I've got a good one : how do you find these refresh rates if the documentation doesn't mention them ? ---------- From: f.kater@gmx.net [SMTP:f.kater@gmx.net] Sent: 30 October 2002 10:09 To: newbie@XFree86.Org Subject: Re: degrade refresh rate for LCD Yongming Wei: > Hi all, > > I changed my monitor from CRT to LCD, then I install > redhat 8.0, X could start without any problems, and it > looks good. > > However I have concern that the manual of LCD > recommend refresh rate set to 60HZ at 1024*768, but my > X default looks for the highest refresh rate which is > 75HZ(hope that would not damage my monitor). > > I looked for some documents only found how to set > modeline to change the refresh rate, can somebody give > me suggestion of how to set my refresh rate to 60HZ? > Hi, I have got a LCD, too, and I experienced very good results when I entered the *exact* refresh rate(s) supported by the LCD display.
