In whose opinion?
I usually view the forum on a desktop with a 19" 4:3 monitor. Very rarely - 5 minutes ago being the last time to see what happened - I view it on a 15" 4:3 laptop.
Why should they have compulsory different viewing settings?
Before anybody says it's my fault for using old technology, I never watch films, TV or any other media on a PC or laptop so a widescreen is useless and inconvenient to me. That's why I've got an old laptop and am seriously considering buying a spare monitor in case this one dies.
