Hi xor

Your color coding only made the terminal commands and responses difficult to read.
Adding  Bold  and  Underline  tags was not helpful either.

Please use  code  tags for displaying this type of information.
They look like this:

that message was not for you!

English is not a universal language,

I wrote to guide those who experienced the same problem.

it was a good narrative reference.

we are; We are different cultures that perceive English with logic matching

please restore the message you deleted.

and don't look at the whole world from a single angle.

respect differences

tc@box:~$ sudo cvt 1360 768

There is 1 inch horizontal shift on the screen!
"cvt 1360 768" command generates incorrect frequency values!
How can I add the real frequency values to the system!?



Thx :)

Hi xor
Code: [Select]
tc@E310:~$ cvt --help

usage: cvt [-v|--verbose] [-r|--reduced] X Y [refresh]

 -v|--verbose : Warn about CVT standard adherance.
 -r|--reduced : Create a mode with reduced blanking (default: normal blanking).
            X : Desired horizontal resolution (multiple of 8, required).
            Y : Desired vertical resolution (required).
      refresh : Desired refresh rate (default: 60.0Hz).

Calculates VESA CVT (Coordinated Video Timing) modelines for use with X.
tc@E310:~$

Is this what you are looking for:
Code: [Select]
tc@E310:~$ cvt -r 1360 768
# 1360x768 59.96 Hz (CVT) hsync: 47.37 kHz; pclk: 72.00 MHz
Modeline "1360x768R"   72.00  1360 1408 1440 1520  768 771 781 790 +hsync -vsync
