Okay..tried another one....just hooked up the MDD via the DVI-D/VGA adapter to my 27" Dell U2713HM...though analog signals...but also not bad @ 2048x1152 resolution (o;

[IIO]

great! but one must be very careful that he dual DVI-D adapter has a true 42+1 connector, right?

[IIO]

no wait, isnt that a single DVI-D? 2048x1152 is close at the border of one dvi signal.

edit: 4,1% more than 1920*1200.

[davorin]

Yes..it's just the RGB analog signals coming out of the DVI-D connector (o;

Hmm..maybe switch some FPGA code between the two connectors (DVI and ADC) and generate a higher output resolution ;-)

I assume there was never Dual DVI support under OS 9, right?

[IIO]

nope, never.

it would be awesome to get 30" working, but we dont even have the videocards for this resolution in OS9. the Radeon 9200 for example only supports 2048x1536.

It works with 30" Monitor in 2540 x 1600 resolution and for instance a flashed GeForce 6600 in a G4 Mac
Unfortunately without QuickDraw acceleration

A Radeon 9600 should work also (without QuickDraw acceleration)

See here (unfotunately a german forum - but I guess you can get an impression from the screenshot):

I myself use a 27" iMac with sheep shaver and OS 9.1 in 2540 x 1440.


that's a gorgeous big desktop - isn't it?

[IIO]

i believe that no quickdraw, no 3d and no official driver support are three conditions too much.

i woudl already hesitate putting a PIC express card in my G4s, not talking about modifying drivers and firmware.

but it is great to hear that someone has tested it.

Hey guys!!

Hope you all are doing just great. I've got a related question to this. I've done dual monitors on a G4 mirror door many times also gotten 2560x whatever (can't remember now and not in front of it) from an Apple 30" display (looks killer and these seem to be a bit had to find now) over dual DVI.

I'm interested in doing something totally different now for my main rig.

I'd like to run OS9 on my main rig (sharing mouse and keyboard but somehow without a crappy KVM, I've had bad experiences with these). My main display is an Acer ET430K (they're incredible it's 40" and runs 3840 x 2160).

Somehow (maybe 2x dual DVI graphics cards in my expansion chassis or something else equally crazy) run basically a two monitor display on my main monitor. Thats a lot of conversion and a lot of graphics cards to make it happen if possible. So basically my main display would be split into a side by side 1920x1080 configuration or something else clever.

Also makes me think on all you guys fancy 9.3 stuff my number one wish was higher monitor resolution!
All my best,

some older 31,5" or 40" from ~2010 will work fine, but in my opinion it doesnt make much sense to go above the DVI limit.

i only use 1920*1200 because of exactly that - so you can make use of the DVI connector if one of your cards has that as second port.

there is nothing more unelegant than monitors of different size and resolution. even on different machines if it is the same work space.

[SonikArchitects]

Hey IIO! I couldn't agree more yet in this space there is no way to swap monitors at main mix position. If anyone else has any ideas again what I am looking to do is display 2x pages on one 40" (modern monitor) side by side (but on the same display).

I'm gonna crack it. Help appreciated!
Best,
_BT

there are VGA signal splitters which let you distribute one signal to more monitors (matrox triplehead and the like), but i wouldnt know about something which lets you concatenate two signals. (think about it: the signals would have to be in snyc)

the only thing i could imagine is that you tear apart the matrixes from 2 monitors and include them in a custom frame/case.

i once wanted to do that with my samsungs, but since i have 3 there is not much sense in arranging them other than slightly convex. (plus i cant really complain about their frame, which is like 13 millimeters at both sides - and you will never get it seamless anyway even when you remove the plastic.)

My main display is an Acer ET430K (they're incredible it's 40" and runs 3840 x 2160).

just to point you into some direction:

found it by image search for 'video mixer dual (quad) DVI'
(you probably don't want broadcast gear)
essentially you have to feed the mac output into some box like this

[IIO]

PIP/PAP sounds like something i also want to have.

p.s.:

these NTI guys are awesome. did you notice the search query tags and the online demo of the admin software?

but 1500 euro...

[Philgood]

They even have support for Mac OS9!

[IIO]

i believe that four "monitors" from your G4 GPU arranged as square is the only option how it could work. or 2x2 from 2 computers...

ultrawide e.g. 3800*1600 as a solution for "2" is still too high.

VGA to HDMI is doable - adapters are starting at 10 euro and are not too big.

[IIO]

damn, i think we´re wrong - the output is also only in ~2k?

[Philgood]

But they have 4k versions although more expensive.

[k-Tracker]

Just to document here. I got GF 7800 GS OC flashed and running with Apple Cinema Display 30" under OS9. Looks very nice.

[IIO]

great, finally someone did it. could you elaborate on the 2d acceleration and add the required software?

[Bolkonskij]

It might sound silly ... but why on earth do you want to run OS9 on such high resolutions? You have any applications that can be used more productively when run on a huge resolution? Or is it simply the interest in what OS9 is capable of? (<--- seriously interested in the answer)

To answer the question above - I usually run OS9 at 1280x1024 (still high-res to me ) and I wouldn't know why I should go any higher. Whenever I should indeed run out of desktop space... well, there's windowshade
