Game Crash right before loading screen. Bugsplat. [CRASH]

So I just bought a new computer yesterday and was planning on using my TV for a monitor. I plug it in and it's fine I can play but the resolution doesn't look too great, it's a bit grainy so my cousin is letting me borrow one of his extra monitors and this is where the bug began. I try to play a game with my friends but as soon as champ select ends I get a black screen and it looks like the game is off the monitor a bit to the left and I immediately get a bugsplat error. I repeatedly try to reconnect to no avail. I went to the website's crash support and updated Windows, my drivers, JAVA, repaired client twice, you name it. I even tried ANOTHER computer monitor and once again the same exact error occurred. I decided to plug the TV back in because at least that way I can play and it works again. I have spent hours researching this and it seems I am not the only one with this issue. This is very frustrating and if anyone has an idea as to why this is happening please share. From what I have gathered it's something to do with the monitor or resolution maybe. Thanks.
