CountGFXModes() Trouble

Blitz3D Forums/Blitz3D Programming/CountGFXModes() Trouble

I'm having a bit of a problem with resolutions. I'm using code to determine which resolutions my graphics card can display which is all well and good. These commands I'm sure should also filter out any resolutions that my graphics card can support but my monitor can't display, hence it doesn't list 1600x1200 even though I have a GeForce 7950GT. It does however report that I can set the resolution of 1280x960, if I set this the program continues to work though my monitor cannot display this resolution. Has anybody else encountered this and what method would you recommend in dealing with it?
