With this you can "trick" it to being 1280x750 by boosting it 25%. This can make it to blurry for some, but it helps you run apps that need a higher resolution. For 1024x600, I find the sweet spot to be 35%, but everybody has different taste/eyes. It is not recommended, but you can go as high, or low if you pass a negitive number, as you want. Want 20000x20000, go for it. Don't expect to see much, but still. Go for it :).


-h This help
-p Pauses before running the command. Use with -v to see the command before it runs
-s The size to increase by in %, without the % (example -s 25). Default is 25
-v Gives more info as it runs";exit ;;
