I'm an HDTV user and I send 1080i to my set over a VGA cable. Nvidia screwed up their drivers after 6629 for 1080i output -- the screen was folded in half with the right and left halves swapped. This includes the standard 7174 driver used in R5B7.

I am happy to report that the latest nvidia driver, 8178, works just fine with 1080i signals over VGA. It's easy to install using the included script on KnoppMyth. First swtich to a shell (using ctl-alt-F1) and log in as root. Then execute the command:



Don't forget to DISable the "vblank on OpenGL" option for the nvidia driver using nvidia-settings. The new 8178 driver is working very well in my tests so far.

I will try this tomorrow, probably. Thanks for posting this.
What's the easy way to "roll-back" (to the default one with R5B7), if I get into trouble? Do I do an install-nvidia-debian.sh with the older version?

I'm hoping that this driver will help me get to real 1080i. My TV reports back as 540, and so far, any attempts to override result in an unreadable, but high-res, result looking like every other scan line is reversed, and the whole thing jitters. I made some modelines using my Windoze PC (also has DVI, but with a different nVidia card) and that worked - I was able to see and use 1920x1080 on XP, but I've been thwarted so far, on the KnoppMyth box.

Yes. Just use the keyword "1.0-7174" for the original version.


You're welcome to try my modeline. No guarantees, of course, but it works well on my Pioneer PRO-610HD using VGA.

Thanks and Thanks.
The fact that you don't need "IgnoreEDID" makes me think that I'm going to have a tougher time. I think my TV just misses the boat on the whole deal about being hooked to a PC. In fact it says so in the manual, when discussing the DVI port.

My TV did require the ignoreedid line, but worked fine with 1080i and the latest nvidia drivers. Even popped up and said 1080i source.

Experimented last night, made some progress, but still not there yet.
Lots of my modelines are kicking out in the log due to having this or that not being a "multiple of 8". This includes my modeline that I made with PowerStrip with my Windows PC. Grrr... I read somewhere that nVidia is working on drivers that won't have the "8" requirement.
Then I started having trouble with the virtual desktop being huge, and the screen reverting to 540x960. I'd get a "pan" effect in Fluxbox, Myth sort of looked the right size but with small fonts, and playback was 1/4 of the picture. i.e. I'd see the upper-left quarter of Jay Leno's stage. Hmmm...
No flicker though.
I think it was giving me a virtual screen of 1920x1080, but only a physical 960x540 screen. Bummer.

I DID have partial success with that probably was a 1024x768 modeline. Seemed to be 700+ lines, but I had several modelines active and have to go back and see what it was. I saved that one, so I can go back and check it out. That was right before I had trouble with the virtual size.
I played around for an hour or so then commented out the ignoreEDID and went to bed (i.e. back to normal).

This morning I'm having trouble with 720p playback (ABC/FOX). It'll play a couple secs then pause, then I do a skip and it'll give a few more secs. Unfortunately, I wasn't very systematic, so I don't know if it's a problem caused by my tinkering with the modelines or not. I'll restore my original modelines this evening and give it a try.

I had no luck with the Ctrl Alt + and Ctrl Alt - keys (RF keyboard) to cycle through the modelines. i.e. if I had 4 modelines active, it should let me cycle through them, right? It wasn't.

thornsoft, I notice from your post that you are using the DVI connector. Some HDTV's, like my samsung, will not support 1080i via the DVI port. It will support 1080i across the VGA connector. This is not documented in my user manual, but I found this info in one of the forums.

Thornsoft,

There are some divisible by 8 modelines on the wiki:

http://www.knoppmythwiki.org/index.php?page=XModLines

What kind of TV do you have?

Rich

I'll try those, if I haven't already. I've got a SONY KP65WV700
It's a CRT RPTV, kind of at their high-end, but not in the XBR/WEGA range.
It's got DVI and Component inputs, but no VGA. Probably due to its age - MFG in Sept 2002.

I can run my stand-alone STB (LG LST-4200a) and I THINK I'm getting 1080i out of it, but for all I know, the two boxes may negotiate and settle for 540P.

I did, I did, I swear, get true 1920x1080 and 1280x720 from my XP box via DVI. But the 1920x1080 was a little shaky. A blank WinWord document would look ok, but if there was lots of text, it'll waver a bit. The 1280x720 looked pretty solid though.

Maybe my TV just isn't up to the job. It looks pretty great where I am, for just watching TV. But I'm having to run the Bob de-interlacer, otherwise I get wavy vertical lines when there is horizontal movement. I'm hoping that going to native 1080i would let me skip that, and I'd get less stuttering when I start/stop/skip.

Hi Marc,
This may be the case here. I don't have VGA in, so would it perhaps be worth it to try a vga/component converter? Hmmm...

Like this: 9A60 VGA Converter
http://mythic.tv/product_info.php?cPath=21_22&products_id=30

So can anyone who has there HD working post the modeline and type of tv/input they are using.

I'm using:

TV: Sony 46" KP-46WT500
Input: DVI
Vid Card: nvidia 6200
Modeline: Can't get one to work (((

I've been trying for months but just end up giving up. I've tried the powerstrip etc...and no luck. I'm to the point where I might go out and buy a new tv ..hahah

I hope you don't mind this minor thread hijack, but does one need to uninstall
the old nvidia driver before installing a new one? I couldn't find this
information anywhere.


Thanks


Shplad

No need to "uninstall" before installing the new one. At most, you may have to stop the X server with:

But from my recollection, the install script does this for you as well.

Update: I just rolled back to 7676, as I have been having daily lock-ups. Hopefully that'll help.
install-nvidia-debian.sh 1.0-7676 -force

If you're trying to get the 1080i output thru DVI, you are out of luck...for now anyway. It's possible to get 1080i thru VGA, but not DVI. There's a lengthy thread in this forum for the 8174 drivers that touches on it. Nothing has changed 1080i/DVI wise with 8178.
