Sharp Aquos & 9800GT cuts off ~10mm around the edge

[nuudles]

The monitor is a Sharp Aquos 37" 1080p connected to a EVGA GeForce 9800GT. I installed driver version 180.11 using the repositories in Ubuntu and it seems to work beautifully in every facet other than how it crops the edge of my screen. When I first installed the driver it came up at 640x480 and showed the entire screen, but I get my problem after running nvidia-xconfig and letting it choose what to do.

This looks to me like it's loaded the driver but when X starts I don't get the nVidia splash screen, but all of my 2d & 3d acceleration works, and the nvidia-settings tool recognizes everything as it should.

Could this be a problem with the DPI that the driver has picked? The log says 75x75, but unfortunately I can't seem to find any documentation for my TV that shows what it's DPI is supposed to be so I've just left that as is. The model is LC37D64U just in case anyone out there happens to know about or own this screen.

Any ideas would be appreciated at this point, I've tried 3 different binary drivers from the repositories. Installed 5 different versions using the manual installer, reinstalled Ubuntu 8.04 & 8.10 at least twice each, and even briefly considered installing Vista just to reap the full benefits of the card.

I forgot to add my xorg.conf, here's the relevant portions, the modeline I've added I got from the logs after running X with -logverbose 6.

This is probably due to overscan on the TV. Check the menus to see if it is possible to switch this off. Under picture format there is possibly a choice called exact scan or something similar.

View Mode => dot-by-dot is what I do on my Aquos.

Hi, and thanks for the replies.

jpterj, I couldn't find any setting for over scan, or any other setting that helped at all.

bin2gray, would you mind elaborating on your meaning for 'View Mode => dot-by-dot'?

He is probably referring to the menu on the TV. I guess that under 'View Mode' there is a choice called 'dot-by-dot' which turns off overscan.

I'm still having this problem, I even went and bought an 8500 GTS and I'm having the same problem. If anyone has any idea how to configure X to get this monitor going I would be very grateful for your help.

On remote controller it's the same button as for changeing aspect ratio, eg. 4:3, 16:9, 16:10, zoom, film, etc...


Thought I have Aquos LC-32X20E here is my remote and "Wide Mode" screen:

That is because the problem is in your TV, not in the card or the driver.
You need to find out how to turn off the overscan in the TV.

I didn't realize that I never came back here to say that the dot-by-dot setting was in fact the issue. Once I found the view mode button on the remote control the problem was solved.
