I've read that the look of fonts depends on how display size and resolution is set for X. Yup. Currently my xorg.conf setup is this: Section "Monitor"   Option       "CalcAlgorithm" "XServerPool"   DisplaySize  310 230 xdpyinfo|grep dimens   dimensions:    1024x768 pixels (313x232 millimeters) xdpyinfo|grep resol   resolution:    83x84 dots per inch

I am confused why the dimensions are different in the xorg.conf file and given by xdpynifo. Often the configuration utility cannot determine the exact DisplaySize... so its approximate... like 310x230. This measurement is the actual viewing size in mm. (You can measure it with a millimeter ruler if you like). The dots per inch is a conversion on the physical resolution of the monitor. Doing the math on your pixels vs dots per inch you have a 15" monitor. Probably the 313x232 is correct... and you just need to specify that setting in xorg.conf. But I would measure the actual display area with a mm scale first. Of course you can use SaX to set the value or you can edit xorg.conf yourself with vi.

I'd like to suggest that if nice fonts matter to you, that you at least test, if not switch to permanently, either:

1-choose a display resolution that calculates as close as possible to exactly 96 DPI for your display (only if your display is not a flat panel, otherwise stick to the flat panel's native resolution), or

2-choose the highest display resolution your display supports for your choice of color depth. This is not always the same as the highest resolution your monitor's specs claim.

Thanks for the answers. I read the NVIDIA driver's README file and it said that the values specified in xorg.conf file are overridden by the values supplied by EDID/DDC. So one have to use the option Option "UseEDIDDpi" "FALSE" for making xorg.conf's own DPI setting into effect. Really, after diasabling UseEDIDDpi xpdyinfo reported the correct dimensions. Now turning back to your advice, changing the resolution to higher: I would like to keep 1024x768 @ 85Hz (LG Flatron 17" CRT monitor, 16" diagonal viewable). Setting dimensions to the real monitor values (325x244 mm) gives ~80 DPI. What if I raise DPI by applying false dimensions, eg 271x203 mm (what should give ~96 DPI)? Or setting dimensions to 345x260 mm what should give ~75 DPI? Which one would be better and how does it affect resolution for other stuff than fonts?

Any particular reason why you prefer this common low resolution to high quality? (high resolution = high quality, so the higher the resolution, the better quality of detail, just like in a high resolution satellite photo or high resolution scanner)

CRT monitor, 16" diagonal viewable). Setting dimensions to the real monitor values (325x244 mm) gives ~80 DPI.

Fonts and system windows will be bigger. You'll be seeing things much like a typical windoz user sees things, as 96 is the default on doz, and your display size is pretty common.

Or setting dimensions to 345x260 mm what should give ~75 DPI?

Fonts and system windows will be smaller, and fonts generally less well defined on account of being created using fewer px per any given physical size character.

Which one would be better and how does it affect resolution for other stuff than fonts?

Since 1024x768 is the maximum resolution @85 Hz. All higher resolutions are @<85 Hz on my monitor.

Can you actually tell the difference between 85 and 75 or 80? Even if you can, I still suggest you test as I originally suggested, to see with your own eyes what high resolution can do for fonts. It seems to me that running a display at its maximum refresh would be like running a car full throttle all the time, which accelerates wear and shortens life. I run all mine at 60. Not everybody's eyes can see or are bothered by screen flicker. -- "I have come that they may have life, and have it to the full." John 10:10 NIV Team OS/2 ** Reg.

Are you talikng about CRT display? I feel you are using LCD displays....

My only LCD is less than 5 months old. I have 10 CRTs. I have run them all at 60 ever since last century, except if running windoz with a video driver that won't let me specify the refresh I wish. -- "I have come that they may have life, and have it to the full."
