no, i used the radio buttons options. I'll look into that, thanks.Are you using the default Slider or the Older Windows 8 (and earlier) setting for DPI? Using the slider you should get 150% on the Surface and 100% on the external monitor, you can adjust the settings of any Win32 program if they don't look crisp by right clicking the ".exe" or short-cut and clicking properties, Compatibility Tab and checking the box Disable display scaling or High DPI settings.
