Title: New Drivers wont allow above 60Hz at res >or= 1280x1024
Post by: Jimbafette on September 17, 2008, 04:17:50 AM
All the recent geforce drivers for my 9800gtx oc, wont let me set my refresh rate above 60Hz@1280x1024. I had a 7800gt before and that was fine it displayed all my desired refresh rates. I Have the same monitor with the 9800gtx as i did with the 7800gt. I have emailed nvidia, their response to my questions was :-
"The reason the new drivers do not allow the refresh rates you are speaking of, is because all our recent drivers are EDID compliant. Your monitors EDID must not allow for these refresh rates. "
"Please contact ur monitors manafacterer for updated EDID. "

I contacted asus as i have an Asus PG191 19" LCD 2ms, they told me there is nothing wrong with the EDID on my monitor. Asus told me that the graphics drivers must be interpreting the EDID incorectly.

Well i'm not sure who is at fault but i would just like to get back my 1280x1024@70,72 and 75Hz. I found a Ultimate Monitor Inf here at http://www.videoi.com/~pietro/monitor/

I'm just not sure that this will be right for my monitor could someone who knows about this sort of thing please check it out. My friend has tried it, works for him so far ! would like to know if this could be changed to suit my monitor ? I'm currently using 177.79 geforce drivers!

Now even this inf gets replaced when i reboot ?

Please Help !

You have an LCD and that file is for a multisync CRT. Lots of LCDs only run at 60Hz, but download and run MonInfo on your monitor and then post the results. It grabs and decodes the EDID.

But that ultimate monitor inf worked till i had to update the drivers, is there anyway to modify this to suit my monitor.   As my monitor definitely is capable of my native resolution at 60,70,72 and 75 Hz respectively.  I have not played a game or had my desktop set to anything lower than 70Hz for the last 3 years and i really don't want to have to settle for less.

i am now looking at altering the nv4_disp.inf file to add those refresh rates at my native resolution of 1280x1024.  But i still don't understand the code well enough yet to feel confident to edit it just yet.  I want it to be done right !
By the way thanks for your measured response its the best response i have gotten, as i have post my issue on at least 6 graphics related forums.

SO THANKS IN ADVANCED   :)

You didn't post the MonInfo report from your LCD, so I can't coment further. As Nvidia already told you, they are no longer using monitor inf files if their is an EDID, where before they were, so it doesn't matter what you use for a monitor inf file now - it isn't used.  

Also editing the nvidia driver inf file won't help here because it only sets what the graphics card can do, not what it will allow you to select - that is determined by the monitor. I.e., NVidia drivers have always supported 240Hz - a refresh rate that would literally destroy most older CRTs - so they don't allow the user to select 240Hz unless the monitor explicitly supports it in its EDID.

Post the MonInfo report.

Here is the Monitor.mif at the bottom, could you please explain to me why i have been able to use these refresh rates 70,72 and 75Hz at 1280x1024 for the last 3 years with no problems !
So its just these new drivers that wont allow me to use the ultimate monitor inf then ??  

Is there any way to alter the montitors EDID to support those refresh rates, as my monitor is definately capable of them.  

Or will i be forced to use the older drivers to get the ultimate monitor inf working again?
 My friend has the exact same setup as me as i built it for him, the ultimate monitor inf works for him fine with the Geforce v175.16 drivers.

It was then that i treid using it with the new Drivers but it just reverts back after reboot.

Was wondering if the the install order could have something to do with it ?
   
On my friends machine the install order was Windows Xp SP2>nforce chipset drivers >Directx Latest v9.24 > Windows updates including Win installer 3.1 > Geforce 175.16 > ultimate Monitor inf.

Where as my install order was the same except i did not install Directx as 9.0c is includded with service pack 2.
This would'nt have affected things could it ?

So if i just find a way to either alter the monitors EDID i should be able to get those refresh rate back at my native resolution of 1280x1024.

Could powerstrip do that for me ?

I though NVidia already answered that question for you???

The newest NVidia drivers - and this is a Microsoft Vista requirement too - respect the EDID.

There may be, but its not something the average user should be doing.

That is your easiest course of action, but are you sure this isn't much ado about nothing? Check 1024x768 at 75Hz and at 60Hz - do you see any difference whasoever on your LCD?
