I'm new to linux and so far my understanding to adjust the resolution for your monitor is done via the xorg.conf. I have tried to edit this by inserting a modeline of 1366*768 but i get stopped on boot up and have to copy the backup file back to the xorg.conf to resume using the computer. I realize now it isn't just a matter of just changing the resolution so this is where I need some help. I have tried to find out the necessary info by google and irc but have only gotten a taste of what it takes to get this done.
I have a Westinghouse W4207 42" LCD HD monitor (they have nothing on their site for modeline info) and a NVidia 7300 le video card. This setup works great under windows and it has worked in linux too but I don't have that setup to reference.
If I could get some info on what the modeline variables are or find a setup that explains what the variables are, I would have a very good start at completing this.
Thanks

Do you still have the Westinghouse manual (or can you download a PDF from their website)? It may have info that will help you make a valid modeline.
Barring that, if you say you've gotten things to work via Windows, you could use Entech's PowerStrip to export a modeline that should give you the same video settings under X.org. (Entech's website also has a database of modelines that might help.)
I'll note that it's probably not possible to get exactly 1366x768: I think the Nvidia drivers only allow resolutions evenly divisible by 8, so you'd either have to use 1360 or 1368. If you just want to get things working, you might also try a 1280x720 modeline first, then fool around from there to try to get closer to the native resolution of the screen.

Thanks for your reply!
I found something already that you also suggested in your reference material.
http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
This is a modeline generator. I have my manual for the tv and came up with a modeline that I will try tonight. Hopefully that will work.
Thanks

Not sure how Westinghouse handles it, but I know the Vizio displays wanted you to set your res to 1024x768 when using the VGA port. You should be able to set it to a normal resolution and let the tv convert it. It's doing that for all your other stuff, anyways.

If the 1366x768 is your monitor's native resolution, you can add
Code: nvidia-auto-select
to your Screen section of xorg.conf. It will select the "best" (and in my experience) the highest resolution your monitor's EDID reports to the NVIDIA driver. For example: Code: SubSection "Display" Depth 24 Modes "nvidia-auto-select" "ATSC-1080-59.94i" "ATSC-720-60p"

I tried your method and it worked better. I could only get 1360*768 using the modeline generator, with your method I got 1366*768.
Thanks

I have the exact same Westinghouse TV (Black Friday special), and found your post at the Ubuntu Forums, http://ubuntuforums.org/showthread.php?t=364252#8, which specifies how to set up EDID. It worked, and seemed a great deal easier than anything else I'd seen:
williammanda wrote: Re: Help Fixing overscan on HDTV FWIW I have found to get the native resolution for my monitor is to have it probed by nvidia. This setup works best so far across many debian setups I have tried. I have a westinghouse 42" lcd native 1366 x 768 and the best I can get is 1360 x 765. I will use the prior posted xorg.conf file as an example Code: Section "Monitor" Identifier "SONY TV" #HorizSync 15.0 - 46.0 #VertRefresh 59.0 - 61.0 #Option "DPMS" #Option "IgnoreEDID" Option "UseEDID" "True" #DisplaySize 720 405 #ModeLine "1280x720@60" 74.48 1280 1336 1472 1664 720 721 724 746 -hsync +vsync #ModeLine "1216x648@60" 74.48 1216 1272 1400 1664 684 685 688 746 -hsync +vsync EndSection
Section "Device" Identifier "NVIDIA Corporation NV18 [GeForce4 MX 440 AGP 8x]" Driver "nvidia" EndSection
Section "Screen" Identifier "Default Screen" Device "NVIDIA Corporation NV18 [GeForce4 MX 440 AGP 8x]" Monitor "SONY TV" #Option "FlatPanelProperties" "scaling = centered" DefaultDepth 24 SubSection "Display" Depth 24 Modes "nvidia-auto-select" EndSubSection EndSection
Let me know how it works out. Thanks
That is easily the first method I'd recommend to anyone trying to get 1366x768 to their TV.

well it's been ages since I've tweaked my mythBox! Recently got a M2NPV-VM and a 500G drive and I thought I'd start from scratch.
So I've been trying to get my old modeline (which worked great) working on the new xorg.conf file. No joy yet. I'm going on 3 days now.
Here's the modeline which used to work on my a8n:
Code: Modeline "1368x768" 85.86 1368 1440 1584 1800 768 769 772 795 -hsync -vsync
Here is a portion of my xorg.conf: Code: Section "Monitor" Identifier "Monitor0" Option "DPMS" "true" Option "UseEDID" "FALSE" Option "DPI" "100 x 100"
#loads of modelines. . .then mine:
Modeline "1368x768" 85.86 1368 1440 1584 1800 768 769 772 795 -hsync -vsync EndSection
#other stuff, then screen section: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultColorDepth 24 SubSection "Display" Depth 1 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 4 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 8 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 15 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 16 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 24 Modes "1368x768" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 32 Modes "1368x768" "1024x768" "800x600" "640x480" EndSubSection EndSection
Now comes the aggravation of the /var/log/Xorg.0.log: Code: (**) NVIDIA(0): Option "UseEDID" "FALSE" (**) NVIDIA(0): Option "DPI" "100 x 100" (**) NVIDIA(0): Enabling RENDER acceleration (**) NVIDIA(0): Ignoring EDIDs (II) NVIDIA(0): Not probing EDID on DFP-0.

(WW) NVIDIA(0): Unable to use mode "640x480" for DFP-0; cannot compute backend (WW) NVIDIA(0): DFP timings (no EDID).
#long list of un-useable modelines... then

No, I don't.
#a bunch of resource ranges, then:
(II) NVIDIA(0): Setting mode "nvidia-auto-select"
then some other non-pertinent stuff. So, my display is stuck at 800 x 600. I've tried EDID "TRUE" and "FALSE" and I also tried DPMS "TRUE" and "FALSE" When I try EDID "TRUE" I can get 1024x768 but the 1368x768 never budges from Code: No valid modes for "1368x768"; removing.
Also, note that I'm not using the "nvidia-auto-select" option in the screen section at all but it still seems to be there. When I do use it, I get 1024x768 and the same 'No valid modes for "1368x768" message.
TIA

Post your xorg.0.log after changing EDID = true and remove the dpi 100 * 100.
Thanks

I REALLY appreciate the input! If I can't figure out what's going on with this by sunday, I'm going back to R5C7.

Hey! I'm liking the sound of that "xorg 7.1" hmmm... Thanks, I hadn't seen the new release.

Change the following:
SubSection "Display"
Depth 24
Modes "1360x765" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 32
Modes "1360x765" "1024x768" "800x600" "640x480"
EndSubSection
It seems to be having trouble setting the exact resolution, so sometimes it is easier to give it something it can setup.
Thanks
