problem refresh rate <-> resolution !!!

i have a big problem with my xserver and the vert refresh rate!!!

i'm using slack 8.1 upgraded to current 9.0rc1 -> but it doesnt matter if 8.1 or 9.0rc1!!

i configured my x server!

nvidia -> module for my 4400

twinview -> for dual screen

metamodes -> 1152x864@1152x1050,1400x1050

the 2nd display is a iiyama 22" 140khz mon

-> so i configured

SecondMonitorHorizSync 30-140
SeconfMonitorVertRefresh 50-200

when i startx i only get 75 Hz!! @ a res of 1400!!

when i use 1600 or 1280 -> x gives me 85 Hz

when i try redhat 8.0 (same x config!!) -> i get 85 @ 1400 res

so my question is -> how do i get 1400 @ 85 Hz

I think you will discover that many (at least most) here do not have this kind of equipment for dual monitor operation, etc. to be able to provide any real assistance.

Perhaps if you compare the XF86Conifg file from RedHat that works as desired against the Slack config file, you might locate a difference. As for me I know how to define color depth, resolution and general monitor spec. But how does X determine what vertical refresh rate to use, or how to change it I do not know. Well, I guess you could specifiy the refresh rate is limited to 80-100 and see if that would force it higher since I suppose you want the higher refresh in all modes.

You might check to see if has a mail list you could post the question. I think they do.

Perhaps it has been of a little help.
