Windows 8.1 probs

First of all, I'd like to say that I'm enjoying the update for the most part but I'm having some very annoying problems.

1.Screen Dpi Scaling

When I set my screen dpi setting to my preference that I desire (small), it works fine...

unitl my computer goes to sleep. After I wake it up, the dpi setting set my start screen to 150 and everything looks akward and big.

2. Also my touchpad has gone to dog crud and when I go to the setting to adjust it, but it wont let met. I've tried messing with the drivers, but no good :(

Could someone help me with this please? Microsoft please fix this! I'm running a Samsung series 7 ultra btw.
