Re: [XFree86] Odd Screen Overlap - Fixed
I have not being following the thread since Mark is on it. But, if I understand your question. Can your monitor keep working on 75Hz instead of 60Hz. The answer is YES. As long as it is in the specified range that should be okay. Carl F. Hall wrote: Thanks for the suggestions Mark. I changed the vert sync range and horiz. range to the those you said were in the log file for the monitor's EDID. After doing so, I still had the problem but now have available 75Hz along w/ 60Hz. I didn't think my monitor worked at anything by 60 but whatever. So I selected 75Hz and the overlap went away! If this will detremental to my monitor, someone please let me know. Otherwise, I'm going to keep on going with it.

It also specifies a vertical sync range of 56-76 Hz and horizontal range of 30-80 kHz (you have 50-75 and 30-65 in your XF86Config). XFree86 chose a [EMAIL PROTECTED] (64KHz) VESA mode with an identical refresh rate to the prefered mode in the EDID. In short, the mode XFree86 chose should have worked, and it sounds like it did at one time, so I guess we can't rule out a hardware issue. You can try changing the sync pulses. It's using the following modeline now: Modeline 1280x1024 108.00 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync If you put that line in the Section Monitor XFree86 will use it instead of the internal one. You can change the pulses by changing the +/- before the hsync and/or vsync. You also might want to check your monitor cable to make sure it's plugged in tightly. If this doesn't work you could try lowering that pixel clock (the 108.00) a bit to see if it works any better (eg. something between 102 and 108). Does your video card have a DVI connector?

Re: [XFree86] Odd Screen Overlap
Thanks for the responses on this. It's made for an interesting day at work having to read around the overlap. I've tried rebooting the machine as well as a complete shutdown and still get the same thing. When I try different resolutions (1024x768, 1280x962, etc) the overlaop goes away. Should I check into setting the vertical sync rate and , if so, how do I know what is the right one for my monitor? Mark Vojkovich wrote: On Mon, 14 Feb 2005, Carl F.

Re: [XFree86] Odd Screen Overlap
The monitor's EDID (printed out in the logfile) indicates a prefered mode, which implies the native panel resolution is 1280x1024.
