The aspect ratio should be correct. As for TVs it is normal to crop a small frame around the image. Sometimes the TV has a TV/PC mode where it doesn't do cropping for PC. My old Motorola Atrix HD had an oversan adjustment that would shrink the image to compensate for the oversan. The G2 doesn't have such an option so if your TV doesn't either there's not much you can do.
I don't mind shrinking but the way it showing up on my TV I am losing some parts of the picture. for example I can't see 4G icon on landscape mode.
BTW, my TV says the signal is 1080p/60
