Re: [XFree86] Unable to set vertical refresh rate correctly
Try a gtf-based modeline generator like gtf in the XFree86 4.3 prerelease snapshots. Trying that, I get: # 1152x864 @ 100.00 Hz (GTF) hsync: 91.50 kHz; pclk: 143.47 MHz Modeline 1152x864_100.00 143.47 1152 1232 1360 1568 864 865 868 915 -HSync +Vsync Mark.

Re: [XFree86] Unable to set vertical refresh rate correctly
I still havn't found any way to set my fresh rate to 100hz. I've been searching for documentation on the subject for a while now, and thus far nothing has helped. The only configuration document that I have found (besides random ramblings on google) is the Debian XF86Config-4 man page. It's helpful for various things, but not for my specific problem. Also, there doesn't appear to be any official config file documentation for 4.2.1. Again, my vid card is a geforce2mx, nvidia driver, on an Elements 9D monitor. Does anyone know how to force X to set a certain fresh rate? Thanks, Eric Mangold ___ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86

Does anyone know how to force X to set a certain fresh rate? There are several ways to force a vertical refresh rate. First, if you are only running one resolution, specify: VertRefresh 95-100 In your monitor section in your config file to specify a vertical refresh of between 95 and 100HZ. This should be sufficient by itself. You can also specify modelines with the correct pixel clock. You would need to google for one of the mode line generators and use it to generate a modeline for your monitor with the correct horizontal, vertical and pixel clocks. Frankly, setting a refresh rate of 100 is useless. I have extremely sensitive eyes and I can not notice a refresh above 82Hz or so. Second, a high refresh rate reduces the clarity of the image on your screen. Problems such as ghosting appear. Poor quality cables, long cables, high resolution or a low quality monitor make the problem worse. Your refresh rate should be a few Hz higher than the highest refresh rate at which you stop noticing flicker. If you can still see a flicker at 75Hz then run your monitor at 80 or 85. My ViewSonic P815 was capable of 120Hz at 1600x1200 (I believe. Been a long time since I used a CRT). I never ran it above 85Hz because it simply wasn't necessary. If you want a 100% rock solid image, then get an LCD. -Don ___ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86

I have good eye-sight and there is a noticeable difference between 85hz and 100. My monitor isn't that great though, so perhaps it would be less noticeable with a higher-quality display.
