Question LCD TV not recognized as DFP / no DVI / MSI GeForce FX5200

I'm unable to convince my MSI GeForce FX 5200 graphics card to emit a digital signal to my 27" LCD TV screen.

The Medion LCD TV has a DVI-I inlet and is specified to support a number of standard resolutions like 640x480 and 800x600 up to its native resolution of 1280x720, both for analog and digital signals.

The LCD TV is connected via a DVI-I cable (18+5 pins) to the DVI-I outlet of the MSI graphics board. I tried configuring the LCD TV to expect only digital, only analog or "autodetect" either on the DVI-I inlet, but that didn't make any difference. The second, analog VGA outlet and the TV-outlet of the MSI board are unconnected. I also tried to use a "digital-only" DVI cable (18 pins), but that didn't help, I was just getting no picture at all, using that cable.

At boot time, the screen shows the BIOS messages, detecting an analog signal (640x480-60Hz) - unless the LCD TV is configured to expect only digital signals, in which case the no signal is detected.

I wouldn't mind getting the boot messages only "in analog", but what is of great importance to me is the ability to activate the digital output, later - for the X display, because the analog signal is not pixel-exactly synchronized, so e.g. black characters on white look a little "blurred", some stems are thicker, some thinner - a problem that can surely be solved by using a digital connection.

I read through all the READMEs etc. and tried various configuration options in the XF86Config, especially 'ConnectedMonitor "DFP" ', I tried ignoring EDIDs and so on, but nothing seems to cause a digital signal to be emitted. I've tried both the latest "1.0-6629 for Linux x86-64" driver and the open-source "nv" driver that came with XFree86.

Some READMEs seem to indicate that the drivers won't be able to activate DFP output if the graphics board didn't activate it during boot POST. That may very well be my problem, but how am I supposed to fix that? Is there any method to influence the behaviour of the graphics board at boot-time?

BTW: Before you suspect that either my LCD TV or the graphics board are simply broken, consider this: I connected an HP LCD Monitor to the DVI outlet, booted, the HP LCD instantly got a digital signal, started X11, then I disconnected the HP LCD (yes, I know, it's not a good habit to do so while power is on) and connected the LCD TV and - voila - there was a digital signal detected by the LCD TV and displayed. But on the very next occasion when I stopped the X-server, the digital output became silent again. Of course it is not really an option to me to switch between those monitors everytime I startup X...

So after all it seems that for some reason the MSI GeForce FX 5200 board thinks the LCD TV is not a digital display, and thus does not activate the DVI outlet.

Is there any way to force the digital output to be activated?

What may keep the graphics board from believing in the existence of a DFP?

Logs and config files would be a start....

Well, here's the relevant excerpt of a XF86Config I tried (among many others, but this one should be working and does work if at boot time a differenc LCD monitor was connected):

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "0"
HorizSync 31.5 - 64.0
VertRefresh 58.0 - 62.0
ModeLine "720p" 74.2 1280 1352 1432 1648 720 725 730 750
Option "nodpms"
Option "NoDDC"
EndSection

Section "Device"
Identifier "nvidia0"
Driver "nvidia"
EndSection

Section "Screen"
Option "ConnectedMonitor" "DFP"
Identifier "Screen0"
Device "nvidia0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Modes "800x600" "720p"
Depth 24
EndSubSection
EndSection

... and here's the log resulting from this config (the forum does not allow me to post the whole log, it displays: "The text that you have entered is too long (18059 characters). Please shorten it to 15000 characters long" if I try, so I had to shorten seemingly irrelevant parts, substituted by "..."):

However, the most important question to me seems to be: Is it true that nvidia drivers - whether the open or the closed source ones - won't be able to drive a flatpanel display if that display wasn't recognized as such by the graphics board at boot time?

If the answer to that question is "yes" (as one may conclude from some REAMEs), then all efforts to change the config or looking at the logs will be futile...

Or asked the other way round: Is there anybody who has succeeded in driving a flat-panel digitally from a nvidia card that was _not_ recognized at boot time...?

Default Re: LCD TV not recognized as DFP / no DVI / MSI GeForce FX5200

BTW: The release notes of the Windows 67.02 beta drivers mention among others the folloging new features:

- Added support for using HDTV over DVI connectors
- DVI hotplug

Sounds a little like those features could be important for my problem, too... does anyone know how long it usually takes until nvidia ports windows drivers to Linux?

You can just attach files, this way we're sure that we get everything and it's MUCH easier to read.
Code:
 SubSection "Display"
Modes "800x600" "720p"
Depth 24
EndSubSection
This means that it will use "800x600" as default, try switching them around.

Though the LCD's manual states that 800x600 is among the supported modes on the DVI inlet, I tried switching those mode entries - but that didn't make a difference.

Have you tried with the special hdtv modes?

Special HDTV modes?

My understanding so far was that the only HDTV-specific treatment could be applied to the (s-video) TV-outlet which I am not using - but maybe that was a misunderstanding... what Options would you propose?

Unhappy Re: LCD TV not recognized as DFP / no DVI / MSI GeForce FX5200

I read a little about those "special HDTV modes", they are really only for analog TV-Out.

So I'm still stuck with a card that would be able to drive my DVI display but does not only because it is unable to detect at boot time there really is a DFP connected...

Some READMEs seem to indicate that the drivers won't be able to activate DFP output if the graphics board didn't activate it during boot POST. That may very well be my problem, but how am I supposed to fix that? Is there any method to influence the behaviour of the graphics board at boot-time?
I just assembled a PC running FC3 and I am experiencing this same problem. No DVI output at boot time or when X starts. I am using an FX 5500 with a Syntax Olevia 27" LCD TV.

When will we see a fix for this problem, Nvidia? Is it a driver issue or a video card firmware issue?

Thanks
