[Problem]
A Logix LG-1731D monitor has incorrect EDID, causing an incorrect dpi calculating resulting in fonts that are too large.

[Original Report]
A Logix LG-1731D monitor capable of 1280x960 starts up in 1400x1050 mode. The GUI is unusable due to enormous panel fonts (see attached picture).

The attached Xorg.0.log warns of a changed PIPEASTAT register and a failure to allocate texture space.

This monitor works fine with an old nVidia card and the nv driver.

Cheers.
