I can't help you with your iPad issues as I'm a PC user. Hopefully someone with an iPad will be able to tell you how to set your device so the site opens up with the resolution you want all the time. Resolution is a device function, not a website issue.
As always, if you have specific problems, please use the Contact Us link, found at the bottom of every forum page, to request assistance from a site Administrator.
