Talking Xorg issues with Nvidia GTS250 and Slackware (Some items too large, others too small)

I'm having some problems with my Sanyo DP42849 (42inch 1080p) TV and Slackware. I believe it to be Xorg related, but I'm not 100% sure. Firefox is ungodly huge (as are most programs) but KDE looks just fine after configuring font size. I noticed under system settings that it shows resolution as 1920x1080@50, which is correct except for the refresh rate (should be 60). I was told by a friend that it was a modeline issue, and so I setup my own modeline but it seems to be ignoring any changes I make to xorg.conf.

Copy of xorg.conf:

        Depth       24
	modes       "1920x1080@60"
Most of that was auto generated by the Nvidia installer, some of it was added later. I'm not too familiar with hand editing the xorg file, and using the configure utility with Slackware doesn't give me the option to use my Nvidia driver so I haven't used it.

Any help would be appreciated.

from what I understand, your problem is font-related? Too big fonts? This should prove as a guideline where to begin. In KDE you just set the DPI in the font configuration dialog, and you're all set. (no idea how this setting applies on GTK applications.)
As for the refresh rate, with the official driver the reported frequency has always been off, the same as you, it never was an issue. What is important is what your screen reports receiving.

Thank you for your response. It was indeed the DPI settings, it was set at 305x305. I manually set it to 96x96 (the "DisplaySize" setting had no effect, even with correct values).
