Hi there.
Here is a site that IMHO has amazing wallpapers. You can either subscribe to it, or just get the free ones. There are a lot of free ones, and very good quality so it should be good for larger monitors. Let me know what you think.

The site is kinda hard to find your way around, look on the left nav bar for the top10 and on the right side for the newest releases (both members and non-members) And, the membership isn't too bad...it's only $25 for a year, Personally I think it's worth it, but whatever.

Enjoy!

interesting that people would actually PAY for walls, considering the abundance of freebies available on the interwebs... but good link regardless

cheers!

Not to mention if you just Google them you'll probably find 42 copies ready to download.

OMG People ACTUALLY pay for wallpapers?

Man I should throw all of mine up for sale.
