For about the past week I have been trying to build a HDTV modeline for my new frontend with not much luck :cry:

TV- Hitachi 43UWX10B - RPTV Supports only 1080i/540p, 480i
Motherboard Gigabyte GA-K8N51PVMT-9
Athlon 64 3700+
2GB Patriot DDR Ram
Onboard Nvidia 6150 with component out dongle adapter

The machine works fine as a diskless frontend with S Video and plays back CSI Miami HD perfectly. I setup another drive with Powerstrip and created a 540p modeline that works in Windows. Monifo doesn't work on my TV because it doesn't support EDID.

Next I upgraded the NVIDIA driver to 1.0-9639 because I understand there's a Nvidia 1080i bug in the driver that's in R5F1.

Here is the relivant portion of xorg.conf, I edited Xorg.conf to try an isolate the problem down to the bare minimum.

Code:
Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Hitachi"
    ModelName      "43UWX10B"
    HorizSync       33.0 - 34.0 # Extreme conservative
    VertRefresh     59.0 - 61.0 # Extreme conservative
#My 540P Test Modeline
#   Modeline "856x480p" 37.932 856 968 1016 1112 480 524 525 569 +hsync +vsync
#   Modeline "864x486p" 32.901 864 888 976 1088 486 487 490 504 +hsync +vsync    
#   Modeline "960x540p" 42.16 960 1056 1104 1248 540 547 548 563 +hsync +vsync 
    ModeLine "960x540p" 37.26 960 976 1008 1104 540 542 548 563 +hsync +vsync   
    Option         "DPMS" "true"
    Option         "UseEdidDpi" "FALSE"
    Option         "DPI" "100 x 100"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Card0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option "TVStandard" "HD1080i"
    Option "MetaModes" "1920x1080"       

SubSection     "Display"
        Depth       24
        Modes       "960x540p" "1920x1080i"
    EndSubSection


I've read and reread the nvida docs but I'm not sure if Metamodes 1080i
will pass a 540p modeline correctly. I seem to always get a blank screen. Xorg.0.log is fine

(
Code:
II) Setting vga for screen 0.
(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32
(==) NVIDIA(0): RGB weight 888

Any ideas what's up with 540P using a straight component connection? :?:

tv out doesnt use modelines.

it contains a hard coded list of mode sizes that it can drive for each of it's tv standards.

I believe your problem is that 540p isnt a valid value for TVStandard in linux nvidia drivers.


in your tv standard section of your xorg.conf, you've selected HD1080i and your metamode is 1920x1080, so the validated mode is 1920x1080. any modelines you have quoted in or out arent been used.

if you'd set TVStandard to HD540p, it would default to NTSC

if you want to use modelines .. connect to your tv via a DVI-component adapter.. not directly through the tv out on the video card.

Thanks for the reply

My motherboard has onboard a connection that gives component out and it goes straight into component in on my television. The sample HDTV modelines do not work with my TV so I created a custom 540p modeline with powerstrip.

The way I understand it in priciple is that 1080i = 540p

Thus, your point is correct and the Nvidia Driver only lists support 480i, 720p, 1080i etc. it sees 540p as a 1080i mode line.

Taking it one step further I would like to see a Xorg.0.log pass a Virtual screen size say "960x540p". How to get the Nvidia driver to pass a custom virtual screen size is the next step i think.

yeah.. i should have started my reply with "dont take my word for it but i thought that..... "

anyway.. ive read heaps on contradicting things about the equivalency or otherwise of 1080i and 540p. .. which i find irritating. i once sent an email to nvidia asking them to flesh out the tv out section of their readme file ...sorry i can't answer your question. please post if you figure it out.

i think i write in saying that the custom modelines are not been looked at by the driver. and that the as youre connected via a tv, the "mode" section of you xorg.conf isn't been looked at. The virtual screen size is been set to 1920x1080 because that is what you have set the metamode to. I'd try setting the metamode to "960x540" ... (dont include the "p"). if it's a valid mode, it will set your tv to that... if it isn't.. Xorg.0.conf should say that your resolution is set to its default...

this is my favorate post for tv out.

I have the same motherboard, and am trying to get it to work with a Panasonic HDTV using the component connection also. So far I have been able to get the knoppmyth interface to work, but it I try to watch anything I just get a black screen that I cannot get out of.

I am having the same problem with 1080i myth GUI to work fine, but when I watch live TV, it goes to a black screen I cannot get out of.

I have a successful install with my Pioneer PRO-610HD rear-projection TV. I connect to it with a VGA connector. Here is the interlaced modeline I use:

Code:
ModeLine       "ATSC-1080-59.94i" 74.2 1920 1960 2016 2200 1080 1082 1088 1125 interlace


I have joined in the debates about whether 1080i == 540p. I don't think it does, but I could be wrong. Since the card supports interlace, I figure I'm providing more information to the rendering software by including an interlace modeline.

The above modeline has worked for me in all versions of KM for about three years. My set doesn't support any HD mode other than 1080i, so this is my only modeline in xorg.conf. (It could support 480i/p but I'm not interested in setting up RandR to make it work. Myth just scales it for me if I'm watching an SD show.)

Hi Guys,

I have a 6150 board and I am using the component dongle to output to my HDTV at 1080i. The system locks up and shows black when playing video if you do NOT turn off the "Video texture adapter" "sync to vblank" option. This option is on the second page of the "nvidia-settings" program. This program can be accessed in apps->tools-> menu from desktop.

However, I am also struggling with this setup using R5F27 because it only plays back 720p properly in 1080i. If I try to playback 1080i in 1080i it occasionally stutters for a 1/2 second or so. It doesn't sound that annoying, but it REALLY is.

Hope this helps,
Rick

Upgrading the nVidia driver to 9755 or 1.x will take care of the vsync black screen problem.

But you'll still have smoothness problems with 1080i output without bob deint. I have the Asus M2NPV-VM (6150 component out) and the best I could get was with linear deint until tld figured out a workaround to enable bob.
See this thread for more info:

http://www.avsforum.com/avs-vb/showthread.php?t=815492

There will always be workarounds for 1080i output mode until nVidia fixes it so you don't have to deinterlace with a 1080i display.
