DVI to HDMI Nvidia Overscan

[deanjo]

By that logic, Microsoft would be responsible for providing the overscan adjustment tool for Windows, but in fact both Nvidia and AMD/ATI provide it instead.

Adjustment isn't needed in windows when the EDID isn't broken. Window also allows you to use the driver disk that has the scanline info.

Besides, even if I accepted you logic, it would only hold true if the Nvidia driver was open source. But the Nvidia binary drivers are incompatible with the X display settings gui. (At least the one supplied with Ubuntu 9.04), and forces you to use the Nvidia supplied X settings program instead. So I would say that Nvidia has clearly occupied that territory and has made the settings very vendor specific at least as far as a front end is concerned.

Find a better distro with better setup apps. SaX2 for openSUSE for example generates the xorg just fine for nvidia cards. See:

None of that was generated with nvidia settings.

Mind you, I am very happy with the Nvidia driver performance, and extremely happy with VDPAU. That is why I switched from AMD/ATI to Nvidia in the first place. I just do not understand why you would take a position that leaving out a useful feature is defensible for any reason other than that it is a simple oversight, or that they have just not gotten around to it yet.

It's not that it's a oversite, it's that there are tools out there that already do these tasks. SaX2 for example can use the windows .inf file for inputing the correct mode lines, adjust the screen size and position, enable dual head, etc etc. If it's really anyone's over sight it is your distribution that fails at supplying you with the tools to do so.

Adjustment isn't needed in windows when the EDID isn't broken. Window also allows you to use the driver disk that has the scanline info.

Find a better distro with better setup apps. SaX2 for openSUSE for example generates the xorg just fine for nvidia cards. See:

Now you are coming across as arrogant. Whether or not that is intended I really can not tell. Nothing in your xorg.conf is making an adjustment for overscan, so you don't seem to have a system that suffers from this issue. A quick google search for 'suse nvidia overscan' will reveal to you that there are in fact people using your favorite distro that also have had trouble figuring this out. I have fixed this problem on my Ubuntu system, so I've got no problem continuing to use said distro. Statements like 'use a better distro', and your earlier statement (paraphrased) 'get a TV that isn't broken' make it clear to me that continuing this discourse is a waste of time. Have a nice day.

The same monitor has a broken EDID when using the HDMI interface. Same situation as yours. On the other system ignore EDID is enabled and that was all done via SaX2. So yes I do suffer the exact same issue. The posted Xorg was to prove to you that "forces you to use the Nvidia supplied X settings program instead" is pure bullshit. BTW every feature in the nvidia drivers can be enabled / disabled / or set value too. People post all the time as well no matter what os / card / driver / etc as some people especially n00bs find it easier to ask then to look on their own despite the answer being often right under their nose.

BTW: Will gladly post screen shots of SaX if you wish after I get back from work today. Also why do you think XBMC can handle overscan issues through their app and how can it do this? Oh ya, because they wrote in the capability of doing this.

[lbcoder]

So you blame nvidia for not fixing your broken EDID on your TV? Sorry but no driver can fix that. When your correcting overscan in the windows drivers your adjusting modelines as well. You have the same capability in linux which is handled by xorg.conf. Place blame where blame is due.

Are you on crack or something? Who said I had any problems with overscan. I don't even own any nvidia garbage any more.

Ok, I really wanted to end this, but the voice inside my head is screaming to get out. XBMC doesn't change anything in the modelines in xorg.conf, or change the resolution on the screen at all. It just scales itself to use the smaller portion of the screen. It can not, for instance, deal with the opposite problem of having a black border around the outer edge due to underscan. In either case, I think we should just agree to disagree at this point. I believe that hardware manufacturers providing a binary driver and software application to control that driver should strive for feature parity between platforms, and currently the gpu vendors are not doing that. You don't seem to agree. All the other arguments on both sides aren't going to change either one of our minds. I've got nothing against Suse, but I am happy with Ubuntu and don't see a need to change. I'm not about to get into a distro argument. Maybe I'll check out Suse again on a spare system someday. I'm sure I've have it installed at some time in the past. I just can't remember. I don't consider myself a nOOb by any stretch, but neither am I a guru. I fall somewhere in between. I first used Linux nearly 16 years ago but never used it as a primary OS until about 2 years ago when I built my first HTPC. I don't really enjoy screwing around with my system that much. I enjoy using it.
