Windows 7 Screen Resolution maxed at 800 x 600

Post by ukcobra »

I have allocated 128MB of memory to the Display settings in VB, and enabled both 2D and 3D acceleration.

I am not able to select any further than 800 x 600 from the generic P n P monitor.

I have checked the manual, including the troubleshooting section and searched on here, and I cannot find any suitable threads to help me achieve a better resolution.

What should I be doing to improve the screen resolution.

Regards

The only option I get from the Windows Program list is to Uninstall it.

Should I be re-loading it from somewhere else ?

Found what was capping the resolution. It was not running in Max Screen mode, but in Windowed mode, so as soon as it filled the screen , it automatically changed the resolution to 1440 x 900.

Could n't work out how to switch back to the Mac Desktop so had to close down windows.

Full screen toggle = host+f
Seamless screen toggle = host+L
