Yesterday I bought a 21.5" Full HD wide screen LCD monitor for my PC and realised that my desktop pictures being 4 x 3 proportions get distorted badly on a wide screen.
So I have reverted to a previous desktop picture but have added a wide screen 16 x 9 version.
Programs that show pictures seem to handle the different proportions OK but the Windows desktop does not have an option to show different proportion pictures properly.
I will do the same on the Eureka Models Blog desktop pictures that I do for Ron Cunningham.
I hope that this is of some use to you.
