Sun 100U video display Issues

Yes I can confirm it is a issue with the video input at the wrong resolution and frequency. The bwtwo card is 1600x1280 and my monitor is made for 1024 lines of resolution. Hence, I need to use a different video card (the bwone). Thanks everyone for the help! -------------------------- On Aug 7, 2012, at 12:20 PM, Nick Allen wrote: />/ />/ On 8/7/2012 10:57 AM, Nick Allen wrote: />>/ Hey everyone, I ma repairing a Sun 100U computer, and am having some issues I would love some help with. I am using a bwtwo video card with the Sun 100U CRT (its a 17" HD B&W phillips CRT). I am getting an image showing a successful boot, but I am getting a split double image (like split screen but the same image on both sides). Any ideas what is causing this, a frequency issue? Any jumpers/settings on the video card which may inadvertently cause this? Could it be a CRT issue? />/ / Horiz frequency issue. i was working for a place a while back that de-tuned sun monitors for macintoshes and for a specific fixed freq video card. for the life of me I don't remember how to reset the freq of the video card or if the bwtwo was capable of supporting different frequencies.
