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.

Don wrote: First, if you are only running one resolution, specify: VertRefresh 95-100 Good idea, I'll give it a try. 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.

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. 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.

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.

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.

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

[XFree86] Unable to set vertical refresh rate correctly
Hi, I'm trying to setup Xfree86 4.2.1 for use with my Elements 9D monitor and a GeForce2MX 200 graphics card. It is currently working fine with the nvidia driver. The problem is that X is setting my monitor to 75Hz at 1152x864. The monitor is capable of 100Hz at that resolution, and that's what I'm running at under Windows. I've tried running "X -configure" but that doesn't do anything special with regard to my monitor. I've also played with xvidtune, secifically adjusting the width and height in order to raise the refresh rate a bit. I havn't been able to make it operate above ~84Hz while still being able to compensate with the physical monitor controls. In other words, anything higher and I can no longer keep the picture at the right physical dimensions.
