6 bit crap and AGA ends of looking horrible.

I think they're out of the A1200 version at them moment, and they plan to get more.

Talking for myself ...

Hardware:
I am doing some reseach and testing for a automatic monitorswitch.
http://www.a1k.org/forum/showthread.php?t=19511
Jens got a sample and i promised him my free support if he could do something "commercial" as an addon for the Indivision-series.
At the moment I do some research in direction of the WT8048-IC ...

Software:
As you know, before HighGFX the Super72-mode was the highest screensolution with 1:1 pixelratio.
These modes can be used with the ECS-chipset, but they are limited to 4 colors out of 64.
If you like to use 16colors (MagicWB or WB3.9) you are limited to 640x512.
Compared to the breaktrough of HighGFX on AGA, I am gone release SuperPlus in the future.
Presenting a ECS-screenmode with 800x600 in 16 colors out of 4096.
A IndivisionECS will help you to keep your eyes intact, but it can be displayed on some tolerant displays without Indivison (tested on a Iliyama 5017).
SuperPlus is also interesting for the AGA-chipset, because it used the "HiRes"-mode with 70ns instead "SuperHiRes" with 35ns pixelclock.
The display-DMA is not that heavyloaded like in Super72 and displayoperations are faster.
The Indivision-series (ECS&AGA) will need a firmware-update for this mode, it depends on Oliver and Jens to support that mode.
(Just like Xtreme-support...)

DualScreen-Mode is a littlebit difficult and I do my best to release a stable and usefull driver for it.
I´d like to combine it with the SuperPlus driver to enable a 1600x600 dualscreen in 16 colors with "usefull" speed.

What would be the speed with 060/50Mhz and Workbench in 256 colors via Indivision Aga? I was trying to find some movies on YT but there is non with that config..

Yep there is 256 color AGA only Workbench

[kolla]

I wish there was some screenmode that could let my Indivision AGA do 800x600 properly.

[warpdesign]

Thus their claim to support 24-bit colour is fine but they should be clearer about what they mean by that.

It is misleading: two or three people here already got wrong because of that. Unless you're really into technical stuff, you'll interpret it as supporting (adding) 24bit in AGA. Weather it was done on purpose or not is left to the appreciation of everyone (I wouldn't be surprised it was).

Adding something like "full-AGA support, including HAM8 modes (HighGFX HAM8 supported)" would be ok as I see it.

This is getting silly. First of all, the description is perfectly accurate, and there's hardly any other way to put it. Secondly, why on earth would Jens&Co want to create so much trouble for themselves by doing false marketing, as you suggest? It's a scandoubler/flickerfixer - if some people dont know what that is, that is _their_ problem. Maybe they also think that if you watch "plan9 from outter space" on a new 50+ inch LED TV, it will suddenly be in colours? After all, it is a colour TV, right?

Adding something like "full-AGA support, including HAM8 modes (HighGFX HAM8 supported)" would be ok as I see it.

That would not be an accurate enough description, would it?

Nowhere does it claim to be a graphics card.
Nowhere does it claim to add 24bit screenmodes.
Nowhere does it claim to make the graphics faster.
Nowhere does it claim to make the machine faster.
Nowhere does it claim to make your penis bigger.

It's just a scandoubler/flickerfixer with 24bit output.

Sure, where else ?

Quite a long outtime you have taken ..... *g*

So I when it's released we should get a nice fast 800x600 256 colour mode

Yay! Looking for forward to it!
