Screen cut off...

[BlackLightShark009]

I'm having a slight issue and wondering if i'm missing something. That grey box that tells you your signed in or out for psn is cut off....i get the first word but the word in does not show fully. The only way i do see it fully is when i run it on a 4:3 screen. It's been doing this since i've owned the ps3 since launch. I thought maybe having 30in wide screeen was the cause but when i tried it on my friend's 46in widescreen it still does it and im using hdmi cable. It's not the biggest deal but i am curious bout why. I've gone through all my screen a adjustment options an none help. I'm guessing maybe i'd have to use the way the factory's options wich are not in the manual. Also i still can't fix warhawk screen cut off i'm wondering now if maybe the tube itself shifted and is now lopsided. Would there be a easy way to fix that myself or best to take it to a shop? I'm hoping it's not actually shifted and i don't know how it would have been considering it did'nt start doing it till after bout 2 weeks later. I had carefully move my tv into a different room. I've had warhawk since it came out and never had this issue till couple months ago. My tv is a crt. Thanks in advance to anyone who can give me any helpful info.
