GeForce GTS 250 weird driver problem strange screen display? - 2009/04/08 14:18 Hello there, after installing actual NVIDIA drivers I got some weird display scaling and/or positioning. There's a black bar about 30mm width on the right and about 10mm on bottom, picture doesn't seem to be positioned at all, and thus using DVI to HDMI cable. The monitor says it gets a 980P input signal albeit setting resolution to native 1920x1200, and even if I change driver settings in registry to not force native HDMI it gets a 480i feed.

Tested all new ForceWare drivers from the latest official to the latest beta, with and without flat panel ".inf" files, and even BIOS flashing to EVGA and low-level BIOS modding to force adapter scaling, with no succes. Without drivers all is fine, as soon as I install them screen goes crazy. Just so you all know I am using an XFX GeForce GTS 250 graphics card and LG L245WP display. Your suggestions are highly appreciated!

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.

Re:GeForce GTS 250 weird driver problem strange screen display? - 2009/04/09 08:08 Thanks for this mate, yeah I wanted to reply yesterday on it but really I was also puzzled and well due to some other urgent matters I didn't get any chance to react. But you have done some nice findings and it is great to see you have solved it. And by all means very strange it worked just fine with the GeForce 8800 series but not with your new GeForce GTS 250 graphics card.
