If you're talking about images you trying to see, you'll have to reduce file and image size.
If it is screen resolution, (and I think that's the problem) you'll have to change that to higher res.
Ok this is what you can try..
Go to Start > Control Pannel > Double click on Monitors > Adjustments > There you'll see what your Screen Resolution and Color Depth is ( 16, 256, 16 bit or 32 bit)
Now Set the Color Depth to 16 bit ( I think it's already set at 16 bit) and Screen resolution to 1024x768 pixels (I think it's about 640 x 480 or 800 x 600 pix now..) That will fix your scrolling problem. Hope that'll help..
