Rectangular box when shooting video

[glospete]

My wife and I have identical DSC-HX90V cameras. But when I shoot video there is a rectangular box in the LCD monitor but it is not there on my wife's camera. The resulting movie seems identical but it really bugs me to find out why there is a difference. I have checked each and every Menu setting and cannot see any difference on any setting. Any ideas?

Have you try to press DISP?

Yes I have tried but on each display the box is still there!

and the box is also visible in the LCD viewfinder also.

Is an any kind of setting (I'm sure...), and if you try a Factory Reset?

Thank you. If I can't get any specific answer from the Community then perhaps that is my only option. Because of downloaded and installed apps on the camera I am rather loath to do this.

OK I did a Reset as suggested and that removed the box. But as I suspected that also removed the Apps which I had installed on the camera. And now when I go to reinstall them,under Display Account Information within Application Management it says The Account Is Not Registered but there is no apparent option to add my account. Any idea how I add my account to the camera?

Have you try to access via Web Browser from PC's?

There is the Access and then you can install the Apps...
