- AMD Radeon HD 7870 2GB DDR5 (purchased from Dell already installed in new XPS 8500 with 16GB DDR3 SDRAM @ 1600 MHz) w/ 3rd Gen Intel Core i7-3770 processor
- 2 Dell ST2420L monitors: one connected via HDMI, other connected via DVI
AMD Catalyst Driver Version, and Driver History
- Windows 7 64-bit
- I want to use the 2 monitors as an extended desktop (that part is working fine), but I naively expected to be able to configure both of them to perform the same at their maximum potential. The monitor connected via DVI is set as the “main desktop” and configured to run at 1920 X 1080 @ 60 Hz – the recommended setting for the monitor and the maximum resolution described by Dell. The monitor connected via HDMI is currently configured at 1080p @ 60 Hz (under HDTV section of “Desktop area:&rdquo and the list of “Basic” settings does not include an option nearly as high as 1920 X 1080. In fact, the list only goes as high as “1680 X 1050”.
How can I, if it’s possible, get Catalyst to let me configure them both at the same optimum resolution? I understood that DVI and HDMI are equivalent in resolution. I’m sure I’m missing something obvious, but I’ve tried to find any help in the Catalyst Help files, and I don’t see how to do it.
I’m not using this set up for games or HDTV, just desktop applications and web browsing with some video surfing. However, it seems to me that I should be able to configure two identical monitors in the same recommended way.
Can someone please explain how to go about doing so? Thanks for any help.
