I have an hp pavilion f1703 flat panel lcd screen. When I boot knoppix regularly I get the 1024x800 res. When I boot with the parameters knoppix screen=1280x1024 the highest res is KDE is 1115x925 (or something similar). My moniter is made to run at 1280x1024 so anything other than that results in bluring. LCD's only work well on one res anyway...

Thanks ,

Alex
