Maybe I interpreted my monitor specs wrong and mixed sync and refresh rates, here are accurate specs: Max Resolution : 1024 x 768 / 67 Hz Max Sync Rate (V x H) : 90 Hz x 54 kHz I would be very very thankful if you can provide me a modeline for these specs. ----- Original Message ----- From: "Mark Vojkovich" <mvojkovi@xxxxxxxxxxx> To: <xfree86@xxxxxxxxxxx> Sent: Sunday, October 10, 2004 12:04 AM Subject: Re: (no subject) > On Sat, 9 Oct 2004, Kamran Riaz wrote: > > > Thanks for your time, but please guide me on how can I add a custom > > modeline? > > To create one for a fixed frequency monitor is complicated. > You can consult ESR's howto at: > > http://en.tldp.org/HOWTO/XFree86-Video-Timings-HOWTO/ > > and other places on the net. > > Programs like gtf, which comes with XFree86 since version > 4.3.0, can produce modelines for multisync monitors.
