You can use nvidia-settings to get your EDID info. Run nvidia-settings, click
on DFP-0, then click "Acquire EDID..."
Store the file to television-edid.bin
Install the package edid-decode and do
edid-decode television-edid.bin
This gives the following output:
...
First detailed timing is preferred timing
Established timings supported:
720x400@70Hz
640x480@60Hz
640x480@67Hz
640x480@72Hz
640x480@75Hz
800x600@56Hz
800x600@60Hz
800x600@72Hz

832x624@75Hz
1024x768@60Hz
1024x768@70Hz
1024x768@75Hz
Standard timings supported:
Detailed mode: Clock 74.250 MHz, 708 mm x 398 mm
1280 1720 1760 1980 hborder 0
720 725 730 750 vborder 0
+hsync +vsync
Monitor ranges: 56-76HZ vertical, 31-61kHz horizontal, max dotclock 80MHz
...
Thus the television says it can do 1024x768@75Hz, and it is not NVIDIAS
fault that it gets such a signal that it cannot display well when
switching to 1024x768.

Title:
After upgrading to 14.04, nvidia-settings crashes with "BadValue" X
Window System error
Status in “nvidia-settings” package in Ubuntu:
New
Bug description:
After upgrading to 14.04 the screen resolution is not as I want and
changing with nvidia-settings is not possible, because the program
crashes when applying new settings.
michael@quad:~$ nvidia-settings
ERROR: Error querying target relations
The program 'nvidia-settings' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 738 error_code 2 request_code 158 minor_code 25)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

The crash occurs when using the "Apply" button.
