Monitor problem
 
alright here is my issue. I have had fedora core 3 installed before with a different video card and it seemed to work fine with my plug and play NEC FE991SB minitor. But know with a newer card, which seems to somehow disrupt the plug and play from working I couldn't set my refresh rate above 60 Hz (hard on the eyes) with the generic driver. So currently I'm using the built in driver for a View Sonic A70f+ which seems to work and lets be select the 75 Hz refresh rathe that I was after. My only worry is I've read that with the rong sttings X will fry your monitor. Is this True? and also is there any driver for this model out there? or is tehre any way to use an windows .inf driver in linux?... all help is appresiated thanks

On almost all modern monitors if it will display on the screen, then it shouldn't hurt the monitor no matter what settings your running it at. Some older monitors though cant handle it and supplying the wrong settings can potentially screw things up, for example, I had an old packard bell monitor that I toasted because I ran it at too high a resolution and refresh rate and it started overheating, the tube would get VERY hot on that high resolution, and finally I decided to strap a ran up ontop of it to cool it off... one day the fan died and the monitor over heated sevely and before the automated shutoff safety thing kicked in it screwed something up, and now I can only run it for maybe 10 minutes on any resolution except 640x480 before it starts shutting off sparatically. Keep in mind though, this monitor was quite old... if I remember correctly, manufactured around 1993 or 1994. Like I said, most modern monitors can handle what you give them... if you supply an unsupported setting, they just wont display anything and the monitor automatically shuts off, old ones though, if you supply the wrong settings, they will get all weird and stuff starts scrolling all over the screen and zigzagging every which away... not good. Most of the times that wont imidiatly DAMAGE the monitor, but I cant say that its good for it either.

The most important settings in X that are related to the monitor are the HorizSync and the VertRefresh.
For your monitor they should be (according to http://www.dealtime.com/xPF-NEC_Mult...9_in_20246655)
Code:

HorizSync  30 - 96
VertRefresh 50 - 160

You can manually modify them in the X configuration file in /etc/X11; you need root privileges for it.

Most modern monitors will give an 'out of range' message (or something similar) when you give them something that they don't like.

PS A monitor does not have drivers (not in Linux and not in Windows); it's just a config file that tells the system (amongst a few other things) which refresh can be used.
