Yes: Three identical 1600x1200. I just have to find an available card that can handle three DVI connectors, ideally without having to buy an active adapter. (Sapphire makes a "Flex" card that claims to do this; my initial attempts to find one to buy have turned up nothing useful.) > TBH, I think it's a hw limitation on r5xx hardware that's not properly handled. I'd believe it as a hardware limitation if inverting the first two monitors didn't fix it. If I were willing to physically turn my first two monitors upside-down, it would work fine with the given hardware. The hardware can display across my three monitors at 4800x1200 as long as two of the screens are inverted. We just need to make the software put those screens into the hardware the other way up!
