Hey I tried searching around and couldn't find anything, I've got the LG 34UC87 [3440x1440] and literally set it up today so I was going through and testing a bunch of things, HBO GO when you hit fullscreen just fills 1/4 of the right side of the screen with gray

Anyone know of anyway to fix this? Also it doesn't look 1440p, maybe it just hadn't fully buffered yet though, my internet has a few downloads going on it..

While I can't help you with the issue of the fullscreen issue (unlikely there'll be a 3rd party fix as well), for your 1440p resolution issue:

There are no manual video settings available for HBO GO. HBO GO will automatically adjust video quality based on the strength of your network connection. If you were downloading, it's highly unlikely you'll get anywhere near max resolution unless you have an incredibly robust internet connection.
