Unhappy Why can't I get proper display on my 40" LCD TV?

I have the 177-82 nvidia installation given by Fedora 10 on a Phenom MB with 8 GB of memory and a Geforce 9500 GT video card. The video card has two dvi connections which allows for dual video
connections but OFCOURSE the software is only for Windows. NVidia certainly
supplies an excellent driver for my video, but I cannot figure how to make it
give me "DualView" that I can set up in Windows.

The NVidia Display settings offers "TwinView" and I assume that is the same, but
when I install two dvi connections (one to my 19" monitor, the other to my
Samsung 40" LCD 1080 i/p tv) it only sees the monitor as being connected. I had
made sure to reboot for the "TwinView"/"DualView" to actualize but nothing
happened. I do not understand why?

When I connect the tv to the dvi connection that the monitor is connected to I
am able to get a display on the tv but even though the tv automatically shifts
to 1920 x 1080 the display is only what I had originally set for the monitor. Of
course, the video card and nvidia now see I am using a different monitor and as
such allows me to reset the display (supposedly) to 1920 x 1080 but I see a
varied size display.

Games, movie players, audio players like xmms are displayed appropriately, but
the screen itself is more similar to something between 800 x 600 and 1024 x 768,
while browsers are very distorted. The browsers appear to look like they are
similar to 640 x 480 on a 19" monitor. Very large indeed. I am able to shrink
the web pages to a more appropriate size, but that does nothing to the actual

Someone in "LinuxQuestions.org told me FC10 does not have xorg.conf anymore and
that is somewhat further confusing for me. I did not actually install FC10 in
the way that it would totally eliminate FC9 because I did not want to lose
important information. Thus, I used the upgrade procedure offered to directly
upgrade from 9 to 10. As such, some FC9 software that was not upgraded would be
left functional and unchanged. Perhaps that is why I have xorg.conf in /etc/X11.
Is it possible that the person in linuxquestions.org was incorrect? On the other
hand, is the fact that I still have xorg.conf why the displays are not
functioning correctly?

Can anyone help me? I know it works beautifully in Windows, even with only one
dvi, because my neighbor has the exact same tv. Of course, he is only using
Windows and is using an ATI video card. Nevertheless, nvidia is supposed to be
fantastic in Linux and I am using a Geforce 9 card. So does anyone know what I need to do?
All help will be great appreciated.

I am so confused!!

Default Re: Why can't I get proper display on my 40" LCD TV?

Not sure this going to help...

I've a GeForce 9500 GT card with a DVI (DFPU-0) and a HDMI (DFPU-1) connection. I'm running Fedora 10, clean install. During debugging some other problem (intermittent blanking) I had a monitor connected through DVI and a HDTV through HDMI.

When starting x the monitor would be selected as the primary display. However, using nvidia-settings I was able to enable Twinview and set the modes for the TV through the GUI. 1920x1080 on the TV and 1680x1050 on the monitor.

Try "man nvidia-settings" to see the possible options and settings. It is possible to save the settings and restore them automatically everything when you start X.
