I'd say the monitor doesn't provide any EDID data (or the transfer or data is broken) - check /var/log/Xorg.0.log on this!)

a) Don't try to drive it on 1000x800 - the outcome will always be blurry. Set it to 1280x1024
b) if you can, use the DVI connection. It will not only provide you a better image, but likely also bypass this problem.

Other than that you need to either
a) obtain the EDID data from the monitor (there're tools to dump it, but you'll most likely get no data or broken data as well)
b) write/calculate a modeline and add that (for this monitor) to /etc/X11/xorg.conf[.d/some_snippet.conf]

For the latter eg. fill this form with the data from the monitors tech sheet:

PS: really try using DVI ;-)
