Well hey, whadda ya know? A Dell 2405FPW ...

"Why didn't you say so before?" I'm running my 1920x1200 on a Dell 2407WFP - nothing like a CRT there, a TFT very similar to yours.

I've got my monitor file Prefs/Presets/Monitors/Dell 2407WFP (which I think contains hfreq, vfreq, hsync & vsync as well as the screen modes), find it at Dell 2407WFP.

The usual disclaimers for this file of course regarding explosions, psychotic behaviour & treatment, axe damage and so on, but if your TFT does 1920x1200x24 @ 60Hz, you might want to check if this doesn't exceed your monitor's specs and adjust them as needed, but I'm guessing this is all you need. Let me know if this works for you.

Oh, and a bit of food for thought: This monitor file started out as an Iiyama MT-8221E monitor file, for a 21" CRT.
