Dual DVI @ 2560 x 1080

[IIO]

if it is not really better or easier than using a geforce 6 i would rather buy a G5 for 120 euro, then i get a spare tower in addition.

But we want to run OS 9 here at insane screen resolutions.......

[IIO]

not sure what you mean. the 9600 pro first shipped with G5s and there is no ATI support for it in OS9.

so why spend 120 for a card when you can get the same card by buying a G5 for less?

[refinery]

The aftermarket 9600 is not the same as the one that shipped in the G5s, it's slightly faster... There's articles on BareFeats about it.

But yeah, not having any native driver support in OS9 kinda defeats the purpose.

G5 cards are AGP PRO, not 4x AGP, so unless you plan on taking a hacksaw to the G5 card it won't fit in the G4's AGP 4x slot.

Some people have been able to do such things with cards that don't really need the extra power supplied by the pins you have to cut off the connector.

Tho the R9600 XT came with a standard non "Pro" connector with 128MB VRAM and can be used in some G4's when taping pins 3 and 11, it doesn't support Dual-Link DVI. The R9600 Mac/PC Edition has 3 external TMDS's and can drive one Dual-Link DVI display as well as a standard DVI Single-Link display and has a 256MB VRAM.

There is a Native Device Driver( 'NDRV' ) for OS 9 support, you just don't get any 2D/3D GPU acceleration, but you can drive displays at insane resolutions, and that's the whole point of this thread, more desktop spaces when using static windows.

There was a R9650 that had dual dvi and can drive one single link DVI and one Dual-Link DVI with 265MB VRAM, but good luck finding one for less than $120, tho they do pop up from time to time at good prices.

Drats! Foiled again by an $8000 display and a $20 PowerBook!

Whou...monitor that support 13 hz!

so i just found out that you can actually buy dual-link DVI-D to 2x DVI-D Y-adapters - and i wonder under what circumstances they can be used.

proof please


However, there are some displays that can use a split connection, such as the IBM T221, or the Dell UP3214Q, there are probably others that split the screen into two parts and you display them together
Possibly new strange LG displays

that´s what i also think, that it will work only for special monitor models.but it is nowhere advertised like that.

the normal way would be to use an active splitter (1). they have an EDID learning function to find out which port has the monitor and what it needs and you can send stuff with jumpers. even these only duplicate the image.

but i have no idea how Y-cables (2) should work. Y-Cables also just make a copy, for example to record the GPU output with a recorder.

there are even DVI to dual VGA splitter cables (3), which makes even less sense.

probably all of it is simply false advertising. you can also find "DVI-D to DVI-I cables" on alibaba, hahaha...

[DieHard]

Cool in theory, but no there are not... yes that makes no sense and AFAIK does not exist

If you look at your last pick, the cable it is NOT DVI to (2) VGA, it is a "breakout" DMS-59 Male used in many low profile older nVidia cards, it displays Mirror or extended desktop as normal on (2) VGA displays, note that the card connector is NOT DVI, it is a proprietary connector (DMS-59 Female)

Cable only:

yeah but it is not only the wrong advertising, i already question the idea to make a duplicator cable which has a dual link connector on the one side and 2 single link connectors on the other side.

this is probably what makes the shop owners think it would split the signal into 2 smaller ones, but it does not make any sense to build a cable like that, a single linke DVI connector would be enough.

this is the same nonsese as the famous usb to firewire adapter if you ask me.

 here is a solution that in theory can start a 2560x1600 display
