I am pleased to announce that the RadeonHD driver for AmigaOS 4.x can now also output to DVI on Radeon HD 4000 series cards. Apart from being another item ticked off the driver development to-do list, from a personal perspective this means that I can now use my 4-port DVI KVM switch fully. Previously, switching to my Sam460ex would mean the monitor switching to the VGA output, and then manually switching to DVI again when switching back to another machine. The button on my monitor for switching inputs has already lost its "click" sensation due to the large amount of switching, so I am glad to hand that task over to the KVM.

Days after having my Amigaone back up and running the RadeonHD driver can now drive monitors via DVI.  Last night, a 1920x1080 @ 60 Hz screen was successfully opened by the driver (see the photo below).  This test was performed with an HIS Radeon X1550 PCI card (RV505 chipset). DVI, or Digital Visual Interface, is a monitor interfacing standard that uses digital signalling in order to achieve maximum quality. The older VGA standard used analog signals, which could degrade with long/poor cabling.
