Hm, could you point me to a reliable analog to digital converter?

All the ones I have seen are limited to 1920x1200. Most of them are limited to 1600x1200. The specs I have seen are not very informative; most likely you'd have to buy one and mess with it to find out its real capabilities. But I doubt you would be able to get 1900 x 2400 in anything off the shelf

It also appears they are all made in China for fifteen bucks, then sold under various flybynight brand names in the US for about a hundred. So the hot ticket would be to find one in its native environment. This might be an answer for Octaners who want dvi, too, come to think of it ... Up until now the only choice has been to buy a dcd. Kind of a waste of a perfectly good dcd ...

Does this means that the Onyx2 deskside is clearly ruled out from the 3840x2400 game?

Clearly ruled out?

If you like the idea of having a T221 on your Desk and an Onyx2 next to it (and I'd agree that they'd make an impressive combination), then before throwing in the towel it might be worth taking a little more time to investigate and/or test a few of the analog-to-digital converters to find out if 1920x1200 was given as the max resolution because the device is limited to single-link/165MHz DVI resolutions.

1920x1200/WUXGA (rather than the pixel clock rate) is commonly cited as the upper limit for single-link DVI. 1920x1200 is the highest given by SGI in list of resolutions published for the the VPro/V12, but because the pixel clock is under the 165MHz limit, hamei's V12 is still able to run 1920x2400@33Hz because the low refresh rate puts it within the single-link pixel clock spec.

If you still want to try, it might be easier to start a test of an analog-to-digital converters at 1920x1200. That'd let you evaluate image quality while using the converter within the stated max resolution. One channel at 1920x1200_60 (using the SGI-provided vfo) will fit in the DG's bandwidth, or you could test the converter against a lower refresh rate using one of the T221 modelines:

Code:

  Mode "1920x1200_41": 104.8 MHz, 49.6 kHz, 40.9 Hz
  
  Modeline "1920x1200_41"  104.78  1920 1928 1960 2112  1200 1201 1203 1212

On the odd chance you might find it helpful there's an IR-specific 1920x1200_41 attached.

No guarantees but there is a possibility that the Matrox TripleHead2Go deadlybobber might be able to take the single IR analog output and split it into two dvi monitor inputs.

I have no idea how versatile it is on refresh rates and so on but It sounds almost exactly right ...

Recondas,

Could you please also provide me with a "IR_1920x1200_48-T221.vfo", I have the DG5 version of this display, which allows 48Hz natively.

Thanks.

I actually pulled the 41Hz version out of the "/var/X11/Xvc/SG2_0_TimingTable" section of the xfree log file from your Onyx4 (and unfortunately it's the only single-tile 1920x1200 modeline in the log file).

I'd be glad to build an IR-formatted 1920x1200@48Hz if we can get the correct single-tile T221 timing. Could you connect the T221 to a PC and capture your T221's EDID?

Oh I see, of course, as soon as I receive the cables, in a few days from now.

Actually, there isn't "an" EDID. There are five or six of them. You can choose which one it transmits from an on-screen display. Somewhere in one of the manuals it tells how to choose which edid you want to give to the computer.

The monitor is smarter than most computers

mia - it doesn't care much about the incoming frequency. You can feed it 1920x1200 at up to 75 hz, I think. 60 for sure. So you don't really need a special vof just to try. IR will do a single 1920x1200 @ 60 stock, won't it ?

I see your point, you're right.

Gotta poke around some to find it, but there actually is one at 1920x1200:

Compositor is stricly digital inputs ? The Matrox Dualhead2Go and TripleHead2Go thingies look like a godsend for IR these days.

About edid, expressed myself badly. The numbers would be interesting and helpful but usually edid is intended to give you the exact timing used by the panel because the graphics card drives the panel. But in the case of the T221 it doesn't matter, because you never get the timing used by the panel itself. There is a frame buffer and circuitry in-between. So anything you can feed it that is reasonably close will be fine. They created multiple edid's to overcome graphics card limitations, not the other way 'round.

One of the manuals explains it something like "If you are using this card and want this refresh, set the edid to this number and we'll do the rest."

Basically, anything you can feed it will be fine because it's going to take that, put it into its own frame buffer then redisplay it at the exact correct size and frequency it wants. It might be interesting to try some setups with zero front porch and zero back porch to save transmission bandwidth and see what happens. It may not even really care what frequency you use, since it will refresh the panel how it sees fit.

Cool system

I'm pretty pleased with it, and all told I think I only invested about $500 in it total (machine, CPU upgrade, RAM, cards, hard disk). I spent nearly as much on my Indy, though the Indy is very special to me for nostalgic reasons.

I'm toying with getting a Tezro, but it would be very costly and I don't think it would be anywhere near as fast as my quad G5 of similar vintage (which is also currently completely sufficient for all my tasks but TurboTax and Android work) based on my experience with the single core in this. What's people's thoughts?
