<SOLVED> New video card unable to match screen size properly...

[hundin]

and I am getting quite the headache.  Just bought a Galaxy GeForce GT 520 1024MB DDR3 card for my desktop.  I have a Sylvania LCD 23" as a monitor.  At FXdrake, I selected NVIDIA GeForce 400 and later.  I then went with the default sttings, rebooted, and had a desktop.  The only problem is the desktop exceeds the edges of the monitor, by quite a bit from what i can tell.  I.e., My task bar only shows the top half, and when windows open, they open further than the top of the screen, making it a challenge to close.  Searching thru posts, i have surmised the following info to be useful...

Code:

[hundin@localhost ~]$ xrandr -q

hundin> I am no expert but it does appear that the monitor resolution is not properly set.

Here's mine:

In PCC>Configure Video Card can you set the correct monitor and resolution?

Others may be along to give suggestions but that is where I would start.

[kjpetrie]

Open PCC Hardware -> Configure Video card and set the monitor to the correct model or to the correct resolution (as given in the specification of your monitor), then set the display to the correct resolution. 1024 x 600 is clearly wrong for such a large screen.

You don't say how you connect to the monitor. Some monitors have an 'overscan' setting where they enlarge the image to overlap the edges and you might need to check that setting on the monitor itself if it has one,

[Just18]

If you have thisproduct

SYLVANIA 6632LG (32" LCD TV)

then the native resolution is

1366 x 768

and that is what you need to use in the setup.

I would also have thought that the driver for your card would be the

6100 and later nvidia driver.

You should ensure you add the following option to you boot line in menu.lst file for best results

vmalloc=256M

[hundin]

just18, it was your suggestion of using 6100 and later nvidia driver that did the trick.  After selecting it, I was able to use the Nvidia Display settings gui, which had an aspect ratio slidebar.  Viola, edge to edge desktop!  Thanks for looking into my little slice of confusion, I do appreciate all the help.
