Hi guys please i`m desperate for help.
I have a Samsung Syncmaster 959NF 19'' CRT monitor connected to an Radeon 5770 through an vga-dvi addaptor card on Win7 it only allowed me to select a refresh rate of between 75 and 85hz when i want to use 1280x1024 at 100hz i know the monitor is quite capable of this as this is the resolution i had it on years ago on a geforce 6600gt without any tweaks.

Anyway before finding this guide :
How to: Set whatever res I want to my monitor? (Disable Edid) - Overclock.net - Overclocking.net
and proceded to remove the 2 pins showed in the photo as initially i could read EDID data so after removing the 2 pins windows couldn`t recognize the monitors EDID but the stupid windows only showed 60hz max refresh rate after that.

Anyway after fiddling some more i found out that incase your EDID data doesn`t show i just pluged in an old Matrox pci card i had lying around and with the monitor cable still conected to the 5770 i was at last able to pick up the monitors EDID i tried to change with teh phoenix software to 100 Hz but not sure if i did it right the other program say i did but loading the driver the windows still only has 60hz max resolution.

Can someone please look at the dat file and tell me how to modify it to work?or is it a problem that i pulled 2 pins from the adaptor and it would now work?
Please help my eyes are killing me

Ok i finally think i fixed it myself i wrote the EDID file but since i broke off the 2 wrong pins on my original vga-dvi apater it didn`t seem to work i got a new adaptor used the modified moniotor inf i made before and enabled use EDID in ati drivers and it worked finally windows lets me select 100hz yey,if i disable edid in ati drivers the 100hz option disappears from windows

PS: I`m adding the modified inf file incase someone else needs it aparently the whole 100hz issue isn`t present in older ati drivers and hopefully will get fixed in the future so we don`t need epxloits.

Thank you very much for prividing this usefull information.Thank you

Ok well what i did is use the phoenix program to get the edid from the monitor at first it didn`t work not sure why but i added to the computer a old pci card left the cord into my 5770 and all of sudden the edid was viewable totaly weird afterwards it worked out that other card but with a new adaptor taht didn`t had any pins missin lolz .NOTE: My monitor has a vga connection connected through a vga-dvi apator so yes you don`t need a dvi conneter on the monitor

Anyway after getting the EDID i openeded it in the other program and just set the pxl clk to 180 in my case to get 100hz now saved the inf.then all you have to do is go to properties device manager go to monitor to go update driver go to have disk and show the location of the new inf and thats it it should say something like edid override in the device manager for the monitor.

Now all you have to do is enable edid in ati drivers and then go to monitor properties in windows and select 100hz and thats it,just disabling edid doesn`t allow you to use 100hz,you need the modified edid.Edid in catalyst 9.12 is somewhere in the monitor properties i think its a bit trichy to find i can look if you really want i`m on my laptop now which gives me an idea for those that can`t read the edid if you have a laptop connect your monitor to the laptop and see if can read it from there

Ok so to acces EDID in ati drivers go to desktops and displays you`ll see a pic of the monitor in the lower left corner right click on the triangle on the small monitor pic and chose configure and at monitor attributes you disable edid but that didn`t help me
