Windows Background Resize Issue

Hello
I noticed that if you have a large resolution image like 1920x1200 and your desktop resolution is 1440x900, the resizing that windows makes is pretty messy. For example google chrome does a way better job in displaying the image at a reduced resolution than windows. I have like 1000 background pictures so it would be a pain to edit each picture manually.

Is there a way to make the pictures look better without having to manually resize each picture in a different program?

at a closer inspection of the pictures that were actually messy i noticed it was actually the picture quality that was causing my issue. apparently high resolution pictures are not necessarily HD pictures as i were expecting. i think i should have checked that before starting this thread.

yes a good tip though i was aware of that. chrome makes a different picture in its cache memory to display in the browser if not enlarged. i still think that picture is a bit smoother than the pictures windows downsizes.
