I have a theory..and a few questions about desktop background images.

Im trying to speed my computer up and make it less likely for any lagging during start up..

I used to remember 15 yrs ago on older computers. that compressed JPG files were slower to open than uncompressed( or less compressed BMP files of the same number of pixels)

if i have a photo and use it as the desktop background. it was a compressed JPG 1600 by 1200 pixels buy mt monitor resolution is on 1280X 1024

Does that mean that windows has to resize every time i boot up?

Is it best to manually resize using photo editing software and shrink it to 1280 X 1024? so it doesnt have to resize??

Also, does using an uncompressd BMP, while using a little more ram, would it make it open faster than using a compressed JPG picture file as your desktop background?

I have 4GB ram so i dont have to worry about memory.

why not just uncheck un needed items from start up? Makes sense to me. Why worry about a jpeg?

oh i already did remove everything unnecessary from startup

Its just im trying to see which would be faster to start up the computer

im just asking a question. would a bmp be faster to open becuase its an uncompressed picture than a jpg?
i mean if its in memory and when you switch back and forth to desktop ,AND when you start your computer.. I just want to make my computer run more smoothly.

Do you or anyone else knows that could be true?

For a core2 quad processor with lots of RAM, it does not matter if you have a compressed background image or not. It does not matter if the image is larger than the monitor resolution, either.

What you should not do is to use background image with a size less than screen resolution. The smaller image will be enlarged to the screen size. In this case the image quality will deteriorate.
