I have just set up my Power Mac G5 Quad with 3x 2560x1440 displays, they are set up horizontally, I have 3x graphics cards running the 3 displays, the 2 side displays are set up using PBP using 2 inputs on each (4 DVI in total), the centre display is set up as a standard display using DVI but looks fuzzy at 60Hz using the full 2560x1440 resolution. Is there an app like RDM (Retina Display Menu) for PPC? Or a workaround that you know of? It was working at 30Hz and not blurry before I plugged in the 2 side displays... Now there is no option for 30Hz only 60Hz. My config is OSX 10.5 (Fully updated) NVIDIA GeForce 6600 1. Driving left display using PDB with 2 xDVI 2. Driving centre display with 1x DVI 3. Driving right display using PDB with 2x DVI I am using correct cables.
