Default 2560x1600 display issue. (x11?, nvidia 8800 GTS, hdmi, dvi-d, Dell U3011)

I received the Dell U3011 monitor today, which has a native display
resolution of 2560x1600.

I have an HP HDX9494 with an Nvidia Geforce 8800 GTS video card in it
that I am using to drive it.

The user manual for the U3011 is here
http://support.dell.com/support/edocs/MONITORS/U3011/en/ug/about.htm

The specs for the HDX9494 is here
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01490775&tmp_task=prodinfoCatego ry&lc=en&dlc=en&cc=us&os=2100&product=3747924&sw_l ang=

Info on the Geforce 8800 GTS is here
http://www.nvidia.com/page/geforce_8800.html
http://www.nvidia.com/page/8800_tech_specs.html

The problem is that I can't get the laptop to HDX9494 to drive the U3011
at 2560x1600.

The U3011 has several inputs, HDMI, DisplayPort, DVI (Dual link) and
VGA.

According to the manual, the "highest preset resolution" of the monitor
when using the HDMI input is 1920x1600 @ 60 Hz. The "highest preset
resolution" is 2560x1600 for DVI and DisplayPort inputs.

The HDX laptop does not have a DVI or DisplayPort output. It does have
an HDMI port.

According to the GF8800 documentation, it has two dual link DVI ports
that support 2560x1600.

The HDMI wiki tells me that HDMI 1.3 should support 1560x1600@ 24 bits
at 75Hz. HDMI 1.3 was released in 2006 and the HDX was built in 2008.
http://en.wikipedia.org/wiki/HDMI

When I connect the HDX to the U3011 HDMI port using a High Speed HDMI
cable, the maximum resolution I am able to select from the configuration
software is 1920 x 1200.

When I connect the HDX to the U3011 DVI port using a High Speed HDMI
cable and a dual link HDMI to DVI adapter, the maximum resolution I am
able to select from the configuration software is 1600 x 1200

I have tried this with both the proprietary nvidia driver and the
nouveau driver.

I have tried manually editing the xorg.conf file with various modelines
to no avail.

When I run the nvidia-setting software and look at the properties of the
display, it shows a dual link connection for the built in 1680x1050
display and a single link connection for the HDMI device.

How do I get my HDX to drive the U3011 at 2560x1600 ?

Is this a hardware problem or a software problem ?

Does the nouveau driver use the xorg.conf file the way the proprietary
driver does, ie does it use modelines ?

Thanks !

I use modelines for a monitor that doesn't do EDID (at least not properly)
with an NV28 in order to get it to use 1280 x 1024 instead if 1024 x 768.

Some time ago I had a slightly similar problem,
but I had no idea how to generate the correct
modelines, and because I was afraid I would fry
the monitor , I did not experiment.

For the answer to this question, look at your /var/log/Xorg.0.log file,
and follow the messages of the nouveau driver as it initializes itself
and determines modes and resolutions. Its very informative. If it is
excluding the resolutions you want, you'll at least know *why* it is
doing that.

I played around with this tool.
http://xtiming.sourceforge.net/cgi-bin/xtiming.pl

Not sure if its current or not. When I plug in the numbers from the
U3011 user guide, it spits out settings for 2560x1440 instead of
2560x1600.

Makes me wonder if the nvidia and nouveau drivers have a software
limitation of some sort, thus my question of is this a software or a
hardware issue.

http://www.arachnoid.com/modelines/ give me

# 2560x1600 @ 60.00 Hz (GTF) hsync: 99.36 kHz; pclk: 348.16 MHz
Modeline "2560x1600_60.00" 348.16 2560 2752 3032 3504 1600 1601 1604
1656 -HSync +Vsync

which doesn't agree with the number from the table in the U3011 manual

VESA, 2560 x 1600 98.71 60.0 268.5 +Hsync / -Vsync

I'll try it out as soon as I hear if the nouveau driver is using
modeline in xorg.conf or not.

Aside. I'm using the KDE display tool in Settings-System-Settings. It
doesn't display as much information as nividia-settings, but it does
some things (monitor rotation, etc.) better.

What is interesting to me is that I get a different horizontal
resolution (1600 versus 1920) when I use the DVI adapter. That tells me
the video card is trying to do something different. Is the driver
supposed to sync up the card to the monitor in the absense of correct
modelines ?

BTW: I thought the 20 inch display on my HDX was high quality. The
U3011 (running 1920x1600 in 1:1 display mode) blows it away. Its almost
too sharp and bright. But that can be adjusted. The HDX display looks
like trash now. Dull, faded and fuzzy.

Its really interesting that you said that because it prodded me to look
at the output for nouveau and I found its very verbose in this regard.
Much better than the nvidia driver.

Here is a pertinent snippet. None of the EDID info goes past 1920x1200,
which is the maximum resolution that I am attaining. This was run with
the monitor connected to the HDMI port, which Dell says has a limit
of... 1920x1200.

I'll connect to the DVI port and rerun it.

Here is the snippet when connected to the DVI port with the dual link
adapter. The highest resolution found is 1600x1200, which is what I
attain.

I am confused about what is obtained by probing and what is obtained
from EDID data.

Nevertheless, there is no 2560x1600 mode appearing.

Is this a bug in the Dell EDID data ? The nvidia-setting application
had the option to open an EDID file, which I did not pursue.

Any and all advice on how to proceed from here, ie exactly what to put
in the xorg.conf file to tell the driver to ignore EDID and probings and
use a modeline directly, will be appreciated.

Kudos to the nouveau people for putting this much information in the log
file.

Thanks !

BTW, PixClock max 285 MHz is quite a bit less than the maximum pixel
rate for HDMI 1.3, which is probably what the card in the HDX puts out.

I have had similar difficulty getting a Dell U3011 to run at 2560x1600
on a MacMini with an Nvidia GeForce 320M. Using the displayport
interface on both the 320M and the U3011, the best I can get is
1920x1440. I did play with the xorg.conf file quite extensively, but
didn't do any better trying to specify modelines. I am using the Nvidia
driver.

I also had difficulty trying to get a second monitor to work. The
second monitor is a Dell U2410. I can get either monitor to work fine
alone, but when I try to start the xserver with 2 monitors connected,
the second monitor can't sync. The second monitor (U2410) is connected
to the HDMI port.

I just found this in the log file.
