Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.69e Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi. I'm noticing a strange thing happening on my computer. At higher refresh rates (above 72Hz), I see what I can only describe as "shadows". For example, the borders of windows seem to have a little grey fading border on the right side. If the mouse is over a simple green background, I can really see the "shadow". It's quite annoying - even the black letters on the white background of my rxvt leave a little grey silhouette to the right. I'm guessing it happens (or more likely is visible) whenver you have sharp contrasting colors next to each other. Has anyone ever seen anything like this before? I'm not sure if it's the video card or the monitor. I'm going to bring another monitor home from school some day to see if it behaves similarly (which would mean it's the video card). I suspect it's the monitor though; The problem seems to get worse as I approach the maximum refresh rate of the monitor (which is why my hunch leans towards a monitor problem). I'm hoping this is some sort of gun alignment problem or something.. Specifics: Matrox Millenium (original, 175MHz RAMDAC) with 2MB WRAM. MAG Innovision MX17F G (the one with the LCD thing on the front). Same behaviour under FreeBSD (with AccelX), Windows95, WindowsNT. If anyone has any clues, I'd LOVE to know what you think!! -Mark -- ---------------------------------------------------------------------------- Mark Mayo mark@quickweb.com RingZero Comp. http://vinyl.quickweb.com/mark finger mark@quickweb.com for my PGP key and GCS code ---------------------------------------------------------------------------- University degrees are a bit like adultery: you may not want to get involved with that sort of thing, but you don't want to be thought incapable. -Sir Peter Imbert
