I have an ATI Mobility Radeon HD 4670 graphics card in a Dell XPS 1645 (8 GB RAM) running Windows 7 Pro. I have the laptop display extended across a Dell UltraSharp 2407FP at 1920x1200 and Wacom Cintiq drawing tablet at 1600x1200. I want to replace the UltraSharp 2407FP with a Dell U2713H at 2560x1440. I haven't been able to figure out, by visiting the AMD website, whether the HD 4670 will support that arrangement. Can anyone advise me?
I thought this would take just a second to look, but it took some digging. Also was a little curious because I have one laying on a shelf. AMD seems to have taken the specs off their website, but both Sapphire and Club3d websites show up to 2560x1600 max digital connection and 2048x1536 max analog connection.
