First you will need a few things:
- Internet explorer or an internet browser able to go full screen
- The ability to use a 600 x 800 screen resolution
Okay, first thing's first. While it'll be full screen, it will not be improved graphics like the new Runescape will be in a week or so, but this will help for those reading now or those that don't have a computer that can handle the specs for the new detail.
First, what you have to do is right click on your desktop. Click “Properties” and click on the “Settings” tab. Change the little tab to the left (Which is 600 x 800 resolution).
Then open Internet Explorer. You may press F11 now, which will make the browser in full screen mode. Navigate to the java applet for Runescape at Runescape.com.
And there you go! Runescape is now in full screen mode. While it's just stretched out, it doesn't look any different than the normal sized resolution. Just make sure to revert to your original resolution when you're done.
Try again.
