How can I set interlaced resolutions on my two 980 Classifieds? On my second PC (PowerMac G5), I use SwitchResX to inject EDID overrides with the resolutions I want. Before I put in the two 980s, the system I am trying to get to interlace had a 7970. With the 7970, I used CRU (Custom Resolution Utility) to inject the EDID overrides. When I try to use CRU to inject the overrides, the resolutions show up but do not output a usable signal when selected. The image only shows up as a single line of pixels at the top of the screen. The resolutions I am trying to use are: 1280x960i@240Hz, 1600x1200i@192Hz, 1920x1440i@160Hz, and 2560x1920@120Hz.
