I've just installed my copy of Windows 7 RC and I can't seem to change the resolution to a widescreen (16:10) one. I'm using an ATI Radeon X1650 Pro PCI-E which the standard driver from Beta worked in allowing me to change to a widescreen resolution. Now it doesn't want to give me the option for widescreen resolutions. Any ideas? I've already tried a few of the ATI Catalyst downloads but those won't give me the choices for widescreen resolutions.
