We are assuming too much. Its a A34 price, plus resellers need a margin ontop of that, or its not worth the effort/hassle.

Retailers buy at a lower price. Don't think Amedia will pay more than 450 for a single v4. They sure have to make some money on the products but not to the point that can hurt the sales..
I think that Apollo Team have to set a suggested retail price and maybe sell by itself his products to avoid any speculation.

Anybody else notice (at least from the writeup and the renderings from Amedia) that it looks like the Vampire team removed the 40 pin IDE header and left only the 44pin?
 
  I guess I don't have a problem with that - I have been concerned all along how they expected users to power devices with 40 pin interfaces since they usually expect the 4 pin molex connector that includes 5V and 12V inputs (but this board only has 5V available).
 
  Tried to get confirmation from Gunnar in IRC earlier today but I guess I missed him...

Edit: Confirmed from Gunnar... 44 pin header only. And it was exactly for the reason I stated above..

OMG Awesome!

Will the board be available on it's own as well? I have plans on 3D printing a case for it and seems wasteful to have the aluminium case as well!

Yes, board and dealer made Sys Are ready for preorder at Vesalia and amedia

Sad... Inexpensive Disk On Module and CF Adapter use the 40-pin IDE connector and don't require +12V.

Just get a 44->40 pin adapter.  Amazon has them.

Cost less to put it on the mainboard at users can chose.

Has there been improvements on the DIGITAL-VIDEO output?
What is the maximum reliable resolution at 50/60 Hz?

Judging from the images, the wiring for the 40 pin IDE is still on the board, so I guess you can solder the connector yourself?

Why do you ask for 60Hz?
Herz has not the same meaning anymore today with LCD Monitors.
In the "old" days more Herz means nice picture with less flicker.
This is not the case anymore today.
Today a Monitor will not flicker anymore and a picture will look as nice with 10 Hz as with 200Hz

But then any motion on the screen will look shitty.

So what is the officially supported resolution and refresh rate for the V4SA?

Aha so you talk about motion.
 
What do you want to know now?
The supported still resolution or the resolution the system can e.g. fluently move in motion?
 
The problem with your question is - its not clear what you want to know - and if you understand the technical conditions.

Talking about MAX resolution on AMIGA and at the same time about Motion contradicts each other completely.

Lets make an example to clarify this:

AMIGA 1200 AGA
It could display 640x480 in 256 Color at 60 Hz.
This means the screen was flickerfree.
Still it could not render this in realtime.
So while a still picture looked good.
Motion like moving a window did never work on this smoothly!
So motion always looked "shitty" like you say in the resolution.

So if your question is about motion - then it becomes very complex to answer.

No, my initial question was very simple.

What are the supported resolutions at which refresh rate for the V4SA product?

  There is no simple answer to this.
 
 
 
  As you know the V4 resolution is freely programmable.
  This means using the AMIGA Monitor tools you can define an
  nearly infinite amount of resolutions and screen modes.
 
  You know AMIGA OS, you can define as many resolution as you want.
  This is not a MAC where can only select between 3 sizes.

I think something is getting lost in translation...

Gunnar - he's not asking how fast can the content be drawn for the desktop (which is a function of the speed of the chipset/RTG implementation at that resolution). He's asking what's the refresh rate of the DIGITAL-VIDEO signal being pushed out when at that resolution.

If the content is produced quickly, but the refresh rate of the signal is low you get tearing/jumping effects on the screen.

Likewise, if the refresh rate of the signal is quick, but the rendered content is slow you'll get similar effect.

Most likely :)

You are correct.
 
The facts are simple:
 
You have no flicker ever on LCD.
So HERZ is totally irrelevant to this.
Your LCD will never flicker not with 10 Hz and not with 400Hz.
So if you worry about flicker, then asking for Herz makes no sense.
 
 
If you worry about "smooth windows" movements.
Then its crystal clear that you only get smooth movement
if BOTH the rendering and the refresh rate are high FPS.
 
Again talking about HERZ is totally irrelevant now.
As the rendering speed is always the main limiting factor NOT the Herz.
 

Sorry to be picky here, but I want to give the best possible answer.
And I do not want to mislead people

To me the question sounded a bit like
"What max speed is printed on the speedometer of this car?"
I would then assume he in fact want to know the max speed of the car. And not the unrelated printing on the speedo.

Do you agree that 1280x720@10Hz are useless for most of the users? Except you want to use the V4SA to display some pictures only.

If it's freely programmable, then 1920x1080@60Hz is something you can confirm, right?

Another try to rephrase the question :)
   
    Gunnar is the H D M I out fully compliant with H D M I standards (which version?), i.e. will it support these official H D M I resolutions:
    1440x480@60
    800x600@60
    1024x768@60
    1280x1024@60
    1400x1050@60
    1600x1200@60
    1280x800@60
    1440x900@60
    1680x1050@60
    1920x1200@60RB
    1600x900
    480p
    576p
    720p@50
    720p@60
    1080i@50
    1080i@60
    1080p@50
    1080p@60
 
  Update, I guess the forum replacing my text H D M I input DIGITAL-VIDEO already partly says it's not officially H D M I compliant (i.e. no H D M I license).

to my knowledge, the vampire has never claimed to be H-D-M-I compliant with any of the H-D-M-I versions.
 
  the vampire is fully programmable to push video out of the digital video port that falls within the understood specifications for digital video transmission - within the constraints of the hardware.
 
  as far as i can figure, the memory bandwidth (clockspeed*64/8) is your main factor. So a vamp with an 11x clock multiplier of 7.09Mhz yields a memory bandwidth of 595.02 megabytes per second.
 
  for example:-
  the video resolution of 1920x1080x32bpp@24hz requires 190 megabytes per second fed to the graphics chip - irrespective of what the system is doing, so whats left of 595 minus 190, is available for system use.
 
  so you can do what ever resolution you like, so long as it's within the available memory bandwidth of the vampire, and that the display it's connected to the other end, can cope.
 
  it is not h-d-m-i 1.4 or 2.0, or whatever.
 
  i hope that is somewhat accurate, and vaguely helpful.
