[solved] Need help with resolution on HDTV being used as a monitor

This is a separate but sorta related problem to my previous post: https://bbs.archlinux.org/viewtopic.php?id=101770

I have a Sanyo HDTV and I'm using it as my computer Monitor. The desktop now shows up on the screen, but the position of the desktop is wrong. (tool bars are off screen) and the windows are really big.

The TV manual gives these settings for hooking up a computer:

1360x768 16:9 refresh 60hz horizontal freq: 47.71 vertical freq: 60

Thats resolution is not showing up as an option in nvidia x server settings.

I tried using xrandr to set up the TV's resolution by adding a new mode

xrandr --newmode "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync

xrandr --addmode default 1360x768_60.00

xrandr --output default --mode 1360x768_60.00

xrandr: Configure crtc 0 failed

It didn't work so I tried following another tutorial online and added a modeline to my xorg.cong

        Depth       24
    Modes      "1360x768_60.00"
    EndSubSection
EndSection

That did not work either and now I'm a bit lost on what to do to get my desktop to show up properly on the screen.

In windows 7 I had to use some weird settings to get it to work:

resolution: 1790x1012
DPI: 125%

Should I try using those settings?

Any help will be greatly appreciated.

Re: [solved] Need help with resolution on HDTV being used as a monitor

Couple of weeks ago I did have exactly the same issue, probably following the same steps that you've done. I spent hours looking in logs and different configs, however the issue was a simple re-setup of the HDTV.

Check the settings of your HDTV and double check that the zoom in  option is not enable.
I hope it helps

Re: [solved] Need help with resolution on HDTV being used as a monitor

Just noticed you have given the modeline the label 1360x768@60 while you reference it as 1360x768_60 in your screen section. Is this just a typo, or does it really say that in your config file? Could perhaps be the problem?

Thanks guys. I fixed my xorg.conf >< and messed with the pix shape settings on my tv and got it to work.

Re: [solved] Need help with resolution on HDTV being used as a monitor

I'm having the same exact problem with my HDTV

Running latest NVIDIA 256.44-2, it keeps defaulting to 1024x768. Sometimes my monitor will display 1260x768 but nvidia-settings still only shows 1024x768 as the highest resolution.

Did you end up using 1360x768_60 or 1360x768@60?

Can you post your xorg.conf?

And what is the command to get your output of:

1360x768_60.00 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync

Here is my xorg.conf in case it helps

Edit: I was able to get my resolution to 1280x768 using the xfree86 modeline generator http://xtiming.sourceforge.net/cgi-bin/xtiming.pl ( i put in 1360 but it defaults to 1280)
