Re:GeForce GTS 250 weird driver problem strange screen display? - 2009/04/09 02:22
Okay a small update, problem solved. For people encountering similar problems, I had to override EDID flags in registry to force proper display resolution, seems to be some driver incompatibility. I've chosen to update "nv_disp.inf" file in extracted ForceWare driver before installation.
You will need to add a tag, and depending on the driver version that you have and then you will need to add some key, where the first four digits are monitor specific and which can be read using the Phoenix EDID designer. In my particular case the display digits are 1E 6D 24 56, and this might be different for everyone depending on the monitor you have.
Adding Registry Tag, Driver Depending...
- [nv_commonDisplayModes_addreg__02] or
- [nv_SoftwareDeviceSettings]
Updating Registry Entry, EDID Override...
HKR,,OverrideEdidFlags0,%REG_BINARY%,1E,6D,24,56,00,00,FF,FF,04,00,00,00,
7E,01,00
Strange, but on my GeForce 8800 there were no issues regarding this at all, using the same monitor. So really somehow unlogic that this is happening with the GeForce GTS 250, but well it did happen so just in case I am sharing my solution with all of you.
