LCD display "signal out of range" SOLUTION

LCD display "signal out of range" solution Linux: Linux system prompts "input signal out of range", except for the reason of refreshing frequency, the configuration of the desktop system is also very important. Solution: restart the computer and wait for a while. After the system is started, the system prompts "the input signal is out of range" and press alt + ctrl + F1 to enter the Linux Command Line Mode, enter the system as a root user (or Log On As a normal user before using the su command ). Go to the desktop system configuration directory and run the gtf command: cd/etc/X11 gtf 1024 768 1024 85. 768 and are the resolutions you want to set, and 85 are the refresh frequencies you want to set. After you press enter, the system will output the following information: #1024x768 @ 85.00Hz (GTF) hsync: 68.60 kHz; pclk: 94.39 MHz Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772-HSync + Vsync backup xorg. conf file, and then open it in the vi editor. cp xorg. conf xorg. conf. aaa vi xorg. conf finds the code of Section "Monitor" in the file, copy and paste the entire line of Modeline code in the text output by the system after using the gtf command above to the Section "Monitor" code. As follows: section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "LCD Panel 1280x1024" HorizSync 31.5-67.0 VertRefresh 50.0-75.0 Option "dpms" Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772-HSync + Vsync EndSection change the VertRefresh line value to 50-807 (recommended for LCD display to 60-60 ), save the modification and exit. restart the system. Summary: LCD displays that "the input signal is out of range" are generally caused by high refresh frequency. In addition, the refresh frequency of the LCD is generally between 60 and 75. When configuring the LCD, it is best to refer to the recommended configuration in the monitor manual for better settings. [Size = xx-large] The desktop cannot be displayed after the ativideo card driver is installed beyond the specified range [/size]. In linux, see: the video card driver downloaded on the nv official website, right! The same as I used! First, add executable permissions to attributes. Second, put it in the "/" folder (this makes it easier .) Third, change the name to a very short name. For example, nv. run (this makes it easier .) Then ctrl + alt + f1 and then sudo stop TPD and then sudo sh/nv. run are done after sudo start TPD and above is my practice in Ubuntu 9.10. So I plan to install ati's official driver myself, I downloaded the ati-driver-installer-10-11-x86.x86_64.run installation can not log on to the desktop, the previous modification xorg. the conf method does not work either. It does not work if the video card driver is re-installed several times... I 've been tossing for a long time .... want to uninstall the driver, Baidu to: sudo/usr/share/ati/fglrx-uninstall.sh seems that this uninstall almost does not need time, after entering the command becomes, and then restart... come in... an effective shot .... --------------- linux really seems to be suspended... it is easy to log on to the desktop... the solution is amazing... currently, general-purpose drivers are used --!... Done... it's really easy .... --------------------------------- I uninstalled all the fglrx items in the New Delhi, uninstalled ati, and re-installed atixxx. run to open ccc directly or prompt for previous problems... restart, still out of range ------------------------------- aticonfig -- initialaticonfig -- resolution = 800x900,1280 x (the problem is here ....) stop TPD; start tPD is still out of range --------------------------------- I tried aticonfig -- resolution = 800 x stop TPD again; when the start TPD comes in, open CCC immediately. this time I can use it... I suddenly realized the resolution option. My display resolution is 1440x900. I used to write 1400x900.
