I've played minecraft for many years and this never bothered me until now where i made a cool 32x32 resource pack. I started playing and I really wanted to see the whole item but couldn't because its cut off by the screen border and the only way to see the whole item is in windowed and that's just kinda ugly on my medium gaming sized monitor yes I Googled it but to no prevail. (I also don't know which words to search, i tried my best) Even resizing my hud didn't work! . I really want to see the whole item but I just can't!
You'd be more likely to get help if you posted something that made sense.
I'm guessing that you are complaining about not being able to see the whole object in your hand? How much of this object you can see depends upon the aspect ratio of the screen / window. If you can't see the whole item it's because your screen is not wide enough, or stating it another way but meaning the same thing, your screen is too tall for its width.
Or in yet more words because your aspect ratio is off you areseeing the difference between widescreen and fullscreen, aka black bars versus cropping.
