This issue occured to me after updating my GPU Driver - I also only have one Monitor connected. There has to be anissue between the Game/ Driver, it certainly isn't due to lack of GPU Power on my Side - for me it also wasn't caused by Minecraft 1.8.7 (because I've already gone back to trying 1.8.4 which yielded the same crash)
