I have a SUN GDM-1955A fixed frequency monitor and can only get my xserver to work with 640 x 480 at 32bpp. I don't know the actual refresh and scan rates of the monitor and am looking for some help. Anyone got one of these working on X? I don't think any of this will matter but here is sys info. AMD K6-2 500 RH 6.1 10G HD (4.5 Win98, 5.5 Linux) 64M RAM CDRW, & DVD TIA, Frank

Sun sold at least 6 different models of the GDM-1955a. They were all
1152 x 864 composite sync monitors with hsync of 61.8 kHz and vsync of
66 Hz. They were 19" monitors with 4 BNC connectors (but you knew
that), and the primary difference between them was the tube model.
Sony made all of the tubes (and changed the tube model when the spirit
moved them). More info at:
http://www.monitorworld.com/monitors_home.html
Getting fixed frequency monitors to work can be a chore (3 down, 2 more
to go), especially if you do not have a video card that was designed to
work with fixed frequency monitors. Here are some faqs about this:

Good luck!!

Actually my monitor has a 13W3 connector but I already have it working with 640 x 480. Just wanted to know if anyone had more specs on how to set it up for 1200 x 1024 or 800 x 600. Thanks for the links though.

The esential specs you need are that the monitor runs at a hsync of 61.8 kHz and vsync of 66 Hz. A result of this spec is that you will get about 1152 x 864 on the screen. Actually with enough ram in your video card you should be able to get 1200x1024 . At 32bpp you would need over 4 meg of video ram. You should be able to run at 16 or 24 bpp with a 4 meg video card. But you can always display black space if you are short of ram. you must always run at 66khz, 66hz.. so you must be looking at 640x480 the picture must only be in part of the screen. given a XF86Config like this that works ... Modeline "640x400" 25.175 640 664 760 800 400 409 411 450 CLK A B C HS D E F VS If you add 560 to A , and 624 to D , you would get 1200x1024 Maybe add some to B and E , as long as C and F stay clear of HS and VS. then adjust the size to keep the display on screen (after adjustment of the monitor) without using up all available video ram (if you are limited there). CLK HS and VS determine the horizontal and vertical sync rates. (and set a maximum on the number of pixels and lines ..) Actually xvidtune can bump these settings up for you. leon > James Hunter Heinlen wrote: >> On Thu, 06 Apr 2000 23:21:40 -0400, patrum (patrum@erols.com) suffered dangerous fits of clarity and wrote: >> >> > I have a SUN GDM-1955A fixed frequency monitor and can only get my >> > xserver to work with 640 x 480 at 32bpp. I don't know the actual >> > refresh and scan rates of the monitor and am looking for some help. >> >> Sun sold at least 6 different models of the GDM-1955a.
