I own a notebook with a 1920x1080 IPS screen. I was looking at the Sony Experia Z, which has almost the same screen resolution (1920x1200) in a store. Watching HD videos on youtube didn't look nearly as pretty as on my notebook though. Is that normal for tablets with HD screen resolutions? Is it perhaps because the screen isn't IPS or because slow wifi at the store actually made the video quality bad? I'm confused as to why it has the same resolution but doesn't look as nice.
