    Game Performance Terrible when Playing on Main Monitor


    Hello Everyone!

    I'm desperately trying to fix an issue that I've been having ever since I got my new monitor. I can't even really describe the issue because I don't understand it. Basically if I am running a game on my main monitor, (https://www.amazon.com/27-inch-Monitor-PG278Q-Response-Display/dp/B00MSOND8C/ref=sr_1_2?ie=UTF8&qid=1483106497&sr=8-2&keywords=asus+rog+monitor) the frame rate is VERY laggy. My PC can more than handle any game (hearthstone, even a low graphic game such as Brawlhalla) that I've played and I feel like this has only happened recently.. Here is what I've done so far.

    Updated Graphic Drivers
    Monitor 1 set to Main display
    Set Monitor to Correct Refresh Rate
    Updates monitor drivers
    Ensured that gsync is pulling from GPU


    Here is the kicker... when I "minimize" the game by clicking on my second monitor, the game that is running on my 1st monitor (mentioned in link above) runs perfectly. No lag, no frame drops, nothing. The 1st monitor is running via Display port and the second is HDMI. Pretty standard but I can't figure out what is causing this issue. I don't know if it just isn't optimizing correctly. Any feedback would be perfect, thanks!

    Note: The only thing I can think of is that my monitor is set to 144h refresh rate and the games are not picking that up and they are bottle necking at 60 fps or lower
