Seems like that there are only Geforce 6200 cards around as AGP.
Should be good enough for 2D operation, but 3D performance is
lagging quite behind the state of the art. Unfortunately, I can't tell for
sure if those cards are capable of displaying 2048x2048, but I guess
chances are good :-)

In the early days of Linux, it was always necessary to supply hand-crafted modelines
to the X-Server - the timing database and tools like gtf came much later!
I was actually wondering that you need a special option (ExactModeTimingsDVI)
for the nvidia driver to make the card accepting self-defined modelines.
However, last time I applied a self-build modeline to a non-nvidia card was
ten years ago, but per Xorg docs, it should still be possible to do so, nowerdays.

I guess you are referring to some kind of intro-screen of the LCD?

Since you have a pretty unusual setup, I fear you need to do some
experimentation to figure that out

Just thought I'd flag this: the specification for video is that the driver and receiver present a 75 ohm characteristic impedance. In an input, that can be manipulated with a 'terminator' - a set of 75 ohm resistors essentially.

You should never put a transformer onto video signals, the only minor exception being special 'humbuckers' designed to filter AC frequencies only.

H & V sync have more variations, but are generally less fussy, as long as there's enough signal for the clocks to trigger, and the reflections are small enough to not mistrigger. They aren't always 75 ohm.

If your impedances aren't matched up, you'll see 'ringing' i.e. reflections down the video line. Nothing in video should ever be 50 ohm. At the frequencies you're talking about, everything in the signal line will need to be very short, and specified for this sort of bandwidth. For instance - a 50 ohm cable would probably look really, really bad. Any sort of video distribution would look really bad unless it's specifically for that sort of bandwidth.

Does anyone know who the actual display manufacturer is of the Barco display discussed in this thread. I know Barco is the company that provides the end product, but do they actually produce the panel itself?

Thanks,

James

Does anyone know wich GTX 260 model get optimal a 2048x2048 60Hz resolution?
I need a good GFX Card to drive a Barco MDP-471 2048x2048 LCD Panel with Analog Input Board. My actually Motherboard have only a AGP Connector. What you think about this Motherboard? DFI LANParty JR GF9400-T2RS, GeForce 9400, S775, mATX, SLI Motherboard. I have here about CUDA???

I'd recommend sending a pm to wyvern666
http://www.nvnews.net/vbulletin/member.php?u=86510
and ask him about details of his nvidia/barco combo.

Officially, the GTX260 can do a maximum resolution of 2560x1600.
However, I know for sure that you can have i.e up to 5040 pixel in width:

Hi James,

I have open my Barco MDP471/CH and the Manufactor from the 4.2MP Panel is SAMSUNG Electronics LTM280T1-L01 and the LCD driver Board is SAMSUNG ISIS2000C8LV4.5 the rest is from Barco i think. @ Time i have use the Quantum Data Video Test Generator 802 for testing my repaired Monitor. It will works... i'm happy Now im looking for gfx card.
I have make a snapshot with the exactly timing and blanking for a 2048x2048 60Hz resolution. This Resolution call BAR2060Q.

Hi!

Thanks for sharing the timing values. The appropriate modeline would probably look like this:

Code:
Modeline "2048x2048@60" 357.23 2048 2090 2410 2816 2048 2051 2054 2114 -HSync -VSync
However, please note that this requires a frequency higher than what a DVI
output is capable (330MHz). On the other hand, my understanding is that
the analog signals on a DVI-D output can go up to 400 MHz? There might
by a chance that there is some nvidia driver specific xorg-option to "break"
the 330MHz limit (maybe "ConnectedMonitor" "CRT" to force assuming a
VGA device).

regards

Bernhard

Hi Bernhard,

This forum is great!!! Thank you for fast answers.
What you think? It's possible to create a 2k resolution with this DFI LANParty JR GF9400-T2RS, GeForce 9400, S775, mATX, SLI Motherboard?

I'm pretty sure that it will work, but I certainly can't guarantee!

My understanding is that all recent nvidia cards can be programmed
up to 32767x32767 - however, at that resolution (and 330MHz pixel clock),
you would get a refresh rate of only 0.3 Hz :-)

BTW.: you could try out if the timings of the modeline in postings #5 and #9
will work (using your test video signal generator):

Pixel Rate: 257.000 MHz

Horizontal:
Active: 2048
Blank: 126
Period: 2174
Pulse delay: 32
Pulse width: 32

Vertical:
Active: 2048
Blank: 32
Period: 2080
Pulse delay: 3
Pulse width: 4

regards

Bernhard

Hi Bernhard,

So, i have upgrade my Computer with the DFI Lanparty Motherboard with Geforce 9400...
and i have Install Ubuntu 9.10 with the proprietär driver... But now?
I'm a half Linux rouky :-) maybe you can tell me the steps to solved my resolution?
When i look my Xorg.conf the file is very small... only edit with post #9 ?
On the side of Windows 7 with the last driver it's a little bit easyler, no command line.
What i make wrong? I have test a lot of values?
I have make a sceenshot...

Right, in ideal case, Xorg will auto-detect/configure the rest.

This is a little bit unclear to my: is the custom resolution as given in the screenshot
not working with windows 7? Or is it working on Windows and you just don't know
how to apply the timings on Linux?

Just recognized, try this:

Vordere Schwarzschulter (Pixels): Horizontal: 42, Vertikal: 3

The values you currently applied are the blanking timings
(difference between total (Gesamtzahl) and active (Aktive)
pixel).


Alternatively, you may try those values as they are working for
wyvern666:

Horizontal:
Aktive Pixel: 2048
Vorder Schwarzschulter (Pixel): 32
Sychronisationsbreite (Pixel): 32
Gesamtzahl der Pixel: 2174

Vertical:
Aktive Pixel: 2048
Vorder Schwarzschulter (Pixel): 3
Sychronisationsbreite (Pixel): 4
Gesamtzahl der Pixel: 2080
