ATI Mobility Radeon HD 4650
Windows 7 64 bit
Driver Version 8.970.100.1100
External Monitor: DELL ST2420L connected via VGA cable
Machine is a Dell Studio 17 (Model 1747).
The previous driver version (V?) worked fine but now when I display only on the external monitor, the image is compressed horizontally (black bars at right and left edges). When I "Extend" the display, it works normally, i.e. the entire screen is used. I need to use this version since the previous version had an out-of-date Open GL version.
