A DVI connection sends pixels straight to the display. Thank you, Galen. I believe there is DVI output. Is there anything in /proc or dmsg that will confirm that? I'll buy a DVI cable at ENU and reconnect the monitor. Late yesterday afternoon it came up with a new annoyance. When I log in I see a blank screen, apparently because the text that is normally displayed on the console is off the top. Feh!

Doing a quick search on DVI cables I discover that there are at least DVI-D Single link and dual link; DVI-A; and DVI-I Single Link and Dual Link cable types. The 6/8 bit stuff sounds bogus to me. There are specs for what is called single and dual link cables. A dual link cable is needed for high resolutions at high refresh rates(1,920 × 1,080 @ 85 Hz, for example) or for high pixel depths(24 bpp). In most instances dual link is not needed, but I suspect that you would find that most cables are DVI-D dual link anyway. My best guess as to your sharpness issue is either a poor quality cable or the LCD not being driven at its native resolution. -- Galen Seitz gal...@seitzassoc.com ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Rich, No problem if you don't make it. You can either contact me or wait for the next meeting (held every 2 weeks) to take a look at the monitor. If you can give me the model number of the monitor and/or the voltage and current rating of the power supply, I'll see if I have one for testing as I am betting that is where the problem lies.
