So i recently moved to texas and i brought my computer with me on the plane. Well before i was using the exact build i have now on an apple monitor running games like GTA V at 45-55 fps and everything went smoothly. Well ever since i hooked my computer up to a new hp 27 inch monitor i most of my games have been lagging even games that shouldnt like overwatch. The only game i can run smoothly is League of Legends on very low. At first i thought it might have been that i switch to an HDMI cable but after trying it with a VGA cable i still get the same amount of lag. So im confused on if it is something to do with the monitor or if the Graphics card might be damaged which i doubt because i used a stability test and it seems to be fine. Any help is appreciated.
