Debian Linux X-Server fine-tuning resolution

You can use a few simple commands to make X work better. In many cases, the X environment installed by default is not what we expect. For example, I recently installed the initial setting of Ubuntu to automatically set the display resolution to the limit of @ 60. We can use the following method to calculate the appropriate value of the display resolution to tell xorg. conf to make the display work more appropriate.

1.You can use the gtf command to calculate the relevant value of the display resolution (for example, 1024 × 768 @ 100)

Gtf 1024 768 100

Calculate the correlation value of 1024 × 768 100 HZ. The output is as follows:

#1024 × 768 @ 100.00Hz (GTF)Hsync: 81.40 kHz;Pclk: 113.31 MHz Modeline "1024 × 768 _ 100.00" 113.31 1024 1096 1208 1392 768 769 772-HSync + Vsync

Add the line Modeline above to the monitor field in the X configuration file.

2.Directly modify the line frequency and field frequency in the XFree86Config/Xorg. con file.

UseXvidtuneCommand to start a GUI fine-tuning window, provided that you have correctly installed the graphics card driver.

We can use VI to edit the configuration file of X. modify the configuration file directly in the following field:

HorizSync 30.0-85.0 VertRefresh 50.0-160.0

The above is the official value of my diamond monitor. I obtained it from my own website. It is recommended that you strictly refer to the instruction manual when modifying the settings. Do not cry when setting too high to burn the monitor.

Supplement:

Field Frequency: The field frequency is also called "Vertical Scan Frequency" or "refreshing rate ".
The number of times the electron gun scans the entire Screen in seconds, usually in Hz.
Taking the refreshing rate of 85Hz as an example, it indicates that the display content is refreshed 85 times per second.

Line frequency: the number of horizontal lines scanned per second by the electron gun on the screen.
The value is equal to "Field Frequency × vertical resolution × 1. 04", in the unit of KHz ).
The line frequency is a parameter for comprehensive resolution and field frequency. The larger the value, the higher the resolution that the monitor can provide, the better the stability.
