I have an Apple G4 15" (Widescreen). I also have a Dell E173FP LCD Monitor that I bought thru my work when Dell was selling them for like $170 with desktops. Anyways, I have to use the DVI -> VGA Adapter that was included with my PowerBook G4. When I first plug it up it seems to be fine. After it being on for about 30 to 40 minutes the text starts, for a lack of better words, "jumpy". It literally seems to jump left to right about 3 pixels. Its not just the text, if you look closely its eveything.
When plugged into my PC I have no problems using the monitor.
I dont have DVI on the LCD Monitor so connecting straight to DVI is not an option. I am running the monitor at Dell's recommended resolution of 1280 x 1024. I have tried different resolutions and refresh rates trying to find a good way to avoid it but cannot. I also dont see a way to upgrade the software for my video adapter thru Apple.
