Using those options should not be necessary. The driver is still invalidating your mode but you're telling the driver to just use it anyway.

So why am I seeing the same behavior in 100.14.19? Or are we confused as to what that bug was addressing?

I'm pretty sure I've tried every released driver version, and the EDID mode for 1080i works fine in 8776, but has the problem described above in every driver since.

I've also been unable to get any manual modeline for 1080i to work with any driver. They all display a black screen. (I've tried pretty much every modeline posted in the several 1080i-related threads here.)

At this point, the only working 1080i solution seems to be the EDID mode with the 8776 driver.

Bug 309982 was opened to address the problem where an interlaced native mode was rejected by the driver because its VertRefresh was erroneously detected to be out of the range specified in the EDID (120.1Hz rejected because 59-61Hz was defined).

Ahh, thanks. Are you tracking the bug where the 1080i mode from EDID is displaying only the top half of the image as I've described above?

No, I don't believe that problem has been reproduced.

Perhaps its just me, but when I did get the 1080i mode to display and seen that the vertical resolution was stretched as you describe, I assumed this was a bi-product of having told the driver to ignore so many things in order to make it work.

In addition to problem be related to interlaced modes, I wonder if this only occurs on TV's that do the 540 upconvert to achieve 1080i? At least all the debug logs I've read the resolutions where 1920x540, but that doesn't mean it is.

As far as I can see this bug still exists in 100.14.19.

Default Re: 1080i EDID modes broken in 100.14.19

Minor update: I've confirmed that this behaves exactly the same way when using a simpler mode validation line:
Code:
	Option		"ModeValidation" "NoVertRefreshCheck"
Without "NovertRefreshCheck" the driver gets confused on the refresh rates for interlaced modes:
Code:
(WW) NVIDIA(0):     Mode is rejected: VertRefresh (120.0 Hz) out of range
...
(WW) NVIDIA(0):     Mode is rejected: VertRefresh (120.1 Hz) out of range
The other interesting thing that I note is that xrandr reports that there are two 1920x1080 modes, one at 60Hz, and one at 120Hz. It seems to do that for all interlaced modes. It's the 120Hz mode that has the wrong display. Selecting the 60Hz mode seems to put it in my odd 1152x672 mode (the first, and therefore default mode).

Here's a thought. I see in the documentation:
http://us.download.nvidia.com/XFree8...DME/README.txt
There's a option, "CustomEDID" to let you grab the EDID information from a file instead of from the monitor. While this normally would seem useless, it could be great for debugging. Is there some way to grab that and include it in a bug report? (At least some of the EDID is included in the log file already.)

It seems that we may have several semi-related bugs here (all from 100.14.19):
  1. Using a valid 1080i EDID mode displays incorrectly (the top half fills the whole screen)
  2. Interlaced modes are treated as having double the refresh rate, breaking mode validation without an override.
  3. Interlaced modes are reported twice by xrandr, once at the doubled frequency, and once at the right frequency.
I'm also unable to get custom 1080i modelines to work, or even to display the stretched image like the EDID mode. I suspect that's an artifact of some of the above factors.

If there's anything more that I can do to help get these bugs fixed, please let me know.

Was there ever a bug logged on the issue or is there anything futher that we need to do so that it does get logged? If it is logged then what else can be done? Do more people need to confirm it is an issue for them?

I have confidence that this a bug for the simple reason that I can drive the same TV using the same hardware & cable at 1080i resolution, but with an aged ATI 9800pro.

I can verify that the "NoVertRefreshCheck" mode validation option is still required to avoid rejecting the 1080i modes for having 120Hz refresh rates in 100.14.23 (the latest beta version of the driver at this time).

What type of logs/data do you need? This is happening to me as well, and I'm happy to post anything needed to resolve this PITA issue.

yes, same. Any info required I'll dig up to get 1080i working correctly.
