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. 

Moving back to New Zealand was a good time to get a new monitor. The cost of shipping my old monitor would have been more than it was worth, and I really needed a DVI capable monitor in order to test the DVI output. After looking around at what was available at what price, the final choice was the 22 inch Benq E2200HD. The E2200HD is one of the few monitors (right now) with 1080p HD as its native resolution (i.e., 1920x1080). This means that HD videos can be viewed at full resolution without stretching or extra black bands above and below the image. More importantly (for me), it has three inputs, DVI, HDMI, and VGA. This means that I can connect my Laptop and both graphics cards in the Amigaone (A1-XE) to the monitor without needing a KVM.

Today my Amigaone finally arrived in New Zealand. The hardware survived the long trek across the entire world and I am now in the process of updating my system via AmiUpdate. I forgot to buy a mouse and will be needing a DVI to HDMI adaptor in order to connect both graphics cards' DVI output to the new monitor (I'll post more about the monitor later). Once all this is done, I will finally be able to get back to developing the RadeonHD driver for Amiga OS 4.x.
