Default correct resolution of LCD, but picture is outside

Hello,

i have this problem (Ubuntu 9.04)

In Windows 7 can be set resolution 1360x768 (native LCD TV), picture is perfect (picture stretched on entire surface):

http://img139.imageshack.us/i/img1743k.jpg/


after in Ubuntu is available only lower resolutions:

http://img141.imageshack.us/i/img1747h.jpg/

when I install hardware drivers, then offer this:
http://img268.imageshack.us/i/img1748j.jpg/
or this:
http://img98.imageshack.us/i/img1749h.jpg/

Even if is resolution set right, like this is picture outside TV.

I don't really understand the last sentence.
The other pictures show an 'Unknown' display. This is not good, because then the software cannot query the details of the display, and cannot set it up correctly.
Show us your /var/log/Xorg.0.log when the graphical interface is up.

I have a similar display here, that xorg simply does not detect. Therefore I have to manually configure it in /etc/X11/xorg.conf; then it works.
But let's see your log first.

When is applied native resolution 1360x768 in Windows 7 is picture perfectly stretched to screen (all is showed), but in Ubuntu is picture large - top and bottom bar is out of screen - see http://img98.imageshack.us/i/img1749h.jpg/

Default Re: correct resolution of LCD, but picture is outside

Looks like this is an overscan problem. Try to disable overscan on your TV.

Default Re: correct resolution of LCD, but picture is outside

See, the EDID data from the monitor are considered false.
(I haven't followed the more recent developments of xorg, but there was a time when one could simply instruct xorg to disregard it. Recently, I didn't manage to.)
In any case, now you might as well show the relevant parts of the log file, when you instruct the correct resolution in your xorg.conf. Chances are, that some virtual desktop is still larger than the real one, and then you can use the mouse to move it about.
Once the virtual desktop equals the real one, you have a chance to actually see the real content.
