Help Unresponsive 'gap' in touch screen

[joelio1]

hey guys, just got my desire HD on friday and i've noticed a massive problem already. a part of the screen is unresponsive or just doesn't work properly. its a massive pain to try and type on and sometimes a button to press is in that gap on the screen so essentially you cant select it? a friend of mine has got an experia phone and he said he had the same issue but, when he did a 'manual update on his computer using software on phone ?' it fixed it. so i'm hoping this could be a software fix and hopefully not have to wait to send it back .
i hope you guys have heard of a problem like this and could really help me
Thanks
