You can set your laptop to use
EnableDynamicScaling by opening regedit and changing the
EnableDynamicScaling from 0 to 1.
Bad news: Microsoft got sneaky and has now disabled that function in Windows 8.1. Once you set the scaling to 1 and change your resolution to 1024x768 and install Windows 8.1, you will no longer have the 1024x768 nor the
DynamicScaling for netbooks with a max resolution to 1024x600. Once you upgrade, you're stuck.
In regedit, go to Edit - Find, and enter
Display1_DownScalingSupported. On all occurrences, change value to 1. F3 finds the next occurrence. After reboot other resolutions should be available.
